Design

The Tu-123 was a long-range, high-altitude supersonic strategic unmanned reconnaissance aircraft, in a form reminiscent of a big dart, conceptually somewhat similar to the United States' D-21. It carried both

History

Development

The Tu-123 was a development of the proposed Tupolev Tu-121 supersonic nuclear-armed cruise missile program. After the cancellation of that project in favor of

s, the design was modified for a high-altitude reconnaissance role. The project was officially launched on 16 August 1960, under the designation “DBR-1” with the Tupolev Design Bureau designation of “I123K” (later changed to “Tu-123”). Factory testing was completed in September 1961 and flight tests by December 1963. The new UAV entered active service on 23 May 1964. Mass production was at

intelligence units stationed in the western border military districts until 1979. It had (theoretically) the range to cover all of Central and Western Europe, and performed well in training exercises. However, the expense of operating an expendable system was unsatisfactory. This led to the development of the Tu-139 Yastreb 2, a reusable version which could land on unprepared airstrips. It was never put into production. The Tu-123 was gradually removed from service, and replaced by the
