HMS J2
HMS ''J2'' (later HMAS ''J2'') was a J-class submarine operated by the Royal Navy and the Royal Australian Navy. Design and construction The J class was designed by the Royal Navy in response to reported German submarines with surface speeds over .Bastock, ''Australia's Ships of War'', p. 86 They had a displacement of 1,210 tons surfaced, and 1,820 tons submerged. Each submarine was in length overall, with a beam of , and a draught of . The propulsion system was built around three propeller shafts; the J-class were the only triple-screwed submarines ever built by the British. Propulsion came from three 12-cylinder diesel motors when on the surface, and electric motors when submerged. Top speed was on the surface (the fastest submarines in the world at the time of construction), and underwater. Range was at . Armament consisted of six 18-inch (450 mm) torpedo tubes (four forward, one on each beam), plus a 4-inch deck gun. Originally, the gun was mounted on a breastwork fi ...

British J-class Submarine
The J-class submarines were seven submarines developed by the Royal Navy prior to the First World War in response to claims that Germany was developing submarines that were fast enough to operate alongside surface fleets. Six were completed during mid-1916, while a seventh entered service at the end of 1917. Although larger and more powerful than previous British submarines, the J class could not keep up with surface vessels, and operated independently during the war. Between them, the submarines sank a U-boat, and heavily damaged two battleships, with the loss of to friendly shelling. Following the war, the six surviving submarines were gifted to the Royal Australian Navy (RAN). All six were paid off during the 1920s. Two were scuttled as breakwaters in Port Phillip Bay, and four were scuttled in the ship graveyard off Port Phillip heads. Design Shortly before the First World War, incorrect reports reached the British fleet that the Germans were planning a class of fas ...

Ship Graveyard
A ship graveyard, ship cemetery or breaking yard is a location where the hulls of scrapped ships are left to decay and disintegrate, or left in reserve. Such a practice is now less common due to waste regulations and so some dry docks where ships are broken (to recycle their metal and remove dangerous materials like asbestos) are also known as ship graveyards. By analogy, the phrase can also refer to an area with many shipwrecks which have not been removed by human agency, instead being left to disintegrate naturally. These can form in places where navigation is difficult or dangerous (such as the Seven Stones, off Cornwall, or Blackpool, on the Irish Sea); or where many ships have been deliberately scuttled together ( as with the German High Seas Fleet at Scapa Flow); or where many ships have been sunk in battle (such as Ironbottom Sound, in the Pacific). The majority of the ships in the world are constructed in the developed countries. Ships last about 25–30 year ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scuttled Vessels Of Australia
Scuttling is the act of deliberately sinking a ship by allowing water to flow into the hull, typically by its crew opening holes in its hull. Scuttling may be performed to dispose of an abandoned, old, or captured vessel; to prevent the vessel from becoming a navigation hazard; as an act of self-destruction to prevent the ship from being captured by an enemy force; as a blockship to restrict navigation through a channel or within a harbor; to provide an artificial reef for divers and marine life; or to alter the flow of rivers. Notable historical examples Skuldelev ships (around 1070) The Skuldelev ships, five Viking ships, were sunk to prevent attacks from the sea on the Danish city of Roskilde. The scuttling blocked a major waterway, redirecting ships to a smaller one that required considerable local knowledge. Cog near Kampen (early 15th century) In 2012, a cog preserved from the keel up to the decks in the silt was discovered alongside two smaller vessels in the ...

World War I Submarines Of The United Kingdom
The world is the totality of entities, the whole of reality, or everything that exists. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique, while others talk of a "plurality of worlds". Some treat the world as one simple object, while others analyze the world as a complex made up of parts. In scientific cosmology, the world or universe is commonly defined as "the totality of all space and time; all that is, has been, and will be". Theories of modality talk of possible worlds as complete and consistent ways how things could have been. Phenomenology, starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon, or the "horizon of all horizons". In philosophy of mind, the world is contrasted with the mind as that which is represented by the mind. Theology conceptualizes the world in relation to God, for example, as God's creation, ...

