Harpy

Pioneering anti-radiation loitering munition (also categorised as a SEAD UAV) that established the concept of autonomous suppression of enemy air defences through expendable platforms. The Harpy autonomously loiters over a designated area for up to 9 hours, using its wideband passive radar seeker to detect, classify, and home in on enemy radar emissions — diving into the radar antenna with a 32 kg blast-fragmentation warhead. Launched from a ground-based container (18 per launcher), the Harpy features a 2.1-metre wingspan, delta wing configuration, and small turbojet engine with a range of 500 km. Once launched, the Harpy operates fully autonomously — a fire-and-forget SEAD weapon requiring no operator control or datalink. This autonomous operation provides a critical advantage when enemy air defences may jam or destroy communication links. Widely exported including to South Korea, Turkiye, India, and China (the latter sale caused significant US diplomatic friction). The Harpy pioneered the loitering munition concept that has since become a global trend.
