The Navy has spent seven years testing out the components of a way-futuristic weapon: a shipboard cannon that blasts bullets over vast distances at hypersonic speeds using bursts of electricity. ... The Navy released video of the first tests, viewable above, on Tuesday. The dramatic mini-inferno in the wake of the slug fired from the railgun is the result of “1 million amps flowing through” the gun, said test chief Tom Boucher, the hypersonic speed of the shot, and the actual aluminum of the bullet — “reactive in the atmosphere” — burning off.

The gyrojet pistol (video) - a handgun firing 13mm rocket ammunition, was an attempt to revolutionise gun design in the 1960s. Around a thousand were produced, and some may have seen use in Vietnam. Rifle and carbine versions were also produced. Design problems meant that it never seriously competed conventional firearms, but there is a modern attempt to revive the concept.
