Template:Infobox ship imageTemplate:Infobox ship class overviewTemplate:Infobox ship characteristics

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 Template:Sclasss 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.

Description

The Suribachi class were the first ammunition ships specifically designed for underway replenishment for the United States Navy.Template:Sfn The Suribachi class were designed by the Ship Characteristics Board as SCB 114.Template:Sfn The ships had elevators installed to ease the internal handling of ammunition and explosives.Template:Sfn Additionally as part of a refit in 1960s under SCB 232, the class had three holds converted to store missiles and were given high speed transfer systems for replenishment at sea.Template:Sfn

The two ships had a light displacement of Template:Convert, a standard displacement of Template:Cvt and displaced Template:Cvt at full load. They measured Template:DWT, Template:Convert long overall with a beam of Template:Cvt and a draft of Template:Cvt.Template:Sfn The vessels were powered by steam created by two Combustion Engineering boilers capable of Template:Cvt at Template:Cvt powering two Bethlehem geared turbines turning one propeller creating Template:Convert.Template:Sfn This gave the ships a maximum speed of Template:Convert,Template:Sfn but this later declined to Template:Convert.Template:Sfn

The Suribachi class were initially armed with four twin-mounted 3"/50 caliber guns placed in superfiring positions fore and aft.Template:SfnTemplate:Sfn However, in the 1960s, the two aft mounts were removed and a landing pad for helicopters was installed in place.Template:SfnTemplate:Efn The vessels mounted SPS-10 surface search radar and two Mk 36 SRBOC six-barrelled chaff launchers for electronic defense.Template:Sfn They also had SPS-6 radar and Mark 63 Gun Fire Control System which were removed in 1977–1978.Template:Sfn The vessels had a complement of 312 sailors including 18 officers.Template:Sfn

Two new purpose-built ammunition ships were authorized in 1954.Template:Sfn As ammunition ships, the two vessels carry the names of volcanoes.Template:Sfn The two vessels were constructed by the Bethlehem Steel Corporation at the Bethlehem Sparrows Point Shipyard in Maryland.Template:Sfn Suribachi entered service in 1956, followed by Mauna Kea in 1957. The Template:Sclasss are often considered part of this class, but were built to an altered design.Template:SfnTemplate:Sfn Mauna Kea was transferred to the reserve fleet in 1979. However, due to high operational requirements, Mauna Kea rejoined the active fleet in 1982.Template:Sfn In 1986 Mauna Kea conducted trials using portable rails for the deployment of naval mines.Template:Sfn

Suribachi was decommissioned in 1994, followed by Mauna Kea in 1995. Both ships were stricken from the Naval Vessel Register on 12 December 1996.Template:Sfn Mauna Kea was used as target practice in fleet exercise in 2006, and Suribachi was scrapped at Brownsville, Texas in mid 2009.
