What is the Harpy loitering munition and how does it function?

The Harpy is an anti-radiation autonomous weapon system designed to target enemy air defense systems. It operates by being loaded with the signatures of opponent systems and given a basic mission plan and area of operation. Once launched, it patrols autonomously until it identifies the radar signatures of opposing air defense systems, at which point it engages the target with its explosive payload. According to IAI's website, the Harpy is fully autonomous and effective in SEAD (Suppression of Enemy Air Defenses) missions from both land and naval platforms. This type of autonomous system helps minimize civilian casualties as it specifically targets military radar emissions.
