R38
The ''R.38'' class (also known as the ''A'' class) of rigid airships was designed for Britain's Royal Navy during the final months of the First World War, intended for long-range patrol duties over the North Sea. Four similar airships were originally ordered by the Admiralty, but orders for three of these (''R.39'', ''R.40'' and ''R.41'') were cancelled after the armistice with Germany and ''R.38'', the lead ship of the class, was sold to the United States Navy in October 1919 before completion. On 24 August 1921, ''R.38'' (designated ZR-2 by the USN) was destroyed by a structural failure while in flight over the city of Hull. It crashed into the Humber Estuary, killing 44 out of the 49 crew aboard. At the time of its first flight it was the world's largest airship. Its destruction was the first of the great airship disasters, followed by the Italian-built US semi-rigid airship ''Roma'' in 1922 (34 dead), the French '' Dixmude'' in 1923 (52 dead), the USS ''Shenandoah'' in 1 ...

Sunbeam Cossack
The Sunbeam Cossack was a British 12-cylinder aero engine that was first run in 1916. The Cossack spawned a family of engines from Sunbeam. Design and development As the First World War raged through 1914 and 1915, The Admiralty demanded engines with more power for its existing and future aircraft. The problem was exemplified by the Short Type 184 seaplanes of the RNAS, powered by Sunbeam Mohawk engines, which could barely lift the standard air-dropped torpedo with crew reduced to two and minimal fuel. An engine with a base rating of at least was demanded by the Admiralty. Responses came from Rolls-Royce with the Rolls-Royce Eagle and Sunbeam with the Sunbeam Cossack. Louis Coatalen designed the Cossack as a twin overhead camshaft 60° V-12, with four valves per cylinder, bore of and stroke of . Output from the Cossack was at 2,000rpm, with a running weight of , driving a large diameter propeller through a 2:1 reduction gear. Construction of the Cossack was largely of al ...

R101
R101 was one of a pair of British rigid airships completed in 1929 as part of a British government programme to develop civil airships capable of service on long-distance routes within the British Empire. It was designed and built by an Air Ministry–appointed team and was effectively in competition with the government-funded but privately designed and built R100. When built, it was the world's largest flying craft at in length, and it was not surpassed by another hydrogen-filled rigid airship until the LZ 129 ''Hindenburg'' was launched seven years later. After trial flights and subsequent modifications to increase lifting capacity, which included lengthening the ship by to add another gasbag,"R101".

Zeppelins
A Zeppelin is a type of rigid airship named after the German inventor Count Ferdinand von Zeppelin () who pioneered rigid airship development at the beginning of the 20th century. Zeppelin's notions were first formulated in 1874Eckener 1938, pp. 155–157. and developed in detail in 1893.Dooley 2004, p. A.187. They were patented in Germany in 1895 and in the United States in 1899. After the outstanding success of the Zeppelin design, the word ''zeppelin'' came to be commonly used to refer to all rigid airships. Zeppelins were first flown commercially in 1910 by Deutsche Luftschiffahrts-AG (DELAG), the world's first airline in revenue service. By mid-1914, DELAG had carried over 10,000 fare-paying passengers on over 1,500 flights. During World War I, the German military made extensive use of Zeppelins German strategic bombing during World War I, as bombers and aerial reconnaissance in World War I, as scouts, resulting in over 500 deaths in bombing raids in Britain. The defeat of ...

Humber
The Humber is a large tidal estuary on the east coast of Northern England. It is formed at Trent Falls, Faxfleet, by the confluence of the tidal rivers Ouse and Trent. From there to the North Sea, it forms part of the boundary between the East Riding of Yorkshire on the north bank and North Lincolnshire on the south bank. Although the Humber is an estuary from the point at which it is formed, many maps show it as the River Humber. Below Trent Falls, the Humber passes the junction with the Market Weighton Canal on the north shore, the confluence of the River Ancholme on the south shore; between North Ferriby and South Ferriby and under the Humber Bridge; between Barton-upon-Humber on the south bank and Kingston upon Hull on the north bank (where the River Hull joins), then meets the North Sea between Cleethorpes on the Lincolnshire side and the long and thin headland of Spurn Head to the north. Ports on the Humber include the Port of Hull, the Port of Grimsby and the P ...

Rigid Airship
A rigid airship is a type of airship (or dirigible) in which the envelope is supported by an internal framework rather than by being kept in shape by the pressure of the lifting gas within the envelope, as in blimps (also called pressure airships) and semi-rigid airships. Rigid airships are often commonly called Zeppelins, though this technically refers only to airships built by the Luftschiffbau Zeppelin company. In 1900, Count Ferdinand von Zeppelin successfully performed the maiden flight of his first airship; further models quickly followed. Prior to the First World War, Germany was a world leader in the field, largely attributable to the work of von Zeppelin and his Luftschiffbau Zeppelin company. During the conflict, rigid airships were tasked with various military duties, which included their participation in Germany's strategic bombing campaign. Numerous rigid airships were produced and employed with relative commercial success between the 1900s and the late 1930s. The ...

