The Tupolev Tu-22 (NATO reporting name: Blinder) was the first supersonic bomber to enter production in the Soviet Union. Manufactured by Tupolev, the Tu-22 entered service with the Soviet military in the 1960s. The last examples were retired during the early 2000s. Produced in comparatively small numbers, the aircraft was a disappointment, lacking the intercontinental range that had been expected. Later in their service life, Tu-22s were used as launch platforms for the Soviet Kh-22 standoff missile, and as reconnaissance aircraft. Tu-22s were sold to other nations, including Libya and Iraq. The Tu-22 was one of the few Soviet bombers to see combat; Libyan Tu-22s were used against Tanzania and Chad, and Iraqi Tu-22s were used during the Iran–Iraq War.

Development[]

In the 1950s, there were two primary long-range bomber design groups in the USSR, Andrei Tupolev's OKB-156, and Vladimir Mikhailovich Myasishchev's OKB-23, which had some engineers employed in Tupolev's group prior.^[1] The two groups dominated Soviet bomber design, with the twin-engine Tupolev Tu-16 medium bomber and the larger and longer-ranged four-engine Myasishchev M-4 being the front-line designs for the late 1950s. Neither aircraft had the range needed to safely attack the US; the M-4, in particular, proved to have much less range than expected and was built only in small numbers for this reason.

When the government announced a contest for a new supersonic bomber to replace these designs, Tupolev first responded with the Samolyot 103 (Plane 103), essentially a Tu-16 with four much more powerful engines, either Dobryniun VD-7s or Mikulin AM-13s. However, experience on the experimental Samolyot 98 suggested that the 103 would not have supersonic performance. They decided to start over with a blank-sheet design. After considering many possible solutions from TsAGI, chief designer Sergey Mikhailovitch Yeger eventually settled on what became Samolyot 105 in 1954. Among its features was the selection of a single pilot with no backup, which allowed the cockpit to be narrower as only one person had to be seated forward to see the runway. This had positive political aspects as it reduced crew size to three.^[1]

Both the Tupolev and Myasishchev designs were approved for prototype production in 1954. At the time, supersonic aerodynamics was still in its infancy, as were the engines that would power the designs. By this point three engines were being considered, the VD-5 and VD-7, and the new Kuznetsov NK-6. Of the three, the NK-6 offered the best performance but was still in the initial stages of development. As it was possible the design would be underpowered, much attention was spent on cleaning up the aerodynamics in order to reach the required speed. This was notable in the design of the wing and landing gear, which were designed to be as "clean" as possible, with the main wheels retracting into the fuselage to avoid requiring the wing to be thicker. Around the same time, LII wind tunnel experiments revealed a tendency for aircraft to pitch up around Mach 1. This led to the decision to move the engines from the wing roots as in the Tu-16 to an unconventional external tail-mounted position, on either side of the vertical stabilizer. This location also reduced drag.^[2]

The first prototype 105 was completed in shipped to the Flight Test and Development Base at Zhukovsky in August 1957. It flew for the first time on 21 June 1958, flown by test pilot Yuri Alasheev.^[3][4] Initial flights quickly demonstrated that the design had neither the speed nor range that was expected. It was around this time that TsAGI independently discovered the area rule for minimizing transonic aerodynamic drag, and this design was applied to 105. A key problem was that the wing root was too thick to properly exploit this effect and to further thin it a new landing gear design was introduced along with several more changes to the layout of the cabin and tail areas.^[5]

The result of all of these changes was the 105A, which first flew on 7 September 1959.^[6] Serial production of twenty examples was issued around this time, even before testing had completed. The first serial-production Tu-22B bomber, built by Factory No. 22 at Kazan, flew on 22 September 1960,^[7] and the type was presented to the public in the Tushino Aviation Day parade on 9 July 1961, with a flypast of 10 aircraft.^[8] It initially received the NATO reporting name 'Bullshot', which was deemed to be inappropriate, then 'Beauty', which was deemed to be too complimentary, and finally the 'Blinder'. Soviet crews called it "shilo" (awl) because of its shape.^[7]

