The He 111D was a short-lived variant of the He 111, powered by two 1,050hp Daimler-Benz DB 600Ga engines. These more powerful engines pushed the top speed of the He 111D up to 254 mph, but they would be the new model's downfall. A shortage of the engines meant that only twenty He 111Ds were built before production switched to the Junkers Jumo powered He 111E.
Those twenty aircraft were split into ten D-1s and ten D-2s, the only difference being in the radio equipment installed. They were used as flying command posts, with a crew of eight, including two dedicated radio operators. All twenty aircraft were complete by the end of 1937.
