 In the late 1970s, the Singaporean Hunter fleet was upgraded and modified by Lockheed Aircraft Services Singapore (LASS) with an additional hardpoint under the forward fuselage and another two inboard pylons (wired only for AIM-9 Sidewinders) before the main gears, bringing to a total of seven hardpoints for external stores and weapons delivery. As a result of these upgrades, they were redesignated as FGA.74S, FR.74S and T.75S. The RSAF Black Knights, Singapore Air Force's aerobatic team, flew Hunters from 1973 until 1989.
