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...

i could call that impressive,... :shock: :o 8) 8)


and 6 million amps? :shock: :o

Mach 7 shell? 220 Miles? Imagine trying to calculate the effects of wind currents on that thing over that distance :lol:

Amazed they could lob huge bits of metal that far accurately :twisted:

No really thats an amazing piece of work.

as if they didnt have enough problems with hitting targets as it is :roll:

who remembers the red cross building they bombed :lol: :lol: :lol:

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!

Negligble at Mach 7, surely?

yeh from my limited knowledge of physics i would think that the shell would be carrying so much energy that to alter its flightpath wouldn't be possible by simple wind?

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

its about 2 and a half minutes of flight time, so its travelling for long enough to be significantly affected by the wind....and over 220 miles the wind is going to change a lot....it'll be quite a challenge and it'd be interesting to see how they get over it....

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.
