This is a solicitation for newly manufactured spare parts, with a required delivery of 3 units within 90 days. The work involves Foreign Military Sales (FMS) delivery, with shipping instructions to a domestic U.S. freight forwarder under contract by the FMS customer. Offers from sources not on the government-approved source list will be deemed technically unacceptable, and any distributors must provide an authorized distributor letter at the time of proposal submission. The procurement is issued under emergency acquisition authority, waiving standard synopsis requirements. Specific clauses related to Item Unique Identification are waived for the non-CLSSA FMS portion of this procurement, as the assets will never be owned by the U.S. government.
