Aircraft artillery are artillery weapons with a calibre larger than 37 mm mounted on aircraft. First used for ground attack roles during World War I, aircraft artillery has found its use in the present day, most notably on the AC-130.
Aircraft artillery was first used for ground attack roles during World War I. A notable user of aircraft artillery was the fighter ace René Fonck. Airships were used with some success, mostly used to harass cities,[1] but after the development of incendiary ammunition they were stopped being used due to the fire igniting the hydrogen used for the Zepplins.
During World War 2 multiple planes used large calibre cannons for:
Destruction of armoured vehicles (Yak 9T[2] and Junkers Ju 87 G)
Destruction of small bunkers
Destruction of ships (P108 A[3] )
During the Cold War very high calibre cannons were being slowly replaced by Air to ground missiles and laser guided bombs. Current use of large calibre cannons found itself in gunships, (AC-130) due to the larger size more weaponry is able to be mounted.
