Modular Attack Surface Craft (MASC)- Solicitation

The Navy is pleased to announce the Modular Attack Surface Craft (MASC) program, which seeks Unmanned Surface Vessels (USV) to address several key operational needs. MASC seeks to leverage cutting-edge technologies and modular design principles to create adaptable and resilient solutions that can effectively counter evolving threats.

We invite interested parties with expertise in innovative solutions to complex problems, vessel construction, autonomy, perception systems and general maritime experience to participate in this exciting opportunity.

To accelerate the design, development and demonstration of MASC 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 projects, which may include not only commercially-available technologies fueled by commercial or strategic investment, but also concept demonstrations, pilots, and agile development activities that can incrementally improve commercial technologies, existing Government-owned capabilities, or concepts for defense application.

The initial effort will focus on the relevance, technical merit, feasibility, and affordability of the proposed vessel solutions. The Solicitation Guidance provides information on how to respond to this solicitation and outlines the phased approach. Exhibit A, the Area of Interest (AOI) outlines the technical desired attributes and technology capabilities the Navy is seeking from industry for the MASC program.
