The contract to build Pittsburgh was awarded to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut on 16 April 1979, and her keel was laid down on 15 April 1983. She was launched on 8 December 1984 and commissioned on 23 November 1985.
On 25 February 2019, Pittsburgh returned to her homeport at Naval Submarine Base New London after completion of her final deployment. The submarine then arrived at Bremerton, Washington on 28 May 2019, for a months-long inactivation and decommissioning process.
Pittsburgh was officially inactivated on 17 January 2020 at the Undersea Warfare Museum in Keyport, Washington, and awaited the Submarine Recycling Program at Puget Sound Naval Shipyard in Bremerton, Washington. She was later decommissioned 15 April 2020 and crew released, 37 years to the day of her keel laid down.
