fighter F-7 BGI

[Miraz05 255]

Brief History:J7 BGI is an upgraded variant of J 7 BG.It was bought as a stop gap solution for BAF until a modern single engine fighter jet comes in service of BAF.It was modified to meet the needs of Bangladesh Airforce.It is operated by ThunderCat squadron of BAF.It is primarily intended for interception but currently it plays more of a ground attacking role.J/F 7 BGI is the most modern version of j7.J7 BGI is also the last production variant of J7.The last fighter was delivered on 2013.Nato code name:Fishcan.

Specifications:

Cockpit: 2 new MFDs were added and it also received a HOTAS.It also received a new HUD.Helmet mounted sight and night vision equipments were also added.The plane uses Martin Baker Mk.10 ejection seat(https://martin-baker.com/news_events_post/martin-baker-constructs-new-bangladeshi-centre-of-excellence-for-aircrew-safety/).

Note:Most sites including various local news sites claim(Claim is based on a speech of Air chief Marshall.He said that this plane has 3 large MFDs.) that this plane has 3 MFDs but only 2 MFDs can be seen in most picture.So either those pictures are from F-7BG(BG version uses 2 MFDs) or maybe F-7 BGI doesnt have 3 MFDs.F-7 BG is an export variant of J-7 G.

 

Radar:KLJ-6F Pulse Doppler Radar,Range:86 Km+ and it has TWS and BVR mode.It can track 6 targets while locking on 2 targets but it’s only claimed by unofficial sources.The radar provides lead indicator for the pilot and it can slave IR missiles.On some forums i saw that this radar is a copy of EL/M-2032,im not sure whether if it’s true or not.(Im sure that KLJ-6F radar is used in this plane because in a recent victory day parade the narrator said the plane has "Modern Pulse Doppler Radar") (https://www.key.aero/forum/modern-military-aviation/73121-continued-utility-of-the-modernized-f-7-series,https://www.sinodefenceforum.com/t/the-q-5-j-7-j-8-and-older-plaaf-aircraft.4280/page-2,https://www.globalsecurity.org/military/world/bangladesh/air-force-modernization.htm,)

Instruments:Probably most instruments are same as F-7 BG.A new HUD (made by the Xian Sicong Group) in the F-7BG provides pilot with displays for instrument flying, with air-to-air and air-to-ground weapon aiming symbols integrated with flight-instrument symbology. It can store 32 weapon parameter functions, allowing for both current and future weapon variants. In air-to-air combat its four modes (missiles, conventional gunnery, snapshoot gunnery, dogfight) and standby aiming reticule allow for all eventualities. VCR and infrared cockpit lighting on the F-7BG is to be used with a Chinese (Cigong Group) Helmet Mounted Sight (HMS) slaved to the PL-9 AAM. The new air data computer coupled with the new HUD in the air-to-ground mode is capable of projecting both Constantly Computed Impact Points (CCIP) and Constantly Computed Release Points (CCRP) - which will use internal GPS and INS.

Defensive equipments: Most equipments are probaby same as F-7BG or they might have been upgraded.F-7BG's self defense equipments: South-West China Research Institute of Electronic Equipment KG-8602 RWR interfaced with the South-West China Research Institute of Electronic Equipment KG-8605 internal radar noise jammer and China National Import and Export Corporation GT-1 chaff/flare dispenser, and Type 602 'Odd Rods' IFF.

The F-7BG also comes with SE-2 Airborne Missile Approach Warning (MAW) Sensors located at the rear and port and starboard sides.(http://www.globalmil.com/military/air_force/china/systems/ew_ecm_elint/2010/0331/192.html)

Note:These things are probably changed in the BGI version or maybe it’s unchanged.Since BGI version is nearly identical to BG version apart from a different radar and some instruments and because of that reason we can assume that it’s defensive equipments are also same as the BG version.

 

Airframe:The airframe is most likely inherited from F-7BG.It has double delta wings.

Fuel Capacity:4165 Kg(It’s for F-7BG but I think it's probably same for F-7BGI,since BGI version is based on BG version)

G-Limit:+8/-3

Climb Rate:195 m/s

Service Ceiling:17500 m(Approximately)

HardPoints:The aircraft has 5 hard points to carry air to air missile,laser guided bombs,GBUs and drop tanks for additional fuel.It can carry up to 3000 kgs of suspended armaments.Most of the time only 3 of the hardpoints are used because other 2 hard points are most of the times occupied by drop tanks but during interception missions the plane usually carrys 4 aams.

Gun:2×Type 30-1 or maybe 1×Type 30-1(I dont know if it has 2 or 1 gun but in the pictures it looked like it had only 1 gun)

Suspended Armaments:

AAMs:

• PL-5EII(https://en.wikipedia.org/wiki/PL-5)(Proof:Tender)
• PL-7(https://www.militaryperiscope.com/weapons/missilesrocketsbombs/anti-air/pl-7-air-air-missile)(Proof:Old video)
• PL-9C(https://www.deagel.com/Defensive Weapons/PL-9/a002626,(proof:HUD view)

Rockets and Bombs:

• 90mm,57mm unguided rockets
• TYPE-200A bomb(Proof: Procurements.) 
• 250-3 Anti tank Bomb(Proof:Tender) 
• LS-6
• TEBER guidance kit Mk 81,Mk 82
• 500kg and 250(FAB-250/Mk 81) kg bombs

Spoiler

Type 200A bomb at Bangabandhu

Military Museum (Tender is declassified.)

