Tech Tree Notes:

Spoiler

• This tree utilizes an incomplete German Tech Tree as a reference. The only other option would be the USSR tree due to the Polish People's Army adopting several Soviet-era vehicles. The choice was due to Poland and Germany having a long history of vehicles, with Germany using several captured Polish creations, to East Germany and the Polish People's Army both using Soviet vehicles. In modern times, Poland went on purchasing several German Leopard 2 main battle tanks as well as customizing their own, being the Leopard 2PL and Leopard 2PLM. In it's current state, politics aside and with Gaijin starting to add more East German vehicles which some Poland had used, the German tree is the best bet for a Polish Sub-tree if Poland as an independent nation is not implemented. Not to mention, Poland has some representation in the German tree as it is with the Leopard 2PL.
• I added more East and modern German vehicles to fill out the tree more to show more inclusion for Poland if it were added. As stated previously, Poland utilized a lot of the same vehicles as Germany through both the Cold War and Modern times. Both nations compliment each other well.
• Some German vehicles were swapped around to improve the transition between Soviet and West German vehicles. Other vehicles such as the Gepard were upgraded to the Gepard 1A2 which includes a Laser Rangefinder and FAPDS-T rounds, the KPz-70 moved to the Leopard line, the PUMA upgraded with Spike-missiles resulting in the PUMA S1, the Leopard 2PL moved to the research tree and replaced by the PT-91M Pendekar, and more.

Description and Inspirations :

Spoiler

• The Polish Military has a long and intricate history, dating back to the 10th century. Throughout the centuries, the Polish Military has undergone significant transformations, adapting to changing political, social, and technological environments. In the early years of Poland, the military was primarily composed of knights and noblemen who served in the cavalry. This tradition continued into the 16th and 17th centuries, when Poland became a major European power under the reign of King Sigismund III. During this period, the Polish Army was renowned for its skilled and heavily armored cavalry, known as the Winged Hussars.

  In the 18th century, Poland experienced a period of decline and political instability, leading to a series of partitions by neighboring powers. As a result, the Polish Army was disbanded and its soldiers were forced to serve in the armies of other nations. In the early 20th century, Poland regained its independence, and with it, a new military was formed. During World War I, Polish soldiers fought on multiple fronts, and after the war, the country's military underwent significant modernization, including the introduction of armored vehicles, aircraft, and machine guns. During World War II, Poland was invaded by Germany and the Soviet Union, leading to the formation of a resistance movement. Polish soldiers fought in multiple theaters of the war, including the Battle of Britain and the Normandy landings. After the war, the country's military was reorganized by the Soviet Union and the Polish People's Army was established as the country's primary military force. Following the collapse of communism in 1989, the Polish military underwent significant modernization and restructuring. The country joined NATO in 1999, and since then, the Polish military has played an active role in numerous international peacekeeping missions, including in Afghanistan and Iraq. Today, the Polish Armed Forces consist of the Polish Army, Polish Navy, Polish Air Force, and Special Forces. The military has undergone significant modernization and expansion in recent years, including the acquisition of advanced weaponry and equipment. In conclusion, the history of the Polish Military is a testament to the country's resilience and determination in the face of adversity. From its early days as a cavalry-based force to its modern-day role as a member of NATO, the Polish Military has evolved to meet the challenges of each era. With its highly trained soldiers and modern equipment, the Polish Military continues to play an important role in ensuring the security and stability of the country and the wider region. 

• There are several other vehicles that are not a part of this sub-tree rendition. This isn't because I didn't think of adding them, it is because I just to provide a rough basis for the tree.

  Hope to see a Polish Tech Ground Force, Air Force, and Coastal Water Tech Tree!

 

Editor's Comments/Reasoning:

• My main reason for creating this tree is the same of my Republic of Korea Sub-tree which can be found below. It's to find a way to add these nations in the game IF Gaijin (not myself) deems the nations as not having a sufficient amount of vehicles to create an independent tree even though there's very well made community options for a Polish Independent Tree (or options like the very nicely made Visegrád Group Tree). I tried my best to provide additional alternatives in the case that these nations are put on the back burner even though they have their own significant capabilities and uniqueness. I'm a very strong proponent for not splitting individual nation's vehicles amongst many trees as that hurts those nation's players and want to offer the best experience I can for them if the option of a full tree does not work for developers. So please, feel free to criticize the sub-tree's so I can further enhance them for players needs and wants but don't hate because of political standpoint or related points, my focus is an apolitical standpoint similar to Gaijin . I made these trees in terms of trying to find the best place for them in the current in-game situation, especially since there's a Polish vehicle already in this tree. This does not mean these sub-trees cannot be applied to future nations that have not made it to the game yet. If you have additional options, feedback, or want to contact me personally for additional inquiry, feel free. Thanks!

• Description : 
  • The Samochód pancerny wz. 34 was a Polish armored vehicle designed and built in the 1930s. It was the main armored reconnaissance vehicle of the Polish Army prior to the outbreak of World War II. During the German invasion of Poland in 1939, the Samochód pancerny wz. 34 was used extensively by Polish armored units, particularly in reconnaissance and counterattack roles. However, the vehicle's light armor and armament made it vulnerable to German anti-tank weapons, and many were destroyed or captured by the enemy. The Samochód pancerny wz. 34 had a crew of four, including a driver, gunner, and two machine gunners. It also had a radio, which was a relatively new technology at the time and gave the vehicle a significant advantage in communication and coordination on the battlefield. The variant recommended for in-game use is the the vehicle armed with the 37mm wz. 18 gun.

The 7TP, named for 7-Ton, Polish, was a light tank that served in the Polish Army until the end of the Invasion of Poland by the Soviet Union and Nazi Germany. The 7TP was considered revolutionary due to its powerful diesel engine, commander’s reversible periscope, the 37mm anti-tank gun and radio equipment. It was considered Poland’s only tank during the war due to others being classified as tankettes.  108 single-turret models were ordered and used in-service at start of the war. It received further upgrades sometimes earning the name 9TP.

