Abstract: A novel airborne reactive threat simulator is presented. The simulator comprises an aircraft flight and carrier qualified podded external store and a cockpit mounted system control box. The pod is capable of supersonic flight envelopes and houses a sophisticated, state-of-the-art, microprocessor controlled, programmable tracking radar system and associated data collection peripherals. The control box provides the operator/machine interface during system operation. The system operates from a library of preprogrammed scenarios, which are selected by the pilot of the aircraft during routine training/testing exercises. A threat simulation scenario is selected by the pilot as the pilot flies a predetermined profile mission against a target ship. The software routine is executed by the microprocessing system which in turn controls all system hardware components and peripherals.
