DARPA's "Perrseus" solicitation closes in two days, seeking compact cold-atom devices and ultra-high Q MEMS and photonic components built on microscale ultra-high-vacuum systems. The Air Force's high-voltage radiation-hardened power switch notice also expires in two days, aiming to enable next-generation electric propulsion and space-based power. Four open requirements will close within the next seven days and eight more will close within thirty days. The Department of Defense leads the week with seven active solicitations, followed by the Department of War with three. Across agencies, the focus this week is on quantum hardware, space power, directed-energy lasers, brain-inspired AI, and biotechnologies for warfighter protection.
