Sembawang Air Base

Before Singapore's independence from the United Kingdom, it was a Royal Air Force station known as RAF Sembawang as well as being the Royal Naval Air Station – HMS Simbang – to the carrier pilots of the Royal Navy Fleet Air Arm (attached to the Eastern Fleet based in Singapore) who used it for rest and refit whenever an aircraft carrier of the Royal Navy berthed at the nearby HMNB Singapore for refuel and repairs, which also housed the largest Royal Navy dockyard east of Suez up to the time of UK forces withdrawal from Singapore.

After the Japanese capture of Singapore during World War II, the Imperial Japanese Navy Air Service took over the two RAF stations of Sembawang and Seletar. Singapore was split into north–south spheres of control, and the Imperial Japanese Army Air Force took over RAF Tengah. It was not until September 1945 that the two airfields reverted to British control following the Japanese surrender.

RAF Sembawang was a key part of Britain's continued military presence in the Far East (along with the three other RAF bases in Singapore: RAF Changi, RAF Seletar, RAF Tengah) during the critical period of the Malayan Emergency (1948–1960), the Brunei Revolt in 1962 and the Indonesia–Malaysia confrontation (1962–1966).

The base was renamed Sembawang Air Base (SBAB) in 1971 when it was handed over to the Singapore Air Defence Command (SADC). From 1971 to 1976, under the auspices of the Five Power Defence Arrangements (FPDA), Sembawang housed British, Australian and New Zealand forces.

In 1983, the airbase became a full-fledged rotary-wing air base when the first resident helicopter squadron – 120 Squadron – was permanently relocated from Changi Air Base.

In the late 1990s, the extension of Sembawang Airbase has acquired the portion of Lorong Gambas and Lorong Lada Merah for redevelopment works.
