This Is Why the Navy Can't Have Nice Railguns

​The US Navy has been wowing people with electromagnetic railguns, a long-range electrically-powered weapon, in concept and prototy​pe for years now. But the single big obstacle that keeps the railgun off boats remains the same as it ever was: ships can’t generate enough power to fire them. At the Naval Future Force Science and Technology Expo, Vice Adm. William Hilarides explaine​d that three problems with the railgun remain: room on ships, integrating the new weapons with the old weapons systems, and power—as in, not enough of it. The railgun doesn’t rely on chemical explosions like more conventional weapons. Instead, the projectile is housed in a electrically conductive metal armature, which connects two parallel, 30-foot rails. A huge 25-megawatt electric pulse is sent down the rails, creating the magnetic fields that shoot the armature and projectile out.

Oh, all they need is a wind turbine or solar panel and they could generate 25mw easily!

"...21st-century stealth battleship with electric engines, is powered by a 78-megawatt array of turbine generators. So, firing a rail gun once would take almost a third of the most advanced ship's whole capacity."

LOL!

I guess when the ship runs out of "Megawatts" it's dead in the water by this author's logic.

Here is a rail gun test fire

At 1:24 you can see the shock wave around the projectile
as it travels.

They could do that. (mW vs. MW)

New capacitor technology could solve this.

The word ‘can’t’ is the sticker.

People are really smart, and eventually can’t becomes can, in a free society at least.

we’re so broke we’ve resorted to using connecting rods for ammo!

And more so in the other kind, by necessity.

Where is all the flame coming from, if exposives aren’t involved in propulsion?

That reminds me of the wave motion gun, which is also terrifying.

I saw that video when it first came out, and calculated that the projectile oscillations you can see in the down range view (the one in which the shock front is so clearly visible) are at a rate of about 60 hz.

It's what's left of the arc that is formed across the rear of the projectile (or maybe across the entire projectile in this case) following it as it leaves the mouth of the launcher.

Total conversion via matter - antimatter interaction would get the job done.
