Virginia-class fast-attack submarine USS Colorado (SSN 788) completed a scheduled maintenance period at Pearl Harbor Naval Shipyard and Intermediate Maintenance Facility (PHNSY & IMF) 29 days ahead of schedule, June 10, 2026.
Maintenance was completed early through a close partnership between the shipyard and Colorado’s crew. A shared focus between the shipyard workforce and the crew drove the project to an early completion, according to the officials.
“Finishing ahead of schedule is not about rushing, it’s about hard work and persistence,” said US Navy Capt. Ryan McCrillis , commander of PHNSY & IMF.
“It’s producing first-time, high-quality work and attacking every roadblock with urgency. It’s a team effort, from the newest apprentice to senior shipyard leaders, the ship’s force, the project team, and support from the fleet and headquarters.”
For Colorado’s crew, the accelerated shipyard period required active involvement and constant coordination with shipyard maintainers. By applying their deep system knowledge alongside PHNSY & IMF’s experts, the crew played a crucial role in early completion, ensuring the submarine returned to the fleet fully ready for operations.
Commissioned March 17, 2018, at Naval Submarine Base New London, USS Colorado is the 15th Virginia-class fast-attack submarine and fifth Block III submarine of the class.
The vessel is assigned to Submarine Squadron 7 and is capable of supporting various missions, including anti-submarine warfare, anti-surface ship warfare, strike warfare, special operations forces support, and intelligence, surveillance, and reconnaissance.
