TheBoeing XP-15 was an American prototypemonoplanefighter.
This aircraft was essentially a monoplane version of theBoeing P-12, differing in having the lower wing omitted and in having all-metal construction as well as alteredailerons. The XP-15 had a split-axleundercarriage and atail wheel.[1]
Boeing numbered the craft as itsModel 202; while theUnited States Army accepted it for testing and designated it as XP-15, they never actually purchased it, and it retained its civil registration of X-270V.[1]
The XP-15 first flew in January 1930, when it was discovered that thevertical stabilizer (a P-12C type) needed to be larger in order to compensate for the single wing. Initial testing showed a top speed to 178 mph, but with enlarged tail surfaces and aTownend cowling, it recorded 190 mph at 8,000 ft. The aircraft performed poorly, with a poorrate of climb and a high landing speed. The USAAC did not order the aircraft for production and on 7 February 1931, the prototype was destroyed when apropeller blade failed and the engine tore loose from its mounts.[1]
The Navy was offered the similarModel 205. It first flew in February 1930. One was bought by theUS Navy as the XF5B-1, but by the time flight testing was complete in 1932, other aircraft were ordered instead.
