Heinkel Jet Aircraft

On 27 August 1939 the Heinkel He 178 became the first aircraft to take to the skies powered entirely by a turbojet engine, twenty months before the first flight by a British jet aircraft.
The Heinkel He 162 Spatz, better known as the Volksjäger, or People's Fighter, was a single-engined jet fighter went from a basic design to its maiden flight in three months at the end of 1944, but that had barely entered service before the end of the Second World War.
The Heinkel He 280 was the first jet powered fighter aircraft to take to the skies, although it never entered mass production
