, but its original design was changed in January 1944.
The second version of the aircraft retained the two machine guns, but its front section was a detachable explosive nose with stabilizing fins filled with 400 kg of explosives. The pilot sat in the cockpit near the tail which was in the back section. The plane proper had a wingspan of 5.7 m and a length of 5.3 m. Including the ejectable nose its length would be 7 m.
The plane would have been released from a mother plane upon reaching combat altitude. Then it would ignite its single
