Naval Engineering

The U.S.S. Olympia is one of the two surviving ships of the era of the vertical reciprocating steam engine. The Cruiser Olympia, launched in 1892, was one of the first naval ships to be built with these engines. As part of the new American steel Navy, the construction of the Olympia was authorized in 1888 as cruiser number 6. As part of a Congressionally-mandated program to establish complete domestic capability for warship construction, the ship's contract was awarded to the Union Iron Works of San Francisco.

The U.S.S. Texas is the last surviving warship of its kind--powered by reciprocating steam engines. It was built during a period in which naval authorities were switching to the newly-developed steam turbine for propulsion, but were unsure of its suitability. Only one more warship, the New York, commissioned one month after the Texas, was to be powered by the reciprocating engines.
