USS John C. Butler (DE-339) was the lead ship of her class of destroyer escorts in the service with the United States Navy from 1944 to 1946. She was recommissioned between 1950 and 1957 and finally sunk as a target in 1971.
The names of commissioned ships of the United States Navy all start with USS, for United States Ship. Non-commissioned, primarily civilian-crewed vessels of the U.S. Navy under the Military Sealift Command have names that begin with USNS, standing for United States Naval Ship. A letter-based hull classification symbol is used to designate a vessel's type. The names of ships are selected by the Secretary of the Navy. The names are those of states, cities, towns, important persons, important locations, famous battles, fish, and ideals. Usually, different types of ships have names originated from different types of sources.
The Suffren class is a class of nuclear attack submarines, designed by the French shipbuilder Naval Group for the French Navy. It is intended to replace the Rubis-class submarines. Construction began in 2007 and the first unit was commissioned on 6 November 2020. The lead boat of the class, Suffren, entered service on 3 June 2022.
The Rubis class is a class of nuclear-powered attack submarines operated by the French Navy. It comprises six boats, the first entering service in 1983 and the last in 1993. Two additional units originally planned were cancelled as a result of post-Cold War budget cuts. All six submarines of the Rubis class are based at Toulon and are part of the Escadrille de sous-marins nucléaires d'attaque. Smaller than contemporary designs of other major world navies, the Rubis class shares many of its system designs with the conventionally-powered Agosta class. In the late 1980s, the Rubis class was proposed to Canada in the context of their plan to acquire nuclear-powered submarines.
Le Rubis, initially named Provence, was a first-generation nuclear attack submarine and lead boat of the Rubis class of the French Navy, assigned to the attack nuclear submarine squadron.

The boat's name is a pun on a precious stone (Amethyst) and the acronym AMElioration Tactique, HydrodYnamique, Silence, Transmission, Ecoute. The boat is a major upgrade upon the initial design of the Rubis type, and earlier units have since been refitted to meet her standards.

USS Hissem (DE-400/DER-400) was an Edsall class destroyer escort of the United States Navy. Hissem was constructed in 1943 as DE-400. In 1955, the vessel was equipped with modern radars, and the designation was changed to DER-400. The special purpose of DER ships was the detection of aircraft. Their chief role was to extend the DEW line out into the N. Atlantic and the N. Pacific oceans.
