|140 Squadron, Republic of Singapore Air Force|
|Motto||"Stand Firm in Defence"|
The 140 Squadron "Osprey" of the Republic of Singapore Air Force currently operates twelve F-16 Fighting Falcon of the F-16C/D Block 52 version. Based in Tengah Air Base, the squadron goes by the motto "Stand Firm in Defence" with the Osprey adopted as its mascot.
The Squadron was set up in February 1970 as Singapore's first Air Defence Fighter Squadron and received their first aircraft - two refurbished Hawker Hunters aircraft in July 1970. The Hawker Hunters served faithfully for twenty years, after which they were replaced by the F-16A/Bs in 1990. These were, in turn, replaced by newer F-16C/Ds in 2000 and were subsequently transferred to Royal Thai Air Force the same year.
