Project history: After 4.9.1939 Great Britain requisitioned 6 J class destroyers (Jurua, Javary, Jutahy, Juruena, Jaguaribe, Japarua),
built under Brazilian order, the decision on building instead of their equivalent series on domestic
shipyards was accepted. Six Acre class destroyers were laid down in 1940, however because of weak technical base and a lack of experience of
builders, building was delayed, and ships were completed late after war.
Initial design practically repeated requisitioned ships which had in a basis
British H class ships, however reorientation of Brazilian shipbuilding programme from
British to American help has affected on their appearance and equipment. Finally destroyers
preserved a few common features with their British prototype, and outwardly began to resemble
American Craven class, in particular, instead of two funnels there was one.
Armament have been unified with M class ships and included 4 single Mk12 127mm/38
guns (closed mount for No1 gun and opened for remaining), twin 40mm/56 Bofors
MGs, 4 single 20mm/70 Oerlikons and 2 triple 533mm TTs, placing
aside amidships. All armaments, radars and
fire control systems were US-built. Acre and Ajuricaba were equipped
by General Electric 34600hp turbines and made 33.5kts
and had triple TT mounts. Remaining ships of class had Westinghouse 45000hp
engines, made up to 36kts and had quadruple TTs. Besides, Acre did not
had 40mm MGs.
Modernizations: 1954-1955, all were armed with: 3 x 1 - 127/38 (1 Mk 30, 2 Mk 21), 2 x 2 - 40/60 Mk 1, 4 x 1 - 20/70 Mk 4, 2 x 3 - 533 TT, 8 DCT, 2 DCR, SPS-4, SPS-10 radars, QCR-1 sonar
Naval service: No significant events.
