In 1953 it converted to the strategic reconnaissance mission, upgrading to the Boeing RB-47 Stratojet in 1954.

[4] The 90th Missile Wing is made up of a wing staff and five groups: The 90th Operations Group is composed of three missile squadrons, an operations support squadron and a standardization and evaluation element.

The 90th Security Support Squadron provides command and control for the missile field and access control for all missile field forces as well as all security forces training and equipment support.

[7] In March 1951, the wing moved to Forbes Air Force Base, where it served primarily as a training unit.

With its departure for Schilling Air Force Base, Kansas in September 1952, the B-29 operational training mission ended.

[3][10] In June, the wing added duty as a Replacement Training Unit, primarily providing individual training for aircrew being assigned to existing Far East Air Forces B-29 units during the Korean War.

[11][note 3] In November 1952 it also began training replacement crews for the RB-29 reconnaissance model of the Superfortress and SHORAN personnel for Strategic Air Command (SAC).

[3] The following year, it replaced its RB-29s with the jet Boeing RB-47 Stratojet, with the first B-47E arriving on 25 June, although crews had begun training in March.

[3] However, in 2001 and in compliance with the Strategic Arms Reduction Treaty, these missiles were limited to a single reentry vehicle[4] The wing supervised LGM-118 Peacekeeper personnel training and facility preparation beginning Jun 1985.

The Peacekeeper, which could carry ten independently targeted reentry vehicles,[4] was fully operational with the wing's 400th Strategic Missile Squadron on 30 December 1986.

The Peacekeeper system continued in operation in addition to the wing's Minuteman missiles until September 2005, when it was retired and the 400th Squadron inactivated.

[3][18] Although it remained a component of Twentieth Air Force, starting in 1992, the wing was reassigned under three different major commands over the next twenty years.
