I would imagine some of the weapons in eve must have some seriously immense firepower. I mean even the explosive version of the weakest missile in the game "Phalanx Rocket" is described as wielding a small nuclear warhead.

Even the cruiser sized heavy missiles have to be multi-megaton warheads easily capable of leveling cities.

Even the torpedo arsenal of 1 Raven would be capable of leveling an entire planet with warheads ranging in the hundreds of megatons.

And never mind sieged citadels. They would probably be multi-gigaton warheads. The soot from 1 salvo alone would probably be enough to render an entire planet uninhabitable.

The other "non-missile" weapons would be harder to measure though. I would imagine they'd be much weaker in actual yield but much more focused "rather then having most of the blast get directed into space"

While it's true that any sufficiently advanced technology shall be indistinguishable from magic- and I should avoid making absolute pronouncements, I think it's safe to say that there's certain things that just won't work unless the laws of physics change.

I mean, we know now that the universe isn't truly newtownian, but actions have reactions, and the amount of energy required to accelerate an object is going to produce an effect by the platform doing the acceleration. There's a practical upper limit to the mass of any object you can move or the amount of energy you can impart to it, simply because past a certain point you'll push yourself away or more likely, destroy your ship. ;)

True, but I think we need to take into account advances in technology and our understanding of the laws of physics to make those limits a little easier to push. Not unlike the concept of heavier-than-air flight in the late 1800s.

I need to find someone to crunch the numbers on how much energy would be required to launch a 1400mm projectile fast enough to reach a target 50km away at a speed so fast that a human being couldn't detect any lag between shot and impact. That would be useful for determining how much mass the firing platform would require and how strong the projectile would have to be in order not to be reduced to plasma.

The human bran can generally detect and react to 1/4 of a second intervals. Based on what a previous poster said, the projectile in question would weigh approximately 120,000 pounds, or about 55,000 Kilograms
50KM in .25 seconds = 200KM/second = 720,000KMH

So does anyone know the amount of energy it would take to accellerate a 55K Kilogram shell to 720K Kilometers per hour? I'll do the calculations myself if someone can point me towards the correct formula.

It would also be interesting to know if the artillery shells in question have propellant of their own to perhaps aid in the acceleration. Hrm.

I may not remember the formula or be using the right one, but here's what I got:

E = 1/2mv^2

0.5 * 55000 * (200*1000)^2 = 1,100,000,000,000,000 joules = 1.1 petajoules

1.1 petajoules is made by approximately 7,722,953.55 US gallons of jet fuel.

Anyone care to turn that into output per hour for the average nuclear power plant?

"1.1 petajoule! What the hell were I thinking?!?"
"Relax Doc, all we need is 7,722,953.55 US gallons of jet fuel."
"I'm sure that in the Eve-region you come from you can just buy jet fuel in any station, but here in Solitude it's a comletly different story!"

i'd be more afraid of railguns than of anything you shot out of a projectile weapon... the reaction between matter and antimatter is a hell of a lot more energetic than any nuclear reaction, so a 425mm charge full of the stuff would probably make your volkswagen-sized nuke look like a popgun...

because its not an explosion per se, its an expanding sphere weapon emitted from the ship

1/20th of a second is the perception threshold for humans. Anything faster will seem simultaneous. Reaction times vary a good bit.

just to add, ive heard alot of people say the 1400mm would be a small car...
the US battleships hurled shells the size of a voltswagon.
so a titan would be like firing a 4 story building. just a guesstimate.

Yamato class
Country: Japan
Displacement: 65,000 tons
Armament: 9 x 460 mm (18.2 inch) guns, 12 x 155 mm guns, 12 x 127 mm guns, 24 x 25 mm AA guns, 4 x 13 mm AA guns
Aircraft: 2 x catapults with 7 x seaplanes
Armor: 410 mm belt, 200 mm deck, 650 mm turret
Speed: 27 knots
Range: 11,500 km at 16 knots
Ships in class: 3: Yamato, Musashi, and Shinano
Commissioned: 16 December 1941
Fate: Shinano converted to an aircraft carrier, Musashi sunk 1944, Yamato sunk 1945

The bismarck had 15 inch guns, modern day BSes have 16 inch guns. these are not muzzles a volkswagon can fit in. even the yamamoto, which had HOOOG guns is only half a metre wide.

you MIGHT JUST fit a volkswagen in the 1400MM range, but no WAY do battleships, modern or ancient, fire 1400MM shells.
