The Department of Defense, specifically the Department of the Navy, is seeking to procure 104 units of a specialized generator under the presolicitation notice titled "66--GENERATOR, FUNCTION." The procurement involves a unique National Stock Number (NSN 1H-6625-015906708-TE) and is intended for supplies or services that will be negotiated with only one source, as indicated by the authority of FAR 6.302-1. This generator is critical for electrical and electronic properties measuring and testing instruments, and its design is currently unstable, necessitating major changes to improve performance and yield. Interested parties are encouraged to express their interest and capability to respond to this requirement by contacting Brandyn Miller at (717) 605-1393 or via email at BRANDYN.MILLER@NAVY.MIL, with proposals due within 45 days of the notice publication.
