[U.S. Military "Patriot" and "THAAD" Missile Defense Systems Participate in Israel's Air Defense Operations] Anonymous U.S. defense officials have reported that the "Patriot" and "THAAD" missile defense systems, operated by U.S. personnel and deployed as early as the Biden administration, have participated in Israel's air defense operations. Compared to the extensive involvement of U.S. aerial and naval forces in assisting with missile interceptions during two retaliatory attacks against Iran last year, the scale of this operation is noticeably smaller.
