History
It was developed in the USA in 1942 , during the Great Patriotic War it was supplied to the USSR under Lend-Lease . It was used in the Great Patriotic War , and after its end was in service with the Soviet Army until the adoption of anti-aircraft missile systems .
In 1944, the 90 mm semi-automatic M2 anti-aircraft gun, created on the basis of the 90 mm M1 gun , was adopted by World War II. A number of design changes made to the gun’s bed made the M2 2 tons lighter and easier to put into combat position. The effectiveness of anti-aircraft guns increased significantly when the shells with a radio fuse were adopted.
This is the latest semi-automatic anti-aircraft gun created in the United States. [1] The SCR-268 radar was used to aim the artillery battery, and the SCR-584 at the end of World War II .
Application
The device of the gun, M2, had the ability to lower the barrel below 0 °, which allowed it to be used for firing at ground moving and stationary targets, including armored vehicles . During the Korean War (1950-1953), the M2 was actively used in combat as ground support weapons [2] .
Mechanism
The shutter of the gun is semi-automatic, wedge-shaped.

M3
The 90-mm M3 semi-automatic rifled gun built on the basis of an anti-aircraft gun with a maximum muzzle energy of 3.97 MJ / 405 tf · m was the main armament of the M36 tank destroyer . The gun had a monoblock barrel with a length of 50 calibers / 4500 mm [sn 1] and a vertical wedge bolt . To balance and ensure smooth guidance in the vertical plane, the M3 was equipped with a spring- type compensator. The technical rate of fire of the gun was 8 rounds per minute [3] . Starting with the 601th self-propelled guns, the guns were equipped with a threaded mount for a single-chamber muzzle brake , however, up to the 1400th machine, they were not equipped with the M36 muzzle brake at the factory and were equipped with a protective casing for threaded mounting [4] . In the post-war period, a certain amount of M36 was overhauled by major upgraded guns of the M3A1 model [ overhaul 2] during overhaul. The main difference of this gun was the presence of an ejector to remove powder gases from the bore after the shot, for an open self-propelled gun, which, however, was almost useless [5] .
Notes
- ↑ According to the American system for measuring barrel length. It should be borne in mind that in different countries different measures were used to measure the passport “barrel length”, which may make direct comparison of this parameter with other guns impossible.
