After the end of the war in Europe, Chile began to seek additional ships to bolster its fleet, and the United Kingdom eagerly offered many of its surplus warships. This action worried the nations of South America, who feared that a Chilean attempt to regain the title of "the first naval power in South America" would destabilize the region and start another naval arms race. Chile asked for Almirante Cochrane in addition to Canada, but would not purchase the ship unless she was reconstructed into the original battleship configuration. The British halted work on the incomplete ship while seriously considering the offer in October 1919. But because of the increased cost of reconverting her—£2.5 million, compared to a potential profit of £1.5 million from selling her—and a desire to test the aircraft carrier concept and especially the viability of island superstructures, the British kept and completed the ship, as .

In April 1920, Chile only bought Canada and four destroyers, all of which had been ordered by Chile prior to the war's outbreak and requisitioned by the British for the war. Planned replacements for Almirante Cochrane included the two remaining s, but a leak to the press of the secret negotiations to acquire them caused an uproar. The most visible dissension came from a block of officers in the navy who publicly opposed any possible purchase and instead promoted a "New Navy" which would acquire submarines and airplanes. They argued that these weapons would cost less and give the country, and its lengthy coastline, better protection from external threats. The ships were not bought for reasons of cost, but neither were the airplanes its supporters had been hoping for.

Almirante Cochrane/Eagle in British service

Eagle was used for trials throughout 1920. As the concept of aircraft carriers was still very new, the lessons learned were incorporated in a 1921–23 refit. Her official sea trials were conducted in September 1923, and she was commissioned on 26 February 1924. The new ship was sent to the Mediterranean Fleet
