Oh you absolutely can change an engine at sea. Naval aircraft are very modular for good reason. Engines can be removed and tested (there's a whole massive test jig and setup on the fantail for it), and removed and replaced at sea. A whole wing replacement, I'm actually not sure but it wouldn't surprise me at all. You might not see a port for nine months or a year -- that's not an acceptable amount of time to just have a plane or multiple planes down waiting on parts that are available. There's no way to get them off the ship other than a crane pierside if they can't fly. The entire reason for the switch from the C-2 to the MV-22 for Carrier resupply was to be able to bring an F35 engine replacement aboard. https://www.youtube.com/watch?v=OeNCtMkaYRs https://www.youtube.com/watch?v=OeNCtMkaYRs https://www.youtube.com/watch?v=QHC4CqCy9RY https://www.youtube.com/watch?v=QHC4CqCy9RY
