MMN, A.A.Arhangelsky
|
The MMN was an improved version of the SB, with a new wing. The fuselage nose and engine nacelles were cleaned up. Armament was decreased to 3 machineguns to save weight, but this was not appreciated by state acceptance commetee.
It remained a prototype, and continued development produced the Ar-2.
