The Dassault Mirage 2000 is a French multirole, single-engine, fourth-generation jet fighter manufactured by Dassault Aviation. It was designed in the late 1970s as a lightweight fighter to replace the Mirage III for the French Air Force (Armée de l'air). The Mirage 2000 evolved into a multirole aircraft with several variants developed, with sales to a number of nations. It was later developed into the Mirage 2000N and 2000D strike variants, the improved Mirage 2000-5, and several export variants. Over 600 aircraft were built and it has been in service with nine nations.
The Mirage 2000B is a two-seat operational conversion trainer variant which first flew on 11 October 1980. The French Air Force acquired 30 Mirage 2000Bs, and all three AdA fighter wings each obtained several of them for conversion training.
