The Department of Defense, through the Naval Surface Warfare Center (NSWC) Crane, is seeking to procure hydrophone housing, specifically part number 6029163-301 Rev L, from Stark Precision Machine, LLC. This procurement includes the requirement for first article testing, which entails the manufacturing and testing of five housing units, with a test report due within 14 days post-inspection before full production of an additional 53 units can commence. The hydrophone housing is critical for military applications involving underwater sound equipment, and the contract is being issued as a sole source under FAR 13.106-1 due to the need for vendor qualification. Interested vendors must submit their capability statements by the closing date of August 11, 2025, at 11:00 AM Eastern Time, and all proposals should be directed to Morgan Helton at morgan.m.helton.civ@us.navy.mil.
