Heres a tough one. take one Nebula sensor model, 3 Novas and 2 Rhode Islands, on patrol and come accross a meeting of 2 dominion attack ships, a cruiser, 2 cardassian galors and a keldon, and 2 Breen frigates. I flew the Nova all times just to make it tougher, man what a underpower ship, died 2 out of 4 times, one of those times I accidently ran into another ship, but the battle was going badly anyways, the breen managed to disable 2 novas and the nedula, how they managed to hit the novas is a mystery to me, but I highly doubt I was coming out alive in that fight either way. Last battle I took out the rhode islands and replaced it with them with novas so now there were 5 novas including me, the nebula some how survived with little damage, I barely survived along with 2 other novas which were badly damaged too