• Description : 
  • The TK, or tankette was a series of tankettes produced in Poland starting in 1931. When first introduced, they had good armor and a decent engine giving them high survivability. However, by the time the Invasion of Poland began, they were largely obsolete versus the several turreted, high speed Panzer I's, II's, III's, and IV's of the German Army. In 1937, the FK Rifle Factory in Warsaw built a new 20mm automatic cannon known as the model  A. This weapon would be accepted into service as the 20mm w.38. This cannon was used to rearm TKS tankettes to increase their armor penetration power. This model would be known as the TKS 20. The TKS 20 was a tank destroyer variant in-service with the Polish Army in mid-late 1939 and was used in the defense of Poland during the September campaign. However, there development came late as there was not enough to turn the tide of war. Only 3-5 were in-service by the time of the Invasion of Poland and complimented the 7TP and other TK variants.
  • There were accounts on September 18th, 1939 near Pociecha that a group of TKS 20's and there machine gun counterparts knocked out a patrol of 3 PzKpfw 35(t)'s without any losses.

However, by the time the Invasion of Poland began, they were largely obsolete versus the several turreted, high speed Panzer I's, II's, III's, and IV's of the German Army. The TKD tank destroyer was a prototype armored vehicle developed from the TK tankette by Poland in the late 1930s, shortly before the outbreak of World War II. It was armed with a 47mm main gun, designed to counter the growing threat of German armored vehicles and tanks, which were becoming increasingly dominant on the battlefield. Only 4 were created with none of them left today.

• Description : 
  • 75mm Dion Bouton wz. 18/24 was a self-propelled gun that was based on a modified French truck chassis. The wz. 18/24 was used as a mobile artillery piece, providing fire support to Polish infantry units as well as a anti-aircraft vehicle. Its self-propelled design made it highly maneuverable on the battlefield, and it was able to quickly move to new firing positions to avoid enemy counterfire. During the Polish Defensive War of 1939, the wz. 18/24 saw extensive service in the Polish Army, particularly in the early stages of the conflict. However, like many of the country's military assets at the time, it was outmatched by the German Army's more advanced weaponry and tactics. They were used alongside PF621Ls.

• Description : 

  • The MT-LB-23M Krak prototype was developed by Huta Stalowa Wola, a Polish defense company, in the early 1990s. The company developed the vehicle by mounting a GSh-23L autocannon on top of the MT-LB vehicle.  The GSh-23L autocannon was developed in the Soviet Union and was widely used by the Soviet military and its allies. It is a highly effective weapon, capable of firing up to 3,400 rounds per minute and is used primarily as an aircraft cannon.  The MT-LB-23M Krak prototype was intended to serve as a multi-purpose weapon system, capable of providing fire support for infantry troops and engaging light armored vehicles and low-flying aircraft. However, the project was not pursued further due to a lack of funding and changing military requirements.  The MT-LB-23M Krak prototype is an example of how existing military vehicles can be modified and upgraded to meet changing operational requirements. The GSh-23L autocannon provided the vehicle with a significant increase in firepower and versatility, demonstrating the potential of the MT-LB platform for a range of weapon systems.

• Description : 
  •  The OT-64 (Obrneny Transporter) Armoured Personnel Carrier (APC) was jointly developed from 1959 by Czechoslovakia and Poland was used by them in place of the similar Russian BTR-60 (8 × ? APC. The vehicle, which uses many automotive components of the Tatra 813 series of 8 × 8 high-mobility trucks, entered service in 1964 and was subsequently widely exported. The Polish designation for the vehicle is the Sredni Kolowy Opancerzny Transporter. Tatra of Czechoslovakia provided the chassis and automotive components and FSC/Lubin in Poland the armoured body and weapon system. The OT-64 SKOT-2AM was the anti-tank model of the OT-64 SKOT-2A that was equipped with 2 AT-3 Sagger launchers, each located on both sides of the turret, covered by a thin layer of RHA to protect against up to 7.62mm small-arms fire. It can also be equipped with the 73mm SPG-9 Anti-Tank Grenade Launcher and carry 30 PG-9W rounds. This would have to be operated by 4 crewman. Production of the OT-64 family was completed in 1990 after about 10,300 had been built for the home and export markets. Only around 28 were converted to the OT-64 SKOT-2AM. :

• Description:
  • The KTO Rosomak is an APC developed from the Patria AMV in 2001. The Rosomak, meaning “Wolverine” went into serial production beginning in 2003. Variants include a Combat version (known as the Rosomak-M1 or M1M) equipped the Italian OTO Melara HITFIST 30P turret, featuring a 30mm Bushmaster Mk.2 Autocannon as well as indigenous upgrades such as the new 81mm Smoke Grenade Launchers, a transport version with multiple RWS capability known as the Rosomak-M2 and M3 models, the M120K Rak Mortar system and more. The Rosomak-M1 is the primary version, having 836 equipped for multiple mechanized brigades. In 2007, 24 Rosomak-M1’s were upgraded to the Rosomak-M1M standard in preparation for deployment to Afghanistan including additional steel/composite applique armor, Qinetiq RPGNet armor, Duke anti-IED system, and Blue Force Tracking BMS.
  • There is also a turret replacement with ZSSW-30 unmanned turret including 30mm Bushmaster Mk. II Autocannon, Coaxial 7.62mm UKM-2000C GPMG, 4x 81mm 902A ZM Dezamet Smoke Grenade Launchers, and a Spike-LR dual ATGM launcher. In March of 2013, developmental work began from Armament Inspectorate with a consortium of Huta Stalowa Wola SA (HSW) and WB Electronics SA and in 2019, tests were completed on a prototype turret. In 2020-2021, after delays due to COVID-19, test firings of the ZSSW-30 with Spike-LR launcher were successful with possible procurement in 2022-2023 post-qualification testing. Currently 1 prototype is available.
• Notes:
  • It’s clear which variant of the KTO Rosomak IFV is better, however, I added both due to one in serial production and, the other is in testing and uses Spike ATGM’s which are currently taboo in-game due to the Fire and Forget capabilities.

• Description:

  • The BWP-2000 was a prototype IFV, and only a small number of vehicles were produced for testing and evaluation purposes. The vehicle was never put into mass production or adopted for service by the Polish Army. The BWP-2000 was developed in the early 2000s as a successor to the BWP-1, but its development was ultimately abandoned due to budgetary constraints. The vehicle was based on the chassis of the SUM Kalina minelaying vehicle and was designed to incorporate a range of modern features and upgrades, including advanced armor protection, a powerful 30mm autocannon, and a thermal imaging sight. Later on, testing occurred with the vehicle using a T-60/70A turret developed by OTO Melara armed with 60mm high-pressure gun.

