The V-2's liquid oxygen and alcohol propellants produced a thrust of 56,000 pounds, giving the rocket a maximum range of 220 miles, a ceiling of 50-60 miles and a speed of 3,400 mph. Germany made about 6,000 V-2s during 1944-1945 and launched more than 2,600 against London, Antwerp, Liege, Brussels, Paris and Luxembourg.
