The AN-22 was France's second air-dropped nuclear weapon, developed as a replacement for the earlier AN-11 bomb, entering service in 1967.

It had a similar 60 to 70 kilotons yield fission warhead to the earlier AN-11, but with enhanced safety features and a parachute retarder to enable it to be dropped at low level.

A stockpile of about 40 weapons was maintained, providing one for each of the 36 Mirage IVAs in service, plus several spares.

The last warhead was retired on 1 July 1988, at which point the ASMP standoff missile took over the role previously held by the AN-22.
