For what it's worth, Zero-K requires ALL bombers to reload at air staging after a single pass but all bombs are extremely powerful, and it's colossally infuriating because if your air player misses the radar signature heading towards the front line, too bad! The bomb is dropped and the bomber has already had its order stopped and is flying back over enemy AA to be refueled in the middle of the enemy base. Hope you catch it next time! Great idea in practice to stop bomber camping, I personally love the idea of having to reload t1 bombers after 5 passes, but horrendous execution in existing games.
EDIT: Also an important note, the air factories in Zero-K come with a single refuel/reload point each, meaning you don't need dedicated air staging early game.
