Destroyer: One of the largest military spacecraft in common use, destroyers use an antimatter drive holding 150 tons of antimatter in a 2,000-ton magneticcontainment vessel. This antimatter can also be used to provide the spacecraft’s missiles with anti-matter for devastatingly powerful anti-matter warheads. This spacecraft is also armed with railguns, nuclear and high explosive missiles, and point defense lasers.
150 tons = 150,000 kilograms 150,000 kilograms of antimatter = 6,444 gigatons - almost twice the amount of energy that hits the Earth from the sun in 24 hours. One Destroyer uses up 150,000 months [12,500 years] worth of antimatter production from a single factory. To make enough antimatter in one year to power a single Destroyer would require 12,500 factories. The US Navy has 57 destroyers in service - just using this as a comparison. To power an equivalent number in Eclipse Phase with a year's worth of antimatter production, you would need 712,500 factories. Now, going back to the quote from Sunward: Mercury’s proximity to the sun, and the excess amounts of energy this provides, makes the planet an ideal place for energy-intensive processes: particularly antimatter production. As noted in the text, several antimatter factories exist on or in orbit above Mercury. Each consists of multiple particle accelerators (for slamming atoms together) and enormous solar arrays for collecting energy. These factories produce around a kilo of antimatter each month.
Several, in my mind, does not mean "seven hundred thousand factories". I think the numbers here are really really out of whack. We haven't even begun to get into the rest of the solar system putting antimatter to use. What about spacecraft larger than Destroyers? How do the Jovians go about supplying their apparently massive fleet of warships with so much antimatter, especially when they're so hostile with basically everyone else?
