The fourth ship of the United States Navy to be named for the Commonwealth of Pennsylvania (1837 140-gun ship of the line, 1863 screw steamer, 1903 armored cruiser, and the famous BB-38 of the World Wars), SSBN-735 was commissioned in 1989 and is home ported at Bangor.
She just completed her Engineered Refueling Overhaul (ERO) at Puget Sound Naval Shipyard in 2012 and is expected to serve well into the 2030s at which point she will be pushing a half-century with the dolphins.
