THAAD

Reference data current as of March 2026.

THAAD (Terminal High Altitude Area Defense) is the US Army's premier ballistic missile defence system, designed to intercept short-, medium-, and intermediate-range ballistic missiles during the terminal phase of flight. The system uses hit-to-kill technology — destroying incoming warheads through direct kinetic impact rather than explosive fragmentation. Its AN/TPY-2 X-band radar is one of the most powerful mobile sensors in existence, capable of detecting and tracking ballistic missiles at ranges approaching 1,000 km. A single THAAD battery comprises six truck-mounted launchers carrying eight interceptors each, a fire control unit, and the AN/TPY-2 radar, providing a 48-round magazine for sustained engagement. THAAD fills a critical gap in the layered defence architecture between upper-endoatmospheric systems like Arrow-2 and exoatmospheric interceptors like Arrow-3, engaging threats at altitudes of 40–150 km.

• Hit-to-kill kinetic intercept — no explosive warhead, destroys threats through direct impact
• Endo- and exo-atmospheric capability (40–150 km altitude), bridging Arrow-2 and Arrow-3 engagement zones
• AN/TPY-2 X-band radar with ~1,000 km detection range — one of the most powerful mobile BMD sensors in existence
• 48-interceptor battery loadout across six mobile launchers for sustained salvo defence
• Fully road-mobile and rapidly deployable — operational within hours of arrival
• Integrated with Link 16 and C2BMC for multinational sensor fusion with Israeli and Aegis systems
• At ~$12M per interceptor, represents significant cost-exchange pressure against cheaper offensive missiles

THAAD achieved its first combat intercept in January 2022 when a battery deployed to the UAE engaged Houthi ballistic missiles targeting Abu Dhabi. In October 2024, the United States deployed a THAAD battery to Israel — only the second overseas deployment in history — ahead of anticipated Iranian retaliation that became True Promise 2. The battery, operated by US Army soldiers on Israeli soil, has remained in place through Rounds 3 and 4, contributing to the high-altitude intercept band alongside Arrow-2 and Arrow-3. Specific intercept data from Israeli operations remains classified, but the AN/TPY-2 radar is confirmed to serve as a critical sensor node, feeding track data to Israeli and Aegis systems via Link 16 for shoot-look-shoot engagement sequences.
