In World War I, aircraft were initially intended for aerial reconnaissance, however some pilots began to carry rifles in case they spotted enemy planes.Soon, planes were fitted with machine guns with a variety of mountings; initially the only guns were carried in the rear cockpit supplying defensive fire (this was employed by two-seat aircraft all through the war).
The Boeing YAL-1 airborne laser testbed was a modified Boeing 747-400F with a megawatt-class chemical oxygen iodine laser (COIL) mounted inside. It was primarily designed to test its feasibility as a missile defense system to destroy tactical ballistic missiles (TBMs) while in boost phase.
The gun is mounted slightly to the port side with the active firing cannon barrel on the starboard side at the 9 o'clock position and on the aircraft's center line. The front landing gear is positioned to the starboard side. [6] The gun is loaded using Syn-Tech's linked tube carrier GFU-8/E 30 mm Ammunition Loading Assembly cart.
During an attack, the gunship performs a pylon turn, flying in a large circle around the target, so is able to fire at it for far longer than in a conventional strafing attack. The AC-130H Spectre was armed with two 20 mm M61 Vulcan cannons, one L/60 Bofors 40 mm cannon, and M137 105 mm cannon and M37 recoil mechanism from the M102 howitzer ...
The B-25 bomber was heavily armed with 75 mm and .50 caliber machine guns.. During 1942 and 1943, the lack of a usable escort fighter for the United States Army Air Forces in the European Theatre of Operations led to experiments in dramatically increasing the armament of a standard Boeing B-17F Flying Fortress, and later a single Consolidated B-24D Liberator, to each have 14 to 16 Browning AN ...
When vehicle-mounted, the only limiting factor is the vehicle's safe carry weight, so commensurately larger ammo storage is available. Until the late 1980s, the M61 primarily used the M50 series of ammunition in various types, typically firing a 99-gram (3.5 oz) projectile at a muzzle velocity of about 1,030 metres per second (3,380 ft/s).
The M167 VADS consists of a 20mm M168 cannon, linked ammunition feed system, and a fire control system in powered turret, mounted on an M42A1 towed carriage. [ 1 ] The M167A2 VADS was modified with an improved fire-control subsystem.
The M163 VADS uses the M168 gun, a variant of the General Dynamics 20 mm (0.79 in) M61A1 rotary cannon, the standard cannon in most U.S. combat aircraft since the 1960s. The gun is mounted on a modified M113A1 vehicle (the M741 carrier). Designed to complement the M48 Chaparral missile system, it is limited to fair-weather operations. [3]
