As units of the Air Corps increased in number, so did higher command echelons. The 2nd Wing, activated in 1922 as part of the Air Service, remained the only wing organization in the new Air Corps until 1929, when it was redesignated the 2nd Bombardment Wing in anticipation of the activation of the 1st Bombardment Wing to provide a bombardment wing on each coast.Maurer (1987), p. 197. The 1st Bomb Wing was activated in 1931, followed by the 3rd Attack Wing in 1932 to protect the Mexican border, at which time the 1st became the 1st Pursuit Wing. The three wings became the foundation of General Headquarters Air Force upon its activation in 1935.