While the Tu-22 was being introduced, the Strategic Rocket Forces was formed up in 1959, and Tupolev concluded that manned bombers would soon be downgraded in favor of missiles instead of "outdated and improvising means of delivery of nuclear weapons".^[5] To save the program, Tupolev proposed a long-range reconnaissance version of the aircraft, which was quickly supported by the Air Force. This became the Tu-22R, which could be modified in the field to return it to a bombing role.^[9] The first examples entered service in 1963, with a further two formations in 1965.^[10]

The Tu-22 entered service in 1962,^[7] but it experienced considerable problems, resulting in widespread unserviceability and several crashes. Amongst its many faults was a tendency for aerodynamic heating of the aircraft skin at supersonic speed, distorting the control rods and causing poor handling. The landing speed was 100 km/h (62 mph) greater than previous bombers and the Tu-22 had a tendency to pitch up and strike its tail on landing, though this problem was eventually resolved with the addition of electronic stabilization aids. Even after some of its problems had been resolved, the 'Blinder' was not easy to fly, and it was maintenance-intensive. Among its unpleasant characteristics was a wing design that allowed aileron reversal at high deflections. When the stick had been neutralized following such an event, the deformation of the wing did not necessarily disappear but could persist and result in an almost uncontrollable aircraft.

Pilots for the first Tu-22 squadrons were selected from the ranks of "First Class" Tu-16 pilots, which made transition into the new aircraft difficult, as the Tu-16 had a co-pilot, and many of the "elite" Tu-16 pilots selected had become accustomed to allowing their co-pilots to handle all the flight operations of the Tu-16 except for take-off and landings. As a consequence, Tu-16 pilots transitioning to the single-pilot Tu-22 suddenly found themselves having to perform all the piloting tasks, and in a much more complicated cockpit environment. Many, if not most of these pilots were unable to complete their training for this reason. Eventually, pilots were selected from the ranks of the Su-17 "Fitter" crews, and these pilots made the transition with less difficulty.

By the time the Tu-22B (Blinder-A) entered service, it was already obvious that its operational usefulness was limited. Despite its speed, it was inferior to the Tu-16 with respect to combat radius, weapon load, and serviceability. Soviet leader Nikita Khrushchev believed that ballistic missiles were the way of the future, and bombers like the Tu-22 were in danger of cancellation.^[11] As a result, only 15^[7] (some sources say 20) Tu-22Bs were built.

A combat-capable aerial reconnaissance version, the Tu-22R ('Blinder-C'), was developed along with the bomber, entering service in 1962. The Tu-22R could be fitted with an aerial refueling probe that was subsequently fitted to most Tu-22s, expanding their radius of operation. 127 Tu-22Rs were built, 62 of which went to the AVMF for maritime patrol use.^[12] Some of these aircraft were stripped of their camera and sensor packs and sold for export as Tu-22Bs, although in other respects they apparently remained more comparable to the Tu-22R than to the early-production Tu-22Bs.^[13]

A trainer version of the 'Blinder,' the Tu-22U ('Blinder-D'), was fielded at the same time; it had a raised second cockpit for an instructor pilot. The Tu-22U had no tail guns, and was not combat-capable. Forty six were produced.^[14]

To try to salvage some offensive combat role for the Tu-22 in the face of official hostility, the Tu-22 was developed as a missile carrier, the Tu-22K ('Blinder-B'), with the ability to carry a single Kh-22 (AS-4 'Kitchen') stand-off missile in a modified weapons bay. The Tu-22K was deployed both by DA (Long Range Aviation), and AVMF (Soviet Naval Aviation).^[15]

The last Tu-22 subtype was the Tu-22P ('Blinder-E') electronic warfare version, initially used for ELINT electronic intelligence gathering. Some were converted to serve as stand-off ECM jammers to support Tu-22K missile carriers. One squadron was usually allocated to each Tu-22 regiment.^[16]

The Tu-22 was upgraded in service with more powerful engines, in-flight refueling (for those aircraft that did not initially have it), and better electronics. The -D suffix (for Dalni, long-range) denotes aircraft fitted for aerial refueling.

