The Air-Sol Moyenne Portée (ASMP; medium-range air to surface missile) is a French nuclear air-launched cruise missile. 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 missile cost $600 million to develop.
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 earlier Mirage IVA was retired in 1996, although Mirage IVP photo reconnaissance aircraft continued in French Air Force service until 2005.
ASMPA is 5.38 m long and weighs 860 kg. It is a supersonic standoff missile powered by a liquid fuel ramjet. It flies at Mach 2 to Mach 3, with a range between 80 km and 300 km (ASMP)/ 500 km (ASMPA) depending on flight profile. Warhead was a single 300 kt of TNT TN 81 for ASMP, and a single 300 kt of TNT Airborne Nuclear Warhead (TNA).
An advanced version known as Air-Sol Moyenne Portée-Amélioré ASMP-A (improved ASMP) has a range of about 500 kilometres (310 mi) at a speed of up to Mach 3 with the new TNA (tête nucléaire aéroportée) 300kt thermonuclear warhead. It entered service in October 2009 with the Mirage 2000NK3 of squadron EC 3/4 at Istres and on July 2010 with the Rafales of squadron EC 1/91 at Saint Dizier.
Back of ASMP-A mock-up
The studies for the successor to the ASMP-A, dubbed ASN4G, have already begun. ASN4G refers to air-sol nucléaire fourth-generation. The aim is to design a missile capable of either high supersonic (Mach 4-5) or hypersonic speeds (Mach 7-8)