• Description:
  • The AMZ Kutna Bóbr-3 wheeled vehicle family is an under development replacement platform for the BDRM-2 for the Polish Army. The vehicle has a 326hp 6-cyl Diesel Engine and has full amphibious capabilities. A model was created that incorporated a Rafael ADS Spike Dual ATGM launcher that can carry 4x Spike missiles. The vehicle also has 8x 81mm Smoke Grenade Launchers covering 360 degrees and KenBIT SOL-2 Laser Warning System. The vehicle was developed for the Ottokar-Brzoza tank-destroyer program, however was not selected to be the next generation tank destroyer due to the Polish Army's selection of the MBDA Brimstone Missile as the new primary ATGM missile. This however, does not make the AMZ Kutna Bóbr-3 TD any less capable as it features capabilities that can destroy light vehicles, main battle tanks, and even helicopters. The AMZ Kutna Bóbr-3 TD has not entered service with any country.

• Description : 
  • The T-72M1R is a modernization of the Polish T-72M1. In 2011, the Polish MOD set two contracts to modernize the PT-91 Twardy and the T-72M1 main battle tanks of the Polish Army. More specifically, the T-72M1 received a multitude of upgrades including a new W-46-6 Diesel Engine with Digital Starter, new KLW-1 3rd-generation Thermal Camera for the Gunner, , new optics for the Commander, new power supplies, digital communications, and much more. These upgrades were designed to prepare the T-72M1, in the time of war, to be reintroduced into the Polish Army. This upgrade resulted in the designation T-72M1R. Since the start of the conflict in Eastern Europe, Poland has donated much of its T-72 inventory including the T-72M1R to Ukraine. These T-72M1R's either come standard, or have been modified to equip Kontact-1 ERA with or without the 81mm smoke launchers. It is unknown how many T-72M1R's remain in service with Poland, however the tank is used by both Ukraine and Poland.

• Description : 
  • Developed in 1991 by the Ośrodek Badawczo-Rozwojowy Urządzeń Mechanicznych and produced in 1995 (until 2009) by the Bumar Łabędy Company, the PT-91 Twardy is a Main Battle Tank designed to replace the T-72 series tanks left over from the Soviet Union. Created from the failed “Wilk” program, the PT-91 is a heavily modified T-71M1 that implemented a new DRAWA-1 fire control system, new ERWA-1 (and now ERWA-2) reactive armor, new engine, transmission, and new autoloader with a rate of fire of 8-10rds per minute. Remaining T-72’s in Polish service are due to be upgraded to the PT-91 Twardy standard. The PT-91 is still in service and compliments the Leopard 2PL and the new M1A2 SEPv3 main battle tanks. The PT-91 also continues to receive minor upgrades such as the replacement of the original gunner sight with the Elbit Systems TES sight, with another replacement being the ZMKT System w/ KLW-1 Thermal Camera. Roughly 285 produced and are in service. Current plans to upgrade PT-91 Twardy’s to the M2 standard.

• Description : 
  • The Poprad Very Short-Range Air Defense System (VSHORAD) is a mobile air defense system designed by the Polish Defense company known as Elektronika. This system was designed to counter low and medium flying aircraft with infrared missiles. Two missiles can be used with this system, the GROM-1 designed in the 1990’s and the GROM-M/Piorun missile, an upgraded GROM-1 that was designed around 2015. This system is mounted mainly on the AMZ ŻUBR Light Tactical Vehicle. This AMZ ŻUBR and Poprad combination is designated the ŻUBR-P. 2 This system does not require the use of a RADAR and can operate independently utilizing the Electro-optical KTVD-1M Thermal Imager which is integrated with the Fire Control System allowing auto-tracking and engage capability. Using this capability allows the Poprad system to remain undetected. The Poprad can also integrate with the ŻUBR MMSR which utilizes a Soła N-26 radar mounted on the AMZ ŻUBR chassis for searching and tracking information. Currently the Polish Army received around 79 units and are currently in service.

• Description : 
  • The PT-91M2A1 Twardy is a modification of the PT-91 Twardy that could be selected to be become the standard Main Battle Tank along with the Leopard 2PL and M1A2 SEPv3 . The program to enhance the already existing PT-91 Twardy began after the military declined the PT-16/PT-17 main battle tanks due to affordability, therefore a new program with the tank designation PT-91M2 was formed. This program would lead to two variants of the PT-91M2, the A1 version which is designed to be cost effective as well as incorporate new digital technologies, and the A2 version which is designed to bring out the most of the PT-91 Twardy platform. The A1 version is not to be ignored however, still incorporates a significant amount of new technologies as well as enhancements to crew survivability and firepower. Some advancements of the A1 include upgraded TIFCS-GS Thermal Sight for the gunner and the Elbit Remote Control Weapon Station featuring a 12.7mm HMG (w/ Hunter-Killer mode), Slovakian 2A46MS 125mm smoothbore gun, rear APU, enhanced LWS, rear slat armor, and more. The PT-91M2A1 still features the same ERAWA-2 ERA that is found on the original PT-91 Twardy. One significant takeaway is that the Polish Army is in a bidding process to replace the old Soviet APFSDS-T rounds still in service with the Polish Army. Leading the bids is the Elbit Systems MK-1 APFSDS-T round with enhanced penetration. This round would be used with either the A1 or A2 variants of the new PT-91M2. Decision on the A1 or A2 models are in still in progress and is due to be accepted into service within the next 3-5 years, however due to the conflict in Ukraine, it is unknown if Poland will continue the program or will reduce its expectations.

