Alarmed at the Brazilian move , Argentina and Chile quickly nullified their 1902 pact and sought dreadnoughts of their own . Argentina 's orders , after a drawn-out bidding process , went to an American company , Fore River Shipbuilding Company , while Chile 's orders , delayed by the 1906 Valparaíso earthquake , went to Armstrong . Since Brazil 's relations with Argentina were warming and the country 's economic boom was losing steam , the government negotiated with Armstrong to remove the third dreadnought from the contract , but without success . They borrowed the necessary money , and Armstrong laid down '' Rio de Janeiro '' s keel in March 1910
