Would be good to know what other quests you currently have available to take a guess about which could be required for unlocking.

Some random guessing: Since it sorties to 1-4 and 1-6 you could start with quarterly 1-6 2BBV/AO or Monthly 1-4 to see if those recurring quests are locking it, if you haven't done those already. Besides that check if you still haven't done other quests that require the same ships and try doing them as well.
