Type VII submarineType VII U-boats were the most common type of German World War II U-boat. 703 boats were built by the end of the war. The lone surviving example, , is on display at the Laboe Naval Memorial located in Laboe, Schleswig-Holstein, Germany. The Type VII was based on earlier German submarine designs going back to the World War I Type UB III and especially the cancelled Type UG. The type UG was designed through the Dutch dummy company NV Ingenieurskantoor voor Scheepsbouw Den Haag (I.v.
Battle of the River PlateThe Battle of the River Plate was fought in the South Atlantic on 13 December 1939 as the first naval battle of the Second World War. The Kriegsmarine heavy cruiser , commanded by Captain Hans Langsdorff, engaged a Royal Navy squadron, commanded by Commodore Henry Harwood, comprising the light cruisers , (on loan to the New Zealand Division) and the heavy cruiser . Graf Spee had sailed into the South Atlantic in August 1939, before the war began, and had begun commerce raiding after receiving the appropriate authorisation on 26 September 1939.
Seaplane tenderA seaplane tender is a boat or ship that supports the operation of seaplanes. Some of these vessels, known as seaplane carriers, could not only carry seaplanes but also provided all the facilities needed for their operation; these ships are regarded by some as the first aircraft carriers and appeared just before the First World War. In maritime parlance a tender is a vessel that is used to support the operation of other vessels. In British usage, the term tender was used for small craft, with the term depot ship being used for large seagoing vessels.
Midget submarineA midget submarine is any submarine under 150 tons, typically operated by a crew of one or two but sometimes up to six or nine, with little or no on-board living accommodation. They normally work with mother ships, from which they are launched and recovered and which provide living accommodation for the crew and support staff. Both military and civilian midget submarines have been built. Military types work with surface ships and other submarines as mother ships.
E-boatE-boat was the Western Allies' designation for the fast attack craft (German: Schnellboot, or S-Boot, meaning "fast boat"; plural Schnellboote) of the Kriegsmarine during World War II; E-boat could refer to a patrol craft from an armed motorboat to a large Torpedoboot. The name of E-boats was a British designation using the letter E for Enemy, The main wartime production boats, designated the S100 class, were very seaworthy, heavily armed and capable of sustaining , briefly accelerating to .
Consolidated PBY CatalinaThe Consolidated Model 28, more commonly known as the PBY Catalina (US Navy designation), is a flying boat and amphibious aircraft that was produced in the 1930s and 1940s. In Canadian service it was known as the Canso. It was one of the most widely used seaplanes of World War II. Catalinas served with every branch of the United States Armed Forces and in the air forces and navies of many other nations. The last military PBYs served until the 1980s.
Royal Netherlands NavyThe Royal Netherlands Navy (Koninklijke Marine) is the naval force of the Kingdom of the Netherlands. It is one of the four Netherlands Armed Forces. It was founded on 8 January 1488, making it the third oldest naval force in the world. During the 17th century, the navy of the Dutch Republic (1581–1795) was one of the most powerful naval forces in the world and played an active role in the Anglo-Dutch Wars, the Franco-Dutch War, and wars against Spain and several other European powers.
German rearmamentGerman rearmament (Aufrüstung, ˈaʊ̯fˌʀʏstʊŋ) was a policy and practice of rearmament carried out by Germany from 1918 to 1939, in violation of the Treaty of Versailles which required German disarmament after WWI to prevent it starting another war. It began on a small, secret, and informal basis shortly after the treaty was signed, but was openly and massively expanded after the Nazi Party came to power in 1933.
MinesweeperA minesweeper is a small warship designed to remove or detonate naval mines. Using various mechanisms intended to counter the threat posed by naval mines, minesweepers keep waterways clear for safe shipping. The earliest known usage of the naval mine dates to the Ming dynasty. Dedicated minesweepers, however, only appeared many centuries later during the Crimean War, when they were deployed by the British. The Crimean War minesweepers were rowboats trailing grapnels to snag mines.
Coastal defence shipCoastal defence ships (sometimes called coastal battleships or coast defence ships) were warships built for the purpose of coastal defence, mostly during the period from 1860 to 1920. They were small, often cruiser-sized warships that sacrificed speed and range for armour and armament. They were usually attractive to nations that either could not afford full-sized battleships or could be satisfied by specially designed shallow-draft vessels capable of littoral operations close to their own shores.
