September 29, 1989 USS Pennsylvania ran aground as it entered the channel during its first visit to Port Canaveral, Florida. Tugboats freed the submarine in about two hours. A Navy investigation determined that Pennsylvania was properly positioned in the channel, but the channel had been silted by the recent passing of Hurricane Hugo.

October 17, 2002 USS Pennsylvania (Gold) pulled to new homeport of Bangor, Washington, after about 80 days transit from Naval Submarine Base Kings Bay, Ga. SSBN 735 is the first Trident submarine to change homeports to Bangor in more than 15 years. She is the first of two boats to come to Bangor from the East Coast with D-5 capabilities.

July 20, 2005 The Ohio-class fleet ballistic-missile submarine USS Pennsylvania, commanded by Cmdr. Dave Knapp (Gold), returned to Naval Base Kitsap after completing its 50th Patrol at sea.

July 25, SSBN 735 was recognized as the U.S. Navy’s best Trident submarine when it was presented the 2004 U.S. Strategic Command Omaha Trophy. The annual award is given to three operational units, recognizing their outstanding contributions to USSTRATCOM’s diverse mission of strategic deterrence. The three competitive categories are Intercontinental Ballistic Missile Command, a Submarine Ballistic Missile Command, and the original Strategic Aircraft Command.

September 26, 2008 The blue crew of USS Pennsylvania, commanded by Cmdr. Brad Neff, recently returned from the ship's 60th Strategic Deterrent Patrol.
