V-2 rocket offensive began on 8 September 1944, when "Lehr- und Versuchsbatterie No. 444" () launched a single rocket guided by a radio beam directed at Paris. Wreckage of combat V-2s occasionally contained the transponder for velocity and fuel cutoff. The painting of the operational V-2s was mostly a ragged-edged pattern with several variations, but at the end of the war a plain olive green rocket also appeared. During tests, the rocket was painted in a characteristic black-and-white chessboard pattern, which aided in determining if the rocket was spinning around its longitudinal axis. The original German designation of the rocket was "V2",
Rocket launcher many cases, rocket pods are streamlined to reduce aerodynamic drag. The first pods were developed immediately after World War II, as an improvement over the previous arrangement of firing rockets from rails, racks or tubes fixed under the wings of aircraft. Early examples of pod-launched rockets were the US Folding-Fin Aerial Rocket and the French SNEB. Larger-scale devices which serve to launch rockets include the multiple rocket launcher, a type of unguided rocket artillery system. Rocket launcher A rocket launcher is a device that launches an unguided, rocket-propelled projectile, although the term is often used in reference to mechanisms that
