At its peak in January 1970, the Luftwaffe fleet consisted of 310 G.91 R/3 and 40 G.91T aircraft. However, the Luftwaffe was always rather disappointed by the type's perfomance and so they were gradually replaced by the Dassault/Dornier Alpha Jet. The last G.91 aircraft was officially retired in 1982. This restored nose section is on display at the Luftfahrt- und Technik-Museumspark Merseburg.