Airship
An airship or dirigible balloon is a type of aerostat or lighter-than-air aircraft that can navigate through the air under its own power. Aerostats gain their lift from a lifting gas that is less dense than the surrounding air. In early dirigibles, the lifting gas used was hydrogen, due to its high lifting capacity and ready availability. Helium gas has almost the same lifting capacity and is not flammable, unlike hydrogen, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only available for airships in that country. Most airships built since the 1960s have used helium, though some have used hot air.A few airships after World War II used hydrogen. The first British airship to use helium was the ''Chitty Bang Bang'' of 1967. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells. An airship also has engines, crew, and optionally also payload accommodation ...

Dixmude (airship)
The ''Dixmude'' was a Zeppelin airship built for the Imperial German Navy as L 72 (c/n ''LZ 114'') and unfinished at the end of the First World War, when it was given to France as war reparations and recommissioned in French Navy service and renamed ''Dixmude''. It was lost when it exploded in mid-air on 21 December 1923 off the coast of Sicily, killing all 52 (42 crew and ten passengers) on board. This was one of the first of the great airship disasters, preceded by the crash of the British ''R38'' in 1921 (44 dead) and the US airship ''Roma'' in 1922 (34 dead), and followed by the destruction of the USS ''Shenandoah'' in 1925 (14 dead) the British ''R101'' in 1930 (48 dead), the USS ''Akron'' in 1933 (73 dead) and the German ''Hindenburg'' in 1937 (36 dead). Name The ship was named after the Belgian city of Diksmuide (French: ''Dixmude''), and specifically, in honour of the Fusiliers Marins at the battle of Diksmuide. It was the first of three ships named ''Dixmude''. H ...

Short Brothers
Short Brothers plc, usually referred to as Shorts or Short, is an aerospace company based in Belfast, Northern Ireland. Shorts was founded in 1908 in London, and was the first company in the world to make production aeroplanes. It was particularly notable for its flying boat designs manufactured into the 1950s. In 1943, Shorts was nationalised and later denationalised, and in 1948 moved from its main base at Rochester, Kent to Belfast. In the 1960s, Shorts mainly produced turboprop airliners, major components for aerospace primary manufacturers, and missiles for the British Armed Forces. Shorts was primarily government-owned until being bought by Bombardier in 1989, and is today the largest manufacturing concern in Northern Ireland. In November 2020, Bombardier sold its Belfast operations to Spirit AeroSystems. The company's products include aircraft components, engine nacelles and aircraft flight control systems for its parent company Bombardier Aerospace, and for Boeing ...

USS Los Angeles (ZR-3)
USS ''Los Angeles'' was a rigid airship, designated ZR-3, which was built in 1923–1924 by the Zeppelin company in Friedrichshafen, Germany, as war reparations. It was delivered to the United States Navy in October 1924 and after being used mainly for experimental work, particularly in the development of the American parasite fighter program, was decommissioned in 1932. Design The second of four vessels to carry the name USS ''Los Angeles'', the airship was built for the United States Navy as a replacement for the Zeppelins that had been assigned to the United States as war reparations following World War I, and had been sabotaged by their crews in 1919. Under the terms of the Treaty of Versailles Luftschiffbau Zeppelin were not permitted to build military airships. In consequence ''Los Angeles'', which had the Zeppelin works number LZ 126, was built as a passenger airship, although the treaty limitation on the permissible volume was waived, it being agreed that a craft ...

War Reparations
War reparations are compensation payments made after a war by one side to the other. They are intended to cover damage or injury inflicted during a war. History Making one party pay a war indemnity is a common practice with a long history. Rome imposed large indemnities on Carthage after the First (Treaty of Lutatius) and Second Punic Wars. Some war reparations induced changes in monetary policy. For example, the French payment following the Franco-Prussian war played a major role in Germany's decision to adopt the gold standard; the 230 million silver taels in reparations imposed on defeated China after the First Sino-Japanese War led Japan to a similar decision. There have been attempts to codify reparations both in the Statutes of the International Criminal Court and the UN Basic Principles on the Right to a Remedy and Reparation for Victims, and some scholars have argued that individuals should have a right to seek compensation for wrongs they sustained during warfare ...

Scuttling Of The German Fleet At Scapa Flow
Shortly after the end of the First World War, the German Kaiserliche Marine was scuttled by its sailors while held off the harbor of the British Royal Navy base at Scapa Flow, in the Orkney Islands of Scotland. The High Seas Fleet was interned there under the terms of the Armistice while negotiations took place over the fate of the ships. Fearing that either the UK would seize the ships unilaterally or the German government at the time might reject the Treaty of Versailles and resume the war effort (in which case the ships could be used against Germany), Admiral Ludwig von Reuter decided to scuttle the fleet. The scuttling was carried out on 21 June 1919. Intervening British guard ships were able to beach some of the ships, but 52 of the 74 interned vessels sank. Many of the wrecks were salvaged over the next two decades and were towed away for scrapping. Those that remain are popular diving sites. The ships are a source of low-background steel. Background The signing ...
