Development and design
Main article: Legend-class cutter

All of Legend-class cutters were constructed by Huntington Ingalls Industries and were part of the Integrated Deepwater System Program.[4] They are of the high endurance cutter roles with additional upgrades to make it more of an asset to the Department of Defense during declared national emergency contingencies.[5] The cutters are armed mainly to take on lightly-armed hostiles in low-threat environments.
