The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the repair and modification of navigational instruments, specifically under the title "66--COMPUTER SUBASSEMBL, IN REPAIR/MODIFICATION OF." The procurement involves the repair of 10 units of NSN 7R-6605-014755786-KB, with a defined Repair Turnaround Time (RTAT) and throughput constraints that must be adhered to by the contractor.

Interested parties should contact Kathryn Elechko at (215) 697-2782 or via email at KATHRYN.ELECHKO.CIV@US.NAVY.MIL, with proposals due within 45 days of the notice publication.
