Talk:Orbital defense platform

Im pretty sure that there we 20 ODPs defending Reach edit: Not nesscessarily Earth, as there were ODPs over Reach--UNSC AI 12:02, 30 May 2007 (UTC)

Your correct page 283 in Fall of Reach states that "there were 20 super MAC guns in orbit" I made the proper change

something
after reach you'd think they would reaseach a way to put generators on the guns,so they're more of a threat and are "easier" to defend,and i'm guessing the Earth is a WHOLE lot bigger then Reach cause if 20 was in orbit around Reach and 300 around Earth Voy101

Real Life Inspiration
Does anyone else think that these platforms seem a bit like what Ronald Reagan imagined for the Stratigic Defense Initiative (SDI or "Star Wars") program? Flag-Waving American Patriot 19:02, 21 November 2007 (UTC)

Well, if one takes point four tenths the speed of light as meaning .4c, then the energy requirement of an MAC is enormous. Using E = 1/2 MV^2, with a v = 2.99E7 and an M of 600 tons (converted to Kg of course), we get an energy usage of over 5,306 gigatons TNT! (A typical nuclear bomb is about 20 megatons).

It's not unreasonable to assume that numerous power plants and generators would be required to support the weapon, and I'm imagine that trying to generate all that power on a mobile station would be no easy feat.

Tense
Why is this written in past tense? Aren't there still MAC cannons in orbit around Earth even after the events of Halo 3? And even if most were destroyed, one would think that rebuilding them would be a top defense priority for the UNSC government.
