Reports indicate that Israeli defense companies Elbit Systems and Israel Aerospace Industries have quietly supplied advanced defense systems, including missile‑defense technology, to aircraft operated by Saudi Arabia and Qatar. According to U.S. government documents and contracts, the C‑MUSIC system from Elbit is installed on Royal Boeing 747s and Airbus Qatars, while Israeli-made components are used in Saudi F‑15 fighters. These arrangements demonstrate that operational defense cooperation between Israel, Saudi Arabia, and Qatar continues despite the absence of formal diplomatic ties.