Ships Built In Portsmouth
A ship is a large vessel that travels the world's oceans and other navigable waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. The earliest historical evidence of boats is found in Egypt during the 4th millennium BCE. In 2024, ships had a global cargo capacity of 2.4 billion tons, with the three largest classes being ships carrying dry bulk (43%), oil tankers (28%) and container ships (14%).

Port Phillip
Port Phillip (Kulin languages, Kulin: ''Narm-Narm'') or Port Phillip Bay is a horsehead-shaped bay#Types, enclosed bay on the central coast of southern Victoria (Australia), Victoria, Australia. The bay opens into the Bass Strait via a short, narrow channel (geography), channel known as The Rip, and is completely surrounded by suburbs and localities (Australia), localities of Victoria's two largest cities — metropolitan Greater Melbourne in the bay's main eastern portion north of the Mornington Peninsula, and the city of Greater Geelong in the much smaller western portion (known as the Corio Bay) north of the Bellarine Peninsula. Geographically, the bay covers and the shore stretches roughly , with the volume of water around . Most of the bay is navigable, although it is extremely shallow for its size — the deepest portion is only and half the bay is shallower than .

British Admiralty
The Admiralty was a Departments of the Government of the United Kingdom, department of the Government of the United Kingdom that was responsible for the command of the Royal Navy. Historically, its titular head was the Lord High Admiral of the United Kingdom, Lord High Admiral – one of the Great Officers of State. For much of its history, from the early Admiralty in the 18th century, 18th century until its abolition, the role of the Lord High Admiral was almost invariably put "in commission" and exercised by the Lords Commissioner of the Admiralty, who sat on the governing Board of Admiralty, rather than by a single person. The Admiralty was replaced by the Admiralty Board (United Kingdom), Admiralty Board in 1964, as part of the reforms that created the Ministry of Defence (United Kingdom), Ministry of Defence and its Navy Department (Ministry of Defence), Navy Department (later Navy Command (Ministry of Defence), Navy Command).

British 18-inch Torpedo
There have been a number of 18-inch (45cm) torpedoes in service with the Royal Navy of the United Kingdom. These have been used on ships of the Royal Navy and aircraft of both the Fleet Air Arm and Royal Air Force, while Royal Navy surface ships and submarines use 21-inch torpedoes. The British 18-inch torpedoes were in diameter, beginning with the "Fiume" Whitehead torpedo of 1890. Fiume Mark I Purchased from Whitehead with the first delivery in 1890, and a second delivery in 1891. The weapon utilized compressed air propulsion, and was prolific for its time, having been exported to multiple other navies across the world. The decision to adopt the 18-inch torpedo caliber was made by the Admiralty in 1889, with the Fiume Mark I being the first weapon of the type, soon thereafter followed by the RGF Mark I. In 1890, Whitehead established a torpedo factory in Weymouth, chiefly for the export market - but also in order to directly supply the Royal Navy with locally-manufactu ...

Orkney Islands
Orkney (), also known as the Orkney Islands, is an archipelago off the north coast of mainland Scotland. The plural name the Orkneys is also sometimes used, but locals now consider it outdated. Part of the Northern Isles along with Shetland, Orkney is 10 miles (16 km) north of Caithness and has about 70 islands, of which 20 are inhabited.Haswell-Smith (2004) pp. 336–403. The largest island, the Mainland, has an area of , making it the sixth-largest Scottish island and the tenth-largest island in the British Isles. Orkney's largest settlement, and also its administrative centre, is Kirkwall. Orkney is one of the 32 council areas of Scotland, as well as a constituency of the Scottish Parliament, a lieutenancy area, and an historic county. The local council is Orkney Islands Council. The islands have been inhabited for at least years, originally occupied by Mesolithic and Neolithic tribes and then by the Picts. Orkney was colonised and later annexed by the Kin ...
