BNS Tocantins (CA-1934)


Back to Other Ships List


Built as scouts for the battlefleet Brazil had bought from Great Britain, these two ships were also built in Southern Africa as typical British cruisers. The Brazilians ships mounted 9.2" guns in triple mounts. The Brazilian guns and turrets were built from new in Southern Africa. The guns built for these ships were the same 'Norwegian' 9.2" as fitted originally to the monitor / coast defence ships being built for Norway. (see HMSAS Rhinoceros) These were very long ranged guns and would give the ships an edge when undertaking their scouting duties. (see Navweaps)

With a secondary armament of 9 x 4" in single AA mounts, the twins that the Brazilians would have liked to mount on the ship were not available for two more years. Thought was given to upgrading these weapons as the various refits fell due. But the cost was always considered more than any advantage the change might make. Quad 2 pounder and Hispano-Suiza 20mm rounded out the light armament.

Early 1940 and both ships were overdue for their electronics refit at Simonstown. Until the Argentinian minelayers were neutralised, these ships would remain part of the Fast Response Force. The Battle of the Uruguayan Shelf ended the minelaying threat and both ships crossed the Atlantic to Simonstown.

The Royal Navy had made note of the long range guns aboard these ships and would request the ships join any task force that was liable to require land fire support.
