This is a market research notice for a potential future procurement of three Transmitter Subassemblies, with an estimated delivery schedule of 14 months after order receipt to destination SW3215. The government is currently exploring if other capable sources or commercial items exist, as it presently believes the supplies are available from only a limited number of sources. It is not expected to be set aside for small businesses, but subcontracting opportunities may exist with two identified firms. Interested parties may identify their capability to provide a commercial item within 15 days of this notice. This is not a solicitation, and the government does not intend to contract or pay for information based on this request.
