MISSION STATEMENT

The mission of the Naval Anti-Submarine Combatant Craft (NASCC) is to provide effective anti-submarine warfare (ASW) capabilities to foreign naval surface forces. Supported by a fast and highly-maneuverable hull-form designed for year-round operations, this torpedo boat will feature an advanced SONAR suite, offensive ASW technologies, and the capacity to support small-scale maritime interdiction operations. This vessel is designed for diverse, short-endurance missions in various high-traffic littoral and coastal regions around the world and specific foreign ports.
