Partly a mission concern - partly a shiplist concern here:
OK, the Suprise Reversed is a pain that I'd forgotten...
As an ISC DD the largest ship drawn was a K-C5!!!, by the time I destroyed it, all the other ships had powered up - undoable without a wing.
As a Klingon F5C the largest ship drawn was a Rom Sparrowhawk-A (seems like a bit of a difference...)
(I changed sides for balance, hope no one minds...)
