 The planned Hs 130B was almost the same as the Hs 130A, but with a bomb bay in place of the camera bay, but was never built.The Hs 130C was built as a competitor for the "Bomber B" project, and was very different from the Hs 130A, featuring a shorter wing span, remotely controlled defensive armament, a more extensively glazed (but still pressurized) cabin and up to 4,000 kg (8,800 lb) of bombs.Three prototypes, V1, V2, and V3 were built, with V1 and V2 were powered by BMW 801 radials, and V3, featuring full armament, was powered with a pair of Germany's largest displacement — at some 44.5 litres apiece — inline inverted V-12s, the Daimler-Benz DB 603A engine.
