The Acre-class destroyers were a class of six destroyers built during World War II for the Brazilian Navy. None were completed before the end of the war. They are also referred to in some sources as the Amazonas class.
The ships were built in Brazil to a modified British design (but with some U.S. equipment) to replace six H-class destroyers (or Jurua class) ordered from Britain but purchased by Britain for use in the war. The ships took a long time to complete, being finished in 1949-1951
The ships received a refit in the early 1960s with new electronics and the no. 2 gun being replaced by a 40mm Bofors mounting. Two ships were decommissioned in 1964 and the remaining four in 1973/4.
