After the attempted pre-emptive attack, the PAF adopted a defensive stance in response to the Indian retaliation. As the war progressed, the IAF continued to battle the PAF over conflict zones, but the number of sorties flown by the PAF decreased day–by–day. The IAF flew 4,000 sorties while the PAF offered little in retaliation, partly because of the paucity of non-Bengali technical personnel.
This lack of retaliation has also been attributed to the deliberate decision of the PAF's Air AHQ to cut its losses, as it had already incurred huge losses in the conflict in the liberation war in the East.The PAF avoided making contacts with the Indian Navy after the latter raided the port of Karachi twice, but the PAF did retaliate by bombing Okha harbour, destroying the fuel tanks used by the boats that had attacked.
In the East, No. 14 Squadron Tail Choppers under Squadron Leader PQ Mehdi, who was taken as POW, was destroyed, putting the Dhaka air defence out of commission and resulting in Indian air superiority in the East.
At the end of the war, PAF pilots made successful escapes from East Pakistan to neighbouring Burma; many PAF personnel had already left the East for Burma on their own before Dacca was overrun by the Indian military in December 1971.
