DailyTech: BAE Sports Most Powerful Railgun Ever
"BAE's new BFG 32-megajoule railgun annihilates its competitors
Earlier this year General Atomics, a rival research company, demonstrated a 8-megajoule railgun, which fired shells at Mach 7. Until now 9-megajoule railguns were the most powerful models in existence.
BAE is looking to blow these "peashooters" away after it announced a railgun four times more powerful. A functional prototype of its railgun has been delivered to the U.S. Naval Surface Warfare Center in Dahlgren, Va. and is currently being installed at the Center.
Incredibly, the device is only the initial offering from BAE. It hopes to soon meet the Navy's goal of a 64-megajoule weapon capable of being mounted on a warship. Such a weapon would draw a current of approximately 6 million amps. With such high power requirements, such a design is technically feasible when placed on a nuclear-powered vessel.
Such a cannon would be able to fire at speeds in excess of Mach 7 at targets as far as 220 miles away using cheap metal slugs. Such a cannon could unleash a silent deadly barrage that would hit the enemy harder and would give less warning than a traditional missile strike."

Who needs friggin Lasers, surprised the air resistance doesnt melt the projectiles on route...

Mach 7 shell? 220 Miles? Imagine trying to calculate the effects of wind currents on that thing over that distance 
Amazed they could lob huge bits of metal that far accurately

Pritty amazing stuff, i remeber when that guy built the lil one and shot an apple with it, now this.... 220 miles?! daaaaaaamn. It will be who ever see's the enemy first insta wins!

220 mile range, thats amazing for just slugs, there'd be no way of stopping them if you managed to spot them  _________________

if the wind speed was a constant 10 mph crosswind it'd knock you off target by over 2/3 of a mile over a full 220 miles shot. its not going to be accurate, its unguided.
that's all based on a rather rudimentary approach to particle kinematics, but it seems unlikely it'll just fly in a straight line....

Sounds to me like a similar problem in sniping, hitting pinpoint accuracy with a piece of metal over a huge distance with a lot of enviromental factors, although of course on a much grander scale.
Well they have that down to a fine art on the field with simple equipment.
I'm sure on a nuclear powered battleship the calculations needed to aim the damn thing wouldn't be much of a problem for the onboard computers and gunner team. In my opinion anyway. _________________
