(WiP) List of US Built Interwar through World War 2 (1919-1945) Ground Vehicles, Possible Additions

Preface

Hello, I had originally made a list of US vehicles on the old forums. So, I’ve decided to redo said list on the new forums using a different format and style. Rather than just including all vehicles, even those that are already in game. This will only include those that could be added to the game. Also, it will be broken up into separate topics, Interwar-WW2(1919-1945), Cold War(1946-1979), and then Late Cold War - Modern (1980-Present). I’m also taking a bit of inspiration from @Stuhlfleisch 's posts on German vehicles.

for self propelled add the M7 priest, there were three variants made based off the M3 Lee chassis. the M7 of which there were 3489 built, the M7B1 826 built and the M7B2 which were converted M7B1’s which had the smallest at 127 considering this machines involvement throughout WW2 and into the korean war im surprised it hasn’t been added yet

It will definitely be added to this list thread. However, its likely when the suggestion section opens back up to new suggestions, those may need to be suggested again, unless they’d already been forwarded to the devs for consideration.

im bored out of my mind today expect me to be replying quite a bit so this is just the start, I really enjoy reading about WW2 especially the vehicles

just to to explain the M7B1 was based on the Sherman hull while the original M7’s were modified M3 hulls
theres also the T51 which are M7 priest modified to carry a 25pdr instead of the howitzer

Thanks for the info, I can probably look up through Hunnicutt’s or other books I have for pictures. Having a challenge finding a pic for the M4A1 Large Hatch 75 model… There were apparently 100 built, that were converted to DD versions.

DD are the amphibious correct?

also for the M2 light tanks their was apparently an AT variant made which removed the turret and added a 47mm autocannon but i cant find a picture

Medium tank T23E3. I hope the torsion bar version is added, just to be different from the T20. The T23 turret was eventually added to the M4 hull for the 76mm gun.

I’d love a T23 but I honestly don’t want one of the later suspension versions. They are heavier and it would just lead to similar mobility to the T25. Besides, the basic T23 has VVSS while the T20 has early HVSS, so you don’t even need to go into the T23E series to find a different suspension from the T20.

That aside… there’s also the whole issue where the T25 has a god awful garbage transmission, and if I’ve learnt anything, it’s that Gaijin will copy paste as much as possible even when they shouldn’t (the M6A2E1 and T1E1 both have modified M6A1 transmissions in-game).

On a side note, Hunnicut’s book on US WW2 medium tanks mentions an M4 with a reversible transmission.

From what I’ve managed to scrape together, it is one of the M4E6s, specifically serial number 30253, registration number 3038783, which alongside SN 30263 (another M4E6) was sent to Fort Knox and modified with early HVSS suspension and equipped with this new transmission, among other changes including increasing its final drive gear ratio to that of the M4A3E2.

A problem noted early in the career of the Sherman was its low speed in reverse. The gear ratio required for adequate hill climbing in reverse produced an agonizingly slow speed if the tank had to withdraw while under fire. In April 1943, the Ordnance Committee recommended the construction of six tanks with a reduced reverse gear ratio. However, the engineering tests revealed that although the reverse speed was increased, the climbing ability in that direction was unsatisfactory. The best solution was the installation of a planetary gear box which could reverse the entire transmission permitting operation at all five gear ratios. This gear box transmitted the power without any speed change in the forward direction. In reverse, the gear ratio was slightly increased. For example, if the maximum forward speed was 24 miles/hour, the reverse speed in the same gear was 21 miles/hour.
The high speed reverse transmission also included a new low level oiling system which reduced the oil capacity from 43 to 20 gallons. The operating temperature was greatly decreased and an additional 25 horsepower was transmitted to the sprockets. The new transmission used most of the parts from the standard unit and was completely interchangeable. Installation required the moving of the generator and electrical wiring. Also, the propeller shaft had to be shortened by 5 inches. The latter was an improvement since it reduced the shaft deflection and hence, bearing loads.
On 30 April 1944, OCM 23548 recommended the use of the high speed reverse and low level oil system but tests at Fort Knox were not complete until about a year later. In late 1944, the Armored Board received a 76mm gun M4 equipped with the new transmission. This vehicle, registration number 3038783, was one of the seven pilot tanks built at Detroit to serve as prototypes for the “Ultimate” Sherman. After tests, the Armored Board concluded that the high speed reverse transmission was far superior to the standard unit and recommended its adoption without delay for all tanks of the M4 series. Unfortunately, time had run out and the war was over before it could be introduced.
The M4 tested with the high speed reverse at Fort Knox also was fitted with final drives having a higher gear ratio of 3.36:1 compared to the standard 2.84:1. These were the final drives gears from the heavier assault tank M4A3E2. The Armored Board tests showed that although the speed on a level surface was reduced, the cross-country performance was greatly improved. Their report recommended this final drive ratio to be adopted for all production M4s, M4A1s and M32 tank recovery vehicles. The change was not recommended for the M4A3 because of its normal higher performance. Like the high speed reverse, hostilities ended before this feature was available.

This is a neat site that has more info on the “Ultimate Sherman” tests that were conducted.

Two-plane stabilizers, anti-HEAT composite side armor, concentric recoil system for the 76mm gun that allowed a coaxial .50 to be included in addition to the existing .30, some big-ass engines, and an infrared lamp/sight system for the driver.

Ups…

I think you posted in the wrong thread.

I’d like to see a researchable M8 Greyhound for the US tech tree, it makes no sense that such a ubiquitous vehicle should be a rare event reward.

