 | | As in the case of all large British rockets, except for Blue Streak, it was powered by a mixture of kerosene and hydrogen peroxide – the same liquid propellant used by the German World War II Messerschmitt 262 interceptor. |
 | | Consisting in its first version of a single-stage, 10.2 meters high, 1.8 meters in diameter, and weighing 5.4 tons at takeoff, Black Knight was propelled by an Armstrong-Siddeley Gamma 201 engine equipped with four swiveling nozzles that developed 75,000 newtons (N) of thrust during a burn time of 140-145 seconds. |
 | | On Sep. 7, 1958, Black Knight 01 took off from Woomera and reached what was then a new record altitude of 564 km – an impressive achievement considering that the first Soviet and American satellites, Sputnik 1 and Explorer 1, had already been launched. |
