The Navy set a new world record for the most powerful electromagnetic railgun when it fired a test shot here Thursday morning.
The gun fired an aluminum projectile at 10.68 megajoules. A joule is the work needed to produce one watt of energy for one second. A megajoule is 1 million joules.
The Navy plans to build 64-megajoule guns. If they can, maybe we’ll actually have some decent naval fire support again.
