On 9 January 2019 a Dassault Mirage 2000D of the French Air Force disappeared from radar around noon local time, as it was flying over the Jura mountains close to the border between France and Switzerland. The prefecture launched a search and rescue operation, but heavy snow restricted visibility. The crash appears to be confirmed as the search party found first debris and a parachute near Mignovillard. The plane was based in Nancy-Ochey 133 Air Base, in the east of France. The base houses three fighter squadrons, all using Mirage 2000Ds.
The Mirage 2000 is a multirole fighter jet developed by Dassault Aviation in the 1970s. The D (Diversified) variant is an updated version of the airframe with two seats. Based on the Mirage 2000N (Nuclear), which was until 2018 the main nuclear strike platform of the French Air Force, the Mirage 2000D was designed for long-range precision strikes using conventional weapons. As for the nuclear role, it has since been taken over by the Rafale, another Dassault aircraft.
In an interview, the commander of the Nancy-Ochey 133 Air Base (BA133) Yann Burion declared that the two pilots on board were experienced and that this low altitude exercise was a routine mission. The Minister of Armies Florence Parly announced on the evening of 11 January 2019, that the pilot and the navigator on board the crashed Mirage 2000D were found dead. The circumstances of the incident have not yet been established.
