The Royal Small Arms Factory ADEN cannon (ADEN being an acronym for "Armament Development, Enfield")[4] is a 30 mm revolver cannon used on many military aircraft, particularly those of the British Royal Air Force and Fleet Air Arm.[5] Developed post-World War II primarily to meet British Air Ministry's requirement for increased lethality in aircraft armament, the cannon was fired electrically and is fully automatic once it is loaded.[6]
