Slightly larger "A"
class destroyers, except that destroyer sweeps were replaced by
asdic, DC racks and throwers.
Brilliant had her tubes replaced in the war, the after set being removed in this and most "A"-"I" class pre-war for a 3" 12pdr AA, and "Y" gun was removed to fit more DC's and their throwers.
Bulldog had a "hedgehog" in place of "A" 4.7" gun, and a 2 pdr. "bowchaser" gun to deal with E-boats. Boreas was the only member to retain the director tower, others using radar ( SW type 271 ) or local control.
