SOVIET RECONNAISSANCE DRONES
Information on drones built in the USSR is extremely sketchy and contradictory. It appears that the Tupolev design bureau began work on drones for
target use in the mid-to-late 1950s, and has produced a number of different types since that time
One of the earliest Soviet reconnaissance drones was the big "Tu-123 Yastreb (Hawk)", sometimes referred to as the "DBR-1", introduced in 1964.
This was a long-range, high-altitude supersonic strategic reconnaissance machine, in the form of a big dart, conceptually somewhat similar to the US
D-21. It carried both film cameras and SIGINT payloads. The Tu-123 was ground-launched with RATO booster and powered by a KR-15 afterburning turbojet
in flight. The Tu-123 was expendable, parachuting its payload to the ground for recovery.

The lack of recovery capability was unsatisfactory. This concern led to the "Tu-139 Yastreb 2", which could land on unprepared airstrips, but it was
never put into production, as by that time the Soviets had shifted their emphasis to low-level reconnaissance. The Lavochkin bureau also designed a
tactical reconnaissance UAV, the "La-17R", for which details are unclear.
* Tupolev followed the Yastreb with two other lines of reconnaissance UAVs, including the "Tu-141 Strizh (Swift)", and the "Tu-143 Reys (Flight)"
and its successors.
The Tu-141 was a relatively large, medium-range reconnaissance UAV. It was another dartlike machine, with a rear-mounted delta wing, forward-mounted
canards, and a KR-17A turbojet engine mounted above the tail. It could carry a range of payloads, including film cameras, infrared imagers, EO
cameras, and imaging radar. The Tu-141 was in Soviet service from the late 1970s to the early 1980s, and was provided to Soviet allies after that.
TUPOLEV TU-141 STRIZH:
...spec.........................metric.........................english
wingspan................3.875 meters..........12 feet 8 inches
length......................14.33 meters......................47 feet
launch weight............5,370 kilograms.....11,840 pounds
cruise speed............1,000 KPH............620 MPH / 540 KT
service ceiling.............6,000 meters............19,700 feet
range.......................1,000 KM............620 MI / 540 NMI
The Tu-143 was introduced in the early 1980s and strongly resembled the Tu-141, but was substantially scaled-down. It was a short-range tactical
reconnaissance system, and had a low-level flight capability. It was truck-launched with RATO booster, recovered by parachute, and powered by a
TR3-117 turbojet with 5.79 kN (590 kg / 267 lb) thrust. The initial version carried film cameras, but later versions carried a TV or radiation
detection payload, with data relayed to a ground station over a datalink.
TUPOLEV TU-143 REYS:
...spec...............................metric................english
wingspan..................2.24 meters............7 feet 4 inches
length........................8.06 meters..........26 feet 5 inches
height.........................1.54 meters............5 feet 1 inch
launch weight...............1,230 kilograms....2,710 pounds
maximum speed..........950 KPH............590 MPH / 515 KT
service ceiling..............5,000 meters...........16,400 feet
range......................200 KM.............125 MI / 110 NMI
The Tu-143 was apparently used by Syria in reconnaissance missions over Israel, as well as by Soviet forces in Afghanistan. A target drone version,
the "M-143", was introduced in the mid-1980s.
The Tu-143 was followed into service in the late 1980s by the similar but improved "Tu-243 Reys-D", with a 25 centimeter (10 inch) fuselage stretch,
to provide greater fuel capacity and about twice the range; an uprated TR3-117 engine with 6.28 kN (640 kg / 1,410 lb) thrust; and improved
low-altitude guidance. Tupolev has been promoting the further refined "Tu-300", which resembles its predecessors but is fitted with a nose antenna
dome and nose fairings for modern sensors and electronic systems.
As with most Soviet-Russian UAVs, details of the Tu-300 are unclear. As new information on Soviet and Russian aircraft has been slowly leaking West
since the fall of the USSR, hopefully more data will presently come to light to clarify the certainly incomplete and probably muddled information now
available.
This some more info on the TU series UAVs.
