ELLSWORTH AIR FORCE BASE, S.D. (AP) — B-1 bombers at Ellsworth Air Force Base are again flying at a combat-mission-ready rate after being mostly grounded in April due to budget cuts.

The grounding affected about one-third of the Air Force's active-duty combat aircraft, including squadrons of fighters bombers, and airborne warning and control craft.

Base officials say that only a small portion of non-deployed aircrews at Ellsworth flew during the limited flying hours period.

The Defense Department received authority from Congress to shift about $7.5 billion from lower priority accounts to more vital operations. The Air Force says the restored flying hours represent about $208 million of that allocation authorized by Congress.

The restoration of flying hours will last through Oct. 1.
