Cerberus-class Monitor
The ''Cerberus''-class breastwork monitor was a pair of breastwork monitors built for the Royal Navy in the 1860s. Design Also referred to as " ironclads" and "turret ships", the ships of the ''Cerberus'' class were designed by Sir Edward Reed following requests by several dominions and colonies of the British Empire for warships to be used as coastal defence ships. The class consisted of two ships: , which was operated by the colony of Victoria, and , which spent her life operating in Bombay Harbour. The size of the ships was limited by cost. They were designed and built to be used as local defence ships, and it was not expected that they would ever need to be deployed far away from their bases. It was therefore possible to design them without sails or rigging and dependent only upon their engines, with a resulting limitation in their effective range. The absence of masts and rigging allowed more weight to be worked into the ship's armour. This also meant it was possible t ...

HMVS Cerberus
HMVS ''Cerberus'' (Her Majesty's Colony of Victoria, Victorian Ship) is a breastwork monitor that served in the Colonial navies of Australia#Victoria, Victoria Naval Forces, the Commonwealth Naval Forces (CNF), and the Royal Australian Navy (RAN) between 1871 and 1924. Built in Jarrow, UK, at Palmers Shipbuilding and Iron Company for the colony of Victoria (Australia), Victoria, Australia, under the supervision of Charles Pasley (engineer), Charles Pasley, ''Cerberus'' was completed in 1870, and arrived in Port Phillip, the port of Melbourne on the SE coast of Australia in 1871, where she spent the rest of her career. The monitor was absorbed into the CNF following Federation of Australia, Federation in 1901, and was renamed HMAS ''Cerberus'' when the navy became the RAN in 1911. By World War I, ''Cerberus'' weapons and boilers were inoperable; the ship served as a guardship and munitions store, while carrying the personnel of the fledgling Royal Australian Naval College on her ...

Coastal Defence Ship
Coastal 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. The Nordic countries and Thailand found them particularly appropriate for their island-dotted coastal waters. Some vessels had limited blue-water capabilities; others operated in rivers. The coastal defence ships differed from earlier monitors by having a higher freeboard and usually possessing both higher speed and a secondary armament; some examples also mounted casemated guns (monitors' guns were almost always in turrets). They varied in size from around 1,500 tons to 8,0 ...

Blackwall, London
Blackwall is an area of Poplar, London, Poplar, in the London Borough of Tower Hamlets, East London. The neighbourhood includes Leamouth and the Coldharbour, Tower Hamlets, Coldharbour conservation area. The area takes its name from a historic stretch of riverside wall built along an outside curve of the River Thames, Thames, to protect the area from flooding. Along with the rest of Poplar, Blackwall has its origin in the Stepney#Manor and Ancient Parish, Manor and Ancient Parish of Stepney. While mostly residential, the Poplar Dock and West India Docks, Blackwall Basin provide moorings for vessels. Setting and administration The area's significance derived from its position on an outside curve of the Thames, where currents slowed down, making it a sheltered spot useful to a range of shipping activities. This sheltered position was enhanced by the presence of the Blackwall Rock reef, though this could also be a danger to shipping. A further advantage of the area was that it lay ...

Breakwater (structure)
A breakwater is a permanent structure constructed at a coastal area to protect against tides, currents, waves, and storm surges. Breakwaters have been built since antiquity to protect anchorage (maritime), anchorages, helping isolate vessels from marine hazards such as wind-driven waves. A breakwater, also known in some contexts as a jetty or a Mole_(architecture), mole, may be connected to land or freestanding, and may contain a walkway or road for vehicle access. Part of a coastal management system, breakwaters are installed parallel to the shore to minimize erosion. On beaches where longshore drift threatens the erosion of beach material, smaller structures on the beach may be installed, usually perpendicular to the water's edge. Their action on waves and current is intended to slow the longshore drift and discourage mobilisation of beach material. In this usage they are more usually referred to as groynes. Purposes Breakwaters reduce the intensity of wave action in ins ...

Scuttled
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 t ...

Field Of Fire (weaponry)
The field of fire or zone of fire (ZF) of a weapon, or group of weapons, is the area around it that can easily and effectively be reached by projectiles from a given position. Field of fire The term originally came from the ''field of fire'' in front of forts (and similar defensive positions), cleared so there was no shelter for an approaching enemy. Sector of fire A similar term sector of fire is used to describe the area into which each gunner or group are ''allowed'' to fire. The boundaries are assigned by the commanding officer and thus can be arbitrary, even three-dimensional (a rifleman attacking a building might be assigned a set of windows to target). Arc of fire The arc of fire of a mounted gun is a horizontal (" traverse") angle range within which the gun (or guns) can be fired. It can be limited by the construction of the gun mount or obstacles (for example, superstructure of a ship). If there are no restrictions, the term ''all-round arc of fire'' is sometimes used. ...

Gun Turret
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Description Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the barbette. In the 1890s, armoured hoods (also known as "gun houses") were added to barbettes; these rotated with the platform (hence the term "hooded barbette"). By the early 20th century, these hoods were known as turrets. Modern warships have gun-m ...

Bombay Harbour
Mumbai Harbour (also English; Bombay Harbour or Front Bay, Marathi ''Mumba'ī bandar''), is a natural deep-water harbour in the southern portion of the Ulhas River estuary. The narrower, northern part of the estuary is called Thana Creek. The harbour opens to the Arabian Sea to the south. The historical island of Elephanta is one of the six islands that lie in the harbour. ''Front Bay'' is the official name of the harbour, so named because the city started as a tiny settlement facing the harbour. The waterbody behind the original settlement, forming an arc between the former Colaba island and Bombay island, up to the Malabar Hill promontory or peninsula, was similarly called Back Bay. Front Bay is home to the Mumbai Port, which lies in the south section of the western edge of the harbour. Jawaharlal Nehru Port and Navi Mumbai lie to the east on the Konkan mainland, and the city of Mumbai lies to the west on Salsette Island. The Gateway of India with its jetty for Elephant ...

Colony Of Victoria
The Colony of Victoria was a historical administrative division in Australia that existed from 1851 until 1901, when it federated with other colonies to form the Commonwealth of Australia. Situated in the southeastern corner of the Australian continent, Victoria played a significant role in the country's colonial history and development. History Establishment The Colony of Victoria, established in 1851, was carved out of the southeastern part of the Colony of New South Wales. This separation was fuelled by a combination of economic, political, and social factors, with a burgeoning population and a desire for local governance playing crucial roles. The discovery of gold in the region accelerated its development, transforming Victoria into a vibrant hub of activity and prosperity. The Gold Rush era The discovery of gold in 1851 near Ballarat and Bendigo marked a pivotal moment in Victoria's history. The ensuing gold rush attracted tens of thousands of immigrants from arou ...
