In expedition menu, under event tab (which is red in color icon, below right), there will be a new expedition (no.175) with D rank difficulty, send 6 of any ships with Flagships above level 6

Wait 15 minutes, make sure you already activated the quest, then E-3 will be unlocked after you clear the quest
