Russian Submarine AG 16
The ''AG-16'' was an AG-class submarine, designed by the American Holland Torpedo Boat Company/ Electric Boat Company, built for the Imperial Russian Navy during World War I. The submarine was fabricated in Canada, shipped to Russia and reassembled for service with the Baltic Fleet. The boat was originally named ''AG-13'', but was redesignated ''AG-16'' after '' AG-15'' sank and later repaired in 1917. She was scuttled by the Russians at Hanko in April 1918. Attempts were made by the Finns to salvage the vessel: the boat was raised in 1918 and transferred to Helsinki for repair, but this proved too costly and she was scrapped in 1929. Description ''AG-13'' was a single-hulled submarine, with a pressure hull divided into five watertight compartments. The submarine had a length of overall, a beam of and a draft of . She displaced on the surface and submerged. The AG-class submarines had a diving depth of and a crew of 30 officers and enlisted men. The submarine had two ...

Electric Boat Company
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of either a positive or negative electric charge produces an electric field. The motion of electric charges is an electric current and produces a magnetic field. In most applications, Coulomb's law determines the force acting on an electric charge. Electric potential is the work done to move an electric charge from one point to another within an electric field, typically measured in volts. Electricity plays a central role in many modern technologies, serving in electric power where electric current is used to energise equipment, and in electronics dealing with electrical c ...

British Submarine Flotilla In The Baltic
A British submarine flotilla operated in the Baltic Sea for three years during the First World War. The squadron of nine submarines was attached to the Russian Baltic Fleet. The main task of the flotilla was to prevent the import of iron ore from Sweden to Imperial Germany. The success of the flotilla also forced the German Navy in the Baltic to keep to their bases and denied the German High Seas Fleet a training ground. The flotilla was based in Reval (Tallinn), and for most of its career commanded by Captain Francis Cromie. The flotilla originally consisted of six E-class and five C-class submarines. The smaller C-class submarines reached the Baltic Sea from the White Sea via northern rivers; the long-range E-class submarines managed to enter the German backwaters by passing undetected through the narrow and shallow Danish straits. Two submarines were lost to stranding and one went missing, now presumed sunk by a mine. In 1918, the German occupation of Tallinn and the B ...

Trans-Siberian Railroad
The Trans-Siberian Railway, historically known as the Great Siberian Route and often shortened to Transsib, is a large railway system that connects European Russia to the Russian Far East. Spanning a length of over , it is the longest railway line in the world. It runs from the city of Moscow in the west to the city of Vladivostok in the east. During the period of the Russian Empire, government ministers—personally appointed by Alexander III and his son Nicholas II—supervised the building of the railway network between 1891 and 1916. Even before its completion, the line attracted travelers who documented their experiences. Since 1916, the Trans-Siberian Railway has directly connected Moscow with Vladivostok. , expansion projects remain underway, with connections being built to Russia's neighbors Mongolia, China, and North Korea. Additionally, there have been proposals and talks to expand the network to Tokyo, Japan, with new bridges or tunnels that would connect the mainl ...

Knock-down Kit
A knock-down kit (also knockdown kit, knocked-down kit, or simply knockdown or KD) is a collection of parts required to assemble a product. The parts are typically manufactured in one country or region, and then exported to another country or region for final assembly. CBU, on the other hand, stands for "Completely Built Up" and signifies import of a finished product. Definitions A common form of knock-down is a complete knock-down (CKD), which is a kit of entirely unassembled parts of a product. It is also a method of supplying parts to a market, particularly in shipping to foreign nations, and serves as a way of counting or pricing. CKD is a common practice in the automotive industry, automotive, bus, heavy truck, and rail transport, rail vehicle industries, as well as electronics, furniture and other products. Businesses sell knocked-down kits to their foreign affiliates or licensees for various reasons, including the avoidance of import taxes, to receive tax preferences for ...

Deck Gun
A deck gun is a type of naval artillery mounted on the deck of a submarine. Most submarine deck guns were open, with or without a shield; however, a few larger submarines placed these guns in a turret. The main deck gun was a dual-purpose weapon used to sink merchant shipping or shell shore targets, or defend the submarine on the surface from enemy aircraft and warships. Typically a crew of three operated the gun, while others were tasked with supplying ammunition. A small locker box held a few 'ready-use' rounds. With a well-drilled, experienced crew, the rate of fire of a deck gun could be 15 to 18 aimed shots per minute. Some submarines also had additional deck guns like auto-cannons and machine guns for anti-aircraft defense. While similar unenclosed guns are often found on surface warships as secondary or defensive armament (such as the US Navy's 5-inch (127 mm)/25 caliber gun which was removed from battleships to mount on submarines), the term "deck gun" normally re ...

Fuel Oil
Fuel oil is any of various fractions obtained from the distillation of petroleum (crude oil). Such oils include distillates (the lighter fractions) and residues (the heavier fractions). Fuel oils include heavy fuel oil (bunker fuel), marine fuel oil (MFO), furnace oil (FO), gas oil (gasoil), heating oils (such as home heating oil), diesel fuel, and others. The term ''fuel oil'' generally includes any liquid fuel that is burned in a furnace or boiler to generate heat ( heating oils), or used in an engine to generate power (as motor fuels). However, it does not usually include other liquid oils, such as those with a flash point of approximately , or oils burned in cotton- or wool-wick burners. In a stricter sense, ''fuel oil'' refers only to the heaviest commercial fuels that crude oil can yield, that is, those fuels heavier than gasoline (petrol) and naphtha. Fuel oil consists of long-chain hydrocarbons, particularly alkanes, cycloalkanes, and aromatics. Small molecul ...

Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p. 5. This is accomplished by means of its "draft marks". A merchant vessel has t ...
