https://en.wikipedia.org/wiki/Seversky_P-35
The Seversky P-35 was a fighter aircraft built in the United States by the
Seversky Aircraft Company in the late 1930s. A contemporary of the Hawker
Hurricane and Messerschmitt Bf 109, the P-35 was the first single-seat fighter
in U.S. Army Air Corps to feature all-metal construction, retractable landing
gear and an enclosed cockpit.
When the USAAC announced a competition for a new single-seat fighter in 1935,
Seversky sent the SEV-2XP, confident it would win despite being a two-seater.
However, the aircraft was damaged on 18 June 1935 during its transit to the
fly-offs at Wright Field. To compete with the Curtiss Model 75, a single-seat
aircraft with retractable undercarriage, Seversky rebuilt the aircraft into the
single seat SEV-1XP, replacing the SEV-2XP's fixed landing gear with a
retractable undercarriage where the mainwheels retracted backwards into the
wing, and an 850 hp (634 kW) R-1820-G5 replacing the -F3 of the SEV-2XP. The
SEV-1XP was delivered to Wright Field on 15 August for evaluation, which was
generally successful, although the Cyclone failed to deliver its rated power and
the SEV-1XP only reached 289 mph (465 km/h) rather that the 300 mph (483 km/h)
predicted by Seversky.

The first P-35s were delivered to the 1st Pursuit Group (27th, 71st and 94th PS)
stationed at Selfridge Field in Michigan. The aircraft utilized a wet wing to
save weight and ground personnel quickly learned about the persistent fuel
leaks. The P-35's performance was poor even by contemporary standards and,
although USAAC aviators appreciated the aircraft's ruggedness, it was already
obsolete by the time deliveries were finished in 1938.[23]
