The AAI In-Line was a prototype aircraft machine gun developed by AAI Corporation. The weapon was intended for potential aircraft use and capable of high rate of fire similar to the M134 Minigun but with the accuracy of a fixed barrel machine gun. The In-Line machine gun concept worked and passed air force tests but was not further developed. Around three of them were manufactured. The only known example is on display at the Air Force Armament Museum.

Design

The AAI In-Line is an externally driven chain/crankshaft operated machine gun with six fixed barrels. The belt feed is unusual as it uses a synchronizer for every sixth round is to be chambered in each barrel. It is chambered in 7.62×51mm NATO.

M2 Browning Type of heavy machine gun

The M2 machine gun or Browning .50 caliber machine gun is a heavy machine gun designed toward the end of World War I by John Browning. Its design is similar to Browning's earlier M1919 Browning machine gun, which was chambered for the .30-06 cartridge. The M2 uses the much larger and much more powerful .50 BMG cartridge, which was developed alongside and takes its name from the gun itself. It has been referred to as "Ma Deuce", in reference to its M2 nomenclature. The design has had many specific designations; the official US military designation for the current infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly armored vehicles and boats, light fortifications, and low-flying aircraft.

Armed helicopter

An armed helicopter is a military helicopter equipped with aircraft ordnance. Most commonly, it is used for attacking targets on the ground. Such a helicopter could be either purposely designed for a ground-attack mission—in which case it would be more specifically categorized as an attack helicopter—or may have been previously designed for other uses, such as utility, air cargo, aerial reconnaissance, etc., with the weapons mounts being modifications, rather than part of the design of the helicopter. The purpose of the modification to an armed helicopter configuration can be field expediency during combat, the lack of military funding to develop or purchase attack helicopters, or the need to maintain the helicopter for missions that do not require the weapons.

The Afanasev A-12.7 is a heavy machine gun developed by Nikolay M. Afanasev in 1949 and adopted for service in 1953. This gun was supposed to have a considerably higher rate of fire than its predecessor, the Berezin UB aircraft machine gun. Due to excessive barrel wear however, it was eventually limited by an electrical trigger to a rate comparable to the Berezin UB. Initially intended to be mounted in the defensive turrets of the Tu-4 bomber, the A-12.7 was ultimately installed only in trainer aircraft and helicopters. Nevertheless, it was produced for 30 years.

The Fokker-Leimberger was an externally powered, 12-barrel rifle-caliber rotary gun developed in Germany during the First World War. The action of the Fokker-Leimberger differed from that of a Gatling in that it employed a rotary split-breech design, also known as a "nutcracker".
