About the plane.
The BS61 is a heavy twin - engine aircraft designed for a variety of tasks . The standard modification has proven itself well as an attack aircraft , since the aircraft turned out to live with the help of a two - beam scheme , an air - cooled engine and a rear turret with a 20 - millimeter cannon . During the war , it turned out that the BS61 was an excellent night interceptor . Modification BS61N (Night) has a radar in the nose, because of which it was necessary to enlarge the nose of the aircraft and add one crew member.

Postscript. I am trying to make standards for my planes , and I would like to ask , how do you like the size of this plane , did it turn out to be small ?
