To accelerate the design, development and demonstration of MUSV capabilities, the Navy will be utilizing the Other Transaction Authority pathway as outlined in Title 10 U.S.C. § 4022. It is intended that this solicitation will result in the award(s) of prototype project(s), which may include commercially available technologies fueled by commercial or strategic investment that can incrementally improve commercial technologies, existing Government-owned capabilities, or concepts for defense application.

The initial effort, as solicited in this notice, will focus on offerors who can perform and successfully complete an MUSV autonomy and vessel performance test. The Solicitation Guidance provides information on how to respond to this solicitation and the guidelines for proposals. The following attachments to this notice are included below:
