![]() Rail guns may bring back heavy cruisers but not battleships. The projectile is carried down the “barrel” on a series of rails via a force not unlike linear induction (on steroids). A railgun does not have a traditional barrel. It weighs about 30 pounds and can hit targets up to 2,000 yards away with armor-piercing bullets. ![]() 50-caliber rifle created by Ronnie Barrett and sold by his company, Barrett Firearms Manufacturing Inc., is the most powerful firearm civilians can buy. What is the most powerful gun in the world? Thereafter, the electromagnetic railgun can toss the material into space. If astronauts can station at the moon and mine resources, the said speed is just a fraction “slower” than the escape velocity. Can a railgun fire in space?Īccording to Space, the electromagnetic railgun peaked at Mach 6, which means six times the speed of sound. ![]() A helical railgun was built at MIT in 1980 and was powered by several banks of, for the time, large capacitors (approximately 4 farads). They do not currently exist in a practical, usable form. The Navy is instead pursuing an offshoot of the railgun, a hypervelocity projectile it can fire from existing gun systems. Navy’s $500 million electromagnetic railgun-capable of slinging projectiles at hypersonic speeds-lacks funding and has no coherent plan to deploy on warships.
