Usage in the battles

The Centurion Mk. 3 is an effective medium tank if played to its strengths. If one wants to keep it simple, just use the powerful gun to snipe from distance. More advanced tankers can utilize the not too impressive max speed (35kmph/22mph) to move with this medium tank into the flanks of enemy tanks (close to the border of a map) and search for positions like hills and ridges where one can make use of the amazing -10° gun depression to hide the vulnerable lower plate of this tank. Once in such a position, one should use the binoculars to scout for enemies without exposing the turret. If an enemy tank is spotted that could be a potential threat (dangerous tank / faced towards you) pop out a little bit and start to take out the enemies gunner/cannon barrel/cannon breech to prevent him from returning fire. Now utilize the quick reload to take out one crew member after the other to finish your opponent. If an enemy is spotted who is exposing their side or even the rear while not aiming towards you, shoot the engine first to immobilize and possibly even ignite the enemy tank, preventing him to take cover. The next shots should again disable the gun of the enemy, now finish your prey by shooting all crew members or if you feel lucky shoot an ammo rack.

The best choice to pierce enemy tanks is obviously the Shot Mk.3 (APDS) although it is quite expensive in terms of Silver Lions. The Shot Mk. 1 (APCBC) works in most situation as well but lacks penetration compared to the Mk. 3 APDS shot. The amazing penetration characteristics of this APDS shot enables this gun to pierce front plates of all Panther models (apart from the Panther II) to ranges up to 2000m. T-44s and Panther IIs front plates can be penetrated to ranges up to almost 1000m. Keep in mind though that the front plate of the T-44 is angled at 60°, so it bounces even this powerful APDS shot quite often. Even the front plate of the mighty Tiger II is not able to stop this APDS shot if not angled and the range is shorter than 100m.

In a head to head situation with an enemy tank approaching try to angle the centurion not more than 5° degrees to either side since the side armour is quite weak (50.8mm), try to hide your lower front plate which is a massive weak spot, while reloading turn the turret 10° to the right to maximize chances of bouncing shots (right side of the turret front has some extra armour) and keeping the gunner alive.

Pros and cons

Pros:

• Powerful and high penetrating gun, stock round is adequate enough to deal with other vehicle it faces.
• APDS is one of the best rounds for its BR, goes through the front of any tank you'll fight under 100 metres
• Can perform adequately even at higher ranks when APDS in unlocked.
• Plays exactly like the Centurion Mk 1, but can tackle a wider variety of foes due to a much powerful gun.
• Has a base reload time of 8.1 seconds, which can be lowered further into around 7.4 seconds (which is on average 2 seconds faster than its competitors).
• Excellent gun depression and elevation.
• Extremely strong gun mantlet.
• Somewhat bouncy armour(RNG), even more bouncy than the Mk 1.
• Gunner is on the right side of the tank, just like the Centurion Mk 1.
• Neutral steering, can turn on the spot without having to switch into gear 1.
• Good maneuverability.
• Like the Mk 1, the Centurion Mk 3 can fill the role of a heavy tank if needed.
• Good reverse speed.
• Gun stabilizer.
• Top (Roof) armour is resistant to aircraft guns.
• Front ammo rack can be emptied by carrying only 33 rounds.

Cons:

• Low top speed.
• Only has 10 degree of depression compared to 12 degree of the Centurion Mk 1.
• Ammo rack in the front, penetration through the lower glacis will likely ends up destroying or detonating the ammo rack.
• Top armor covering the engine compartments is not improved from the Mk 1, still 8mm which can be penetrated by most aircraft guns.
• Small internal compartment (only 4 crew members), easy to one shot.
• Centurion is a large tank = larger target.
• Carrying only 33 rounds might reduce the chance of getting your ammo detonated, but it will also decrease your combat effectiveness, especially in prolonged battles.
• APDS shot causes only punctual damage (aim carefully).
• No explosive filler on any AP shells.
• Weak side armour, do not angle the hull to much.
• Top of the engine deck can be easily penetrated by machine gun rounds.

History

Development

The tank's concept was made in 1943 when the Directorate of Tank Design, under Sir Claude Gibb, was asked to produce a new heavy cruiser tank for the General Staff under the designation A41, which was to become the standard of a British "Universal Tank" to replace the separated "infantry" and "cruiser" tanks currently used. As World War II progressed and the Germans unveiled their heavier tanks with an 88 mm cannon like the Tiger, War Office made a revision to their design requirements to counter this threat. The requirements now include an increased durability and reliability, with the ability to protect itself against the 88 mm gun and mines, an agility similar to the Comet tank and with good reverse speed, all while staying under a 40 ton weight.

Responding to these requirements, the department developed a larger hulls by adapting the suspension on the Comet, lengthening with another road wheel and spacing between the wheels. The standard Christie suspension used on the previous cruiser tanks was replaced by the Horstmann suspension, which uses coil springs on two-wheel bogies on each side and is proven to be easier to maintain than the Christie suspension. The hull used a welded and sloped armour with a cast turret mounting the famous 17-pounder cannon. The speed of the tank would be established by using the Rolls Meteor engine previously used on the Comet and Cromwell. Despite these changes, the department concluded that the weight restriction would not allow the tank design to withstand the 88 mm rounds. The weight restriction was done so the tank would be able to be carried around in the Mk.I and Mk.II transport trailers, which had a 40-ton load. This restriction was rescinded to allow more freedom in the tank design, which showed potential to War Ministry. The heavier tank designs developed had armour equivalent to the heaviest infantry tanks like the Churchill tank, yet with superior cross-country mobility due to improved suspension and engines.

