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.
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. [3] [ 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. [4] [5]
The vehicle obtained seems, on close examination of photographs[ 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.[ 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)[ citation needed ], extensively redesigned, enlarged and with several faults that Christie had not addressed rectified. [1] [6] A new company Nuffield Mechanization & Aero Limited was formed for the development and production of the design. [7]
At a meeting of the General Staff, an official specification was determined, which included 30 mm (1.2 in) armour, a 2-pounder gun and a road speed of 30 miles per hour (48 km/h). A subsequent review of the specification by Martel and Percy Hobart approved 30 mm armour all round provided cross-country speed could be kept at 25 miles per hour (40 km/h). Pending the delivery of the A13, an interim design was approved from the A7, A9 and A10, the A9 being selected. [3] [ page needed ] Orders for the resulting Mk. I's were limited pending the arrival of the A13. [7]
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. [8] The Mk III weighed 14 long tons (14 t), had a crew of four, a 340 horsepower (250 kW) engine and a top speed of 30 miles per hour (48 km/h) 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. [9]
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. [2] The design was used as the basis for the Cruiser Mk IV. [7]
The Tank, Infantry, Mk III, Valentine was an infantry tank produced in the United Kingdom during World War II. More than 8,000 of the type were produced in eleven marks, plus various specialised variants, accounting for approximately a quarter of wartime British tank production. The many variants included riveted and welded construction, petrol and diesel engines and a progressive increase in armament. It was supplied in large numbers to the USSR and built under licence in Canada. It was used extensively by the British in the North African campaign. Developed by Vickers, it proved to be both strong and reliable.
The Cromwell tank, officially Tank, Cruiser, Mk VIII, Cromwell (A27M), was one of the series of cruiser tanks fielded by Britain in the Second World War. Named after the English Civil War-era military leader Oliver Cromwell, the Cromwell was the first tank put into service by the British to combine high speed from a powerful, reliable engine and reasonable armour. The intended dual-purpose high velocity gun could not be fitted in the turret, so a medium velocity dual purpose gun was fitted instead. Further development of the Cromwell combined with a high velocity gun led to the Comet tank.
Crusader, in full "Tank, Cruiser Mk VI, Crusader", also known by its General Staff number A.15, was one of the primary British cruiser tanks during the early part of the Second World War. Over 5,000 tanks were manufactured and they made important contributions to the British victories during the North African campaign. The Crusader tank would not see active service beyond Africa but the chassis of the tank was modified to create anti-aircraft, fire support, observation, communication, bulldozer and recovery vehicle variants.
The Tank, Cruiser, Mk I (A9) was a British cruiser tank of the interwar period. It was the first cruiser tank: a fast tank designed to bypass the main enemy lines and engage the enemy's lines of communication, as well as enemy tanks. The Cruiser Mk II was a more heavily armoured adaptation of the Mark I, developed at much the same time.
The Tank, Cruiser, Mk II (A10), was a cruiser tank developed alongside the A9 cruiser tank, and was intended to be a heavier, infantry tank version of that type. In practice, it was not deemed suitable for the infantry tank role and was classified as a "heavy cruiser". It served briefly in World War II.
The Comet tank or Tank, Cruiser, Comet I (A34) was a British cruiser tank that first saw use near the end of the Second World War, during the Western Allied invasion of Germany. The Comet was developed from the earlier Cromwell tank and mounted the new 17 pdr High Velocity (HV) gun, in a lower profile, partly-cast turret. This gun was effective against late-war German tanks, including the Panther at medium range, and the Tiger.
The cruiser tank was a British tank concept of the interwar period for tanks designed as modernised armoured and mechanised cavalry, as distinguished from infantry tanks. Cruiser tanks were developed after medium tank designs of the 1930s failed to satisfy the Royal Armoured Corps. The cruiser tank concept was conceived by Giffard Le Quesne Martel, who preferred many small light tanks to swarm an opponent, instead of a few expensive and unsatisfactory medium tanks. "Light" cruiser tanks carried less armour and were correspondingly faster, whilst "heavy" cruiser tanks had more armour and were slightly slower.
The Cruiser tank Mk V or A13 Mk III Covenanter was a British cruiser tank of the Second World War. The Covenanter was the first cruiser tank design to be given a name. Designed by the London, Midland and Scottish Railway as a better-armoured replacement for the Cruiser Mark IV, it was ordered into production in 1939 before pilot models were built. Problems with the design became apparent only after production was under way.
The Cruiser Tank Mk IV was a British cruiser tank of the Second World War. It followed directly on from the Tank, Cruiser, Mk III. The first Mk IVs were Mk IIIs with extra armour fitted to the turret. Later Mk IVAs were built with the complete extra armour. The tank was used in France in 1940 and in the early part of the war in North Africa, before being withdrawn from service. A fast vehicle compared to other British tanks of the early part of the war, it was probably the best tank Britain had in 1940. In total, 955 of these tanks were built.
The Tank, Light, Mk VI was a British light tank, produced by Vickers-Armstrongs in the late 1930s, which saw service during the Second World War.
The Liberty L-12 is an American water-cooled 45° V-12 aircraft engine displacing 1,649 cubic inches (27 L) and making 400 hp (300 kW) designed for a high power-to-weight ratio and ease of mass production. It saw wide use in aero applications, and, once marinized, in marine use both in racing and runabout boats.
The Tank, Cruiser, Mk VII Cavalier (A24) was an interim design of British cruiser tank during the Second World War.
Horstmann suspension, also known as Horstman, Vickers-Horstman and rarely Slow Motion, is a type of tracked suspension devised by British tank designer John Carden and worked into a production design by engineer Sidney Horstmann.
This article lists British armoured fighting vehicle production during the Second World War. The United Kingdom produced 27,528 tanks and self-propelled guns from July 1939 to May 1945, as well as 26,191 armoured cars and 69,071 armoured personnel carriers.
The A-13 was a specification of British Cruiser tanks produced by the General Staff Directorate of Tank Design before and during the Second World War.
John Walter Christie was an American engineer and inventor. He is known best for developing the Christie suspension system used for several World War II-era tank designs, most notably the Soviet BT and T-34 tanks series, and the United Kingdom Covenanter and Crusader Cruiser tanks, as well as the Comet heavy cruiser tank.
The British Army made extensive use of a variety of combat vehicles during the Second World War. This article is a summary of those vehicles.
