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 B53 wasn’t just any old megabomb. It was the first bunker buster. U.S. nuclear doctrine called for it to be delivered over suspected underground Soviet command-and-control facilities.

In 2015, if all goes well, the USS Gerald R. Ford, the most powerful warship ever built, will begin service in the U.S. Navy - retiring the venerable Enterprise (CVN-65). Though displacing the same 100,000 tons as her Nimitz-class counterparts, increased automation will let her operate with hundreds fewer crewmembers. Capable of launching 90 planes, including the F-35C Lightning II, on 220 sorties a day, she will defend herself against anti-ship missiles with the Raytheon RIM-162 ESSM. [more inside]
