Russian Submarine AG-12
The Russian submarine ''AG-12'' 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. She was scuttled by the Russians at Hanko in April 1918. Attempts were made by the Finns to salvage the vessel: She was raised in 1918 and transferred to Turku for repair, but this proved too costly and she was scrapped. Description ''AG-12'' 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 3-bladed propellers, each of which was driven by a diesel engine as well as a electric motors. This arrangement gave ''AG- ...

Electric Boat Company
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of positiv ...

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 r ...

Ships Built In Russia
A ship is a large watercraft that travels the world's oceans and other sufficiently deep 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. After the 15th century, 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 ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and 13% were con ...

Vulcan (Turku Shipyard)
Aktiebolaget Vulcan was an engineering works and shipbuilding company that operated in Turku, Finland between 1898 and 1924. The company was founded by local businessmen, who bought the production facilities from previously ceased Åbo Mekaniska Verkstads Ab. The company produced ships, engines, pumps and other engineering products. Vulcan had a facility also in Saint Petersburg, where it produced military supplies for the Imperial Russian Army. The company struggled due to losses caused by the Russian Revolution and declined orders.

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 Br ...

Trans-Siberian Railroad
The Trans-Siberian Railway (TSR; , , ) 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 (namely Mongolia, China, and North Korea). Additionally, there have been proposals and talks to expand the network to Tokyo, Japan, with new bridges that would connect the mainland railway through the Russian island of Sakhalin and the Japanese island of Hokkaido.
