ARA Buenos Aires (BB-1935)
Return to Argentine Ships
1930 and Argentina was in a much better position financially than most.
Argentina was still very much cash and carry, so it did not rely on the paper
money used in Europe and the US. Argentina was still not quite ready to build
their own capital ships, it would be another 4 years before they laid down their
first. The United States was more than ready to build a pair of small
battleships for some much needed foreign exchange. Back to the Fore River Navy
Yard, and a design for an 8x 14" battleship. This size was specifically chosen
so as not to give the other South American nations a reason to start a new
'dreadnought' race.
At 30,000 tons standard displacement, they were not huge ships, but were better,
ton for ton, than anything else in South America. The single 5" were the only
ones in the fleet and were replaced by the twin 88mm turrets that were being
produced locally from 1936 onwards. This gave the two ships an exceptional heavy
AA barage armament. The high velocity weapon also fired as far as the US 5", so
was also very good at keeping destroyers at bay and outside torpedo range
(except for those pesky Japanese). By 1939 both ships had been rebuilt with
German guns and gunnery controllers.

The US 28mm quad mountings were replaced with German 20mm and 37mm weapons.
The US twin 14 was a better guns than the German 12" and proved excellent in
service.
