USS meaning in Space Science ?

Answer: What is United States Ship mean?

United States Ship (abbreviated as USS or U.S.S.) is a ship prefix used to identify a commissioned ship of the United States Navy and applies to a ship only while it is in commission. Before commissioning, the vessel may be referred to as a "pre-commissioning unit" (PCU), but is officially referred to by name with no prefix. After decommissioning, it is referred to by name with no prefix, though people commonly refer to those ships with the prefix "ex-", as in ex-ship name. In-service but non-commissioned Navy ships go by the prefix USNS, which stands for United States Naval Ship.

From the early beginnings of the U.S. Navy there had been no standard method of referring to U.S. Navy ships until 1907 when President Theodore Roosevelt issued Executive Order 549 on 8 January stating that all U.S. Navy ships were to be referred to as "The name of such vessel, preceded by the words, United States Ship, or the letters U.S.S., and by no other words or letters".

Today's Navy Regulations define the classification and status of naval ships and craft:

The Chief of Naval Operations shall be responsible for ... the assignment of classification for administrative purposes to water-borne craft and the designation of status for each ship and service craft.Commissioned vessels and craft shall be called "United States Ship" or "U.S.S."Civilian manned ships, of the Military Sealift Command or other commands, designated "active status, in service" shall be called "United States Naval Ship" or "U.S.N.S."Ships and service craft designated "active status, in service," except those described by paragraph 3 of this article, shall be referred to by name, when assigned, classification, and hull number (e.g., "HIGH POINT PCH-1" or "YOGN-8").— United States Navy Regulations, 1990, Article 0406. reference
