A 32 megajoule railgun shot is equivalent to about 23,600,000 foot-pounds, so a single 32 MJ shot has the same muzzle energy as about 200,000 .22 rounds being fired simultaneously. [99] In more conventional power units, a 32 MJ shot every 6 s is a net power of 5.3 MW (or 5300 kW).

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 ...
In comparison, a railgun currently cannot achieve a higher muzzle velocity than the amount of energy input. Even at 50% efficiency a rail gun launching a projectile with a kinetic energy of 20 MJ would require an energy input into the rails of 40 MJ, and 50% efficiency has not yet been achieved. [19]
BL 9.2 inch (233 mm) Railway Gun c 1900. Railway guns were large guns and howitzers mounted on and fired from specially constructed railway cars. They have been obsolete since World War II and have been superseded by tactical surface-to-surface missiles, multiple rocket launchers, and bomber aircraft.
The design of a railway gun has three firing issues over and above those of an ordinary artillery piece to consider. Namely how the gun is going to be traversed – i.e. moved from side to side to aim; how the horizontal component of the recoil force will be absorbed by the gun's carriage and how the vertical recoil force will be absorbed by the ground.
The CCEMG launcher (version III) was a series augmented railgun capable of firing three five-round salvos of 185-g launch packages at a velocity of 1,850 m/s with a firing rate of 5 Hz. It was a 2.25 m long, water-glycol cooled launcher with a 30 mm rectangular bore and achieved rapid fire operation with the help of a CCEMG compulsator that ...
