The Tupolev Tu-123 Jastreb (project name DBR-1; Russian Ястреб for hawk ) was a Soviet supersonic reconnaissance drone . The first flight took place in 1960. The Tu-123 was based on the cruise missile Tu-121 .
Construction and application profile
The Tu-123 had delta wings and a conventional tail unit with pendulum elevator and rudder. With a take-off mass of 35.6 tons, the range was around 3600 km at a cruising speed of 2700 km / h and a service ceiling of 19 to 23 km. The launch took place with two PRD-52 jump starters , which accelerated the aircraft to around 600 km / h in 3.5 to 5 seconds. From this speed on, the Tumanski-R-15K-300 engine at the rear took over the drive. This delivered 98 kN of thrust.
The start takes place anywhere from mobile launch ramps . After the end of the reconnaissance flight, the Tu-123 flew to a specified target point and the engine was switched off. The container with the reconnaissance device used was dropped and landed on the parachute. Then the Tu-123 crashed and was destroyed in the process. A reusable version Tu-139 Jastreb 2 was planned, but was not fully developed.
Commitment and successor
The 52 Tu-123 built in Plant No. 64 in Voronezh were in service from 1964 to 1972. After that, their duties were taken over by the MiG-25R .
