What Was The First Main Battle Tank?

Everyone is enquiring as to What Was The First Main Battle Tank? The Centurion (A41) was the dominant British First Main Battle Tank in the post-World War II period, having debuted in 1945. For decades, it was a successful tank design with upgrades. The chassis was also repurposed for a variety of additional purposes.

What Was The First Main Battle Tank?

The British unveiled their Centurion A41 as the first real Main Battle Tank in 1945. The Soviet Union’s traditional T-54/T-55 lines and the United States’ M60 “Patton” then presented rival designs in response.

The First Main Battle Tank

The Centurion’s development started in 1943, and production began in January 1945, with six prototypes arriving in Belgium less than a month after the European war had ended in May 1945. It originally fought alongside the British Army in support of UN forces in the Korean War in 1950.

The Centurion went on to serve with the Australian National Armored Corps in Vietnam, where it battled against US-supplied M47 Patton and M48 Patton tanks during the Indo-Pakistani War of 1965. Centurions Tank was employed by Israel in the 1967 Six-Day War, the 1973 Yom Kippur War, and the Lebanon invasions of 1978 and 1982.

In Gaza, the West Bank, and along the Lebanese border, Centurions were adapted as armored personnel carriers. During the Black September events in 1970, the Royal Jordanian Land Force utilized Centurions to ward off a Syrian assault within its boundaries, and later on the Turkish Border in 1973.

In Angola, South Africa utilized its Centurions. It was among the most commonly used tank designs, with several still in service in armies around the world in the 1990s. The Israel Defense Forces used significantly modified Centurions as armored military vehicles and combat construction vehicles as recently as the 2006 Israel-Lebanon conflict.

The SANDF’s vehicles were updated in the 1980s, and the resulting type is called as the Oliphant. South Africa still utilizes approximately 200 Centurions. During 1946 and 1962, a total of 4,423 Centurions were manufactured, with thirteen basic marks and various modifications.


Mark 1

The ultimate weight was 42.5 short tons (38.55 metric tons), beyond the required limit by two and a half short tones. 11 kg /cm2 was the ground pressure. This was owing to the understanding in the latter development phase that providing sufficient armor protection against a direct hit from a German 88 mm (3.46 in) within the weight constraints was unachievable.

The maximum load allowed by standard Mark I/II transport trailers was used to set these restrictions. When it became evident to the War Ministry that these constraints could not be met without significant performance losses, a new transport vehicle was designed and the limits were raised.

The final design included a 3 in (76 mm) thick armored glacis with a well-sloped armored glacis. This was an improvement over the earlier Cromwell and Comet, but it was still superior to Churchill’s 101-150 mm (3.98-5.9 in) or even Matilda II’s 80 mm (3.15 in) prewar design.

Despite this, the effective thickness was substantially higher due to the glacis plate’s steep slope. Before manufacturing, the pilots underwent extensive testing, and the A41 was rapidly acknowledged as superior to the Comet, preceding cruisers, and any other British tank design to date, rendering the A43 Black Prince, a late attempt to produce an intermediate design based on the Churchill, obsolete.

That was the first effective attempt to create a real “universal tank,” ready to replace both the Churchill and the Cruiser tanks. Until 1945, just the pilots and a few manufacturing vehicles were built. In March-April 1945, three were deployed to Belgium for thorough trials near the front, but it was too late for any actions.

Mark II

The Mark 1 was a huge success, but in 1946, the threat of Soviet tanks drove the development of a more heavily armored version, the Mark 2, with a frontal plate thickness of 110 mm (4.33 in) and sides of 56 mm (2.2 in). A newly built completely cast turret was also included.

In November 1945, Leyland Motors, Vickers (Keswick), and the Royal Ordnance Factories at Leeds and Woolwich were asked to replace the Mark 1 on the production line. The 5th Royal Tank Regiment deployed the Centurion II in December 1946. All Mark 1/2s were converted to recovery vehicles or modified to the Mark 3 stand after being superseded by the Mark 3.