I propose the M8 Greyhound (late), it differs from the earlier model M8 currently in-game because it has a turret ring for the M2 .50 cal.

  • T3: 1940, 1 prototype built

It should be noted that possible additions should be taken very liberally in this list. As already stated, some were unarmed albeit still had the turrets and mounts for the guns. This was done to some prototypes, such as the T11 armored cars and the 1932 version of the T2 medium, since it wasn’t considered to be necessary, whereas others never had them installed, albeit the holes for their installation were still there, because they were focused on testing mobility, such as the T2 light tanks and the experimental M1 combat cars and M2 light tanks.

In other cases, the performance of the gun is in question. I am not certain that the 37-mm M1916, utilized by a bulk of Christie’s tanks, would be usable in-game since it only has a base-fuzed high-explosive shell available to it for armor-piercing purposes. This was considered suitable during the 1920s and I guessed estimated that it would have somewhere between 20 mm to 25 mm of penetration based on the performance of the M63 in-game. However, if it’s lower, then it could very well be unusable. The only saving possibility is that they’re given the mle 1927 and 1936 APCR that the French developed for their S.A. mle 18 guns.

Another one of these cases are those of the T2 and T3 Brownings utilized by part of the T1 lights and as a hull gun on the T2 medium. I have no idea what their performance is and no one else seems to know either. They were considered suitable for anti-tank purposes – but, given that was in comparison to the 37-mm M1916, that isn’t very reassuring. The only hint to their performance is that the T2 fired a 37x123B cartridge at 2,000 fps and that the T3 fired a 37x120R cartridge at 1,350 fps.

Lastly – the 75-mm guns from this era had no armor-piercing capability. This was considered to be okay, since the concussive force alone was enough to crack the 0.6-inch armor of the M1917 light tank when the T1 medium tank tested its 75-mm M1920 against it. This, of course, wouldn’t be possible in-game since concussive force and armor degradation isn’t modeled. This was the same case for the 75-mm guns utilized by the T1 and the T3, though they had no intention to serve as anti-tank guns in those cases. They could be given the high-explosive anti-tank projectiles that were later introduced into their cartridges, but, at least in the case of the T1 medium, it would be quite weird to see.

Edit: Added the Mark VIII since it is, by a technicality, an interwar tank. The United States didn’t receive their first Mark VIII pilot vehicle until 1919, which was then refined into the American version of the Mark VIII which went into production the following year. It also had two modifications during its service, though they wouldn’t have a real difference between one another (aside from the pilot vehicle) if they were all added to the game.

I forgot, but Christie also developed several amphibious self-propelled guns during the early 1920s. This includes the:

  • Christie Amphibious M1921 or Amphibious Self-Propelled Gun, First Model; 1921, 1 prototype built; 1 x - 75-mm M1897 (12 mm penetration), 6.35/6.35/6.35 (H) mm armor @ 29.0 km/h (tracks) 29.0 km/h (wheels) 12.1 km/h (water) w/ 11.2 kW/t
  • Land and Water Motor Gun Carriage (Christie) for 75-mm Gun (LWMGC (Christie) 75-mm) (Christie Amphibious M1922) (Amphibious Self-Propelled Gun, Second Model); 1922, 1 prototype built; 1 x - 75-mm M1897 (12 mm penetration), 6.35/6.35/6.35 (0.25") (H) (T) mm armor @ 29.0 km/h (tracks) 29.0 km/h (wheels) 12.1 km/h (water) w/ 10.4 kW/t
  • Christie Amphibious M1923 or Amphibious Self-Propelled Gun, Third Model; 1923, 1 prototype built; 1 x - 75-mm M1897 (12 mm penetration), ??? (H) (T) mm armor @ ??? km/h w/ ??? kW/t
    • 1924; floatation devices and upper armor removed, sometimes referred to as the Christie Amphibious M1924
  • United States Marine Corps Tank, Gun Carrier 2 (U.S. Marine Corps Tank, G.C.2) (Christie Amphibious M1923); 1923, 1 prototype built; 1 x - 75-mm M1897 (12 mm penetration), 6.35/6.35/6.35 (H) (T) mm armor @ 29.0 km/h (tracks) 48.3 km/h (wheels) 12.1 km/h (water) w/ 9.5 kW/t
    • 1924; 75-mm M1897 replaced by a 37-mm M1916 (25(?) mm penetration)

However, the issue with them is the same as all of the other 75-mm gunned vehicles during this period: the United States did not have 75-mm armor-piercing projectiles. The first one wouldn’t be developed until 1939/40 when the M72 AP was introduced as a stopgap until the M61 APC, standardized in 1940, could begin production in 1942. Those are both well after these amphibious vehicles – and other tanks, like the T1E1 with the 75-mm and the T1 HMC, were scrapped.

I don’t know if the United States had any stock of French projectiles that they may have acquired during the First World War, where I imagine that there was at least some exchange, if not just the outright usage, of French stocks. If so, they may have acquired one of the numerous French armor-piercing projectiles that had been developed for the 75 x 350 mm R cartridge shared by the French mle 1897 and the American M1897. This would give the vehicles a penetration of anywhere between 68 mm (OP AL mle 1918) to 84 mm (OO mle 1898), depending on what projectile they receive.

That same solution doesn’t extend to the other vehicles, though. The 75-mm M1920 (T1 Medium), M1 (T1 HMC, T3 HMC), and M1A1 (T5E2 Medium) use the 75 x 272 mm R cartridge. The only armor-piercing projectile every developed for them was the M66 HEAT which wouldn’t be introduced until the middle part of the Second World War.
