it's been a big 24 hours for the US weapons-tech establishment in terms of making stuff go really fast. American war-boffins shot a railgun slug with ten megajoules of muzzle energy (and speed of Mach 7+) yesterday; a different weapons lab has also broken the world land speed record.
The new benchmark - with reference to unmanned vehicles running on rails, anyway - was set by a team at the Holloman Air Force Base High Speed Test Track in New Mexico. This facility is used by the American forces to test all sorts of stuff: ejection seats, missile prototypes, bunker-penetrating warheads etc.
