Responsive launch, defending U.S. satellites in geosynchronous orbit and a proliferated satellite constellation in low Earth orbit may all be tools for defending against adversaries in space, but the nation needs to keep all options open through funding all avenues, according to the U.S. Air Force’s acquisition executive.

Raytheon has demoed a land-based expeditionary version of its Joint Precision Approach and Landing System for the first time to the USAF, Navy and Marine Corps.

The head of U.S. Strategic Command believes there is merit in pursuing a proliferated constellation of satellites in low Earth orbit, but warns the nation should not go “all in” on a technology that has not been proven.
