6/7/2012 Shipyard Begins First Virginia-class EDSRA
from : Pearl Harbor Naval Shipyard Public Affairs

PEARL HARBOR -- USS Texas (SSN 775) entered dry dock at Pearl Harbor Naval Shipyard (PHNSY) May 31, marking the beginning of the first major maintenance period of a Virginia-class submarine at the shipyard.

The shipyard will conduct an Extended Dry-docking Selected Restricted Availability (EDSRA) on Texas. The EDSRA is a nearly two-year-long project that requires placing the submarine in dry dock to perform maintenance and modernization on certain shipboard systems.

"This represents a new chapter for Pearl Harbor Naval Shipyard's legacy," said Capt. Brian Osgood, PHNSY shipyard commander.

Adding to the complexity and magnitude of the availability is the fact that Texas is a Virginia-class submarine. This means workers will be executing many jobs in the work package for the first time. For example, the propulsor installation marks only the second effort by a public shipyard.

While the EDSRA is the first of its kind for the shipyard, workers have gained valuable experience on Virginia-class submarines through previous short-term availabilities at Pearl Harbor or assignments at other public and private shipyards. The shipyard has already dry-docked Virginia-class submarines three times, although not in the dry dock where the EDSRA is scheduled.

The shipyard began preparing for Virginia-class submarines in 2005. These preparations included ensuring facilities, tooling, other equipment, instructions, material, and trained personnel were ready and available to support the Navy's newest class of attack submarines.

USS Hawaii (SSN 776) arrived at her new homeport in the islands in July 2009. Texas was next in November of that year. USS North Carolina (SSN 777) followed in November 2010, becoming the third Virginia-class submarine homeported at Pearl Harbor.

"The Texas EDSRA puts us on the path to be the Virginia-class center of excellence," said Osgood.  "With the focus on the Asia Pacific region and Pearl Harbor Naval Shipyard's strategic location, we are well poised for the next chapter of our history of keeping Pacific Fleet ships fit to fight."

The Virginia-class is the Navy's latest generation of attack submarines, measuring 377 feet long, weighing 7,800 tons when submerged and with a complement of more than 130 crewmembers.

These state-of-the-art submarines are capable of supporting a multitude of missions, including anti-submarine warfare, anti-surface ship warfare, strike, naval special warfare involving special operations forces, intelligence, surveillance, and reconnaissance, irregular warfare, and mine warfare.
