“The destruction of a US E-3 Sentry airborne warning and control system (AWACS) aircraft in an Iranian strike on a Saudi Arabian airbase has raised questions over how a critical surveillance asset was left unprotected, and how Iran was able to launch a direct strike on the plane.”

“The plane was one of 16 operational E-3s, which first went into production in the 1960s and carry sophisticated monitoring equipment that allow them to warn of airborne threats such as missiles, as well as surveil and monitor their assigned battle space including communications, troop and equipment movements and air defence sites.”

“The attack that destroyed it on 27 March, while it was parked at Prince Sultan airbase, underlined once again the continuing ability of Iran to attack and accurately strike high-value targets in the region despite a month of US and Israeli air raids.”
