Bachem Werke GmbH was founded on February 10, 1942, by Diplomeur Ingenieur Erich Bachem, formerly the Technischer Direktor of Fieseler Flugzeugbau. Bachem manufactured spare parts for piston-engine fighters and other aircraft equipment before their moment of fame with the Natter project.
From 1944 this company, with a design team led by Dipl Ing Erich Bachem (formerly technical director of Fieseler- Werke), began development of the Ba 349 Natter, a vertically launched rocket-powered piloted missile that was intended to attack Allied bomber concentrations. Following launch, the pilot would attack the enemy aircraft with unguided rockets, and complete his sortie with a parachute extraction from the expendable aircraft and descent to the ground. The rear fuselage of the Natter and its Walter rocket motor was also recovered by parachute. So far as is known only one piloted launch was made, in February 1945, when test pilot Lothar Siebert was killed. The Allied advance prevented completion of the project, and none of these aircraft was used operationally.
