what does ss stand for on naval ships
Single-screw Steamship
title: Steamship text: Steamship A steamship, often referred to as a steamer, is a type of steam powered vessel, typically ocean-faring and seaworthy, that is propelled by one or more steam engines that typically move (turn) propellers or paddlewheels. The first steamships came into practical usage during the early 1800s; however, there were exceptions that came before. Steamships usually use the prefix designations of "PS" for "paddle steamer" or "SS" for "screw steamer" (using a propeller or screw). As paddle steamers became less common, "SS" is assumed by many to stand for "steam ship". Ships powered by internal combustion engines use a prefix title: SSN (hull classification symbol) text: SSN (hull classification symbol) An SSN is a nuclear-powered general-purpose attack submarine. "SSN" is the US Navy hull classification symbol for such vessels; the "SS" denotes a submarine and the "N" denotes nuclear power. The designation SSN is used for interoperability throughout NATO under STANAG 1166. though navies use other terms. The first nuclear-powered attack submarine was the US Navy's , operational from 1954. This was followed by the four submarines of the entering service in 1957. The Royal Navy's first nuclear fleet submarine was which by using an American reactor entered service in 1963. The first all-British nuclear submarines title: SSN (hull classification symbol) text: decommissioned nuclear submarines require costly dismantling and long term storage of the radioactive waste. The following navies currently operate SSNs: Known as "fleet submarines" in the Royal Navy SSN (hull classification symbol) An SSN is a nuclear-powered general-purpose attack submarine.

The term "steamer" is occasionally used, out of nostalgia, for diesel motor-driven vessels, prefixed "MV". Steam can be generated with the use of heat produced by nuclear fission within a nuclear reactor. Systems that incorporate nuclear components are found almost mostly onboard military vessels due to title: United States Navy ships text: United States Navy ships The names of commissioned ships of the United States Navy all start with USS, for "United States Ship". Non-commissioned, primarily civilian-manned 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
