history

SSN-690 was commissioned in 1971 and laid down as the first unit of the class at Electric Boat in August 1972 . Construction took just over two years, and the boat was launched in October 1974. After nearly three years of final equipment and test drives, the Philadelphia entered service in June 1977.

By 1991 the Philadelphia made six missions, then took part in Operation Desert Storm . Another seven relocations followed by 2005, all of them in the North Atlantic, the Persian Gulf or the Mediterranean. In 1999 the boat was docked and modified so that it can carry a dry deck shelter . In 2003, the Philadelphia became the first Los Angeles class unit to achieve 1,000 dives.

On the last mission in 2005, on September 5, the Philadelphia rammed the cargo ship M / V Yaso Aysen , which was sailing under the Turkish flag . The collision, which took place 30 miles off the coast of Bahrain , was only light, there were no injuries. The submarine suffered only superficial damage, the hull damage of the freighter was also checked by the United States Coast Guard and the ship was then declared seaworthy. In 2007, the Philadelphia then moved with four Arleigh Burke class destroyers and the cruiser USS Gettysburg (CG-64) as escort for the carrier USS Enterprise (CVN-65) as part of the fight against terrorism. In July 2009, the Philadelphia moved for the last six months in the Atlantic.

On June 25, 2010, on the 33rd anniversary of the commissioning, the Philadelphia was decommissioned. Disassembly then began in the Norfolk Naval Shipyard and the nuclear propulsion system is disposed of in the Ship-Submarine Recycling Program in the Puget Sound Naval Shipyard .

In fiction

The Philadelphia played a bigger role in the seventh episode of the television series Navy CIS .
