The DEFA 550 series was the standard cannon armament of all gun-armed French fighters from 1954 until the advent of the Dassault Rafale in the 1980s. A pair of these weapons, with 125–135 rounds per gun, is standard fit on the Brazilian ground-attack aircraft AMX International, the French Dassault MD 450 Ouragan, Dassault Mystere, Mirage III/V, Dassault Étendard and Dassault Super Étendard, Sud Aviation Vautour, Mirage F1, SEPECAT Jaguars, and the Mirage 2000 series. It was also used on the Israeli A-4E/F/H/N Skyhawk, IAI Nesher, IAI Kfir, and IAI Lavi, the Italian Fiat G.91Y and Aermacchi MB-326K, the Indonesian A-4, and the South African Atlas Cheetah and Impala Mk.II. Various gun pod installations are available from CASA, Dassault Aviation, and Matra.
