German Starfighters were finally retired in the mid-1980s, being replaced by the Panavia Tornado and the F-4 Phantom, lingering on in specialized roles into the early 1990s. Many of the survivors were passed on to other air arms. Total losses were 270 aircraft, or about 30% of the force. Other air forces had higher loss rates, but the Luftwaffe was by far the biggest operator of the Starfighter and so had the highest absolute number of losses. After the F-104, the Germans would acquire a strong aversion to single-engine fighter aircraft.
I don’t know much about their use of the 104, but I have nothing but respect for the German army, their weapons were far superior to ours(small arms I mean)during the time I was stationed in Germany(1959 to 1960).
