The squadron flew the B-47 for about a decade when by the mid-1960s it had become obsolescent and vulnerable to new Soviet air defenses. The squadron began to send its Stratojets to the Aerospace Maintenance and Regeneration Center at Davis-Monthan Air Force Base, Arizona for retirement in 1965, and the unit inactivated in 1966. The squadron reactivated as a General Dynamics FB-111A Aardvark strategic bomber squadron in 1970 when aircraft became part of SAC's nuclear deterrent force. It was inactivated in 1990 with retirement of that weapons system. The Air Force Chief of Staff directed the creation of the B-2 Division, USAF Weapons School in May 2002. On 13 August 2003, the B-2 Division was replaced by the squadron, now designated the 715th Weapons Squadron and activated at Whiteman Air Force Base, Missouri as an advanced instructional unit. The 715th was separated from its headquarters, the 57th Wing, stationed at Nellis Air Force Base, Nevada. It was inactivated, and its assets transferred to the 325th Weapons Squadron on 9 September 2005.
