The Department of Defense, through the Naval Supply Systems Command (NAVSUP) Weapon Systems Support, is soliciting proposals for the repair of one AVSS System Control, identified by part number 901-005-980-111 and NIIN 015293717. This procurement is classified as a sole source requirement, indicating that the government lacks sufficient data to contract with any source other than the current approved supplier, necessitating Government Source Approval prior to award. The AVSS System Control is critical for maintaining operational readiness in naval aviation, and interested vendors must submit the required documentation as outlined in the NAVSUP WSS Source Approval Brochure to be considered. Proposals must remain valid for a minimum of 120 days, and inquiries can be directed to Marisa L. Tetkowski at Marisa.Tetkowski@navy.mil.
