The Tank, Cruiser, Mk III, also known by its General Staff specification number A13 Mark I, was a British cruiser tank of the Second World War. It was the first British cruiser tank to use the Christie suspension system, which gave higher speeds and better cross-country performance; previous cruiser tank models had used triple wheeled bogie suspension.
Design and development
British cruiser tank design began with the Mk I and somewhat heavier Mk II in the mid-1930s. Just as prototypes were arriving in 1936, General Giffard LeQuesne Martel, a pioneer in tank design who had published works on armoured warfare and pioneered the lightly armoured "tankette" to enhance infantry mobility, became Assistant Director of Mechanization at the War Office.[1]Шаблон:Page needed
Later that year, Martel witnessed demonstrations of Soviet tank designs, including the BT tank, which had been influenced by American J. Walter Christie's work. Martel urged the adoption of the Christie suspension and Christie's practice of using a lightweight aircraft engine, such as the Liberty Engine. The government authorized the purchase and licensing of a Christie design via the Nuffield Organization, rather than contact the Soviet authorities.[2][3]
The vehicle obtained seems, on close examination of photographsШаблон:Citation needed, not to be Christie's prototype M1931 but a production "T3 Medium", the US Army having decided to replace this model c1934. Why this survivor was sent to Britain is unknown, though it is possible it was the only available example, hastily put into operable condition but minus its turret. On arrival it was given British War Department number T2086, the road registration BMX841 and the Mechanical Experimentation Establishment's experimental number 958.Шаблон:Citation needed After trials it was sent to Morris Commercial Cars Ltd, Birmingham and disassembled for study, Lord Nuffield (head of the Morris companies) had already agreed to buy the patent rights that would allow his company to develop the design that would become the basis of the Cruiser Mk III (A13)Шаблон:Citation needed, extensively redesigned, enlarged and with several faults that Christie had not addressed rectified.[4][5] A new company Nuffield Mechanization & Aero Limited was formed for the development and production of the design.[6]
At a meeting of the General Staff, an official specification was determined, which included Шаблон:Convert armour, a 2-pounder gun and a road speed of Шаблон:Convert. A subsequent review of the specification by Martel and Percy Hobart approved Шаблон:Nowrap all round provided cross-country speed could be kept at Шаблон:Convert. Pending the delivery of the A13, an interim design was approved from the A7, A9 and A10, the A9 being selected.[1]Шаблон:Page needed Orders for the resulting Mk. I's were limited pending the arrival of the A13.[6]
The first prototype (A13E1) was delivered in 1937. Following the testing of two prototypes, the A13 was ordered into production. The original order was for 50 tanks; 43 had been delivered by the start of the war and 22 more in September–December 1939.[7] The Mk III weighed Шаблон:Convert, had a crew of four, a Шаблон:Convert engine and a top speed of Шаблон:Convert and was armed with a 2 pounder gun and a machine-gun. When it was introduced into service in 1937, the army still lacked a formal tank division.[8]
Combat history
Like most British cruisers, the A13 was fast but under-armoured and mechanically unreliable. As part of the British Expeditionary Force sent to France, the Cruiser Mark III equipped units in the 1st Armoured Division, but most were lost. A few were used in Greece and in the Western Desert 1940–1941 (Libya), where they equipped units of the 7th Armoured Division.[9] The design was used as the basis for the Cruiser Mk IV.[6]
