BL 13.5-inch Mk V Naval Gun
The BL 13.5 inch Mk V gunMk V = Mark 5. Britain used Roman numerals to identify Marks (models) of ordnance until after World War II. This was the fifth model of British 13.5 inch gun was a British heavy naval gun, introduced in 1912 as the main armament for the new super-dreadnought battleships of the . The calibre was 13.5 inches (343 mm) and the barrels were 45 calibres long i.e. 607.5 inches (15.43 m). The guns were greatly superior and unrelated to the earlier 13.5-inch (30-calibre) Mk I to Mk IV guns used on the , and es completed between 1888 and 1896. Background The gun was developed in response to the relative failure of the British high-velocity 12-inch Mk XI and XII guns. Unlike Germany, which developed and deployed successful high-velocity 12-inch guns, Britain in this case switched to guns firing larger and heavier shells at lower velocity which could achieve similar performance in range and armour penetration but could deliver a heavier ex ...

HMS Thunderer (1911)
HMS ''Thunderer'' was the fourth and last dreadnought battleship built for the Royal Navy in the early 1910s. She spent the bulk of her career assigned to the Home and Grand Fleets. Aside from participating in the Battle of Jutland in May 1916 and the inconclusive action of 19 August, her service during World War I generally consisted of routine patrols and training in the North Sea. After the Grand Fleet was dissolved in early 1919, ''Thunderer'' was transferred back to the Home Fleet for a few months before she was assigned to the Reserve Fleet. The ship was converted into a training ship for naval cadets in 1921 and served in that role until she was sold for scrap in late 1926. While being towed to the scrapyard, ''Thunderer'' ran aground; the ship was refloated and subsequently broken up. Design and description The ''Orion''-class ships were designed in response to the beginnings of the Anglo-German naval arms race and were much larger than their predecessors of the t ...

Dover
Dover () is a town and major ferry port in Kent, South East England. It faces France across the Strait of Dover, the narrowest part of the English Channel at from Cap Gris Nez in France. It lies south-east of Canterbury and east of Maidstone. The town is the administrative centre of the Dover District and home of the Port of Dover. Archaeological finds have revealed that the area has always been a focus for peoples entering and leaving Britain. The name derives from the River Dour that flows through it. In recent times the town has undergone transformations with a high-speed rail link to London, new retail in town with St James' area opened in 2018, and a revamped promenade and beachfront. This followed in 2019, with a new 500m Pier to the west of the Harbour, and new Marina unveiled as part of a £330m investment in the area. It has also been a point of destination for many illegal migrant crossings during the English channel migrant crisis. The Port of Dover pro ...

BL 15 Inch Mk I Naval Gun
The BL 15-inch Mark I succeeded the BL 13.5-inch Mk V naval gun. It was the first British 15-inch (381 mm) gun design and the most widely used and longest lasting of any British designs, and arguably the most successful heavy gun ever developed by the Royal Navy. It was deployed on capital ships from 1915 until 1959 and was a key Royal Navy gun in both World Wars. Design Gun This gun was an enlarged version of the successful BL 13.5-inch Mk V naval gun. It was specifically intended to arm the new s as part of the British response to the new generation of Dreadnought battleships Germany was building, during the naval arms race leading up to World War I. Due to the urgency of the times, the normally slow and cautious prototype and testing stages of a new gun's development were bypassed, and it was ordered straight from the drawing board. Despite its hurried development process, the gun met all expectations and was a competitive battleship main armament throughout both World ...

