Rail Gun
Feb 3rd
[html] This is a new "rail gun" the US navy is testing on one of their ships..It uses a electromagnetic field pulse to shoot a projectile over 200 nautical miles… It takes 3 million amps to shoot his thing for each projectile..The kinetic energy of a solid projectile hitting something at this speed is equal to a cruise missle hitting it, but a lot cheaper to use…
The average ordinary 15 inch gun now can only shoot around 15 nautical miles… The energy needed to shoot the solid projectile at mach 8 is around 32 megajoules… Its calculated to shoot this gun
6 times per minute the ship will have to supply 16 megawatts of power…They want to achieve a goal of a 64 megajoule weapon which would take a staggering 6 million amps to shoot…
They still need to develop a breakthrough in material construction so that the guns themselves won't be shreaded by each high velocity barrage…

[html] Thought people might be interested in reading some of these facts on Ham Radio. Â I've added it to the links as well so it can be found after this news item is archived. Â Its kind of an Frequently Asked Questions (FAQ) which I think would be a good addition to this site for new hams to find out more about what amateur radio is all about.
