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.
A personally constructed (D.I.Y) 37mm launcher may be made at home (see list of 3D printed weapons and parts or homemade firearm for more information), and does not need to be registered as a firearm or a destructive device, as is the case for factory-made launcher devices. Likewise, you cannot possess or use 37mm anti-personnel ammunition or ...
The 37mm HE round had 39 grams (0.085 lb) of TNT, producing an explosive power of 161 Kilojoules. [ 26 ] [ 27 ] By way of contrast, the HE round from a Sherman 75mm gun had 667 grams (1.47 lb) of TNT, producing 2790 Kilojoules, while the modern 40mm shell from M203 grenade launchers has 32 grams (0.07 lb) of Comp B, producing an explosive power ...
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 SockelFlak was a gas-operated automatic cannon which fired a 37 mm (1.5 in) steel base fused explosive round with two brass driving bands. [4] The gun was mounted on a light three-legged pedestal mount with a seat for the gunner and could be broken down into four loads for short-range transport or carried in one piece on a cart by a two ...
Armour piercing discarding sabot munitions were developed to increase penetrating performance of anti-tank projectiles by generating higher impact velocity.A larger projectile would require a completely new weapon system, but increasing velocity faced the limitation that steel armour-piercing (AP) projectiles shattered at velocities above about 850 m/s when uncapped.
The magazine holds 30 rounds. [55] [57] [58] The initial prototype was created using an Objet Connex26 using VeroClear printing material (a transparent material) in order to show the magazine's round count and feeding action. [59] It was able to handle enough stress to fire 342 rounds and can fire 227+ rounds in quick succession. [58]
The 37 mm M9 autocannon was a derivative of the M1A2 anti-aircraft gun. It had a 74 in (1.9 m) barrel, weighed 405 lb (184 kg) (the barrel alone weighing 120 pounds), had a muzzle velocity of 3,000 ft/s (910 m/s), and had a rate of fire of 150 rounds per minute.
