The T-47A was a modified version of the Citation S/II (Model 552) for the U.S. Navy, featuring a wingspan reduction and hydraulically boosted ailerons for enhanced maneuverability, thrust JT15D-5 engines, a cockpit roof window for better pilot visibility during hard maneuvering, strengthened windshields for protection against bird strikes during high-speed low-altitude sorties, multiple radar consoles, and the AN/APQ-167 radar system. Intended to replace the North American T-39D as a radar systems trainer aircraft, fifteen aircraft were purchased to train Naval Flight Officers, primarily radar intercept officers, A-6 Intruder bombardier/navigators, EA-6B Prowler electronic warfare officers, F/A-18D Hornet weapon systems officers and S-3 Viking copilot/tactical coordinators.