Mark III

The Ordnance QF 20 pounder (84 mm/3.3 in) was introduced in this variant, and it provided significantly higher accuracy thanks to a newly built completely automatic stabilizing system. This permitted the gunner to fire while moving, as per prewar British doctrines, but it was rarely effective.

The bullets were also significantly heavier, allowing them to penetrate the T-34/85 and IS-2/frontal IS-3’s armor. The T-54 was unknown at the time. The Polston 20 mm (0.79 in) machine gun was replaced with a significantly lighter standard 7.62 mm (0.3 in) Besa machine gun in the second upgrade.

The Polston was proved to be an unreasonably big caliber for dealing with normal infantry soldiers.On the glacis, there were also two stowage places for the track links. The Mark 3 was introduced in 1948 and had a higher manufacturing rate than the Mark 2.

They saw considerable service in Korea and proved to be slightly more effective in the battle than the M26 Pershing and M46 Patton, both of which were armed with 90 mm (3.54 in) guns.

Mark IV

The Mark 4 was a close-support version with a 95 mm (3.74 in) howitzer that was never used again after the concept was proven ineffective. The Mark 5, on the other hand, was a whole new level of Centurion advancement. It had a more powerful Meteor engine, as well as a redesigned gun sight and stabilizer.

On the coaxial and commander’s cupola mounts, Bradley machine guns were placed, while stowage bins were placed on the glacis. The Mark 5/1 (FV4011) had a thicker frontal glacis and a twin-arrangement of coaxial machine guns, 1.30 cal (7.62 mm) Browning and one heavy.50 cal (12.7 mm) with tracers, which were used to range the 20 pounders main armament.

The Royal Ordnance Factories’ latest cannon, the Mark 5/2, was launched. The L7 105 mm (4.13) gun is a well-known weapon. This new rifled gun was substantially longer (L/52 or 52 calibers) and had a bore evacuator in addition to the caliber. A horizontally sliding breechblock was used in the breach.

The L7 was developed after testing against the T-54A, of which only one was seized on “British land” – the British embassy in Budapest – driven there by its Hungarian crew after the 1956 revolution.

The improved US M60 and M1 Abrams, Germany’s Leopard, as well as Japan, India, Israel, and even China, adopted the L7 as their main battle tank gun. It remained in the British inventory’s first line until the replacement L11 (120 mm/4.72 in rifled) became available.


The above information is ended here about What Was The First Main Battle Tank? The Centurion (A41) became the dominant British Main Combat Tank in the post-World War II period after its appearance in 1945.

It was a popular tank design that had been updated for decades. The chassis was further modified for a variety of additional purposes. From 1943 to 1945, the Gladiator was built, with six versions arriving in Belgium less than a month after the European war ended in May 1945.

Frequently Asked Questions

Is it true that the US has never lost an Abrams tank?

553 Abrams tanks have been decommissioned. At least 14 of them were completely destroyed by enemy fire. During the Gulf War, 23 M1A1s were destroyed. This included 7 killed by friendly fire and 2 disabled aircraft destroyed (to prevent them from falling into enemy hands).

What is the most powerful tank that has ever existed?

According to a recent story, North Korea’s Pokpung-ho IV tank has the world’s greatest firepower. This would make it more formidable than any other tank, including the M1A2 Abrams from the United States and the T-90M from Russia. The North Korean tank, in actuality, has far less firepower than almost any other modern tank.

When did the Marines obtain their first tanks?

Marines died fighting tanks in the Corps’ early World War I iterations, but it wasn’t until the mid-1920s that the corps got its own tanks to play with, train with, and deploy.

In World War II, did the Marines use tanks?

The lessons learned during such man oeuvres would come in use later in World War II, when the Marines refined their amphibious assault tactics in the Pacific. The unit received two more tanks, one shotgun, and one cannon upon their return from Culebra.
