HSwMS Stockholm (1856)
HSwMS ''Stockholm'' was a ship of the line that served in the Swedish Navy and was built by Karlskrona naval shipyards, Karlskrona Naval Shipyard. She was named after Stockholm. Commissioned in 1857 and decommissioned in 1921. Design and description ''Stockholm'' was 56.6 meters long, 14.8 meters wide and had a draft of 6.9 meters. The vessel's displacement amounted to just over 2,846 tonnes. The machinery in Stockholm consisted of two steam boilers that generated steam for a Motala angle steam engine. The full engine power was about 800 indicated horsepower, which gave a maximum speed of 6.5 knots. When sailing, the propeller could be hoisted up into a shaft. At the time of launch, the equipment consisted of sixty-four 30-pound cannons, six 72-pound bomb cannons and a six-pound landing cannon. Furthermore, the ship was equipped with an 18-pound and a 12-pound cartridge. Construction and career ''Stockholm'' was laid down by Karlskrona naval shipyards, Karlskrona Naval S ...

Naval Ensign Of Sweden (1844-1905)
A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is projection of force into areas beyond a country's shores (for example, to protect sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broadly divided between riverine and littoral applications ( brown-water navy), open-ocean applications ...

Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ships Built In Karlskrona
A ship is a large watercraft that travels the world's oceans and other sufficiently deep Sea lane, 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, Naval warfare, warfare, Human migration, migration, colonization, and science. After the 15th century, Columbian Exchange, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. 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 Full-rigged ship, ship-rigged sailing ship with three or more masts, each of which is Square rig, square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacob Hägg
Jacob Hägg (22 July 1839 – 15 April 1931) was a Swedish naval officer and marine art, marine artist. He entered the Royal Swedish Naval Academy, Naval Academy in 1858, and was commissioned as an officer in 1863. He sailed on several long journeys, including one Vanadis expedition, circumnavigation of Earth. He entered the Fleet Staff in 1888, was appointed head of the Naval Academy in 1895 and promoted to Rear admiral (Sweden), rear admiral in 1899. In parallel to his military career, Hägg was also active as an artist. He made drawings and other graphic works, watercolours and oil paintings almost exclusively on marine subjects. He was also an active promoter of marine history and lobbied for the establishment of the Maritime Museum (Stockholm), Maritime Museum in Stockholm. His brother was the architect and artist Axel Haig. Background, childhood and family life Jacob Hägg was born at Katthamra, a small manor house in Östergarn on the Swedish island Gotland. His father an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
