The Pentagon has been intensively developing railgun technology for several years. For the purposes of testing, weapons are prepared by defense companies: General Atomic and BAE Systems. The American electromagnetic weapon consists of a 155-millimeter cannon that fires 10 rounds per minute with an energy of 32 megajoules and a speed of 9,200 km / h without any problems. Ultimately, the devices are to be capable of hitting targets up to 200 kilometers away at speeds of up to 6,000 km / h.
A few days ago, more tests of this All About Movies were carried out on the Potomac River in Virginia. Residents talked about very loud explosions coming from the basin. Unfortunately, this is one of the two drawbacks of this weapon. The second is to provide a powerful dose of energy that is needed to fire a shot. However, this problem was solved. The new destroyers are equipped with highly efficient generators and batteries that can easily store and supply the necessary energy to the kinetic guns.
The interest of Americans and Chinese in this technology is related to the fact that this weapon is a much cheaper and more effective means of fighting enemy ships, missiles and ballistic missiles than the traditional missiles used for this purpose. According to experts' estimates, the cost of a single railgun shot will be around $ 25,000. Meanwhile, the use of conventional missile weapons costs at least 40 times higher.
With the help of laser and electromagnetic cannons, the US wants to significantly increase its, and so great, advantage at sea in the face of China's recent activities that concern the entire world. Recall that the Middle Kingdom claims the rights to the islands in the South China Sea. The countries there are not able to face China militarily, which is why the Pentagon began to take serious interest in this part of the world.
