to the earlier AN-11, but with enhanced safety features and a parachute
retarder to enable it to be dropped at low level. Additionally the casing was redesigned reducing its weight from approximately 1,400 kg (3,000 lb) to around 700 kg (1,500 lb). It was carried by the Dassault Mirage IV

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
stand-off weapon took over the role previously held by the AN-22.

Nuclear weapon
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion. Both reactions release vast quantities of energy from relatively small amounts of matter. The first fission bomb test released the same amount...

AN-11 bomb
The AN-11 was France's first nuclear weapon, developed to arm the Force de frappe.The AN-11's development began in the late 1950s. An early version was used in France's first nuclear test, on 13 February 1960. The first AN-11 prototype was tested 1 May 1962, and it entered service in 1964.The AN-11...

Parachute
A parachute is a device used to slow the motion of an object through an atmosphere by creating drag, or in the case of ram-air parachutes, aerodynamic lift. Parachutes are usually made out of light, strong cloth, originally silk, now most commonly nylon...
