AASM Hammer

A modular French rocket-boosted precision glide-bomb kit that transforms 125–1,000 kg standard bombs into all-weather, jam-resistant stand-off weapons, operational since 2008 and a linchpin of Ukraine's air-to-surface strike capability against Russian GPS denial.

Overview

The AASM (Armement Air-Sol Modulaire), marketed as the Hammer (Highly Agile Modular Munition Extended Range), is a family of bolt-on guidance and range-extension kits manufactured by France's Safran Electronics & Defense. Fitted to existing general-purpose bomb bodies ranging from 125 kg to 1,000 kg, the kit combines rear-mounted folding fins and a solid-propellant rocket booster with a nose-mounted guidance section, producing a "rocket-bomb hybrid" capable of all-weather precision attack from stand-off distances and low-altitude release profiles. The weapon has been combat-proven in French service since 2008 and has become a signature Western munition in the Russo-Ukrainian War, where its resistance to GNSS jamming sets it apart from unboosted allied glide bombs.
