The air-sol moyenne portée (ASMP; medium-range air to surface missile) is a French nuclear air-launched cruise missile manufactured by MBDA France. In French nuclear doctrine it is called a "pre-strategic" weapon, the last-resort "warning shot" prior to a full-scale employment of strategic nuclear weapons. The missile's construction was contracted to Aérospatiale's Tactical Missile Division, now part of MBDA. The cost of the missile development in 1988 was $600 million[1] or $1.37 billion in FY 2021.

ASMP entered service in May 1986. An improved version, the ASMP-A, was developed between 1997 and 2009.



ASMP entered service in May 1986, replacing the earlier free-fall AN-22 bomb on France's Dassault Mirage IV aircraft and the AN-52 bomb on Dassault Super Étendard. About 84 weapons are stockpiled. Carrier aircraft are the Dassault Mirage 2000N, Rafale and Super Étendard. The Mirage IVP carried the ASMP until retired in 1996.

ASMP and ASMP-A is 5.38 m long and weighs 860 kg. It is a supersonic standoff missile powered by a liquid fuel ramjet.[5] It flies at Mach 2 to Mach 3, with a range between 80 km and 300 km for the ASMP and 500 km for the ASMP-A depending on flight profile. The ASMP uses the TN 81 warhead, which has a variable-yield of 100 to 300 kilotons of TNT (420 to 1,260 TJ).

In 1991, 90 missiles and 80 warheads were reported to have been produced. By 2001, 60 were operational.[6]


An advanced version known as Air-Sol Moyenne Portée-Amélioré ASMP-A (improved ASMP) has a range of about 500 kilometres (310 mi)[7] at a speed of up to Mach 3 with the new TNA (Tête Nucléaire Aéroportée) 300kt thermonuclear warhead.[3] It entered service in October 2009 with the Mirage 2000NK3 of squadron EC 3/4 at Istres and in July 2010 with the Rafales of squadron EC 1/91 at Saint Dizier.[8] 54 ASMP-A have been delivered to French air force.[9]


The ASMPA-R (renovated) project, launched in 2016, will see the missile's range extended and a new 300kt thermonuclear warhead added.[5]


The studies for the successor to the ASMP-A, dubbed ASN4G (air-sol nucléaire de 4e génération), have already begun.[10] The aim is to design a missile capable of either high supersonic (Mach 4–5) or hypersonic speeds (Mach 7–8).[11][12] The ASN4G could be carried by the Rafale fighter jet and the requirement is for a missile range much greater than 1,000 kilometers.[13][14] ASN4G is being developed and will be manufactured by ArianeGroup.[15]
