a two-level hangar was built under the flight deck, in height per level. the lower hangar was long by wide and the upper was . each hangar could be sectioned off by electrically operated steel shutters on rollers. her boilers were ducted down the side of the ship to exhaust either out of gratings at the rear of the flight deck or, when landing operations were in progress, out of the side of the lower hangar at the rear of the ship. this solution proved to be very unsatisfactory as it consumed valuable space, made parts of the lower hangar unbearable and interfered with landing operations to a greater or lesser degree. her original flying-off deck remained in place for use by small aircraft like fighters which improved launch and recovery cycle flexibility allowing the ship to simultaneously land aircraft on the main flight deck while fighters were taking off on the lower deck or to speedily fly off her aircraft from both decks. doors at the forward end of the upper hangar opened onto the lower flying deck. like "argus", "furious" was flush-decked and lacked an island superstructure to minimise any turbulence over the flight deck; instead she had a navigating position at the leading edge of the flight deck, starboard, and was provided with a retractable charthouse forward, on the flight deck centreline. the ship could normally carry about 36 aircraft.