The tank was given the name Centurion and the first mock-ups of the design was made by AEC and was presented in May 1944. After that, 20 pilot models were ordered with a various armament combinations. Ten had a 17-pounder and a 20 mm Polsten gun (5 with a machine gun in turret rear, 5 with an escape door instead), five had a 17-pounder and a BESA machine gun and an escape door, five more with the 77 mm HV gun with a driver operated hull machine gun. The prototypes of the 40-ton design, the Mk.1, had a 76 mm armour on the front glacis, which was made very powerful with the heavy sloping design on the tank. Added with a 152 mm thick turret armour, the Centurion became a very protected tank design, yet it was also very agile, outperforming the Comet tank in tests. The next Centurion model, Mk.2, featured a much thicker 118 mm front glacis armour and a thicker side armour. Production began for the Centurion Mk.2 in November 1945 for 800 tanks from Leyland Motors, Royal Ordnance Factories, and Vickers. The Mk.2 was put into service in the 5th Royal Tank Regiment in December 1946.

After the Centurion Mk.2 was put into service, Royal Ordnance developed the successor to the 17-pounder, the 84 mm 20-pounder. With this, the Centurion went through another upgrade to mount the 20-pounder. The 20 mm Polsten gun was removed and replaced by a BESA gun due to its questionable utility. The new upgrade, now the Centurion Mk.3, also featured an automatic stabilization system that improved firing accuracy while on the move. The tank was first produced in 1948 and overtook the previous Mk.1 and Mk.2 in service. However, the 20-pounder also did not stay in service for long and were replaced by the more powerful 105 mm L7 gun from Royal Ordnance Factories. All Centurions versions after Mark 5/2 used the L7 gun, including the Centurion Mk.10, which also featured additional armour with the new gun.

Combat usage

The Centurion first saw combat in the Korean war in 1950 in the British 8th King's Royal Irish Hussars. The Centurion Mk.3 issued to them had to be cared for in the winter conditions of Korea. Steps such as parking the tank on straw, starting the engine every half-hour, and keeping the gear engaged has to be done to keep the tank from becoming frozen in place. The Centurions made a great impact in the battlefield, covering the withdrawal of the 29th Brigade. In 1953, the Centurion saw part in the battle of the Hook in the 1st Royal Tank Regiment, repelling the swarming Chinese infantry. General John O'Daniel from the US 1st Corps praised the Centurion's mobility throughout the mountain terrains.

After the Korean War, the Centurions saw service again during the Vietnam War in the Royal Australian Armoured Corps after complaints were made on the thin armour of their armoured vehicles. The Centurions landed on 28 February 1968. Headed by Colonel Donald Dunstan, he ordered the Centurions to reinforce firebases at Coral and Balmoral. The use of the Centurions by the 1st Australian Task Force helped them in the Battle of Coral-Balmoral that caused massive casualties in two infantry regiments among the enemy with no known tank losses. After the battle, more Centurions landed into Vietnam, with a total of 58 Centurions in the country at once in the span of three and a half years. In this time period, 42 suffered damages, two were written off, and two crewmen were killed in action.

The Centurions also made up the bulk of India's tank forces, to which they used against Pakistan in the conflicts that occur in 1965 and 1971. In the middle east, the Centurions were supplied to Israel and Jordan in the 1950s. At the time of the Six-Day war, Israel had 293 Centurion tanks and Jordan had 90 Centurions. Both countries used the Centurions against each other in the war. Sometime in early 1970s, the Centurions on both side were upgraded with the 105 mm L7 gun. Both Jordan and Israel used the Centurion again in the 1973 Yom Kippur War, where the Israel establish the Centurion's prowess in battle during the Battle of Golan Heights, where 100 or so Centurions are able to beat back 500 or more Syrian T-55 and T-62 tanks. While the Centurion still see use in Jordan today, the Centurions in Israel were retired in the 1990s, only staying as armour personnel carriers and armour recovery vehicles. In the middle east, the British used the Centurions again during the 1991 Gulf War against Iraq, though only as an AVRE in the 32 Armoured Engineer Regiment. Three were lost in training incidents with no deaths among the crew.

Sweden and South Africa also used the Centurions, buying them from Britain after World War II. The Centurions in South Africa were retained and upgraded due to their superiority over anything their neighbors had at the time, with a focus on the upgrade to the 105 mm gun and belly armour to protect itself against mines. Sweden bought the Centurions in an attempt to standardize their tank forces as it was the most cost-effective method, plus the Centurions have a huge upgrade potential to counter future threats. The British offered to sell the Centurion in late 1952, to which 80 were ordered by Sweden. The first deliveries were made in April 1953, followed by more orders and more deliveries until about 350 Centurion tanks ranging from Mk.3, Mk.5, and Mk.10 were in Sweden. The Swedish military used the Centurions until 1990s, modernizing the tanks with upgrades in equipment and internal mechanics. They replaced the Centurions with Leopard 2s.
