Alfred von TirpitzAlfred Peter Friedrich von Tirpitz (ˈalfʁeːt fɔn ˈtɪʁpɪt͡s; 19 March 1849 – 6 March 1930) was a German grand admiral, Secretary of State of the German Imperial Naval Office, the powerful administrative branch of the German Imperial Navy from 1897 until 1916. Prussia never had a major navy, nor did the other German states before the German Empire was formed in 1871. Tirpitz took the modest Imperial Navy and, starting in the 1890s, turned it into a world-class force that could threaten Britain's Royal Navy.
TorpedoA modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a fish. The term torpedo originally applied to a variety of devices, most of which would today be called mines. From about 1900, torpedo has been used strictly to designate a self-propelled underwater explosive device.
United StatesThe United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America and consisting of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations.
DestroyerIn naval terminology, a destroyer is a fast, maneuverable, long-endurance warship intended to escort larger vessels in a fleet, convoy, or battle group and defend them against powerful short-range attackers. They were originally developed in 1885 by Fernando Villaamil for the Spanish Navy as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats".
Norwegian campaignThe Norwegian campaign (8 April - 10 June 1940) involved the attempt by Allied forces to defend northern Norway coupled with the resistance of the Norwegian military to the country's invasion by Nazi Germany in World War II. Planned as Operation Wilfred and Plan R 4, while the German attack was feared but had not yet happened, the battlecruiser set out from Scapa Flow for the Vestfjorden with twelve destroyers on 4 April. The Royal Navy and the Kriegsmarine met at the First Battle of Narvik on 9 and 10 April, and British forces conducted the Åndalsnes landings on 13 April.
FrigateA frigate (ˈfrɪɡət) is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied somewhat. The name frigate in the 17th to early 18th centuries was given to any full-rigged ship built for speed and manoeuverability, intended to be used in scouting, escort and patrol roles. The term was applied loosely to ships varying greatly in design. In the second quarter of the 18th century, the 'true frigate' was developed in France.
Alaska-class cruiserThe Alaska class were six very large cruisers ordered before World War II for the United States Navy, of which only two were completed and saw service late in the war. The US Navy designation for the ships of this class was 'large cruiser' (CB) and the majority of leading reference works consider them as such. However, various other works have alternately described these ships as battlecruisers despite the US Navy having never classified them as such.
