 She transferred to the 5th Battle Squadron and was used in experiments with flying off aircraft from May 1912 until 1913, employing a ramp built over her forecastle which had been transferred from the battleship "Hibernia".During these experiments, Commander Charles Rumney Samson—who had made the worlds first takeoff from a moving ship in May 1912 from "Hibernia" using a Short Improved S.27 biplane and the same ramp—repeated his feat by taking off in the same aeroplane from "London" on 4 July 1912 while "London" was underway.In 1913, "London" had her anti-torpedo nets removed.
