The Suribachi-class ammunition ships was a class of two auxiliary vessels of the United States Navy in service from 1956 to 1995. They were among the first specialized underway replenishment ships built after World War II. The Nitro-class ammunition ships are sometimes considered part of this class. Both ships were decommissioned in the mid-1990s and were struck from the Naval Vessel Register in 1996. Both vessels were discarded in the 2000s.

The Ship Characteristics Board was a unit of the United States Navy.
