After "Repulse" completed her 1926 refit, she remained in commission, aside from a brief refit from July–September 1927, with the Battlecruiser Squadron of the Atlantic Fleet until she was paid off in June 1932 prior to beginning her reconstruction in April 1933. Most of the existing layers of high-tensile steel that constituted the ship's horizontal armour were replaced by non-cemented armour plates in thickness and the torpedo control tower was removed from the aft superstructure. A fixed catapult replaced the midships 4-inch triple mount and a hangar was built on each side of the rear funnel to house two of the ship's Fairey III aircraft. One additional aircraft could be carried on the deck and another on the catapult itself.
