Overview

The United States is Israel's primary defence partner and the backbone of the multinational coalition defending against Iranian strikes. US involvement has escalated from intelligence sharing and behind-the-scenes coordination in Round 1 to direct kinetic defence and becoming a target of Iranian strikes in Round 4. US Central Command (CENTCOM) coordinates regional defence from Al Udeid Air Base, Qatar, with assets distributed across the Gulf.

Key Defence Contributions

THAAD Battery

Terminal High Altitude Area Defense deployed to Israel in October 2024, providing an additional upper-tier intercept layer. The AN/TPY-2 radar extends early warning capability significantly.

See: THAAD detail

Aegis BMD (Naval)

Aegis-equipped destroyers and cruisers in the Eastern Mediterranean and Red Sea provide SM-3 and SM-6 intercept capability. USS Carney and USS Mason conducted the first combat intercepts of Houthi missiles.

Carrier Strike Groups

Continuous carrier presence in the region since October 2023. CSGs provide fighter intercept, Aegis BMD, ISR, and power projection. Two carriers maintained simultaneously during peak escalation.

ISR & Early Warning

US satellite constellation, SIGINT, and airborne platforms (RC-135, E-3 AWACS, MQ-9) provide launch detection, tracking, and intelligence sharing with Israel in real-time.
