Railgun in real life.

Our Tanki Railgun doesn't bear much similarity with the real one except the long barrel/cylinder. But their objective is the same, to destroy! Also the real Railguns are to big to equip on tanks. So it is only used by the navy in large battle ships.

The Railgun is made up of mainly three parts: Power source, parallel conductive rails and the projectile. Here's how it works. An electic current runs from the positive terminal of the power supply, up the positive rail, through the metal projectile and down to the negative rail back to the source. Due to this event a magnetic field is created in the two rails that forces the projectile forward.

The US navy tested a Railgun that is able to accelerate a bullet of  3.2 kg at a speed of  2.4 Km per second! That equals to 5400 miles per hour! That kind of power is very hard to supply. In order to launch all the power of the engine is diverted to the turret. The ship cant move until the gun is turned off.

pointless topic

Every topic, if interpreted correctly, can evoke interesting discussion. There's no such thing as a pointless topic, so don't make yourself a fool by posting that.

railgun is an electrically powered electromagnetic projectile launcher based on similar principles to the homopolar motor. A railgun comprises a pair of parallel conducting rails, along which a sliding armature is accelerated by the electromagnetic effects of a current that flows down one rail, into the armature and then back along the other rail.[2]


Railguns have long existed as experimental technology but the mass, size and cost of the required power supplies have prevented railguns from becoming practical military weapons. However, in recent years, significant efforts have been made towards their development as feasible military technology. For example, in the late 2000s, the U.S. Navy tested a railgun that accelerates a 3.2 kg (7 pound) projectile to hypersonic velocities of approximately 2.4 kilometres per second (5,400 mph), about Mach 7.[3] They gave the project the Latin motto "Velocitas Eradico", which is Latin for "I, [who am] speed, eradicate", but may have been intended as "Speed kills" or similar.


In addition to military applications, railguns have been proposed to launch spacecraft into orbit; however, unless the launching track was particularly long, and the acceleration required spread over a much longer time, such launches would necessarily be restricted to unmanned spacecraft
