The US Naval Research Laboratory has built an electromagnetic launcher facility to study sliding contact physics and support the railgun program run by the Office of Naval Research. A railgun uses electricity instead of gunpowder to fire a projectile at several times the speed of sound at a target. A railgun is an ideal weapon platform for an electric ship, as the same energy source that drives the ship can be used to power the railgun. This video shows the complete firing process, including loading the gun, firing, assembly/disassembly, and changing the catching apparatus. APPROVED FOR PUBLIC RELEASE. ONR CASE NUMBER 43-312-10.

  • The funniest part was when they opened it up by unscrewing those thousand plus nuts, then immediately screwed them all back on. High drama down at the lab, all right. Oh, and great choreography too. Take that, Tchaikovsky!

  • @wolfy9005 Heh, not being new to the game, I'm well aware of it. It just struck me as an amusing comment. I'm (slowly) working on my second bench-scale conventional railgun myself. (1m, ~20kJ)

  • I want to make same one at my home!

  • @railgap Basically. If you look at the barrel(armature?) of most railguns, it's just a whole line of bolts holding the whole lot together. Jammed inside? Unscrew all the bolts. Copper wearing out/needing replacing? Same story.

  • how many shoots per rail change??

  • Also: someone in a pulsed power lab somewhere said, "pulsed power is all about tightening (or loosening) bolts, LOTS of bolts, over and over and over..."

  • Ah, nuts! We don't get to see the bore/liner structure!

  • The real question is who is slacking on work?

  • thats at my dads work :)

  • @RAHMELBASS no wiem ale powiedz mi czemu tam kurwa tyle ognia jest przy strzelaniu ... jak by używali prochu to bym zrozumiał
