1-20 either 1-1 grind if you want something really boring, otherwise use them as tanks at 3-2-A, once they hit 20 they'll be relatively alright to start cruising Orel as a fleet (3+ subs) but expect damage pretty often, the resource nodes can usually pay for the deployment costs and ship drops can cover repairs.

PvP is obviously the best, but that's not always accessible, 2-4-A and 5-4-A are alternatives to 3-2-A depending on how far you've progressed through the maps.
