Established on 1 Apr 1984 at Tengah Air Base, 145 Squadron first started flying the A4 Skyhawks. After nearly two decades of service, the Squadron retired its ageing A-4 fleet in April 2003 and prepared for re-location to the new Changi base, and for the arrival of the state-of-the-art F-16D Block 52+ fighters.
