The U.S. Navy seeks contractors to evaluate, repair, and/or modify a specific list of 13 NIIN items. The Government intends to solicit limited sources, as it does not possess the data needed for the repairs and has identified Laurel Technologies Partnership and Northrop Grumman Systems Corp. as potential sources. This is a sources sought notice, not a competitive solicitation, but responses will be considered if received within 15 days of the notice's publication. The performance location is Mechanicsburg, Pennsylvania. Interested parties must be or become an approved source, with specific submission requirements for source approval.
