The Navy’s Criminal Investigative Service is seeking information regarding the destruction of government property aboard the nuclear attack submarine USS Texas on or about March 29th while the boat was at the Portsmouth Naval Shipyard in Kittery, Maine.

USS Texas (SSN 775) is a Virginia-class attack submarine commissioned in September 2006.   These vessels are tasked with open ocean and littoral missions.  They were built as a lower-cost version of the Sea Wolf class and replaced the older Los Angeles class at the end of the Cold War.

The Virginia class boats are undergoing a 20-month upgrade program to extend their service life including new computers, sensors, and new bows enclosing a wet sonar array.

The exact nature of the damage to the submarine is unknown and the navy is keeping a lid on information regarding the type of vandalism and the extent of the damage.  We do have information that says an armed security watch is aboard the sub with orders to shoot any unauthorized person who attempts to get aboard. Generally speaking a vessel in dry dock will have a skeleton crew that stands security watches in secure spaces like the reactor compartment working with civilian law enforcement officers at the dockyard.
