Ep 3. US Army's Super Tank

Impossible Engineering is a series that showcases the most extraordinary feats of engineering and construction around the world. In season five, episode three, titled US Army's Super Tank, the show takes a closer look at the creation of the Abrams M1A2 battle tank and the engineering challenges that were overcome during its design and development.

The episode begins by introducing the Abrams tank, which was first produced in 1980 and has since become one of the world's most advanced and formidable armored vehicles. The tank is a product of a collaboration between the US Army and the defense industry, with General Dynamics Land Systems being the lead manufacturer.

To understand how the Abrams tank has become such a powerful vehicle, the show takes a look at the tank's design features and explores the cutting-edge technology that makes it so effective on the battlefield. The first challenge in creating the tank was to design a powerful engine that could move the heavy and bulky vehicle through rough terrain. To accomplish this, designers turned to the gas turbine engine, which was developed by the aviation industry. The gas turbine engine allowed for a higher level of power and speed while maintaining a compact design. However, the team also had to contend with the added risk of a fuel explosion. After many years of collaborative effort, the final product was a gas turbine engine that could propel the tank at speeds of up to 42 miles per hour and over 15 tons of iron.

While the engine was crucial to the success of the Abrams tank, its protective capability was equally important. To ensure the safety of the tank's occupants in combat situations, the designers had to create an impenetrable armor. However, creating such a strong armor was a challenge, as any added weight could reduce the tank's speed and mobility. Engineers decided to use reactive armor, which, in an explosion, would decrease the force of the incoming projectile and deflect damage. The reactive armor held up well in explosives tests.

Another technological breakthrough that the show highlights is the tank's computerized fire control system, which enables the gunner to fire the main gun with a high level of accuracy and precision. The system takes into account a range of factors, such as the tank's speed, range, wind direction, and the target's movement, to ensure that the gun is fired at the right time and angle to hit the target with lethal accuracy. This advanced system allows the gunner to hit a target from miles away with a single shot, eliminating the need for multiple rounds.

The show also explores the manufacturing processes involved in the creation of the Abrams tank, which is a highly complex process requiring a wide range of specialized skills. 30,000 people were involved in the making of the tank. Robotics and automation allow some of the complex tasks to be automated to ensure precise assembly, and ensure the safety of the manufacturing workers.

Overall, this episode of Impossible Engineering is a fascinating exploration of the creation of the US Army's super tank, the Abrams M1A2. Viewers will come away with a new understanding of the engineering challenges involved in creating such a formidable vehicle, as well as an appreciation for the technological breakthroughs that make it possible. From its powerful engine to its advanced computer systems and impenetrable armor, the Abrams tank is more than just a vehicle; it is a testament to the power of engineering and design.
