In 1944, during World War II, Joachim Hänsler of Germany's Ordnance Office proposed the first theoretically viable railgun. By late 1944, the theory behind his electric anti-aircraft gun had been worked out sufficiently to allow the Luftwaffe's Flak Command to issue a specification, which demanded a muzzle velocity of 2,000 m/s (4,500 mph; 7,200 km/h; 6,600 ft/s) and a projectile containing 0 ...
The U.S. Navy pulled the plug, for now, on a futuristic weapon that fires projectiles at up to seven times the speed of sound using electricity. The Navy spent more than a decade developing the ...
For comparison, the M16 rifle has a muzzle speed of 930 m/s (3,050 ft/s), and the 16-inch/50-caliber Mark 7 gun that armed World War II American battleships has a muzzle speed of 760 m/s (2,490 ft/s), which because of its much greater projectile mass (up to 2,700 pounds) generated a muzzle energy of 360 MJ and a downrange kinetic impact of ...
ETC requires much less energy input from outside sources, like a battery, than a railgun or a coilgun would. Tests have shown that energy output by the propellant is higher than energy input from outside sources on ETC guns. [18] In comparison, a railgun currently cannot achieve a higher muzzle velocity than the amount of energy input.
That such testing is both useful and necessary points up that a rifle is a system, and precision shooting perforce involves all components, as well as good shooting techniques. Benchrest remove only two factors, 1) the ability to precisely return a rifle to the same point of aim, and 2) to apply constant forces to the rifle from shot to shot.
The Heckler & Koch G11 is a non-production prototype assault rifle developed from the late 1960s to the 1980s by Gesellschaft für Hülsenlose Gewehrsysteme (GSHG) (German for "Association for Caseless Rifle Systems"), a conglomeration of companies headed by firearm manufacturer Heckler & Koch (mechanical engineering and weapon design), Dynamit Nobel (propellant composition and projectile ...

A plasma railgun is a linear accelerator which, like a projectile railgun, uses two long parallel electrodes to accelerate a "sliding short" armature. However, in a plasma railgun, the armature and ejected projectile consists of plasma, or hot, ionized, gas-like particles, instead of a solid slug of material. Scientific plasma railguns are ...
