The Centurion Mk. I is a British tier 8 medium tank.

Development of the Centurion started in 1943. Designed as a "universal tank" to replace existing infantry and cruiser tanks, it entered service in 1947. A total of 100 vehicles of this series were manufactured from 1945 through 1946.

A notable step up from the Comet, featuring a great gun selection and still very agile, just like its predecessors, the Centurion Mk. I is a good tank for its tier. Although notably bulky and with spectacularly poor hull armor, it is quick on its feet and its 20-pounder gun features equally spectacular penetration and accuracy. It appears to have something of a weakness in that its ammunition rack and driver are both vulnerable to frontal hits. Fully upgraded though, it is a monster at long-range fighting and hill battles.

The Centurion Mk. I leads to the Centurion Mk. 7/1.

Historical Info

In 1943, the Directorate of Tank Design was asked to produce a new design for a heavy cruiser tank under the General Staff designation A41. After a series of fairly marginal designs in the A series in the past, and bearing in mind the threat posed by the German 88 mm gun, the War Office demanded a major revision of the design requirements, specifically: increased durability and reliability, and the ability to withstand a direct hit from the German 88 mm gun withn a maximum weight of 40 tons. The hull was to offer more protection against mines and top speed was not vital while agility was to be equal to that of Comet. A high reverse speed was also required.

Development history

The department responded by extending the long-travel five-wheel suspension used on the Comet with the addition of a sixth wheel and an extended spacing between the second and third wheels. The Christie suspension, with vertical spring coils between side armour plates, was replaced by a Horstmann suspension with external horizontal springs. The hull was redesigned with welded, sloped armour and featured a partially cast turret with the highly regarded 17 pounder as the main gun and a 20 mm Polsten cannon in an independent mounting to its left. With a Rover-built Rolls-Royce Meteor as used on the Comet and Cromwell, the new design would have excellent performance.

Shortly after the programme commenced, it became clear that the requirement to withstand 88 mm weapons would be impossible to meet within the permitted weight. The original specification had been set so that the A41 could be carried on the existing Mark I and Mark II transport trailers, which were limited to a 40-ton load. The War Ministry decided it would be wiser to build new trailers, rather than hamper what appeared to be a superb design. Even before prototypes of the original 40-ton design were completed, the design of a heavier version was well under way. The new version carried armour equal to the heaviest infantry tanks, and cross-country performance was superior to even the early cruiser tanks. The A41 was the first British tank that could "do it all", leading to the new designation "universal tank". The design mockup built by AEC Ltd was viewed in May 1944. Subsequently twenty pilot models were ordered with various armament combinations: ten with 17 pdr and 20mm Polsten gun of which half had a Besa machine gun in the turret rear and half an escape door, five with 17pdr and forward Besa and escape door, and five with QF 77mm gun and driver-operated hull machine gun. Prototypes of the original 40-ton design, the Centurion Mark I, had 76 mm of armour in the front glacis, which was thinner than the then current infantry tank designs such as the Churchill which had 101 mm, but the glacis plate was highly sloped and so the effective thickness of the armour was very high—a design feature shared by other effective designs such as the German Panther tank and Soviet T-34. The turret was extremely well armoured at 152 mm. The tank was also highly mobile, and easily outperformed the Comet in most tests. The uparmoured Centurion Mark II soon arrived; it had a new 118 mm-thick glacis and the side and rear armourhad been increased from 38 mm to 51 mm. Only a handful of Mk I Centurions had been produced when the Mk II replaced it on the production lines. Full production began in November 1945 with an order for 800 on production lines at Leyland Motors, Lancashire the Royal Ordnance Factories at Leeds and Woolwich, and Vickers at Elswick. The tank entered service in December 1946 with the 5th Royal Tank Regiment.

Soon after the Centurion's introduction, Royal Ordnance finished work on the Ordnance QF 20 pounder (84 mm) tank gun. By this point the usefulness of the 20 mm Polsten had been called into question, it being unnecessarily large for use against troops, so it was replaced with a Besa machine gun in a completely cast turret. The new Centurion Mark III also featured a fully automatic stabilisation system for the gun, allowing it to fire accurately while on the move, dramatically improving battlefield performance. Production of the Mk 3 began in 1948. The Mk 3 was so much more powerful than the Mk 1 and Mk 2 that the earlier designs were removed from service as soon as new Mk 3s arrived, and the older tanks were then either converted into the Centurion Armoured Recovery Vehicle (ARV) Mark 1 for use by the Royal Electrical and Mechanical Engineers or upgraded to Mk 3 standards. Improvements introduced with the Mk 3 included a more powerful version of the engine and a new gunsight and gun stabiliser. The 20 pounder gun was used only for a short time, until the Royal Ordnance Factories introduced the now legendary 105 mm L7 gun. All later variants of the Centurion, from Mark 5/2 on, used the L7. Design work for the Mk 7 was completed in 1953 with production beginning soon afterwards.

The Centurion was used as the basis for a range of specialist equipment, including combat engineering variants with a 165 mm demolition gun Armoured Vehicle Royal Engineers (AVRE). It is one of the longest-serving designs of all time, serving as a battle tank for the British and Australian armies from the Korean War (1950–1953) to the Vietnam War (1961–1972), and as an AVRE during the Gulf War in January–February 1991.
