HMS Glorious was a British Courageous Class aircraft carrier of 18600 tons displacement and sister ship to HMS Courageous. Like HMS Courageous, HMS Glorious was completed in 1917 as a fast cruiser for use in the Great War in the Baltic, but by the 1920s with Britain wanting to increase her aircraft carrier strength she was converted to an aircraft carrier, as was HMS Courageous. HMS Glorious was powered by eighteen Yarrow boilers providing a top speed of 31 knots. She was armed with sixteen 4.7 inch guns, four 3-pounder guns and fifty smaller guns and carried a crew of 1100 and six aircraft comprising two Flycatcher fighter aircraft, two Fairey III reconnaissance and two Darttorpedo aircraft.