• Description : 
  • The PT-91M2 (A2 version) Twardy is a Polish Main Battle Tank that is due to become the standard Main Battle Tank along with the Leopard 2PL and M1A2 SEPv3. The program is designed to upgrade existing PT-91’s as well as T-72’s to this standard. Due to financial constraints with the PT-16 and PT-17 tank programs, the PT-91M2A2 program was designed to be cost effective while allowing major advancements in technology on the old platform. There is a cheaper cost-effective program offered by Elbit Systems which retains the original engine plant and more that is known as the PT-91M2 (A1) model. Some advancements of the A2 include upgraded SAVAN-15 FCS (w/ Hunter-Killer mode), PASEO Commander Sight (and SOD-1 omnidirectional cameras for the Commander), Slovakian 2A46MS 125mm smoothbore gun, rear APU, enhanced LWS, rear slat armor, and more. One of the key factors that separates this from the PT-16/17 is the use of the same ERAWA-2 slabs found on the PT-91 base model and no new composite armor. This will decrease the overall effectiveness of the MBT vs. others. Currently there is a bidding process for a new APFSDS-T round that will replace current Soviet designs. Leading the bids is the Elbit Systems MK-1 APFSDS-T round with enhanced penetration. Decision on the A1 or A2 models are in still in progress and is due to be accepted into service within the next 3-5 years.

Ottokar-Brzoza TD

Spoiler

An Ottokar-Brzoza tank destroyer concept unveiled in 2019, this variant is based off of the BWP-1, or also known as BMP-1 and utilizes a RCWS for point-defense.

Another concept that utilizes the Borsuk IFV chassis both of which fire the Brimestone missiles.

• Description : 

  • The Ottokar-Brzoza program is a joint venture between Poland and the United Kingdom, and it is named after two famous military commanders from Poland and the UK. The goal of the program is to develop a highly mobile and versatile tank destroyer that can provide direct fire support to infantry units and engage enemy armor at long ranges. The primary focus of the program is introducing the Brimestone missile developed by the United Kingdom, itself a further development of the American Maverick missile, into a Polish-developed chassis. The tank destroyer will also be equipped with advanced systems, including a laser rangefinder and a thermal imaging system, which will allow the crew to engage targets at long ranges and in low-light conditions. The vehicle is expected to have a crew of three, including a driver, a gunner, and a commander.

• Additional Notes:
  • The BWP-1 concept would be best used at this time due to the fact it has a RCWS offering a similar playstyle to the Strike TD in-game. All other variants lack optical systems at all.

Leopard 2PL (M1)

Spoiler

Leopard 2PL conducting exercises.

• Description : 
  • Prior to 2015, Poland had received 142 (in different intervals) Leopard 2A4’s from the German government. The Polish Military, realizing it needs modernized main battle tanks for its borders, contracted Rheinmetall to upgrade the Leopard 2A4’s but were limited by a 60t weight factor. This resulted in the turret receiving new electronics such as thermals, and fire control equipment, as well as an AMAP (Advanced Modular Armor Protection) kit, greatly increasing armor protection. However, by the time the 60t weight limit was reached, only the turret had received the new armor protection as the hull remains the same. Possible armor plating was incorporated on the bottom of the hull to protect against IED’s. The Leopard 2PL is currently in service as of 2020, with more Leopards, including Leopard 2A5’s being selected for the upgrade process. The Leopard 2PL has received a small modernization with the new nomenclature Leopard 2PL M1 which focuses on internal systems such as Troop Thermal Identification software, Cold Start capabilities, Active Cooling System dubbed "EWNA", and more.

I feel you're going to find very little support among the polish community for this particular endeavour. Mixing the polish with ze germans is not a good look.

A side branch to the french (a number of early french tanks were bought to bolster the polish forces, most of the polish aviators served in the french air force before the fall of France, Wicher class were essentially Burrasques, there's a lot of low-tier commonality, plus the french are currently underdeveloped compared to other choices) or the brits, for obvious reasons.

I agree for the most part, but I was trying to look at this from a non-political standpoint due to the fact there is so much influence from Germany. From a political standpoint, today they're close, NATO, and European Union allies but there are several difficulties and some severe from the past. From a non-political perspective, they fit really well with the Leopard 2PL, Leopard 2A5, Leopard 2A4, BMP-1, already in-game (they could get Polish camouflages), Future Soviet vehicles both nations used, etc. and many others but from a political perspective, its a little more difficult for obvious reasons. I was looking at other nations to implement this but going into the modern section of the tree having both a German influenced tank like the Leopard 2PL or the Soviet influenced PT-91 in any other tree didn't fit so well. The only reason this works is that that Gaijin has plans to implement (parts of) an Eastern Germany Tree. This Tree was just another way to gather support to have Poland implemented in some way or form in the game if a full tree doesn't materialize. Besides giving Poland it's own tree, or attaching it to Germany as a sub-tree, I don't know where else it could go besides breaking it up into other trees which I know a lot of people don't want (neither do I).

Changed the title so it can be implemented to any tree. Thanks for the opinion!

 

Just for the record, Gaijin is apolitical and you already have the Leopard 2PL in the German tree. There’s a lot of hate towards this tree because it isn’t exactly what “people want”. A lot of research has went into this tree and I made it as an alternative so we have options for Poland’s implementation. Valid argument is one thing but crapping on the tree with nothing else to say isn’t worth anyone’s time. Offer constructive criticism in a respective manner or take it somewhere else.

I want to see Poland in War Thunder, but not like this. I'd rather them have a full tree. Something that truly shows how vast Poland's endeavors are.

[RazNaRok 616]

Consider addition of polish production tanks:

T-34-85 M1 - crew reduced to 4 with 3 crewman and radio in turret, hull MG remotely operated by driver, increased ammunition storage and a modernized propulsion and fuel system

T-34-85 M2 - additionally adapted for deep water wading, had a night vision equipment for commander and driver 

T-54A prototype with anti HEAT armor - so called Product S-2, with additional front and turret armor meant for defense against HEAT shells,

T-54AM1 - adapted for deep water wading, increased amount of artillery ammunition and a modernized propulsion and fuel system.

T-54AM2 - later designated T-55U, had two planes gun stabilization, increased amount of artillery ammunition, new W-55 engine, hydraulic power steering and TAD smoke generator.

 

The T-34, T-54 and T-55 produced in Poland were intended not only for the needs of the Polish army. A large part of them was intended for export, not only to the Warsaw Pact countries, but also to friendly countries, especially from the Middle East. The vehicles produced in Poland enjoyed a very good reputation and were rated higher than tanks of the same type produced in the USSR.

You can keep the 7TP reinforced (the prototype by BBTBrPanc), although there are no photos of build prototypes.

Survived only comparative sketches and some technical documentation of both prototypes, with some "artistic creativity" those could be enough to create reliable reconstruction and game models.

