Physics/HALO UNSC Frigate MAC


Hi! In HALO UNSC frigates have 183 meter long magnetic accelerator cannons that are coilguns that accelerate a 600 ton depleted uranium projectile to 30km/s impacting with 270000000000000 joules which is 64,5 kilotons. This gun takes around a minute to charge.The frigates of UNSC have a mass of 4000 tons which is a big mistake done by game designers because then they are 1/4th of the density of air... But fans have measured a mass of 1 million metric tons. So let's go with that. How feasible does this weapon sound to you and are there any specific problems in it and would the 600 ton deplete uranium projectile even have chances of surviving the atmospheric entry or would it burn up? Would this weapon work?

Fans "measured" a mass of 1 million metric tons?  How did they "measure" something that doesn't exist, exactly?  This weapon is ridiculous, of course, as is the mass of 4000 tons.  The projectile would "burn" when it hit atmosphere, but would the momentum of the resulting molten/fluid material retain massive momentum?  Yes it would.

I can answer most basic physics questions, physics questions about science fiction and everyday observations of physics, etc. I'm also usually good for science fair advice (I'm the regional science fair director). I do not answer homework problems. I will occasionally point out where a homework solution went wrong, though. I'm usually good at explaining odd observations that seem counterintuitive, energy science, nuclear physics, nuclear astrophysics, and alternative theories of physics are my specialties.


I was a physics professor at the University of Texas of the Permian Basin, research in nuclear technology and nuclear astrophysics. My travelling science show saw over 20,000 students of all ages. I taught physics, nuclear chemistry, radiation safety, vacuum technology, and answer tons of questions as I tour schools encouraging students to consider careers in science. I moved on to a non-academic job with more research just recently.

Ph. D. from Duke University in physics, research in nuclear astrophysics reactions, gamma-ray astronomy technology, and advanced nuclear reactors.
