The Armement Air-Sol Modulaire (Air-to-Ground Modular Weapon) (AASM) 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. It entered service in 2007 with the French Air Force and Naval Aviation, from Rafale and Mirage 2000. It is also known as HAMMER (Highly Agile Modular Munition Extended Range).
