HMS Dreadnought was one of the most revolutionary structures in shipbuilding of the twentieth century, and it was later named after battleships built in its likeness with "dreadnoughts". The revolutionary nature of HMS Dreadnought was mainly due to the fact that it was equipped with as many as 10 main artillery guns with a caliber of 305 mm, the fire control of which was carried out from one place. Moreover, the ship was powered by steam turbines, which made it the fastest battleship in the world at the time of launching. It also had carefully designed armor and watertight bulkheads, increasing its survivability on the battlefield. This revolutionary unit was the flagship of the Home Fleet in 1907-1912. The ship took a limited part in World War I - including: it did not participate in the Battle of Jutland in 1916. His only significant achievement was the sinking by ramming of the German U-29 submarine in 1915. HMS Dreadnought was scrapped in 1923.
HMS Humber was a British monitor from the First World War. The keel for this unit was laid in 1912, and the launch took place in June 1913. The total length of the ship at the time of launching was 81.31 meters and a width of 15 meters. Full displacement reached approx. 1250-1300 tons, and the maximum speed was approx. 12 knots. The armament at the time of the launch consisted of: two 152 mm guns, two 120 mm howitzers and four 76.2 mm guns. HMS Humber was initially built by the Vickers shipyard for Brazil under the name Javary, but at the outbreak of World War I it was bought by the Royal Navy, along with its sister ships Severn and Mersey. HMS Humber took an active part in World War I, from its first weeks. At the end of 1914, it operated off the coast of Belgium, and later was directed to the Mediterranean Sea and took part in an operation in the Gallipolli area in 1915. Then he was sent to Egypt, and from 1917 he was stationed in the port of Aqaba in what is now Jordan. In March 1919, HMS Humber returned to Great Britain to be sent to Russia later that year to assist the Whites in the Civil War. In 1920, it was sold.
