Development and design

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]