 

However as those were only two purposefully build prototypes and third comparison vehicle build from non finished C7P tractor, those can be consider only as candidate for a premium vehicle.

 

 

 

9TP - an unofficial name for the improved 7TP tank , ordered by the Polish Ministry of National Defense in 29th June 1939 and planned to be produced since autumn 1939.

 

It is also known as  7TP wzmocniony (7-tonne Polish, reinforced) and  7TP wz. 1939 (7-tonne, Polish, mod. 1939) , after the names of two prototypes.

Certain non reliable sources claim that 7TP wz. 1939 version entered mass production in September 1939.

 

Protracted designing-construction works of Polish tank prototypes and the lack of ability to furnish army with modern equipment from abroad gave the foundation for a huge 7TP development in 1938. This programme was mainly aimed at increasing tank’s military value throughout strengthening its armour and (due to envisaged weight increase) using much more reliable powertrain which was supposed to maintain good manoeuvrability and traction performance. In the mid-1930’s, a large experience had been collected, and significant achievements in the field of producing armour plates were reported. Employees of Laboratorium Mechaniczno-Chemiczne BBT Br. Panc. (Mechanical-Chemical Laboratory of Armoured Weapons Technical Research Bureau) in cooperation with Komisja Badania Blach i Płyt Pancernych Instytutu Metalurgii i Metaloznawstwa (Commission for Research of Armour Plates and Sheet Metals from the Institute of Metallurgy and Metal Science) and metallurgical industry representatives had carried a lot of arduous studies followed by endurance tests of homogeneous and cemented (case-hardened) armour. Owing to the fact that Polish industry had short tradition in manufacturing modern plates, such issue was considered as a top priority. These researches led to work out and master mass production of 3-50 mm thick homogeneous armour plates, and also 8-20 mm thick cemented ones.

 

What was crucial for tanks’ mass production was that metallurgical achievements had made it possible to devise new methods of welding such huge components as hull. In 1937, on the basis of tests results, Maj. Eng. Tadeusz Biemacki, the manager of metallurgy department in Labolatorium BBT Br. Panc., designed and accomplished 7TP’s experimental hull, made of 5-17 mm thick welded armour plates. It weighted around 1700 kilograms — significantly less than hulls built with the previous method, i.e. through superposing plates on a grit formed frame, and, later on, merging them by rivets or screws.

 

Furthermore, some steps forward in the field of combustion engines had been made. In 1936, the engineers from BS PzInż (Studies Bureau of the State Engineering Works) — Jan Werner, Jerzy Dowkontt, Wacław Cywiński — created prototype power plants of own design, including the PzInż. 705 carburetor engine (indicated for a new family of lorries), and its derivative modification: the PzInż. 725 (more powerful, designed for heavy goods tracked vehicles). Data sheet of PzInż. 725: 345 kg, 6-cylinder inline vertical, cylinder bore x stroke: 100 x 110 mm, capacity: 5180 cm³, 95 HP at 2800 rpm, compression ratio: 6.35.

 

By 1939, several prototypes of this engine had been built; although they were factory-tested, it was impossible to gain some experience from long term exploitation. Accordingly, at the beginning of 1938, the State Engineering Works received the brand new Saurer CT1D diesel engine, and its bulk production was about to be launched under the designation PzInż. 155. Data sheet of PzInż. 155: 600 kg, 6-cylinder inline vertical, cylinder bore x stroke: 100 x 110 mm, capacity: 7980 cm³, 100 HP at 1800 rpm, compression ratio: 16. The Saurer Company provided complete documentation and several model engines.  The production start-up was foreseen for 1939.

 

In April 1938, the Armoured Weapons Command ordered in the State Engineering Works a prototype 7TP tank with such power plant. One month later, it was finally built and delivered to Armoured Weapons Technical Research Bureau (the sample was probably made of iron plate).  The tested vehicle (loaded with extra weight in order to simulate heavier armour) was considered as better than the one with PzInż. 725 engine. Its only disadvantage was that the newer motor showed less abilities to overcome rough terrain capabilities, which were caused by weight increase, while keeping the same chassis.

 

The proposals for further 7TP modernization were presented in two projects:                                                            

– the first, proposed by Armoured Weapons Technical Research Bureau (7TP reinforced): this modification provided newly developed Polish PzInż. 725 petrol engine (95 HP), which was smaller than the diesel one, and welded hull, of a lower profile, with a slanted front plate of the combat compartment. The brand new power plant was mounted on a right side of engine compartment (a drive shaft was also moved to right side, so it would be less an obstacle for the turret's crew). What is more, the cooling system had been significantly changed: its cooling grates were removed from an engine deck, and replaced with slots in sides. The motor's mass had an influence on reducing overall tank weight. All these qualities weighted in favour of PzInż. 725. On the other hand, the use of petrol increased the risk of fire, and tank would be ignited by direct hit. The armour, while maintaining the 7TP's weight and traction performance, was to be up to 30 mm in front and rear (vertical plates), 25 mm on a front slanted plate and the driver's hatch, and 20 mm on sides and turret. The driver was to be equipped with two G wz. 34 reversible periscopes. 

 

– the second, proposed by Studies Bureau of the State Engineering Works, worked by Edward Habich (7TP mod. 1939): in this variant, the PzInż. 155 engine was used. The tank hull shape was slightly different, in comparison with the 7TP; only armour thickness increased from 17 mm to 40 mm in hull front, from 17, 13 and 9 mm to 25, 20 and 13 mm respectively in sides, and from 15 to 20 mm in turret's sides and to 40 mm in turret's front. Weight also increased to 10 594 kg, so strengthened suspension (320 mm wider tracks, road wheels with replaceable rubber), and C7P tractor's transmission were proposed.

 

Both project were submitted for consideration in May 1939. Despite the fact that the State Engineering Works draw heavy criticism from Col. Patryk O'Brien de Lacy (the head of AWTRS), its solutions gained Armoured Weapons Command's approval. Two prototype light tanks named 7TP mod. 1939 were ordered. In July, these vehicles (with some different adjustments — the one had standard transmission, the other adopted from C7P tractor) were finally built and received by Military Technical Inspection. Since 28 July, in the Kampinos Forest, tanks had been investigated and subjected to comparative trials with the third vehicle (it was to be experimental 7TP with CT1D engine, or another prototype tank called PzInż. 725).

