The first, proposed in 1958, was for a
Tupolev Tu-95 derivative carrying a long-range cruise-missile, to be based on the
Tsybin RS (S-30), Tupolev Samolyot 100 or Tupolev Samolyot 113 missiles. The combination was estimated to have a total range of approximately . Two years later the second iteration of '135' was envisioned as a supersonic interdiction bomber powered by a variety of engines in many configurations, including as a
nuclear-powered bomber. The design settled to a canard delta, similar to the
North American XB-70A Valkyrie, with paired
Kuznetsov NK-6 turbofan engine nacelles under each wing and a large single fin. Weapons would largely have been missiles, as designed, for maritime interdiction as well as long-range interdiction of enemy logistics. The design was constantly evolving and gave Tupolev valuable experience which would assist in the later design of the
Tupolev Tu-22M and
Tupolev Tu-160 bombers. == Specifications (estimated) ==
