The US Navy's Portsmouth Naval Shipyard (PNSY) has drydocked the Los Angeles-class attack submarine, USS Annapolis (SSN 760), for maintenance work and several system upgrades.
The new development is part of a planned 23-month long engineering overhaul of the submarine.
Shipyard commander captain William Greene said: "Every docking is a precise evolution with exacting standards.
"The docking team executed superbly, setting the project team up for a safe and successful start to the availability."
Prior to the drydocking, the shipyard formed a project planning team, including personnel from engineering and production departments, which developed a detailed maintenance availability plan.
Project superintendent Scott Kimmel said: "A lot of time was spent to ensure success before Annapolis' arrival.
"Now that Annapolis is here, the 'a-team,' along with the ship's crew, are excited and poised to succeed and complete her engineered overhaul."
The Los Angeles-class submarine is designed to conduct anti-submarine warfare, intelligence gathering, show-of-force missions, insertion of special forces, strike missions, mining and search and rescue.
The first submarine of this class was commissioned in 1976. The latest version, USS Cheyenne, was commissioned in 1996.
Currently, the US Navy has 51 nuclear powered Los Angeles-class submarines, 16 in the Pacific Fleet and 32 in the Atlantic Fleet.
PNS is one of four remaining naval shipyards in the US, which is capable of performing attack submarine overhaul, repair, and modernisation.

PNSY Safely Docks USS Annapolis for Overhaul
From Portsmouth Naval Shipyard Public Affairs
KITTERY, Maine (NNS) -- Portsmouth Naval Shipyard (PNSY) workers safely drydocked USS Annapolis (SSN 760) June 15 for planned maintenance work and several system upgrades.
Annapolis arrived at PNSY April 25, and the dry-docking of the submarine is part of a greater engineering overhaul scheduled to last 23 months.
"A lot of time was spent to ensure success before Annapolis' arrival," said Project Superintendent Scott Kimmel. "Now that Annapolis is here, the 'A-Team,' along with the ship's crew, are excited and poised to succeed and complete her engineered overhaul."
More than a year prior to Annapolis' arrival, the shipyard assembled a project planning team comprised of individuals from engineering and production departments. The team developed a detailed plan for this maintenance availability to ensure a successful overhaul for Annapolis and the shipyard.
"Every docking is a precise evolution with exacting standards," said Shipyard Commander Capt. William Greene. "The docking team executed superbly, setting the project team up for a safe and successful start to the availability."
Attack submarines like Annapolis have multi-faceted missions. They use their stealth, persistence, agility, and firepower to deploy and support special force operations, disrupt and destroy an adversary's military and economic operations at sea, provide early strike from close proximity, and ensure undersea superiority.
Portsmouth Naval Shipyard is the Navy's center of excellence for attack submarine overhaul, repair and modernization. As a field activity of NAVSEA, PNSY is committed to maximizing the material readiness of the fleet by continuing to safely deliver first-time quality work, on time and on budget.
