Do you need the specialists after you've already created the item?

[Ewwokk]

Electrospinning, Radar and so on specialists. I got them, created the items they are required for, but do I need them after the item has been created? Because they're all A rankings and I could easily replace them with S or S+'s but if I dismiss them will I lose access to the items?

Dismiss if you don't need them for future upgrades, you keep the items that are ALREADY developed.

Yeah, you won't lose access to the items. Dismiss them at will.

You may want to double-check that you don't have any more use for them, though. You probably don't want to go through the acquirement process again.

And if you find you DO need them to develop an item (futures game updates may require a specialists skill), simply check the mission screen to see which mission the specialist is in and then return to the mission and recruit them again.
