The Northrop Grumman APG-81 radar is set to begin radome integration testing with the Lockheed Martin F-35 Joint Strike Fighter. The fire-control system, which includes an active electronically scanned array, will then be returned to Northrop's Baltimore facility, where it is set to begin flight tests on a BAC One-Eleven. The flight tests will encompass the APG-81's three modes – air-to-air, air-to-surface and electronic warfare, says Northrop. The company also is developing the F-35's electro-optical distributed aperture system and electro-optical targeting system.
