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.^[5] 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.^[6] The cutters are armed mainly to take on lightly-armed hostiles in low-threat environments.

Construction and career

Calhoun and her sister ship Friedman were ordered on 21 December 2018. On 12 November 2019, 100 tons of her steel had been cut.^[7] As of July 2021, she was more than halfway through her construction schedule. After the planned ceremony was delayed in 2020, her keel was formally authenticated on 23 July 2021.^[8][9] Calhoun was launched on 2 April 2022 and christened on 4 June 2022.^[10][11] Ingalls Shipbuilding announced on August 2, 2023 that Calhoun completed its acceptance sea trials.^[12] The Calhoun was delivered to Coast Guard Base Charleston and commissioned on April 20, 2024. ^[13]
