The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the repair and modification of the Transmitter Subassembly, NSN 7H-6680-015991697. The procurement involves a quantity of 16 units, which will be delivered to designated DLA distribution centers in New Cumberland, PA, and Tracy, CA. This equipment is critical for measuring liquid and gas flow, and the government has determined that it is uneconomical to purchase the necessary data or rights for alternative sources, thus limiting the solicitation to a single source under FAR 6.302-1. Interested parties are encouraged to express their interest and capability within 45 days of this notice, and they may contact Naryan Smith at (717) 605-1332 or via email at NARYAN.SMITH.CIV@US.NAVY.MIL for further details.
