With it's origins rooted in late Nazi German (Luftwaffe) Technology, The French DEFA Cannon was (and still is), a ''foundational'' armament platform weapon for many French Fighter Aircraft, since 1954. Although widely ''decomissioned'' in 1980, many variants still exist. The successful design was even adopted into the British version, or ADEN Gun (still in useage). The DEFA varint is also found inseveral anti-aircraft (ground) versions, used by both Naval and Infantry Support Units.
7-feet long (wing or fuselage mounted), The DEFA fires a standard NATO 30mm round ranging from 1,200 to 1,800 rpm. The ''chamber'' holds 5-round per shot, similar to many US ''Dragon'' or rapid fire guns found in use during The Vietnam War of the 1960s. The Class typically is rated to 2,000-yards (either air or ground fired).