It can also use an unknown 3000kg bomb(In a recent victory day parade,the F-7 was doing its aerobatics where the announcer said that the plane can carry a 3000kg bomb for ground attacking role),

.LS-6 uses the plane's internal GPS and INS system for guidance. (http://chinesemilitaryreview.blogspot.com/2012/11/chinese-ls-6-satellite-ins-thunder.html,http://www.ausairpower.net/APA-PLA-GBU.html#mozTocId132067,http://www.taipeitimes.com/News/taiwan/archives/2012/01/03/2003522296)

Also Some sources have mentioned that it can carry SD-10 Air to Air missile.[Note:the plane should be capable of carrying BVR missiles such as PL-12(SD-10) but it should not be in the game since Bangladesh didn't buy any BVR missiles for J 7 BGI. If the devs want they can add this missile for balancing purpose]

 

Typical AAM loadout:

• 4×PL 5EII
• 4×PL 9C

Occasionally PL-7s are used.I have only seen PL-7s being used once in a very old training video.Its better to exclude PL-7s for this jet.

 

(This is loadout is mentioned by a Narrator during victory day parade 2017,so there is no way this loadout is false.Im not sure about PL 8 loadout,the narrator said nothing about PL 8 so Wikipedia might be wrong)

Completed tenders are considered declassified.This was taken from a publicly available source.

 

Recent Upgrades:Recently the plane got a few upgrades.One of the upgrade includes TEBER guidence kit which is made by Turkey’s Rocketsan.Which allows the plane to carry Mk 81 and Mk 82 laser guided bombs.The plane didnt receive any new guidance pod since the plane already had guidance system integrated.Older guidance system might have been modified to work with Mk. 81 and Mk. 82 bombs.The work has only began recently that's why images aren’t available. (https://www.roketsan.com.tr/en/products/teber-guidance-kit)

 

Engine:It uses a improved version of WP-13F engine.WP-13F1 I think. The engine can produce 82Kn of thrust but some say it can only produce 62Kn of thrust. Max speed Mach 2.2. WP-13F1 is also known as WP-14C.Proof that this plane uses this engine:

Completed procurement are considered declassified.This was taken from a publicly available source.

Last two engines are probably meant for F-7BGI. I guess it uses WP-13F1 engine.

 

NOTE:BGI's 'I' is actually 1.Its not a alphabet rather its a number.

After reviewing your suggestion, I will have to currently deny it however changes can be made for me to re-review it.
1. polls 2 and 3 require a negative/no or I said no option.
2. If Bangladesh never fitted PL-12's you don't need to include it in your suggestion. 

You will have 48 hours to make any changes you want to the post after which I will re-review it and if no changes or the changes made are not enough I will be archiving it.
If you have any questions or concerns feel free to ask.

oh,thanks

I couldnt get any accurate information about its engine.In some pdf of overhauling tender I saw that F-7BG and F-7 BGI both uses WP-13F but in other documents only BG is written there.Also WP-13F probably cant produce 82 kN of thurst which is claimed by most sources.Here are some screenshots of those docs(Btw these documents arent classified or secret).In this screenshot we can see that F-7 BG and F-7 BGI(BG1) both are mentioned.

Bangladesh Sub tree might bring some more variety in chinese tree.Then the Top tier would get Jets such as Mig 29,F-7 BG,F-7BGI and maybe F-16V or Eurofighter in the future.But the Sub tree would lack proper rank 1-3 fighters.Only planes that can be added at that rank is PT-6 which isnt a actual fighter.

Some people might not like the idea of having more western stuff in chinese tree.

[NestleKitkat 1,404]

+1 but, I'd rather have stuff from Pakistan than from Bangladesh because Pakistani J-7s could carry AIM-9Ls that is one of best IR missiles in the game.

 

However, If Gaijin implemented 1990s and 2000s IR missiles and advanced ARH missiles then, go a head.

PL-9C is much better than AIM 9L.PL-9C is all aspect 40G missile with 22km range.

I understand your point.Pakistani Sub tree would be a much better idea than adding a Bangladesh sub tree.

Some Bangladesh vehicle can be good special vehicle, while Pakistani is a better sub tree.

However, is it possible to create Pakistani sub tree?

I mean they has some Chinese aircrafts like F-6s and J-10, also FC-1 but, Those aircraft such as F-16A, Mirage III, CL-13B, etc. are still copy and paste from NATO.

Create air tree is harder than ground tree, you know, the development of aviation industry is slow.

And in my opinion, we don't need a Pakistan air sub tree, it can be instead by adding JF-17 in the tt and adding other vehicles as event/premium vehicle like the TAM/TAM 2Ip/TAM2C.

Only unique vehicle is better than add many westen copy.

K-8 and JF-17 would be a nice addition to the techtree

China has its own K-8, so JF-17 is the main and it is very suitable for this year's Gen4 update.

Many different versions of Pakistan Q5/J6/J7 can be special vehicles.

It lacks a targeting pod I think,there's no picture of it.LS-6 can use both gps and laser guidance.So I think in this case GPS guidance is probably used or maybe some thing like a drone designates the target.

This plane received some upgrades recently including a new Turkish origin guidance system for Rocketsan's Mk.82 and Mk.81 LGBs.This new upgrade may include a targeting pod.https://www.turkishdefencenews.com/bangladesh-supplies-teber-guidance-kit-from-turkiye/
