Although the P.7 had better manoeuvrability than their German opponents and could operate from short fields (150 m to start), even rough ones, almost all the German aircraft were faster than the P.7a. Furthermore, the Polish aircraft and their engines were worn out from intensive service use. Their armament was also insufficient – only two Vickers machine guns in most aircraft, which had a tendency to jam (only from aircraft number 6.109 they were replaced with better PWU FK wz.33). For these reasons, the pilots flying the P.7a claimed shooting down only seven German aircraft (two He 111s, two Do 17s, one Hs 126 and two Bf 110s), suffering combat losses of 22 aircraft. An improvised task force of P.7a aircraft from units at air bases was rather to confuse and disturb the German bombing raids with their aggressive presence, than to shoot down bombers.
