Modifications
1942: Machine guns replaced with 6 20mm Oerlikon AA guns. Fire control radar added, most likely FC at first. Four depth charge throwers added and depth charge loadout increased to 44.
1943: 1x2 40mm Bofors AA guns added.


The Bagleys were ordered in 1935. They were very similar to the Gridleys but were completed in Navy yards in 1937.  The commercial shipyards responsible for the Gridleys apparently cut many corners in construction which the Navy did not, with the result that the Bagleys were both structurally stronger and more stable. This allowed them to receive more light antiaircraft armament as the war progressed. However, they also reverted to the slightly less powerful machinery used in the Mahans, making them somewhat slower.
