This pre-solicitation notice is for a planned five-year requirements contract, but it is a notice of intent rather than a request for competitive proposals, and the Government will not award a contract based on this posting. All responsible sources may submit a capability statement, proposal, or quotation and must be registered in SAM and meet FAR 9.104 responsibility criteria. Technical data packages are associated with the requirement, and the solicitation will be issued electronically with no bidder mailing list, so interested parties must monitor for amendments. The solicitation will not be available for at least 15 business days after this synopsis, and vendors should not contact ACC-DTA seeking it. Any future RFP contents will take precedence over this pre-solicitation synopsis.
