On March 11th, 1959, the former West German Ministry of Defence signed a contract with Feyate Company to purchase 50 G.91R-3s and 20 G.91T-3s. During 1961 ~ 1966, about 295 G.9IR-3 attack aircraft and 22 G.91-3 trainer aircraft were produced in Donier, Heinckel and Messerschmitt. The first G.91R-3 aircraft made in Germany made its first flight on July 20th, 1961. The airframe of this aircraft is basically the same as that of R-1. The fixed weapon was replaced by two "Defa" 552 guns with 30mm caliber, and the combined navigation equipment of Doppler radar and TACAN was adopted. The US Air Force also purchased two aircraft of this type.
