The 145 Squadron "Hornet" is a strike fighter squadron of the Republic of Singapore Air Force based currently at Changi Airbase (East) which is a new airbase, opened in 2004, to the east of Singapore Changi Airport on reclaimed land.

Due to ongoing construction works for Changi Airport Terminal 5 & runway expansion, this flight squadron is based at Tengah Airbase.

With the hornet as its mascot, the squadron's motto is "Swift & Valiant".

[1] The twenty aircraft of the squadron are upgraded versions of the F-16D Block 52, hence known as the Block 52+ or F-16D+, are equipped with state-of-the-art Conformal Fuel Tanks, an enhanced radar with greater detection range and improved mapping capabilities, and an improved targeting pod, this enables the squadron to conduct precision day and night operations at a greater combat range and duration.

This made it a unique squadron within the RSAF as all its aircraft are tandem seaters and every mission is flown with a Pilot and Weapon System Officer (WSO), until the arrival of the F-15SG Eagles with 142 and 149 Squadrons.
