The heads of the U.S., British, and Australian air forces all signed a “joint vision statement” declaring their intent to work together in developing the E-7 Wedgetail for airborne early warning and control, the U.S. Air Force announced July 17. USAF did not immediately provide Air & Space Forces Magazine with exact details of the joint vision statement, but a service release noted the agreement will cover “Wedgetail capability development, evaluation and testing, interoperability, sustainment, operations, training, and safety.”
