U.S. Navy’s Virginia-Class Submarine ‘Montana’ Clears Initial Sea Trials

Huntington Ingalls has announced that the U.S. Navy’s fast-attack submarine Montana (SSN 794) completed initial sea trials.

The Virginia-class submarine, built at HII’s Newport News Shipbuilding division, spent several days at sea to test the ship's systems and components.

Testing included submerging the submarine for the first time and high-speed maneuvers while on the surface and submerged. HII teams will continue the testing program and will deliver the boat to the U.S. Navy later this year.

Construction of Montana began in 2015. The boat — the 21st Virginia-class submarine built as part of the teaming partnership with General Dynamics' Electric Boat — was christened in September 2020.
