After the forward flight deck was widened in 1936, an additional eight wires were added there to allow aircraft to land over the bow if the landing area at the stern was damaged.[12] The ship was built with a 155-foot (47.2 m), flywheel-powered, F Mk II aircraft catapult, also designed by Norden, on the starboard side of the bow.[6][10] This catapult was strong enough to launch a 10,000-pound (4,500 kg) aircraft at a speed of 48 knots (89 km/h; 55 mph).
