The PZL.38 Wilk ("wolf") (PZL-38) was a Polish fighter-bomber developed and manufactured by PZL state factory in 1937.

Design and development

In 1934 the Polish Air Force ordered a new multi-role heavy fighter-bomber. It was initially supposed to replace fighters in both pursuit and escort duties and light bombers (at that time, such idea was popular in the world, what resulted in aircraft, like Bf 110). In an internal PZL competition a design of the engineer Franciszek Misztal won and was given the designation PZL.38 Wilk. In this construction was used diminished aerodynamic profile and configuration from medium bomber PZL.37 Łoś. The powerplant was to be 490-hp lightweight V-engine PZL Foka (seal), designed by Stanisław Nowkuński of Polish Skoda Works (then PZL WS-1). Unfortunately, Nowkuński died in Tatry mountains on 30 July 1936 and work on the engine slowed down. Due to technical problems, overheating and vibration, it was decided to use a foreign engine.

In 1937 two prototypes of PZL.38 were built. The second one (PZl.38/II) received the American Ranger SGV-770B engines (420-450 hp), which were less powerful than the PZL "Foka" engine. As a result the prototype didn't meet expected performance. The second prototype flew first in April or May 1936. The first prototype PZl.38/I, received the PZL Foka engine. The airplane was shown in 1938 at the Paris Air Show. It was flown only in February or March 1939 and also did not meet expected performance (estimated maximum speed was 465 km/h, while it hardly reached 400 km/h). It was also too heavy (2155 kg instead of 1715 kg) and had too small useful load. Because of these facts, further development of PZL.38 "Wilk" aircraft and "Foka" engine was abandoned in the Spring of 1939, in a favour of the new construction PZL.48 "Lampart" - which was a modification of "Wilk" with radial engines.

Operational history

After the German invasion of Poland, both prototypes were not able to fly and remained in factory at Okęcie in Warsaw. They were captured by the Germans in a damaged state, their further fate is not known.



Polish Air Force



It was a twin-engine low-wing cantilever monoplane of metal construction, metal covered. The fuselage was semi-monocoque, elliptic in cross-section. The crew of two - pilot and rear gunner/bombardier/observer sat under separate canopies, far from each other, fitted with dual controls. A canopy of pilot's cockpit opened aside. Three part wing, outer parts were built around light closed profiles. Wings fitted with slats and split flaps. Twin vertical stabilizers. Engines in underwing nacelles. Retractable landing gear, with main wheels retracting into engine nacelles, and a rear skid. Three-blade variable (P.38/I) or two-blade fixed propellers (PZL.38/II). Fuel tanks in wings - 500 l. Armament: fixed 20 mm FK-A gun (planned) and two 7.92 mm PWU wz.36 machineguns in the fuselage nose, twin 7.92 mm PWU wz.37 machinegun of a rear gunner, hiding in the fuselage. It could carry one 300-kg bomb.
