The command’s role has been to provide anti-submarine warfare and ocean borne acoustic information to tactical platforms and shore-based facilities, providing a link between U.S. and U.K. maritime forces and their headquarters. With its unique combination of professionals from a broad spectrum of countries and disciplines, JMF accomplishes a wide variety of mission oriented goals.
