The 37 mm M9 autocannon was a derivative of the 37 mm M1A2 flak gun and used the longer, more powerful 37×223mmSR cartridge. Compared to the M4, the M9 had 50% more muzzle velocity (3,000 fps) from a 78-inch barrel (vs. 65-inch in M4), and was twice as heavy (120 vs. 55 pounds for the barrel alone); the whole M9 weighed 405 pounds vs. 213 of ...
37 mm flare or "1.5 inch" caliber is the specification for a common launching system for non-lethal and less-lethal ammunition. Such launchers are also often known as "gas guns" due to their original use by police for launching tear gas projectiles.
37 mm gun or 3.7 cm gun can refer to several weapons or weapons systems. The "37 mm" refers to the inside diameter of the barrel of the gun, and therefore the diameter of the projectile it fires. However, the overall size and power of the gun itself can vary greatly between different weapons, in spite of them all being called "37 mm" guns.
As such, ammunition is typically fed from a belt system to reduce reloading pauses or for a faster rate of fire, but magazines remain an option. Common types of ammunition, among a wide variety, include HEIAP, HEDP and more specialised armour-piercing (AP) munitions, mainly composite rigid and discarding sabot rounds.
This could fire the same ammunition as the Bofors 40 mm anti-aircraft gun, and also had a version of Stielgranate ammunition made for it. 37 mm anti-tank gun M1930 (1-K) – This was a Soviet anti-tank gun designed by Rheinmetall and produced under license, which was very similar to the Pak 35/36, but lacking some improvements.
The 37×145mmR was a series of rimmed-case, fixed-ammunition cannon shells for use in the 37mm Browning M4 autocannon.. The rapid strides in aircraft protection made it necessary to develop an aircraft weapon that would fire projectiles with greater explosive and armor-piercing qualities than smaller caliber weapons.

The Type 94 37-mm AT gun was introduced in 1936. The design originated as an improvement to the Type 11 37 mm infantry gun, which was also used as a primitive anti-tank weapon. [5] However, its short bore, low muzzle velocity, short range and slow reloading time gave it a limited capacity against enemy armor. Development of a replacement began ...
