Myasishchev Mya-4 Bison B/C
The original version of the M-4, known as the Bison-A, was the first operational four-jet bomber produced by the Soviet Union and was intended to carry only free-fall nuclear and conventional weapons.
However, the Bison proved a disappointment as a bomber and the turboprop Tu-95 Bear soon took on this role. Many of the original bomber versions of the Bison-A were converted to a maritime reconnaissance role as either Bison-B or Bison-C.
Both types were equipped with a large radar, cameras and SIGINT equipment
