Procurement
Consideration to replace the Hawker Hunter in service as fighters was given in 1975; the choice was to be between th McDonnell F-4, the Northrop F-5E and the IAI Kfir.

By late 1976 a Letter of Offer for the supply of 18 Northrop F-5E and 3 F-5F, plus 200 AIM-9J Sidewinder aif-to-air missiles at a total price of USD 109.7m, later increased to USD 113.0m, was taken up by the Government of Singapore. The two-seaters were to be delivered by late 1978, 15 single-seaters at two-a-month starting January 1979 and the final (attrition aircrafts) three in December 1979.

The first batch of 7 aircrafts arrived at Tengah AB on 19-02-79 on board an Lockheed C-5A Galaxy, two other batches followed the same way, delivery was completed by October 1979.
Instructor pilots converted to the new aircraft at Luke AFB (USA) with the 425th Squadron, including live-firing exercises.

The sale of additional 6 Northrop F-5E was notified to the US Congress in July 1980, contract valued at approximately USD 33.8m including spares. These aircrafts figured some improvements, like an extended dorsal fin, wing leading edge and the "sharkmouth" nose; they were delivered mid-1981.

Purchase of three more Northrop F-5F followed in 1982, costing USD 16.3m. These were air-delivered in February 1983 via the Atlantic Sea (8 days, US pilots) and the Middle East (8 days), a journey through 16 countries and 14'800 km long; Singaporean pilots took-over the aircrafts at RAF Leuchars (UK) and flew them home via France, Italy, Greece, Cyprus, Egypt, Saudi Arabia, Bahrain, Qatar, UAE, Oman, Pakistan, India, Bangladesh, Burma, Thailand and Malaysia.

One Lockheed KC-130H was delivered in 1984, followed by four Lockheed C-130B converted in 1985/1986 to KC-130B air-refuellers in order to enable the in-flight transfer, mainly to exercise in Australia, of the Northrop F-5s (and STAe A-4).

Another 6 Northrop F-5E were delivered in 1985. These participated in mid-November of this year to a Red Flag exercise at Nellis AFB before being flown home via the same route, five immediately after the exercise, one at the beginning of December.

April 1987 saw the commission of of the Flight Simulation Center with an F-5 air combat simulator at Paya Lebar AB, one of the best in South East Asia, extensively used by the Air Forces of Malaysia and Indonesia. By April 2010 there were four simulators at Paya Lebar AB.

A batch of 5 additional Northrop F-5E were received in 1989. These were built from stock parts, as the production line had already closed down, again air-delivered via the Atlantic route. This brought the grand total of 35/36 single- and 9 double-seaters.

Primary role of these aircrafts was air defence, armament including Raytheon AIM-9P Sidewinder (which have supplanted the AIM-9J version), followed by strike. For this last role Hughes AGM-65A Maverick were acquired, plus Mk 82 500lbs bombs and LAU-60/A and -68/A rocket launchers.

Final acquisition were seven former Jordanian AF Northrop F-5E, bought in 1994. These were probably directly modified as STAe/Northrop F-5S

New main air-defence fighter

Replacement of the STAe/Northrop F-5S as the main Singaporean fighter came with the progressive establishment, between August 1998 and 2004, of three General Dynamics F-16 equipped Squadrons, initially armed with the F-16A and F-16B version, later with General Dynamics F-16C and F-16D Block 52+ versions, though the updated Northrop fighter still remained a very important pillar in Combat Air Patrols, sweep and escort missions and interception of hostile aircrafts.

There were 49 aircrafts in service in 2004 according to an US source.


Camouflage
Aircrafts were originally delivered in a three-tone grey camouflage scheme. Beginning 1995 repainting in a two-tone grey scheme (similar to local F-16s) started, to be completed by late 1996 on aircrafts belonging to 149 Squadron.
Various experimental colours were applied on some aircrafts during the 1980s/early 90s. They included a 3-tone blue, SEA camouflage and one natural metal.
