Aircraft/Loadouts Martin PBM Mariner

[SwissBaron 96]

The Martin PBM Mariner was a patrol bomber flying boat of World War 2 and the early Cold War period. It was designed to complement the Consolidated PBY Catalina in service. A total of 1,366 were built, with the first example flying on 18 February 1939 and the type entering service in September 1940. 

 

In 1937 the Glenn L. Martin Company designed a new twin-engines flying boat, the Model 162, to succeed its earlier Martin P3M and complement the PBY Catalina. It received an order for a single prototype XPBM-1 on 30 June 1937. This was followed by an initial production order for 21 PBM-1 aircraft on 28 December 1937.

 

The first PBM-1s entered service with Patrol Squadron Fifty-Five (VP-55) of the United States Navy on 1 September 1940. Prior to the outbreak of World War II, PBMs were used (together with PBYs) to carry ou t Neutrality Patrols in the Atlantic, including operations from Iceland. Following Japan's attack on Pearl Harbor, PBMs were used on anti-submarine patrols, sinking their first German U-boat, U-158 on 30 June 1942. PBMs were responsible, wholly or in part, for sinking a total of ten U-boats during World War II. PBMs were also heavily used in the Pacific War, operating from bases at Saipan, Okinawa, Iwo Jima and the South West Pacific.

 

The United States Coast Guard acquired 27 Martin PBM-3 aircraft during the first half of 1943. In late 1944, the service acquired 41 PBM-5 models and more were delivered in the latter half of 1945. Ten were still in service in 1955, although all were gone from the active Coast Guard inventory by 1958 (when the last example was released from CGAS San Diego and returned to the U.S. Navy). These flying boats became the backbone of the long-range aerial search and rescue efforts of the Coast Guard in the early post-war years until supplanted by the P5M Marlin and the HU-16 Albatross in the mid-1950s.

 

PBMs continued in service with the U.S. Navy following the end of World War II, flying long patrol missions during the Korean War. It continued in front line use until replaced by its direct development, the P5M Marlin, with the last USN squadron equipped with the PBM, Patrol Squadron Fifty (VP-50), retiring them in July 1956.

 

The British Royal Air Force acquired 32 Mariners, but they were not used operationally, with some returned to the United States Navy. A further 12 PBM-3Rs were transferred to the Royal Australian Air Force for transporting troops and cargo.

The plane could be in the research branch for the United States, as well as a British Premium plane. I feel War Thunder needs more bombers like this in the game to grow more attention to W.T. .

Thanks!

-PBM-3 (32 built)

  Wingspan: Same as PBM-1

  Length: 80 ft

  Height: Same as PBM-1

  Empty Weight: 32,328 lbs

Replacement of nose and dorsal turrets by powered variants. Waist gun "bubble" positions replaced with a bigger open position with armored hatches. Deliveries began in 1942. The type never saw active service and in the end all but one of these were converted to PBM-3R transports.

The RAF found the controls too heavy for long patrols and returned them, under the designation PBM-3B. ASV radar installed on most aircraft.

 

-PBM-3S (94 built)

  Wingspan: Same as PBM-1

  Length: Same as PBM-3

  Height: Same as PBM-1

  Top Speed: Same as PBM-1

  Range: 2,240 miles

Improved armor and engines. AN/APS-15 radar installed. First delivered in late 1943.

  Top Speed: Same as PBM-1

  Range: 2,700 miles

Engines replaced by more powerful Pratt Whitney R-2800s, cowlings redesigned to fit the change. Provisions for JATO/RATO added. Addition of windshield wipers. First delivered in August 1944. Some were modified into thePBM-5S configuration, similar to the PBM-3S. During the Korean War, the PBM-5S2 became the standard, which was a regular PBM-5 with the radar replaced by the AN/APS-31, placed in a "teardrop"-shaped radome.

 

-PBM-5a (36 built + 4 conversions)

  Crew: Same as PBM-3D

  Top Speed: Same as PBM-1

  Range: Same as PBM-5

Amphibious variant of the PBM-5. Modifications included nose wheel steering, reversing propellers (That enabled the plane to taxi backwards) and hydraulic boost for the control surfaces, decreasing the effort required to maneuver the large flying boat. The type never entered mass production or combat. Delivered from 1948 to 1949."

