Expedition Efficiency Calculator

Expeditions (遠征) are how you pull in fuel, ammo, steel, and bauxite without sortieing — but they're not equally worth a fleet slot. Enter any expedition's time and rewards to get a bauxite-weighted efficiency score, so you can tell at a glance which one is actually worth running.

Efficiency Calculator

Score/hr = (Fuel + Ammo + Steel + Bauxite×3) ÷ hours. Sort by whichever resource you're short on, or by overall Score to see the best all-round use of a fleet slot.

NameMinFuelAmmoSteelBauxiteScore/hr
Why bauxite counts 3×. Fuel, ammo, and steel all regenerate on their own over time at similar rates; bauxite regenerates far slower, so a bauxite reward is worth more than the same number of any other resource. This 1:1:1:3 weighting (sometimes called a "GSweight") is the community-standard way to compare expeditions that give completely different resource mixes on an apples-to-apples basis.
