When the PAF decided to acquire the Chengdu J-10CEs, the 15 Squadron was chosen to be equipped with it. The 15 squadron's previous fleet of PAC upgraded Mirage-VEF ROSE-IIIs were still capable enough in modern warfare and since the PAF high command wasn't in the favor of retiring them, the No. 50 Squadron was raised on 1 December 2021 to inherit all of the No. 15 Squadron's Mirages and related assets.
