abstract | - The first production model of the B6N1 with only around 133 examples produced. The B6N1 had a Nakajima NK7A Mamoru engine that was capable of propelling it at speeds of up 480 kilometers per hour. The armament of the B6N consisted of a single 7.7mm machine gun firing from the gunner position and a secondary 7.7mm machine gun firing through a ventral position. Early examples though had a 7.7mm machine gun mounted in a forward firing mount in the port wing of the aircraft. However, the B6N had a crew of three crew members, with the third crew member being a navigator/bombardier. The total length of the B6N was around 10.8 meters with a total weight of around 3,010 kilograms. The aircraft also had a maximum range of around 1,700 kilometers with a service ceiling of about 9,000 meters. The reliability of the B6N in the field was excellent with the aircraft's engine power being much improved from its predecessor, the B5N.
