In 1933, Udet joined the Nazi Party and became involved in the early development of the Luftwaffe, where he was appointed director of research and development. Influential in the adoption of dive bombing techniques as well as the Stuka dive bomber, by 1939 Udet had risen to the post of Director-General of Equipment for the Luftwaffe. The stress of the position and his distaste for administrative duties led to Udet developing alcoholism.
