ASTM Committee F41 on Unmanned Maritime Vehicle Systems (UMVS) was formed in 2005. F41 meets once each year, with approximately 50 members attending two days of technical meetings; it is often in conjunction with the Unmanned Systems North America Conference of AUVSI. This Committee addresses issues related to standards development for unmanned undersea vehicle (UUV) systems and unmanned surface vehicle (USV) systems to facilitate an interoperable, modular, and multi-functional family of platforms. Stakeholders include manufactures of UMVS and their components, federal agencies, design professionals, professional societies, maintenance professionals, trade associations, financial organizations, and academia. The Committee, with a membership of approximately 165, currently has its standards published in the Annual Book of ASTM Standards, Volume 15.11. F41 has 5 technical subcommittees that maintain jurisdiction over these standards. Information on this subcommittee structure and F41's portfolio of approved standards and Work Items under construction are available from the List of Subcommittees, Standards and Work Items below.
