The Vought VE-7 "Bluebird" was an early biplane of the United States. First flying in 1917, it was designed as a two-seat trainer for the United States Army, then adopted by the United States Navy as its first fighter aircraft. In 1922, a VE-7 became the first airplane to take off from an American aircraft carrier.[1]
Design and development
The
However, the Navy was very interested in the VE-7, and received the first machine in May 1920. Production orders soon followed, and in accordance to Navy policy at the time, examples were also built by the Naval Aircraft Factory. In all, 128 VE-7s were built.[1]
The fighter version of the VE-7 was designated VE-7S. It was a single-seater, the front cockpit being faired over and a .30 in (7.62 mm)
The Bluebird won the 1918 Army competition for advanced training machines.[2]
The VE-8 variant completed in July 1919 had a
The VE-9 variant, first delivered to the Navy on 24 June 1922, was essentially an improved VE-7, with most of the improvements in the fuel system area. Four of the 21 ordered by the U.S. Navy were unarmed observation float seaplanes for battleship catapult use.[3]
Operational history
The VE-7s equipped the Navy's first two fighter squadrons VF-1 and VF-2. A VE-7 flown by Lieutenant Virgil C. Griffin made history on October 17, 1922, when it took off from the deck of the newly commissioned carrier Langley. The VE-7s were the Navy's frontline fighters for several years, with three still assigned to the Langley in 1927; all were retired the following year.[1]
