This is the list of the ship mission codes from the T5.10 book (book 2, p. 68), but organized differently. The purpose of this is to take another attempt to reconcile the wiki Ship Classification (and Starship-Nav-Bar-Two-2019CE) with the T5.10 mission codes. This is a request to make sure the T5.10 codes are propagated forward.

The T5 mission taxonomy is included where it clarifies the mission code.