Grand Slam (bomb)
The Bomb, Medium Capacity, (Grand Slam) was a earthquake bomb used by RAF Bomber Command against German targets towards the end of the Second World War. The bomb was originally called Tallboy Large until the term Tallboy got into the press and the code name was replaced by "Grand Slam". The bomb was similar to a large version of the Tallboy bomb but a new design and closer to the size that its inventor, Barnes Wallis, had envisaged when he developed the idea of an earthquake bomb. Medium Capacity (M.C.) bombs were designed to remedy the shortcomings of General Purpose (G.P.) bombs, with a greater blast and casings which were robust enough to confer a considerable capacity to penetrate, especially the Tallboy and Grand Slam. The Grand Slam case was made of a chrome-molybdenum alloy steel and had a charge-to-weight ratio of over 43 per cent. Conventional Avro Lancaster bombers could not carry the bomb and 32 Lancaster B.Mk 1 (Special)s with more powerful engines, a stronger ...

Isle Of Grain
Isle of Grain (Old English ''Greon'', meaning gravel) is a village and the easternmost point of the Hoo Peninsula within the district of Medway in Kent, south-east England. No longer an island and now forming part of the peninsula, the area is almost all marshland and is a major habitat for diverse wetland birds. The village constitutes a civil parish, which at the 2011 census had a population of 1,648, a net decrease of 83 people in 10 years.

Cross-Channel Guns In The Second World War
The Dover Strait coastal guns were long-range coastal artillery batteries that were sited on both sides of the English Channel during the Second World War. The British built several gun positions along the coast of Kent, England while the Germans fortified the Pas-de-Calais in occupied France. The Strait of Dover was strategically important because it is the narrowest part of the English channel. Batteries on both sides attacked shipping as well as bombarding the coastal towns and military installations. The German fortifications would be incorporated into the Atlantic Wall which was built between 1942 and 1944. German installations After the Fall of France in June 1940, Adolf Hitler personally discussed the possibility of invasion with ''Großadmiral'' (Grand Admiral) Erich Raeder, the Commander-in-Chief of the ''Kriegsmarine'' (German Navy) on 21 May 1940. Almost a month later on 25 June he ordered '' Oberkommando der Wehrmacht'' (''OKW'', supreme command of the armed forces) t ...

St Margaret's At Cliffe
St. Margaret's at Cliffe is a three-part village situated just off the coast road between Deal and Dover in Kent, England. The centre of the village is about ¾ mile (1km) from the sea, with the residential area of Nelson Park further inland, and St Margaret's Bay situated along and below the cliffs north of South Foreland.

Stratosphere
The stratosphere () is the second layer of the atmosphere of the Earth, located above the troposphere and below the mesosphere. The stratosphere is an atmospheric layer composed of stratified temperature layers, with the warm layers of air high in the sky and the cool layers of air in the low sky, close to the planetary surface of the Earth. The increase of temperature with altitude is a result of the absorption of the Sun's ultraviolet (UV) radiation by the ozone layer. The temperature inversion is in contrast to the troposphere, near the Earth's surface, where temperature decreases with altitude. Between the troposphere and stratosphere is the tropopause border that demarcates the beginning of the temperature inversion. Near the equator, the lower edge of the stratosphere is as high as , at midlatitudes around , and at the poles about . Temperatures range from an average of near the tropopause to an average of near the mesosphere. Stratospheric temperatures also vary ...

Large-calibre Artillery
The formal definition of large-calibre artillery used by the United Nations Register of Conventional Arms (UNROCA) is " guns, howitzers, artillery pieces, combining the characteristics of a gun, howitzer, mortar, or multiple-launch rocket system, capable of engaging surface targets by delivering primarily indirect fire, with a calibre of 75 millimetres and above". This definition, shared by the Arms Trade Treaty and the Treaty on Conventional Armed Forces in Europe, is derived from a definition in United Nations General Assembly Resolution 46/36L, which set a threshold of 100mm. Several grammatical changes were made to that latter in 1992 and the threshold was lowered in 2003 to yield the current definition, as endorsed by UN General Assembly Resolution 58/54. Historically, large-calibre weapons have included bombards and siege guns. Late Middle Ages In the context of late medieval siege warfare the term superguns applies to stone-firing bombards with a ball diameter of ...
