Tsybin RSR
The Tsybin RSR (Reactivnyy Strategicheskiy Razvedchik, Cyrillic Реактивный Стратегический Разведчик, Russian for "jet strategic reconnaissance") was a Soviet design for an advanced, long-range, Mach 3 strategic reconnaissance aircraft. == Development and design == In 1954, the design bureau headed by Pavel Tsybin started development of a ramjet-powered supersonic strategic bomber, the RS. This design proved impracticable, and a smaller derivative, the 2RS was proposed, which would achieve intercontinental range by being air-launched from a modified Tupolev Tu-95 bomber.