 

During the first drives, the prototype with C7P's transmission obtained the best results and performance, so it was supposed to be launched in mass production. Unfortunately, the outbreak of the Second World War foiled these plans.

 

At the beginning of September, two or three experimental 7TPs mod. 1939, along with several different prototypes, were assembled in the WD BBT Br. Panc. (the Experimental Workshop of AWTRS), and in the SEW in Ursus (former Czechowice) near Warsaw. There is no information whether they were evacuated or stranded (damaged or concealed).

 

The genesis of 7TP reinforced/ 7TP mod. 1939:                                                                                                                  

 

– 1932:                                                                                                                                                                                  

The beginning of designing a homegrown light tank based on Vickers tank; it had been marked as VAU-33 (Vickers-Armstrong-Ursus).

 

– 1933:

Agreement between AWTRS and the SEW for ordering in the SEW two made of steel prototype tanks, according to the VAU-33 project.

 

– 1934:

August — completion of an early transitional model in line with VAU-33 project; it was implied as PzInż. 120 (7TP twin-turret), carried no. 1595, and a nickname Smok (Dragon). Intensive trials and comparisons between PzInż. 120 and Vickers tank.

 

- 1935

August – second iron prototype, reg. No. 1596, according to VAU-33 Słoń (Elephant) design is completed.  The tank was handed to CW in Modlin and then to 3 Bat.Panc. in Warsaw for training purposes. During the year many improvements were introduced to the Smok, which, as prototype, was still at a disposal to BBT Br. Panc.

 

- 1937

January – Bofors turret was mounted at the iron Smok. The procedure was conducted in Warsztaty Doświadczalne BBTech. Br. Panc. The vehicle was given designation PZInż 220 as a single-turreted version of the 7TP tank. Basing on earlier experiments,  mjr inż. Tadeusz Biernacki, director of the metallurgy division of the Laboratorium BBT Br. Panc., designed and manufactured prototype hull for the 7TP tank. It was made from steel plates with thickness from 5 to 17 mm welded together and weighted 1700 kg. 

 

- 1938

April

The DBrPanc. ordered prototype 7TP tank with experimental Saurer CT1D/PZInż 155 engine from the PZInż.

 

May

Circa 25.05.1938 the 7TP prototype (reg. no. 1766) with the CT1D was handed to  BBT Br. Panc by PZInż for testing purposes. The tank had additional ballast attached in order to simulate the weight of the thicker armour. The tests were conducted in autumn of 1938 in Kompania Ćwiczebna Centrum Wyszkolenia Br. Panc. The tank number 1766 traversed 548 km during tests, the engine worked for 29 hours and 55 minutes. The CT1D was considered better than VBLDb, but the offroad capabilities were worse as the current chassis was kept.

 

- 1939

March

18.02.1939 or 21.03.1939 – the protocol from the tests of the prototype 7TP PZInż with the engine CT1D was written and the tank was rated well. The tank without mock-up ballast imitating the strengthened armour was 210 kg lighter than standard 7TP. The decision regarding further development — altering the design of the vehicle and adding additional armour — was made. Two parallel projects were started: BBTech Br. Panc and PZInz.

 

April/May

Presentation and evaluation of two projects (not final vehicles!) of the 7TP reinforced/9TP was conducted. Despite the criticism of design choices proposed by the PZInż by the BBTech Br. Panc., the commission of Dowództwo Br. Panc.approved the vehicle proposed by the PZInż.

As result, two prototype vehicles were ordered from the PZInż, called 7TP wzór 1939. The changes were to be introduced on two 7TP tanks being in on-going production, perhaps immediately with full-featured armour plates (as proposed by the BBTec Br. Panc). The BBTech Br. Panc made a single vehicle according to their own project using  iron plates based on the parts belonging to the first model 7TP tank (most probably the iron Smok still in possession of the WD BBTech Br. Panc.).

 

July

28/31.07.1939 and 03.08.1939 - the tanks were given for acceptance and tests to the military.

Vehicle no. 1 adhered to the proposal by the PZInż but was equipped with standard gearbox from 7TP. The PZInż vehicle no. 2 fully adhered to the PZInż proposal from May/April 1938, as it employed gearbox from C7P. The third vehicle was presumably the experimental 7TP with the CT1D/PZInż 725 engine. The best results were achieved by the PZInż no. 2 vehicle (with C7P gearbox) and this tank was to be made into series production.. 

The evaluation of vehicles from the PZInż and single one from the BBTech Br. Panc were conducted in the  Puszcza Kampinoska (Kampinoska Forest).

 

21.08.1939 

The paper regarding tests and improvements made in the PZInż no. 2 vehicle (C7P gearbox) was made.

Adjustments:

- moving the periscope/sight 80 mm forward,

- window of gunner’s left-side turret periscope raised 80 mm,

- direction scale added to the commander’s observation periscope,

- more efficient turret rotation drive was introduced (as the turret was heavier),

- studies regarding the improvements of ammunition were outlined,

- the lack of possibility of adding driver’s machine gun due to the mantlet was stated,

 

August/October

After capturing Warsaw, both prototypes were probably taken by Germans or hidden/destroyed by the Ursus employees.

According to the photographies, at least part of the PZInż prototypes stayed in Ursus (vide known photos of the PZInż 130). It would explain why the Germans could capture two vehicles. 

Was the third prototype (BBTech) evacuated?

 

 

Some sources state that 11 so called 9TP tanks did take part in fights - defending Warsaw, that's no true...

As was already cleared... there are photos clearly showing taht at least part of PZInż prototypes have remained in Ursus, being captured there by Germans.

 

Fate of these machines remains uncertain till present day. The prototypes were either captured by Germans after taking Warsaw or destroyed by Ursus’ workers.

Third prototype 7TP (reference, build from unfinished C7P of last production bath) was evacuated and probably cannibalised for field repairs of other vehicle's. 

There are no sources that could unequivocally confirm accounts of 11 9TP tanks having been produced and used during defense of Warsaw.

