Project history: In 1938 Brazil has ordered in Britain 6 destroyers of class as RN "Í". Important difference from a prototype was other, unique, main gun fire control system consisting of combined "director-range finder". In connection with the Second World War beginning all were bought up by British government 4.9.1939 and received new names.
Former Brazilian "Í" were finished building in the big haste, practically without obligatory in that case correction of the design to requirements of the British navy (not tested control system of fire, "export" torpedoes, etc.). Strengthening of anti-submarine armament at the expense of removing of aft 120mm gun on "Y" position and the minesweeping equipment became unique change. Reason of preference of ASW equipment instead of artillery is covered both in unavailability of a part of original armament, and in doubtful advantages of a new fire control system that strong decreased value of new destroyers as gunships. Besides, because of haste part of destroyers has become operational with incomplete fire control system: Havant, Hesperus, Havelock and Highlander participated in the first battle collisions, with only a rangefinder and Hesperus had no TTs till mid-1940. Only last two ships entered service fully completed.
