With the departure of the 97th Bombardment Wing, the Eielson Air Force Base Wing (Base Complement) was formed on 1 April 1948. On 20 April 1948, it was designated the 5010th Air Base Wing, and would be the host unit at the base until 1964. Construction boomed at Eielson AFB during the wing's tenure in the 1950s. Many of the facilities still in use today were built at that time – Amber Hall, the Thunderdome, Base Exchange, Commissary, Gymnasium, Theater, Base Chapel, some of the schools and many of the dormitories, just to name a few.
