The Department of Defense, through the NAVSUP Weapon Systems Support office, is seeking to procure seven Backplane Assemblies under a sole source contract with DRS Environmental Systems Inc. The procurement involves the purchase of NSN 1R-5998-014608703-SF, P/N 735345-301, which is critical for repair support, as the government does not possess the necessary data to source this part from alternative manufacturers. Interested parties are encouraged to submit capability statements or proposals within 30 days of this notice, with the solicitation expected to be issued on November 17, 2025, and a closing date of December 22, 2025. For further inquiries, interested organizations may contact Jason J. Sklencar at jason.j.sklencar.civ@navy.mil.
