The Armement Air-Sol Modulaire (Air-to-Ground Modular Weapon) (AASM) "Hammer" is a French Precision-Guided Munition developed by Sagem Défense Sécurité. AASM comprises a frontal guidance kit and a rear-mounted range extension kit matched to a dumb bomb. The weapon is modular because it can integrate different types of guidance units and different types of bombs.

The basic version features a 250-kilogram (550 lb) bomb plus hybrid inertial navigation system (INS) / Global Positioning System (GPS) guidance. Other variants add infrared homing or laser guidance to increase accuracy; there are also versions with 125-kilogram (276 lb), 500-kilogram (1,100 lb) or 1,000-kilogram (2,200 lb) bomb bodies.

The program started in 1997, when the Délégation Générale pour l'Armement (DGA), the French defense procurement agency, launched an international competition on the design for the weapon. In 2000, a contract was awarded to SAGEM for an initial lot of AASM GPS/INS bomb kits, expected at the time to be delivered from 2004 and to enter service the following year.

The first order for AASM was placed by the DGA in 2000 for a total of 744 units; deliveries started in 2007 after a two-year delay in development. In 2009 a second order for 680 units was placed, by the end of that year deliveries had reached 334.


AASM made its combat debut on April 20, 2008, during the War in Afghanistan when a Rafale fighter fired two in support of ground troops.


On 24 March 2011 it was reported that an AASM missile fired from a Dassault Rafale was used to destroy a Libyan Air Force G-2/Galeb light ground attack/trainer jet, the first Libyan warplane to challenge the no-fly zone during the 2011 Libyan civil war, on the runway just after the plane had landed at Misrata Airport.

On 6 April 2011, it was reported that a AASM missile fired from a Dassault Rafale was used to destroy a Libyan tank at a range of 55 km.
