No. 15 Squadron was raised in 1951 at Ambala as part of an emergency wartime expansion. Initially operating with just a handful of Spitfire XVIII taken out from a training role, it was among the four "teen squadrons" set up to bolster the IAF’s strength in anticipation of conflict.{{cite web |last=Gupta |first=Anchit |title=The Emergency Teen Squadrons: IAF’s Quiet Expansion in 1951 |url=https://iafhistory.in/2025/05/04/indian-air-force-1951-expansion/ |website=IAFHistory |date=4 May 2025 |access-date=4 May 2025}}
