The PZL P.11 was an innovative fighter aircraft of the early 1930s, possessing high-mounted gull wings, as well as an all-metal, metal-covered structure. It also possessed several relatively conventional features for the era, such as its use of a fixed undercarriage arrangement. In terms of armament, the P.11 was equipped with a pair of 7.92 mm machine guns mounted upon the sides of the fuselage; reportedly, around a third of all P.11c-model fighters were provisioned with two additional machine guns fixed onto the wings. The fuselage-mounted guns were synchronised, but all others were not; a gun camera could also be installed. In terms of bombs, the P.11c could carry up to four small 12.5 kg bombs, while the earlier P.11a model was not provisioned to carry any.
