The sign which accompanied the V-2 when it was in the Air Power Gallery. It
reads
V-2 Rocket Engine
This is the rocket engine which powered the remarkable V-2 "Vengeance Weapon" developed by Germany
during WW II and fired against London, Antwerp, Liege, Brussels, Paris, and
Luxembourg. Using liquid oxygen and alcohol as propellants, it produced a
thrust of 56,000 lbs., giving the V-2 a maximum range of 220 miles, a ceiling
of 55 miles, and a velocity of 3,500 mph. Approximately 6,500 V-2s were
manufactured during 1944-45.
