MAC Round Impact

Kinetic energy of a Magnetic Accelerator Cannon.

📜 The Origins

A 600-ton slug at 40% of the speed of light simply doesn't care about your shields. Calculate the raw destructive power of the UNSC's big stick.

Mass Driver Physics

The UNSC's primary weapon is the Magnetic Accelerator Cannon (MAC). It's a giant railgun running the length of the ship.

The Stats (Super-MAC)

  • Projectile: 3,000-ton Ferric-Tungsten slug.
  • Speed: 4% the speed of light (12,000 km/s).
  • Kinetic Energy: $K = rac{1}{2}mv^2$.
  • This impacts with the force of roughly 50 Gigatons of TNT.
  • For context, the Tsar Bomba (largest nuke ever) was 0.05 Gigatons.

"Sir Isaac Newton"

As the Drill Sergeant says: *"This recruit, is a 20-kilo ferrous slug. Feel the weight! Every five seconds, the main gun of an Everest-class Dreadnought accelerates one to 1.3 percent of light speed. It impacts with the force of a 38-kiloton bomb. That is three times the yield of the city destroyer that fell on Kowak ... That means: Sir Isaac Newton is the deadliest son-of-a-b***h in space!"*

Pro tips
01Sir Isaac Newton is the deadliest son-of-a-bitch in space.
02Don't eyeball it.
03Firing 'Super MACs' requires ground generators.

The Fine Print (FAQ)

Can Covenant shields stop it?
Ship shields? Yes, barely. But a Super-MAC (orbital platform) punches right through a capital ship and the ship behind it.
Why not missiles?
Missiles (Archer pods) are used to overwhelm point defense. The MAC is the knockout punch.
Is this possible today?
The Navy has railguns, but powering them is the issue. We need fusion reactors to generate that kind of magnetic field.
