USS Pinnacle (AM-462/MSO-462) was an Aggressive-class minesweeper acquired by the U.S. Navy for the task of removing mines that had been placed in the water to prevent the safe passage of ships.

Sailing east on 4 September, she visited the United Kingdom and the Netherlands, took part in NATO maneuvers in the North Sea then operated with the U.S. 6th Fleet in the Mediterranean from 20 October to 21 January 1957.

As tension in the Middle East rose to a new height, Pinnacle steamed directly to the eastern Mediterranean and for most of that deployment cruised off the Levantine states.

Returning in June, she resumed a series of local operations Mine Warfare school ship duties and amphibious exercise in the Caribbean.
