The Air Force has awarded dual $49 million contracts to begin “major efforts to develop new or enhanced technologies” leading “into propulsion systems for a prompt global strike capability, a land-based strategic deterrent, and an operational responsive space lift system.” The two contracts went to Aerojet General and ATK Thiokol. Technology to be considered includes solid rocket motors, including ballistic and space boost, post boost propulsion, and tactical motors. Due date is 2014.
The rate of building B-21 bombers would speed up if the fiscal 2026 defense budget passes. But it remains unclear how much capacity would be added, and whether the Air Force would simply build the bombers faster, or buy more.
