A fighting vehicle that needs no introduction – The M1 Abrams is one of only a small number of tanks that have gained such a reputation and worldwide fame that surpasses legendary status by a long shot. War Thunder tankers and fans of modern military vehicles rejoice! The M1 Abrams is charging at full speed to the top ranks of War Thunder’s ground battles with the upcoming update 1.77 “Advancing Storm”. Get ready!
Once the unsuccessful joint German-American MBT-70 project had been shut down in 1971, the Congress redistributed funds to the further development of the XM815 project, later known as the XM1 Abrams. The development of the XM1 Abrams was a competition between two designs of the Chrysler and General Motors companies, respectively. Early July 1973 marks an important date for the project after representatives of both companies travelled to Great Britain to witness the development of the new composite armor, named Burlington. Impressed by what they saw, both companies decided to reevaluate and optimize their designs’ armor layout to increase its effectiveness, with General Motors changing the front shape of the turret to a sloped surface, whilst Chrysler retained its vertical design. By 1976, the XM1 prototypes were being readied for testing, with the finishing touch being the installation of the M68 cannon.. Testing of both prototypes took place in the presence of the new German Leopard 2 tank, which was shipped to the U.S. for comparison purposes. Once testing was concluded and the results evaluated, the turbine-powered Chrysler design was proclaimed the winner of the competition and thus the Chrysler design would soon enter production as the M1 Abrams.
The M1 entered production in 1979, with the first production version M1 leaving the factory floor in February 1980. Production of the M1 continued until 1985, with an improved M1IP version being produced briefly between 1984 -1986. By 1985, several thousands of M1s had already been manufactured and put into service. In August 1985 however, the M1 was outfitted with the licence-built version of the Rheinmetall 120mm gun, as found on the Leopard 2 tank and subsequently entered production as the M1A1 Abrams. Following this modification, earlier M1 units would progressively be upgraded to M1A1 standard, but this is a story for another devblog in the future. The M1 Abrams saw the most active service with US forces primarily in operations in the Middle East, but known operators also include Australia, Kuwait, Saudi Arabia, Egypt and others. Nonetheless, the American M1 Abrams is one of the most successful and widely fielded modern-day MBTs in use anywhere in the world, and rightfully deserves its iconic status alongside other American legends such as the M4 Sherman and M60 Patton, to name but a few. The fact that the M1 Abrams is still being manufactured and used today, almost four decades after its introduction, serves as a testimony to that statement.
In War Thunder, the M1 Abrams is going to be a new addition, that will expand the roster of vehicles available to players at rank VI of the American ground forces tree. Despite its enormous size and impressive combat weight of 60 tons, the M1 Abrams can hardly be considered a lumbering beast. Its 1,500 horsepower multi-fuel turbine engine is able to bring the Abrams up to a top speed of 45 mph ( 72.4 km/h) and even manages to achieve 25 mph (40 km/h) in reverse. With mobility like this, the Abrams is able to swiftly maneuver into position and even relocate to other locations on the battlefield at a moment’s notice. Apart from the excellent mobility, which is an offensive capability in its own right, the Abrams is also outfitted with a powerful main cannon and a pair of machine guns. For the primary armament, American engineers choose the 105mm M68A1 cannon, capable of firing a wide range of ammunition types. In addition to the cannon, the Abrams is also equipped with a coaxial 7.62mm machine gun, one more 7.62 is mounted near the loader’s hatchet and a good old .50 cal is mounted on the roof of the turret for anti-air defence.
Aspiring M1 commanders can expect effective protection against some of the most commonly used projectile types found on the higher ranks. However, it’s worth noting that all of this effective armor is mostly placed around the front portion of the vehicle’s hull and turret, as is common for modern MBT designs. In comparison, the side armor is relatively thin and can easily be pierced even by cannons of lower ranked vehicles. As the M1 Abrams was specifically developed with crew protection in mind, it comes to no surprise that several special protection features found their way onto the M1’s design. Fuel tanks in the front of the hull were placed in armored containers, that prevent fire in the fighting compartment and the fuel served as additional protection against HEAT shells as well. One more solution that provided better crew survivability was separate ammunition storage that was also in armoured containers. In cases where the powder charges were on fire, gas pressure was released through special blow-out panels that were mounted on the turret and the hull. Such system, if the panels functioned properly, would allow the crew to wait out the fire in the ammunition storage whilst remaining inside a tank, and after the fire was out, the crew could either leave the tank or drive it away from the battlefield.
