Myasishchev 3MS.2 “BISON-B”

The Myasishchev 3MS.2 “Bison-B” aerial refueling tanker aircraft is a derivative of the Myasishchev M-4 “Bison-A” strategic bomber. A few units were manufactured by mounting old Mikulin RD-3M-500a engines in new 3-MS airframes, but most of aircrafts were conversions of Mya 3-M bombers. It was intended to mount the new Dobrynin VD-7 engines on the Mya 3-M aircrafts, but due to the lack of reliability of these engines, they were never completed with this layout. Between 1970 and 1980 the Mya 3-MS and Mya 3-MD bombers that were in service became tankers and served until 1994. The “Bison-B” tankers carried up to 40,000 liters of jet fuel that was transferred to the aircrafts through a probe and a hose installed in the bomb bay at a rate of 2,250 l / min.
