With the induction of B-57 bombers in the PAF, an operational conversion unit was raised at Mauripur on 15 August 1959, to train pilots and navigator-bombardiers for No. 8 B-57 Squadron. The training unit was named No 10 Squadron and it carried out its assigned task for a little over six months.

In March 1960, a second operational B-57 squadron, No. 7, was formed which, together with its sister unit No 8 constituted No. 31 Wing. Consequent upon this development, No. 10 Squadron was number-plated on 1st March 1960.
