Kerr : I seriously doubt tanks will run on nuclear power in the near future. But the time they do, then weapons technology will have evolved far beyond shooting each other with high velocity projectiles. Perhaps they'll just use lasers and call down missiles from arsenal birds to strike at over-the-horizon targets. Therefore, it makes sense to use conventional turbines as the basis for comparison for near future technology. If 1MW if what we've got, then the induction electrothermal gun will shoot one tank penetrating round every 10 seconds. If it's shooting lower velocity HE, it has a better firing rate. If it wants a long range tank buster, then it can charge a shot for 30 seconds or more. If power requirements are increasing, then a larger turbine might be installed. There's also the option of a hybrid gun. A chemical propellant provides some energy, induction heating provides the rest. Tactical use of the energy stored in the flywheels must also be considered. Tanks could spin up some 'ready energy' worth several shots before combat. This would allow one tank to take down multiple targets in seconds, after which is drives away to spin its flywheels back up. Currently, you need to coordinate an entire tank platoon to get that capability. Nice to know that you dont think tank will run on nuclear power in the near future either. I think it is unlikely that they ever be nuclear powered for several reasons. An Electrochemical gun would be the best option overall.

tanks don't need more firepower With the recent development of the Russian Armata tank, Western planners apparently disagree with this. Case in point, the future Lepoard 3 which is so far going to feature a quite larger calibre gun. It will be interesting to see if it will use an electrothermal gun, in fact. And with the chronic Russian musing with putting artillery-size guns on tanks, they also disagree with this.

And with the chronic Russian musing with putting artillery-size guns on tanks, they also disagree with this. This is Russians going the cost-effective route again. In naval warfare, they saw the US building multi-billion-dollar carrier fleets, and equipped themselves with much cheaper long range anti-ship missiles. In tank warfare, active defenses, composite armor and heavy hulls make tanks very expensive to build and run. Russia counters with a bigger gun on a conventional hull. Big guns are cheaper than anti-tank missiles of equal firepower.

If this is for use on earth you can set your reactor output temp at ~300K. The atmosphere is an amazing heat sink. I could, or I could keep it more then 2k kelvins to cook enemy infantry at this point, its more like an infared death laser than a radiator... you could put some bronze mirroring to focus it on one area

IT'S THE FLIPPIN HG WELL'S CLASSIC NOVEL "WAR OF THE WORLDS" There's no need to be upset nobody understood your obscure reference The first literary work using Martian aliens as the main antagonists. It was turned into a radio play and several movies (and went on to popularize the idea of Martian invasions), so is hardly obscure. I've read the book (fighting heat-ray wielding Martians with field guns and lewis guns FTW) and watched the movie (the one from the 50's, there were several remakes AFAIK).

I remember doing calculations about their effective energy density (how much you can get out of them) the results were rather unsatisfactory, also I don't know how well you can pump your railgun with something that is effectively an Military-grade EMP.

Should be: energy density of high explosive * fraction of device that is explosive * efficiency Impedance matching and timing might be challenging... or maybe just weird? Attaching one to a railgun would be a weird interaction where compressing magnetic flux in one device exhausts it into the other.
