Her completion was delayed by labour troubles and the possibility that she might be repurchased by Chile for reconversion into a battleship, as well as the need for comparative trials to determine the optimum layout for aircraft carriers.

As Almirante Latorre was almost complete, she was purchased for the Royal Navy, entering service as in 1915. Almirante Cochrane was virtually complete up to the forecastle, although her side armour had not yet been installed when war broke out. No work was carried out during the war until the British decided to complete her as an aircraft carrier for the Royal Navy. She was therefore purchased from Chile on 28 February 1918 to be converted into the carrier HMS Eagle. She was the fourteenth ship of the Royal Navy to bear that name.

The bridge was mounted on top of this bracing which left a clear height of 20 feet (6.1 m) for the aircraft on the flight deck. There was a 68 feet (20.7 m) wide space between the islands where the aircraft were to be assembled before taking off.

Based on trials with , in which pilots were found generally to turn to port when recovering from an aborted landing, the design was revised to eliminate the port island in April 1918. The starboard island was lengthened to 130 feet (39.6 m) and its width was reduced to 15 feet (4.6 m) to minimise air turbulence. The island contained the bridge, both funnels and the tripod mast that carried the fire-control directors for the armament. At the request of Admiral David Beatty

The existing 1.5 inches (4 cm) upper deck became the floor of the hangar deck and a new superstructure was built above it. The flight deck was 1 inches (2.5 cm) thick and served as the uppermost strength deck, or main supporting deck, of the ship. When the war ended in November 1918, the ship was about nine months from completion.

The £2.5 million cost to do so would have been higher than the £1.5 million offered by the Chileans and the Admiralty decided to retain the ship. The Royal Navy needed to carry out flying trials with a carrier fitted with an island, and the Admiralty approved her use for said trials shortly afterwards on 11 November. Armstrong Whitworth plated over the openings for the undelivered elevators on the flight deck (which had been cancelled when they could not meet the specifications), finished the rear funnel, removed the torpedo tubes, and plated over the forward funnel uptakes before she sailed to the Royal dockyard at Portsmouth

 used previously on the small aircraft carrier . They were not intended to stop landing aircraft—the landing speeds of the time were low enough that this was unnecessary given a good headwind—but rather to prevent aircraft from veering off to one side and potentially falling off the flight deck. Initially, the arresting gear was about 170 feet (51.8 m) long and was installed too far forward. Over the course of the trials it was moved further to the rear and lengthened to a total of 320 feet (97.5 m).

The ship's designed fuel capacity was 3000 LT, but this was increased to 3750 LT when she was bulged. However, 500 LT of this amount was required to act as ballast to offset the weight of the island and its equipment.

Eagle had an overall length of 667 in 6 in (203.45 m), a beam of 115 feet (35.1 m), and a draught of 26 in 8 in (8.13 m) at deep load. She displaced 21850 LT at standard load. Each of the ship's four sets of Brown-Curtis geared steam turbine

A single High Angle Control System (HACS) director was fitted on the aft end of the control top on the tripod mast. The crew, now numbering 753 sailors and 253 airmen, benefited from improved accommodation. The refit was completed on 28 November 1932, but personnel shortages prevented her from working up until April 1933.

Following the refit, Eagle was sent to the Far East, serving on the China Station throughout 1934, with her aircraft being deployed against pirate ships and their bases. The tropical heat caused problems in cooling the bomb magazines, and the food storage rooms and the ventilation proved to be barely satisfactory. Another quadruple .50 machine gun mount was added forward of the 2-pounder gun on the flight deck and the original mounting was shifted over to the port side.