 

People claiming that 7TP reinforced and / or 7TP wz.39 were used in combat are often referring to the following publications:

 

- A. Jońca, J. Szubański, R. Tarczyński: Wrzesień 1939. Pojazdy Wojska Polskiego. Barwa i broń., Warszawa: Wydawnictwa Komunikacji i Łączności, 1990, str. 32, 52-58,

- A. Wszendyrówny, M. Wodejko: Czołg 7TP w dokumentach Centralnego Archiwum Wojskowego, w: "Do Broni", nr 1/2009, s. 96.

 

The following statements might be found there: 

2nd Light Tank Company of Warsaw Defence Command (...) Equipment: 11 7TP tanks (from PZInż current production) (p.32)

In September, about a dozen (11?) 7TPs rolled out of factory’s current production. (p.52)

The prototype (...) was constructed in 1938 and at the beginning of 1939 tests were ended. As the consequence, contracts for delivery of new armor plates were signed. Therefore, it is reasonable to suspect, that the tanks delivered for the army in 1939 had new armour scheme.

 

As we can see, instead of explicit confirmation, only suspicions are found, and 11 tanks mentioned in excerpts above were probably part of last 7TP production series based on C7P tractors.

 

 

7TP reinforced, BBT Br Panc factory prototype, shown at 20.04.1939

- welded armor with thickness in range 8-30 mm, evenly laid, mass similar to the series 7TP, about 9858 kg with the service, sides of the vehicle made from two plates,

- original 7TP suspension,

- the difference of axial loading limited to 68 kg from 785 kg in standard 7TP,

- ultimately carburetor engine (powered by petrol) PZINż 725 with power of  95-100 HP (maximal about 105 HP), weight 370 kg, requires single radiator. Standard Saurer VBLDb weighted 850 kg and required two radiators. The engine was located near the side of the hull, behind the driver. The engine was not series produced yet,

- the Cardan shaft (without joints) was altered and moved to the side of the vehicle, eliminating the obstacle that hindered the ability of crew to work inside of the tanks,

- standard gearbox (aluminum casing),

- 130 mm (to 1988 mm) lower profile of the tank due to smaller engine, 

- favorable silhouette (skewed frontal plate, different rear etc.),

- more space inside, increased crew comfort,

- two wz. 34 periscopes for driver and commander,

- thicker rubber layer on the road wheels,

- intended speed of 32-34 km/h (on road?),

- removal of all air circulation shutters, introducing solution as in  „Skoda”/”Koblen Danek” tanks.

 

 

 

7TP wz.39, prototype made by PZInż (E. Habich) shown at 05.04.1939.

Features:

Welded lower armor plate with thickness of 5 to 40 mm., uneven thickness: 40 mm in front, 25, 20 and 13 mm on sides, 40 mm turret front, 20mm turret back and sides, rear and upper armor without changes in relation to initial design of 7TP tank, 

- PZInż 155/CT1D engine — license model produced by PZInż since early 1938.

- Gearbox adopted from C7P tractor (aluminium casing),

- Increase in weight to ca. 11 tons (different sources claim increase of 729 or 800 kgs compared to standard version).

- Reworked suspension, track width 320 mm (standard version — 267 mm)

- Slightly changed outline (three additional plates of side armor?)

- Road wheels covered with rubber,

- substantially increased pressure of front wheels.

- Increased mass may result in engine overheating issues (radiators in standard version were working at maximal power).

- Speed up to 26,6 km/h on the road and 11,5 km/h off-road (tested in Kampinos village).

Unfortunately due to the fact, that in the game so far there are no two-piece weapon systems , "Hibernyt" is quite controversial.

You can keep the 7TP reinforced (the prototype by BBTBrPanc), although there are no photos of build prototypes.

Survived only comparative sketches and some technical documentation of both prototypes, with some "artistic creativity" those could be enough to create reliable reconstruction and game models.

 

However as those were only two purposefully build prototypes and third comparison vehicle build from non finished C7P tractor, those can be consider only as candidate for a premium vehicle.

 

 

 

9TP - an unofficial name for the improved 7TP tank , ordered by the Polish Ministry of National Defense in 29th June 1939 and planned to be produced since autumn 1939.

 

It is also known as  7TP wzmocniony (7-tonne Polish, reinforced) and  7TP wz. 1939 (7-tonne, Polish, mod. 1939) , after the names of two prototypes.

Certain non reliable sources claim that 7TP wz. 1939 version entered mass production in September 1939.

 

Protracted designing-construction works of Polish tank prototypes and the lack of ability to furnish army with modern equipment from abroad gave the foundation for a huge 7TP development in 1938. This programme was mainly aimed at increasing tank’s military value throughout strengthening its armour and (due to envisaged weight increase) using much more reliable powertrain which was supposed to maintain good manoeuvrability and traction performance. In the mid-1930’s, a large experience had been collected, and significant achievements in the field of producing armour plates were reported. Employees of Laboratorium Mechaniczno-Chemiczne BBT Br. Panc. (Mechanical-Chemical Laboratory of Armoured Weapons Technical Research Bureau) in cooperation with Komisja Badania Blach i Płyt Pancernych Instytutu Metalurgii i Metaloznawstwa (Commission for Research of Armour Plates and Sheet Metals from the Institute of Metallurgy and Metal Science) and metallurgical industry representatives had carried a lot of arduous studies followed by endurance tests of homogeneous and cemented (case-hardened) armour. Owing to the fact that Polish industry had short tradition in manufacturing modern plates, such issue was considered as a top priority. These researches led to work out and master mass production of 3-50 mm thick homogeneous armour plates, and also 8-20 mm thick cemented ones.

 

What was crucial for tanks’ mass production was that metallurgical achievements had made it possible to devise new methods of welding such huge components as hull. In 1937, on the basis of tests results, Maj. Eng. Tadeusz Biemacki, the manager of metallurgy department in Labolatorium BBT Br. Panc., designed and accomplished 7TP’s experimental hull, made of 5-17 mm thick welded armour plates. It weighted around 1700 kilograms — significantly less than hulls built with the previous method, i.e. through superposing plates on a grit formed frame, and, later on, merging them by rivets or screws.

