The Nakajima Ki-49 Donryu, meaning Storm Dragon and known to the Allies as Helen, was a twin-engine heavy bomber built by Nakajima for the Imperial Japanese Army Air Service as the Army Type 100 Heavy Bomber. A 1938 specification to replace the Mitsubishi Ki-21 asked for enough speed and defensive armament to bomb by day without fighter escort, so the Ki-49 carried a dorsal cannon, a tail turret and armour but could lift only 1,000 kg of bombs in its first version. It flew in August 1939, entered service two years later and served in China, New Guinea and raids on Australia. Production ended in December 1944 after 819 aircraft, and most survivors were expended in kamikaze attacks.
