British D-class Submarine
The D-class submarine was the Royal Navy's first class of submarines capable of operating significantly beyond coastal waters. They were also the first boats to be fitted with wireless transmitters. Ten were laid down between 1907 and 1910, though only 8 were completed as D-class boats. The final two hulls were completed as British E-class submarine. Design and description The patrol submarines evolved from the C-class boats. They were designed to be propelled by diesel motors on the surface to avoid the problems with petrol engines experienced with the A class. These boats were designed for foreign service with an endurance of at on the surface and much improved living conditions for a larger crew. D-class boats were fitted with twin screws for greater manoeuvrability and were fitted with saddle tanks. The D class were the first submarines to be equipped with deck guns forward of the conning tower beginning with ''D6''. Also, reserve buoyancy was increased to 20.6%. Armam ...

Vickers Limited
Vickers Limited was a British engineering conglomerate. The business began in Sheffield in 1828 as a steel foundry and became known for its church bells, going on to make shafts and propellers for ships, armour plate and then artillery. Entire large ships, cars, tanks and torpedoes followed. Airships and aircraft were added, and Vickers jet airliners were to remain in production until 1965. Financial problems following the death of the Vickers brothers were resolved in 1927 by separating Metropolitan Carriage Wagon and Finance Company and Metropolitan-Vickers, then merging the remaining bulk of the original business with Armstrong Whitworth to form Vickers-Armstrongs. The Vickers name resurfaced as Vickers plc between 1977 and 1999. History Foundry Vickers was formed in Sheffield as a steel foundry by the miller Edward Vickers and his father-in-law George Naylor in 1828. Naylor was a partner in the foundry Naylor & Sanderson, and Vickers' brother William owned a steel roll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A-class Submarine (1903)
The A class was the Royal Navy's first class of British-designed submarines. Thirteen were built by Vickers at Barrow-in-Furness between 1902 and 1905 as an improvement on the US . Design and construction While there was considerable variation amongst the boats of the class, they were around long and displaced around 200 tons when submerged. The first, ''A1'' (ordered as ''Holland No. 6''), was launched in July 1902, the last, ''A13'', in April 1905. Propulsion All were propelled underwater by battery-powered electric motors and on the surface by shaft-drive Wolseley petrol engines of (''A1''), (''A2-A4'') or (''A5''-''A12''). ''A13'' had an experimental Vickers diesel engine, which proved to be unreliable. Armaments Armament was two torpedo tubes with four torpedoes except for ''A1'', which had 1 tube and 3 torpedoes. Service history This submarine class was plagued by numerous accidents and failures; almost every boat in the class (''A1'', ''A3'', ''A4'', ...

Heligoland Bight
The Heligoland Bight, also known as Helgoland Bight, (german: Helgoländer Bucht) is a bay which forms the southern part of the German Bight, itself a bay of the North Sea, located at the mouth of the Elbe river. The Heligoland Bight extends from the mouth of the Elbe to the islands of Heligoland and lies between the East Frisian island of Wangerooge and the North Frisian peninsula of Eiderstedt. Named after Heligoland, it was the location of World War I naval battles in 1914 and 1917. In 1939 it also had a World War II aerial battle named after it. In the Heligoland Basin (''Helgoländer Becken''), a basin lying directly southwest of Heligoland, the bight is up to deep. One of the busiest shipping lanes in the world, from Hamburg and the mouth of the Elbe to the Straits of Dover and the English Channel, runs through the Heligoland Bight. The area also includes nature reserves such as the ''Heligoland Felssockel'' and the protected Wadden Sea, in which the Wadden Sea Nat ...

The North Sea has featured prominently in geopolitical and military affairs, particularly in Northern Europe, from the Middle Ages to the modern era. It was also important globally through the power northern Europeans projected worldwide during much of the Middle Ages and into the modern era. The North Sea was the centre of the Vikings' rise. The Hanseatic League, the Dutch Republic, and the British each sought to gain command of the North Sea and access t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war.

Blyth, Northumberland
Blyth () is a town and civil parish in southeast Northumberland, England. It lies on the coast, to the south of the River Blyth and is approximately northeast of Newcastle upon Tyne. It has a population of about 37,000, as of 2011. The port of Blyth dates from the 12th century, but the development of the modern town only began in the first quarter of the 18th century.

Harwich
Harwich is a town in Essex, England, and one of the Haven ports on the North Sea coast. It is in the Tendring district. Nearby places include Felixstowe to the north-east, Ipswich to the north-west, Colchester to the south-west and Clacton-on-Sea to the south. It is the northernmost coastal town in Essex. Its position on the estuaries of the Stour and Orwell rivers, with its usefulness to mariners as the only safe anchorage between the Thames and the Humber, led to a long period of civil and military maritime significance. The town became a naval base in 1657 and was heavily fortified, with Harwich Redoubt, Beacon Hill Battery, and Bath Side Battery. Harwich is the likely launch point of the ''Mayflower'', which carried English Puritans to North America, and is the presumed birthplace of ''Mayflower'' captain Christopher Jones. Harwich today is contiguous with Dovercourt and the two, along with Parkeston, are often referred to collectively as ''Harwich''. History The tow ...
