[edit] Development
The Kadett was designed in 1933 to meet an official requirement for a basic trainer. It was a single-bay biplane of fabric-covered, metal construction with open cockpits, a staggered single-bay biplane wing, a strut-braced tail unit, and fixed landing gear with tailskid. The prototype was powered by a 104 kW (140 bhp) Argus As 8B inline engine.[1]
The first production model, the He 72A retained the As 8B engine in early batches, but later production aircraft had an As 8R of 112 kW (150 bhp). The He 72A was superseded by the He 72B, which was the major production version. This was powered by a 120 kW (160 bhp) Siemens-Halske Sh 14A engine. The He 72B was produced as the He 72B-1 landplane and He 72BW Seekadett (sea cadet) twin-float seaplane. The civil development was the He 72B-3 Edelkadett (noble cadet).[1]
[edit] Operational history
The Kadett entered service with National Socialist Flyers Corps before the formation of the Luftwaffe. Later it became a standard basic trainer with the Luftwaffe. Slovak forces used it in the attack role.[1]
