The USS Portsmouth (SSN-707) was a nuclear-powered submarine of the United States Navy and belonged to the Los Angeles-class submarine to.
history
construction
The Portsmouth was built by Electric Boat in Groton , Connecticut , and named by Helen Poe Goodrich after the cities of the same name in New Hampshire and Virginia .
Calls
Just three weeks after entering service with the US Navy, it was already participating in the US invasion of Grenada . Only then, from August 1984, the Portsmouth went through a 14-week test phase and moved to its new home port in San Diego . From there, the submarine took part in six mission trips to the western Pacific ( WestPac ).
In February 1991 the Portsmouth underwent an overhaul of its weapon systems and propulsion system. The next mission took place in 1993 again from San Diego, among other things, the ship tested the use of Army Rangers from submarines as well as new sonar systems in a so-called Joint Exercise .
In 1995 and 1996, the Portsmouth took part in the guarding of the Republic of China (Taiwan) with the aircraft carrier combat group around the USS Nimitz (CVN-68) after the People's Republic of China had carried out missile tests in the Formosa Strait . In 1997, she was the first American warship to make a friendship visit to the port of Hong Kong, which was reunified with China .
The Portsmouth was last deployed from the end of 2003 to February 2004, when it took part in the Exercise Northern Edge exercise in the Gulf of Alaska .
The Portsmouth was officially decommissioned on September 10, 2004. This happened after 21 years of service and only half of the planned service time. The reasons for this are to be found in the fact that the ship belonged to the first construction lot of its class and therefore (due to the lack of a vertical launching system ) only had limited capacities for land attacks. In addition, the ship's nuclear fuel should have been replaced; the Navy was able to avoid these costs by decommissioning. The ship, now known as ex-Portsmouth , is waiting for the Ship-Submarine Recycling Program to begin; dismantling is scheduled to begin in 2011.
