The P.11, with a distinctive high-mounted gull wing, had its origins in the P.7 of 1931 and a supply of Bristol Mercury engines. By 1934, the P.11a entered production, although 50 P.11b's (identical in game terms) were produced first for Romania. The P.11c entered service in 1936 and featured much better visibility for the pilot. Some 175 of the P.11c were ready when the Germans invaded in September of 1939. The tweleve Polish squadrons downed 126 Luftwaffe aircraft while losing 114, depite the plane being all but obsolete. Five Romanian P.11 squadrons remained in Romania for training and home defense, the plane being finally retired in 1942.
Some 435 P.11's of all types were built, with 130 going to Romania. The P.11c burns 21.6 gallons of fuel per hour at routine usage.

Design Notes
Design aSpeed is 267 mph; the historical speed, as well as actual wing
area (193 sf), has been used.
To reduce weight and a rather high aMR, the wing cost, weight and HPs were divided by two.
Variants
The P.11a had a weaker Skoda engine (370-386 kW) and poorer visibility.
The fuselage MGs had 700 rpg (the wing MGs were not present yet). It had
78 and 3 gallon fuel tanks (the larger of which could be jettisoned in
an emergency).
The 50 Romanian P.11b's were similar to the P.11a's, but used a 391-kW engine.
Roughly one fifth to one third of the P.11c's were delivered with the wing MGs missing, due to weapon shortages. Some planes also used the 7.92mm PWU Wz 33 MG instead. Finally, some early planes of this version used 418-kW engines.
The P.11f was the Romanian version of the P.11b, with 80 built.
The proposed P.11g Kobuz would have mounted a much larger 629-kW engine, but none had been built before Poland was invaded.
