The 818th Strategic Aerospace Division is an inactive United States Air Force organization. Its last assignment was with Strategic Air Command at Lincoln Air Force Base, Nebraska, where it was inactivated on 25 March 1965.

The division was activated at Lincoln in 1954 as the 818th Air Division to provide a single headquarters for the base as the 98th and 307th Bombardment Wings returned from Korean War operations with the Boeing B-29 Superfortress and prepared to convert to the Boeing B-47 Stratojet. From 1962 until 1964 the division also commanded a wing at Offutt Air Force Base, Nebraska. In 1962, the division assumed responsibility for a Post Attack Command and Control System squadron operating Boeing B-47 Stratojets. One month later, it was also assigned Offutt based Boeing EC-135s. performing the similar Looking Glass Mission.

The division was inactivated when the 307th Bombardment Wing inactivated, leaving the 98th Bombardment Wing as the only SAC wing at Lincoln.

In August 1954, Strategic Air Command (SAC) activated the 818th Air Division as the command headquarters for Lincoln Air Force Base, Nebraska in anticipation of the return in November of the 307th Bombardment Wing from Kadena Air Base, Okinawa, where it had been supporting Far East Air Forces in the Korean War. The 307th would join the 98th Bombardment Wing, which had moved to Lincoln in July 1954 from Yokota Air Base, Japan. The 98th's Boeing KC-97 Stratofreighters were already at Lincoln, and the two wings prepared to convert to Boeing B-47 Stratojets. The 818th Air Base Group was activated with the division, assuming responsibility for managing support activities at Lincoln from the 98th Air Base Group, which had arrived at Lincoln in November 1953 to reopen the former World War II base and prepare it for jet bomber operations.

The division was initially responsible to train its two wings for long range offensive bombardment and worldwide air refueling operations. The division participated in numerous tactical training exercises. The 98th Bombardment Wing deployed as a unit to RAF Lakenheath in late 1955. The 307th wing, which did not receive its first B-47s and KC-97s until 1955, also deployed as a unit to England in 1956.

In April 1960 the division conducted Exercise Open Road, testing Minimum Interval Takeoff of its KC-97s, with the planes departing every fifteen seconds. However, stationing slow moving KC-97s in Nebraska, near the center of North America, required them to be deployed to forward locations and the tankers of the division began to be withdrawn. Although some consideration had been given to upgrading the division's refueling units to Boeing KC-135 Stratotankers in 1960, instead, the 307th Air Refueling Squadron moved to Selfridge Air Force Base in 1960 and the 98th Air Refueling Squadron was inactivated in 1963.

In the spring of 1961, the division was assigned the 551st Strategic Missile Squadron, an SM-65 Atlas intercontinental ballistic missile unit, although the squadron did not assume full responsibility for operation of the Atlas missile sites until the fall of 1962. In the spring of 1962 SAC units with responsibility for both bomber and missile forces were renamed to include the term "aerospace" in their designations. The 818th became the 818th Strategic Aerospace Division. In 1964 the 551st was reassigned to the 98th wing, which then became the 98th Strategic Aerospace Wing.

In July 1962, the 4362d Support Squadron, which operated EB-47s of the Post Attack Command and Control System (PACCS), was activated and assigned to the division. This squadron did not become operational until 31 July 1962. Although assigned to the division, it was attached to the 307th wing.
