On January 29, 1970, while making a surface run into port in thick fog,
Nathanael Greene ran aground in about 16 feet of water. She was refloated after about 7 hours. On August 11, 1984,
Nathanael Greene lost her propeller in the Irish Sea. While proceeding back to
Holy Loch at about 3 knots using her secondary propulsion motor, a transit of about 5 or 6 days, she was redirected to
Her Majesty's Naval Base, Clyde at
Faslane as the U.S. dry dock in Holy Loch was fully committed and unavailable, while
Admiralty Floating Dock No. 60 at Faslane was available. While in the Faslane dry dock, a fire occurred in one of the dock's enclosed machinery spaces on 18 August 1984. The fire was quickly extinguished and did not affect the
Greene. While in dry dock, it was established that the main shaft had broken with the loss of about a third of its length along with the propeller. Repairs were completed in about 12 days with the
Nathanael Green undocked on 3 September 1984. On 13 March 1986
Nathanael Greene ran aground in the
Irish Sea, suffering severe damage to her
rudder and
ballast tanks. Her grounding was a serious accident involving a U.S. Navy nuclear-powered ballistic missile submarine. She was deactivated while still in commission in May 1987. Her early deactivation was decided both as a result of the damage sustained in the accident as well as in accordance with the limitations set by the
SALT II treaty. ==Decommissioning and disposal==
