The Shipyard queue handles both ships and defenses. Resources are charged when an item is queued, and each entry stores its per-unit production time as calculated at that moment.
How does the shared queue work?
Fleet and defense use the same production queue on a planet. Hangar/Shipyard level 1+ and the unit’s requirements are needed. Costs, resources and limits are validated before adding.
When are resources paid?
The full queued cost is paid immediately. Later changes in stored resources do not invalidate an already accepted order.
How much is refunded on cancellation?
Cancellation returns 75% of the metal, crystal and deuterium actually paid: refund = paid cost × 0.75. A 2,000,000 / 1,000,000 / 400,000 order therefore returns 1,500,000 / 750,000 / 300,000.
What happens when the current item is cancelled?
The next entry is promoted and begins from the current moment; remaining queue timings are rebuilt. A later item can also be cancelled before it has already settled as completed.
How do missile and special-defense limits interact with the queue?
Queued missiles already count toward Missile Silo capacity. Limited special defenses count owned + queued + new units, with the current cap 1 + Bunker Officer level.
Can per-unit time change after queueing?
The entry stores its timePerUnit when added, so an existing job is not freely recalculated after every account change.
What determines production time?
For ships and defense the base relation is approximately hours = total cost / (2500 × (1 + Shipyard) × gameSpeed × 2^Nanofactory). The result is then multiplied by all active time-reduction factors. Constructor reduces building/shipyard time by 5% per level and Resort Officer by 2% per level; temporary build bonuses, construction development, avatar bonuses, gameplay modifiers and the active building-time event multiplier are also applied. Repeated percentage reductions are multiplicative rather than simple percentage subtraction.
The resulting timePerUnit is stored when the queue item is created. While the player is in vacation mode, the shipyard worker does not settle due units; after vacation, due work can be settled according to the preserved timestamps. A queue item whose end time has already passed cannot be cancelled until the game state is settled/refreshed.
