The Heinkel HE 3 was a sports aircraft built in Germany in the early 1920s. It was a conventional, low-wing monoplane with seating for three people in two tandem cockpits. The wing was a cantilever design, an unusual and advanced feature for the day. The fixed undercarriage was designed to be quickly changed from wheeled tailskid type to twin pontoons for operation as a seaplane. A HE 3 won first prize in its class at the 1923 aero meet at Gothenburg, and was subsequently selected as a trainer by the Swedish Navy, which bought two examples. In Swedish service, the aircraft gained the nickname Paddan ("Toad").

L'Heinkel HE 3 era un velivolo sportivo costruito in Germania nei primi anni 1920. Era un monoplano convenzionale ad ala bassa con posti a sedere per tre persone. L'ala era dotata di montanti invece che tiranti (una caratteristica insolita e avanzata per i tempi)[1]. Il carrello fisso venne progettato per essere rapidamente cambiata da pattino a ruote a scarpone per il funzionamento da idrovolante. L'HE 3 vinse il primo premio nella sua categoria nel 1923 nella manifestazione aerea a Göteborg e venne successivamente selezionato come aereo da addestramento dalla marina svedese che ne acquistò due esemplari. In svedese l'aereo venne soprannominato di Paddan ("Rospo").
