The XP-15 was built by Boeing as a single-wing version of the P-12 and given the company designation Model 202. The aircraft was tested by the Army Air Corps but never actually purchased and carried only the civil registration X-270V. Although the XP-15 never entered production, Boeing used the all-metal fuselage design and improved tail assembly on the P-12E production aircraft. The only XP-15 built was destroyed in a crash on Feb. 7, 1931.
