Pittsburgh IV (SSN-720)

1985–2019

The fourth U.S. Navy ship named for the industrial city in western Pennsylvania. The first Pittsburgh (often spelled Pittsburg), a sidewheel, ironclad gunboat, served from 1862–1865. The second Pittsburgh (Armored Cruiser No. 4) was laid down as Pennsylvania on 7 August 1901, renamed Pittsburgh on 27 August 1912 to free the name Pennsylvania for a new battleship, and served from 1905–1931. Heavy cruiser Pittsburgh (CA-70) was renamed Canberra on 12 October 1942, but the name Pittsburgh was assigned to another heavy cruiser (CA-72), that had originally been named Albany. The third Pittsburgh served (with a brief interruption) from 1944–1973.

Pittsburgh, Cmdr. Charles H. Griffiths Jr. in command, deployed (8 November 1990–28 February 1991) for Operation Desert Storm (the liberation of the Kuwaitis from the Iraqis) and she fired UGM-109 Tomahawk Land Attack Missiles (TLAMs) against Iraqi military targets.

Pittsburgh, Cmdr. Jeffrey S. Currer in command, deployed for Operation Iraqi Freedom I (1 October 2002–27 April 2003) and on 21 and 22 March she joined 29 other U.S. and British ships and submarines that fired TLAMs against Iraqi military targets. Currer later received the Bronze Star for his “extraordinary leadership and operational skills” during these battles.

Pittsburgh, Cmdr. Jason Deicher in command, returned to her home port of Naval Submarine Base New London, Conn., from her final deployment on 25 February 2019. The crowd that greeted Pittsburgh upon her return included Dr. Sawyer, the boat’s sponsor. The veteran attack submarine turned her prow northward and passed below the Arctic ice on her final voyage and, on 28 May 2019, slipped into Naval Base Kitsap-Bremerton, Wash., and began her inactivation process. The Navy removed Pittsburgh from its inventory and began her inactivation availability on 6 August 2019.

Detailed history pending.