 

"(PrimeTheBomber) Apparently all PBM-3C's, D's and S's had the cooling fan in front of the engine. I found a couple pictures of it:"

 

 

"Also turns out the PBM-3C, PBM-3S and PBM-3D all had the 4-bladed Curtiss Electric propeller. And the PBM-5S-2 field modification removed the top turret".

Open for discussion.  :salute:

[mistomaxo 446]

a good number produced and a service life spanning the game's plane-timeline. its armaments seem rather similar to the pby's but it has a distinct appearance

 

its tailgunner looks much, much better positioned than the pbys

 

i hope it makes it, if not soon then perhaps someday after the introduction of naval forces, as seaplanes often worked in conjunction with them

I feel the PBM Mariner is a good alternative to the PBY, with it's different looks, etc. . I feel, especially when they add naval forces/more naval focused maps, the PBYs and Naval Fighters/bombers will become more popular. The PBM could fight side by side with the PBYs, etc.!

Why there's no option: "Useless, but would love to fly it"? :C

Not exactly useless.. other wise America wouldn't of built it. Anyways, added the pole option.

It was a lot more durable than the Catalina, and as far as I know off, had more fire power (would have a higher BR)! Can't tell my you wouldn't get hyped about that.

[SwissBaron 96]

But in WT?

Bombing, scouting (when they fix it) for realistic battles/historical battles, and when naval battles get more into it, torpedo-(ing?).

I'm a Catalina veteran here ;)

 

I won't expect, that Gaijin will fix sth important for gameplay. The game has got a crisis, and it's just a couting off coupons...

It's sad... But true.

[Stuka_Hunter 3,408]

Nope. I love Corsair, Fortress and Dauntless. P.S: I am not german. P.P.S: Dont judge by the picture I have on my profile. 

I can't believe a german planes fan said that.

What? Liking german planes doesnt make me a fan...

Anyway, back on topic. We dont need murrican plane spam in other tech trees. On that note, I wont support, but I wont say no either.

[Z3r0_ 4,128]

I guess this would be alright, but there's other more iconic aircraft from the war that are still missing from the tech tree that should get priority first (by those I'm mostly talking about P-38, P-40, P-47, P-51, B-24, and B-25 variants, as well as Corsair variants on the Navy tree, particularly the first production model F4U-1 and the F4U-4).

I would like to see it in game, but what tier would it be?

 

I'm guessing tier 2 because not very fast and 1800kg payload.

 

But then again 8 gunners....

Gaijin mostly has covered Germany and Japan, with their 9000 pro-types of BFs, FWs, zeros, etc. . America needs their key planes. Also, bite me.

They're already working on that stuff as far as I know of. It just takes time to publish them out.

I say the tier should be 2, but the BR about 2.3. It needs to be powerful, but not be shot down easily like the PBY.

I miss the games like Air Warrior 3, where you didn't grind and have a bunch of kiddies screaming for "P-38G3939239", just more versions of the same thing we have. We need to get some new planes in first. War Thunder needs these planes, and as well fix their spotting, etc. so it isn't FTP airplane C.O.D. .

[ItsCalledSoccer 96]

I definitely want it in game, +1

[PrimeTheBomber 259]

How would anyone call it useless? 4,000 lbs of bomb/depth charges/torpedoes, and bomb bay doors in the engines, plus 3 turrets with 2 .50 cals each. I for one, love this aircraft.

Let's be honest, the Germans were not known for beautiful aircraft. Even without the prototypes, they had some weird/ugly stuff, and some stuff you'd swear the designer was on drugs when he built.

[Pony51 6,572]

Already mentioned in another thread.

[Garfield_Pilot 1,596]

Excellent research.
Looks a lot like Short Sunderland to me.
It was deployed in numbers, has a payload and can defend it self. Enough for me to think it should be included.

I did not see your post before, and as far as I can tell, you just put "PBY-5a (but change to PBN or PBY-6a which is historical". That's all..
