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 docking team executed superbly, setting the project team up for a safe and successful start."
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 modernization.
