This is a sole-source repair requirement for one generator/alternator (NSN 7R 6115 011149696; part number 70550-02031-111), a Critical Safety Item under NAICS 335312. NAVSUP WSS intends to award under an existing BOA because the Government lacks sufficient, accurate, or legible data to contract with another source. The item is subject to Free Trade Agreements and the WTO Government Procurement Agreement. Government source approval is required prior to award, and new-source approval normally cannot be completed without delaying award. Non-approved sources must submit the information required by the NAVSUP WSS Source Approval Brochure with their proposal; incomplete submissions will not be considered.
