Lockheed Martin, developing the advanced training programme to support the build-up, has completed the software loads for the aircraft, which features new cockpit, flight control, navigation and weapon systems and the ARG-1 radar - a Northrop Grumman APG-66 derivative. "What you end up with is similar to the [Lockheed Martin] F-16 Block 50," says Cal Felte, Lockheed Martin A-4AR flight training manager. The training will initially focus on developing the A-4AR's advanced navigation and air-to-ground capabilities. "After that we'll go into all the air-to-air capabilities," says Felte.
