USAF PATCH 720 BOMB SQUADRON (HEAVY) B-52 US AIR FORCE SQUADRON PATCH
February 1963, The 450th Bombardment Wing was organized at Minot Air Force Base, North Dakota, where it assumed the aircraft, personnel and equipment of the discontinued 4136th Strategic Wing. The 4136th was a Major Command controlled (MAJCON) wing, which could not carry a permanent history or lineage, and Strategic Air Command (SAC) wanted to replace it with a permanent unit.As part of this reorganization, the 720th was redesignated the 720th Bombardment Squadron, was activated, and assumed the mission, personnel and equipment of the 525th Bombardment Squadron, which was simultaneously inactivated.
One half of the squadron's Boeing B-52H Stratofortresses were maintained on fifteen minute alert, fully fueled and ready for combat to reduce vulnerability to a Soviet missile strike. In addition, the squadron trained for strategic bombardment missions. Beginning in June 1968, the squadron provided aircrews to support Operation Arc Light, SAC operations in Southeast Asia. In July 1968 when SAC ended its bomber operations at Travis Air Force Base, California, the 5th Bombardment Wing moved to Minot to replace the 450th Wing. In connection with this move, the personnel and equipment of the 720th were transferred to the 23d Bombardment Squadron, which moved on paper with the 5th Wing from Travis, and the 720th was inactivated.
