The Fleet

This page reads copies of craft.json, craft.sections.json, components.json, sections.json, and craft.mission.json — the same files the game boots from — and derives each craft's engineering readout the way the in-game panel does: nothing below is hand-written. Mass, thrust, Isp, and Δv all fall out of the build. (Δv here is the ideal rocket-equation figure for the ship alone; the mission compiler additionally accounts for staging, payload injection, and drag.)
