NAVSUP Weapon Systems Support Philadelphia is seeking a single source contractor to provide Performance Based Logistics support for various components of the ALR-67(V)3 radar warning system on the F/A-18 aircraft. The government intends to negotiate with only one source under FAR 6.302-1, as it lacks the necessary data to perform the repairs or manufacture itself. This is a sources sought notice, not a formal request for competitive proposals, though responses received within 15 days of the notice's publication will be considered. The items are subject to the Buy American Act, and source approval is required, with award not being delayed for pending approvals. The point of contact is Colleen Courtney.
