The Naval Undersea Warfare Center in Newport, RI intends to purchase 40 SpaceX Walkman Block 2 radios on a sole-source, firm-fixed-price basis, as no other radio meets the required size, weight, and power constraints. Delivery is required by October 31, 2026, with performance at the destination in Newport, RI. No budget amount is specified. This is not a competitive solicitation, but quotes may be considered for future competitive procurement.
