The SRAM II (Short-Range Attack Missile) was a nuclear air-to-surface missile intended as a replacement for the AGM-69 SRAM, but it was cancelled by President George H.W. Bush for geopolitical reasons just as the first flight-test missile was delivered. In 1977, the USAF planned to develop an upgrade of the SRAM for the forthcoming B-1A bomber as AGM-69B SRAM B. When the B-1A was cancelled in 1978, the AGM-69B was dropped, too. After the resurrection of the B-1 program (as B-1B) in 1981, it was decided to develop an entirely new weapon, the SRAM II.
