High masts placed recovery beacons where returning aircraft could see them from farther away. The carriers could also dispense illuminated floats to lay out a path toward the stern, resembling a line of runway lights. These fittings supported long-range night strikes and the recovery of aircraft afterward. The Royal Navy accepted compromises from the tall masts and other fittings because night operations were central to its carrier doctrine.