 

Furthermore, some steps forward in the field of combustion engines had been made. In 1936, the engineers from BS PzInż (Studies Bureau of the State Engineering Works) — Jan Werner, Jerzy Dowkontt, Wacław Cywiński — created prototype power plants of own design, including the PzInż. 705 carburetor engine (indicated for a new family of lorries), and its derivative modification: the PzInż. 725 (more powerful, designed for heavy goods tracked vehicles). Data sheet of PzInż. 725: 345 kg, 6-cylinder inline vertical, cylinder bore x stroke: 100 x 110 mm, capacity: 5180 cm³, 95 HP at 2800 rpm, compression ratio: 6.35.

 

By 1939, several prototypes of this engine had been built; although they were factory-tested, it was impossible to gain some experience from long term exploitation. Accordingly, at the beginning of 1938, the State Engineering Works received the brand new Saurer CT1D diesel engine, and its bulk production was about to be launched under the designation PzInż. 155. Data sheet of PzInż. 155: 600 kg, 6-cylinder inline vertical, cylinder bore x stroke: 100 x 110 mm, capacity: 7980 cm³, 100 HP at 1800 rpm, compression ratio: 16. The Saurer Company provided complete documentation and several model engines.  The production start-up was foreseen for 1939.

 

In April 1938, the Armoured Weapons Command ordered in the State Engineering Works a prototype 7TP tank with such power plant. One month later, it was finally built and delivered to Armoured Weapons Technical Research Bureau (the sample was probably made of iron plate).  The tested vehicle (loaded with extra weight in order to simulate heavier armour) was considered as better than the one with PzInż. 725 engine. Its only disadvantage was that the newer motor showed less abilities to overcome rough terrain capabilities, which were caused by weight increase, while keeping the same chassis.

 

The proposals for further 7TP modernization were presented in two projects:                                                            

– the first, proposed by Armoured Weapons Technical Research Bureau (7TP reinforced): this modification provided newly developed Polish PzInż. 725 petrol engine (95 HP), which was smaller than the diesel one, and welded hull, of a lower profile, with a slanted front plate of the combat compartment. The brand new power plant was mounted on a right side of engine compartment (a drive shaft was also moved to right side, so it would be less an obstacle for the turret's crew). What is more, the cooling system had been significantly changed: its cooling grates were removed from an engine deck, and replaced with slots in sides. The motor's mass had an influence on reducing overall tank weight. All these qualities weighted in favour of PzInż. 725. On the other hand, the use of petrol increased the risk of fire, and tank would be ignited by direct hit. The armour, while maintaining the 7TP's weight and traction performance, was to be up to 30 mm in front and rear (vertical plates), 25 mm on a front slanted plate and the driver's hatch, and 20 mm on sides and turret. The driver was to be equipped with two G wz. 34 reversible periscopes. 

 

– the second, proposed by Studies Bureau of the State Engineering Works, worked by Edward Habich (7TP mod. 1939): in this variant, the PzInż. 155 engine was used. The tank hull shape was slightly different, in comparison with the 7TP; only armour thickness increased from 17 mm to 40 mm in hull front, from 17, 13 and 9 mm to 25, 20 and 13 mm respectively in sides, and from 15 to 20 mm in turret's sides and to 40 mm in turret's front. Weight also increased to 10 594 kg, so strengthened suspension (320 mm wider tracks, road wheels with replaceable rubber), and C7P tractor's transmission were proposed.

 

Both project were submitted for consideration in May 1939. Despite the fact that the State Engineering Works draw heavy criticism from Col.

- ultimately carburetor engine (powered by petrol) PZINż 725 with power of  95-100 HP (maximal about 105 HP), weight 370 kg, requires single radiator. Standard Saurer VBLDb weighted 850 kg and required two radiators. The engine was located near the side of the hull, behind the driver. The engine was not series produced yet,

- the Cardan shaft (without joints) was altered and moved to the side of the vehicle, eliminating the obstacle that hindered the ability of crew to work inside of the tanks,

- standard gearbox (aluminum casing),

- 130 mm (to 1988 mm) lower profile of the tank due to smaller engine, 

- favorable silhouette (skewed frontal plate, different rear etc.),

- more space inside, increased crew comfort,

- two wz. 34 periscopes for driver and commander,

- thicker rubber layer on the road wheels,

- intended speed of 32-34 km/h (on road?),

- removal of all air circulation shutters, introducing solution as in  „Skoda”/”Koblen Danek” tanks.

 

 

 

7TP wz.39, prototype made by PZInż (E. Habich) shown at 05.04.1939.

Features:

Welded lower armor plate with thickness of 5 to 40 mm., uneven thickness: 40 mm in front, 25, 20 and 13 mm on sides, 40 mm turret front, 20mm turret back and sides, rear and upper armor without changes in relation to initial design of 7TP tank, 

- PZInż 155/CT1D engine — license model produced by PZInż since early 1938.

- Gearbox adopted from C7P tractor (aluminium casing),

- Increase in weight to ca. 11 tons (different sources claim increase of 729 or 800 kgs compared to standard version).

- Reworked suspension, track width 320 mm (standard version — 267 mm)

- Slightly changed outline (three additional plates of side armor?)

- Road wheels covered with rubber,

- substantially increased pressure of front wheels.

- Increased mass may result in engine overheating issues (radiators in standard version were working at maximal power).

- Speed up to 26,6 km/h on the road and 11,5 km/h off-road (tested in Kampinos village).

So I made some small updates to some vehicles such as a new video of the AMZ Kutna Bóbr-3 Tank Destroyer. Unfortunately I'm currently capped on picture upload space so I can't add anymore information/pictures/data to the tree, however, if anyone posts the full data for WIP vehicles in the comments, I'll reflect it in the tech tree and state the originator of the information. Thank you! 

 

I want to add there is not many options currently in-game for a Polish sub-tree or a country to add it to. The only other ways is for the tree to be part of something like a future Visegrád/Eastern European tree, a part of the French Tree, German Tree, or preferably its own stand-alone tree. Some of those options are least to be desired however, I stand firm on adding a full/complete Polish Tech Tree above all options. Please use this information from this Tech Tree to support a full/complete Polish Tech Tree. 

 

I will also be reflecting the 7TP Reinforced in the Tech Tree, thanks for the information @RazNaRok!

Considering that Israel now got their own tree It's safe to say that most suggestions like this are defunct as there where many nations which have far more domestic designs that weren't added. Poland Czechoslovakia and Yugoslavia all being prime examples. They should be added as their own trees.

Polish sub-tree, It's a +1 for me.
