This is a sole-source Navy requirement for newly manufactured spare parts because the Government lacks sufficient, accurate, or legible data to contract with another source. Items require Government Source Approval prior to award; non-approved sources must submit the information required by the NAVSUP WSS Source Approval Brochure with their proposal or their offer will not be considered. Proposals must remain valid for at least 120 days following submission. Contractual documents are considered issued when mailed, faxed, or sent electronically, and Government acceptance of a proposal constitutes bilateral agreement to that issuance. For questions, contact Katlyn Galetto at Katlyn.m.galetto.civ@us.navy.mil.
