The Pakistan Air Force was one of the main users of the B-57 and made use of it in two wars with India. In the Indo-Pakistani War of 1965, B-57s flew 167 sorties, dropping over 600 tons of bombs. Three B-57s were lost in action (only one as a result of enemy action), along with one RB-57F electronic intelligence aircraft. During the war, the bomber wing of the PAF was attacking the concentration of airfields in north India. In order to avoid enemy fighter-bombers, the B-57s operated from several different airbases, taking off and returning to different bases to avoid being attacked. The B-57 bombers would arrive over their targets in a stream at intervals of about 15 minutes, which led to achieving a major disruption of the overall IAF effort. The then unknown Pakistani flying ace, 8-Pass Charlie, (Squadron Leader Najeeb Ahmad Khan, Sitara-e-Jurrat) was named by his adversaries for making eight passes in the moonlight, to bomb different targets with each of the B-57's bombs.
