I have few times, dont sit still/go slow! as.. third game in one, dropped to half speed as a destroyer was about to turn corner on island (was about to shoot torps on him) and got hit by Bb full on from max range.. instant kill and was only tier 3 and first minute of the game.
They have smoke and heal, ap only shells and decent torps/fire/speed/weak armour from what know about them.
