My figures on the cost (electric usage cost) was based on random things I've read defending the cost of development that will eventually offset the cost of conventional arms. I would imagine it would cost more than $1 in electric per shot, but since they use their own generators and don't pay all the fees we civvies do, who knows? I wasn't factoring in other costs since most articles supporting rail-gun tech talk about how wonderful the low-energy costs are.
Though it may not scale literally infinitely, it can scale up to such a rate that we don't can't really quantify it atm. Materials science and power generation and storage are current issues, but all change and evolve over time to end results we can't currently predict.
I do remember old rail-gun proto-types I read about from the 80's showing proof of concept and that it could be a functional weapon in the future, and I'm very happy to see we're finally getting there. I'm also glad to hear bureaucracy stays out of the super-high-end research area.. since most politicians can barely work the internet and sound like absolute stooges when speaking in public about anything tech related.
My cost estimates from random things I remember reading over the years aren't that far off either. With a 10 year period to look at with ~$10-20mil/year I suggested, and actual costs coming up at $240mil over 10 years, that's pretty good. Costs of $24mil/year are very acceptable for such a useful device.
Sure, I could have Googled for more specific figures, but I didn't realize /. rules were coming into effect here where everything had to be spot on and every thread was a 'serious discussion'. If we really wanted to discuss the OP, we could talk rail-guns singularly... short and simply discussion since they operate off a relatively simply concept. :\

Don't forget the benefit of not having a ship full of explosive ordinance like missiles and large caliber bullets. A fire near a conventional ammo bay would be catastrophic, but a fire around some inert metal slugs with no payload? Much less of a crisis.

It's a win/win/win, they have been working on railgun tech for decades for a reason.

This. Heck, I built one in AP Physics the other day biggrin.gif

Sounds like they need to develop a new type of destroyers. Actually, more like a new class of nuclear powered battleships armed with a couple of these high powered railguns as their main armaments.

Only a nuclear powered battleship would be able to bring an array of these to full potential thumb.gif

Yes, they were replaced by aircraft carriers and destroyers. However, if you've got a huge "nuclear" destroyer with many of these railguns it's no longer a destroyer sized ship....wouldn't that be more of a battleship than a destroyer? biggrin.gif

A railgun platform essentially a mobile a seige device that can hit targets of over 100 to 200 miles. That'll replace the need of many surface to surface missles. At $25,000 per shot instead of 1.5 million for the tomahawk cruise missile, it might make sense to consider this.

One aircraft carrier and battleship seige vessel per fleet with a few aegis missile defense ships? tongue.gif

Yes. This tech could very well bring back the 'battleship.' Big ships with big guns.

BTW, guided missile cruisers and Carriers were the death of the old battleships.
