How to equip aircraft parts in the Ace Combat 8 campaign

Open parts from mission preparation

1. Select the campaign mission you intend to fly.
2. Proceed to the preparation stage where you can set up your aircraft and teammates.
3. Look for the menu entry for changing aircraft parts.
4. Open it and choose from the parts you own. Review the selected effects before launching.

In the source thread, 8ightybytes gives this path in #1–2 and the original poster confirms it resolved their confusion in #3. The post does not document an exact keyboard shortcut or every platform’s screen labels, so use the visible menu entry.

Choose parts for the failure you are solving

Before buying or rearranging parts, name the problem: running out of missiles, struggling to turn onto a target, or spending too long killing a priority enemy. Then compare the available part descriptions against that problem. This is our preparation checklist, not a numerical optimization model.

For a concrete mission example, the Mission 8 clear report uses extra missile payload, while Mission 28 players report weapon-focused setups. Those reports should not be converted into a universal best-parts list.

Confirm that the change is on the intended aircraft

Recheck the mission-ready loadout after leaving the parts screen. If you switch aircraft afterward, confirm the displayed selection again. Save a screenshot of the final configuration when comparing attempts; a purchased part and an equipped part are different things.

This path concerns the campaign player aircraft. It does not establish that your wingmen inherit player parts. See post-campaign wingman aircraft and loadout limits for that separate question. Online aircraft upgrades also have their own progression.
