The Armement Air-Sol Modulaire (Air-to-Ground Modular Weapon) (AASM) "Hammer" is a French Precision-Guided Munition developed by Safran Electronics & Defense. 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.
It entered service in 2007 with the French Air Force and Naval Aviation, from Rafale and Mirage 2000. In 2011, AASM was given the name HAMMER (Highly Agile Modular Munition Extended Range). Chosen for commercial reasons, the English acronym is also used in French. The French pronunciation of "AASM" was deux-A-S-M or A-deux-S-M.