Tu-22s were exported to Iraq and Libya during the 1970s. An Egyptian request was refused as a result of Soviet objections to the Yom Kippur War.^[13]

Design[]

The Tu-22 has a low-middle mounted wing swept at an angle of 55°.^[17] The two large turbojet engines, originally 159 kN (36,000 lbf) Dobrynin VD-7M, later 162 kN (36,000 lbf) Kolesov RD-7M2,^[18] are mounted atop the rear fuselage on either side of the large vertical stabilizer, with a low mounted tailplane. Continuing a Tupolev OKB design feature, the main landing gear are mounted in pods at the trailing edge of each wing. The highly swept wings gave little drag at transonic speeds, but resulted in very high landing speeds and a long take-off run.^[19][20]

The Tu-22's cockpit placed the pilot forward, offset slightly to the left, with the weapons officer behind and the navigator below, within the fuselage, sitting on downwards-firing ejector seats. The downward direction meant the minimum altitude for ejection was 350 metres (1,150 ft), which precluded their use during takeoff and landing, when most accidents occur. The crew entered the plane by lowering the seats on rails and then climbing external stepladders, sitting in the seats, and then being cranked upward into the cockpit.^[17]

The cockpit layout was also criticized by the pilots; it was filled with levers and handles that gained it comparisons to a hedgehog and some of those controls could not be reached by the pilots, who took to flying with metal hooks and other ad hoc devices. Adding to its problems was a very high panel on the right which blocked the view of the runway during landing if the aircraft had to crab against a wind from the left. This led to it being forbidden for flight by new pilots in crosswind conditions above fresh breeze on the Beaufort scale.^[17][21]

Air for the crew was provided by a bleed air system on the engine compressors. This air was hot and had to be cooled before being pumped into the cockpit. This cooling was provided by a large total-loss evaporator running on a mixture of 40% ethanol and 60% distilled water (effectively vodka). This system garnered the aircraft one of its many nicknames, the "supersonic booze carrier". As the system vented the coolant after use it was possible that the aircraft could run out during flight, and comfort had to be balanced by the possibility of running out of coolant.^[22] Numerous cases of Tu 22 crews drinking the coolant mixture and becoming paralytically drunk led to a crackdown by Soviet Air Force authorities. Access to the bombers after flights was restricted, and more frequent checks were made on coolant levels. This higher level of security, however, did not end the practice outright.

The Tu-22's defensive armament, operated by the weapons officer, consisted of a remotely-controlled tail turret beneath the engine pods, containing a single 23 mm (0.906 in) R-23 gun.^[23] The turret was directed by a small 'Argon' gun-laying radar due to the weapons officer's total lack of rear visibility (and generally much more accurate and precise fire control than optical aiming).^[6] The bomber's main weapon load was carried in a fuselage bomb bay between the wings, capable of carrying a variety of free-fall weapons: up to 24 FAB-500 general-purpose bombs, one 9,000 kg (20,000 lb) FAB-9000 bomb, or various nuclear bombs.^[7] On the Tu-22K, the bay was reconfigured to carry one Raduga Kh-22 (AS-4 'Kitchen') missile semi-recessed beneath the fuselage. The enormous weapon was big enough to have a substantial effect on handling and performance, and was also a safety hazard.^[24]

The early Tu-22B had an optical bombing system (which was retained by the Tu-22R), with a Rubin-1A navigation/attack radar.^[14] The Tu-22K had the Leninets PN (NATO reporting name 'Down Beat') to guide the Kh-22 missile.^[24] The Tu-22R could carry a camera array or an APP-22 jammer pack in the bomb bay as an alternative to bombs.^[14] Some Tu-22Rs were fitted with the Kub ELINT system, and later with an under-fuselage pallet for M-202 Shompol side looking airborne radar, as well as cameras and an infrared line-scanner. A small number of Tu-22Ks were modified to Tu-22KP or Tu-22KPD configuration with Kurs-N SIGINT equipment to detect enemy radar systems and provide compatibility with the Kh-22P anti-radiation missile.^[18]

Operational history[]

Libya[]

The Libyan Arab Republic Air Force used the Tu-22 in combat against Tanzania in 1979 as part of the Uganda–Tanzania War to help its Ugandan allies, with a single Tu-22 flying a completely unsuccessful bombing mission against Mwanza on 29 March 1979.^[25]

The Libyan aircraft were also used against Chad as part of the Chadian–Libyan conflict, with strikes into western Sudan and Chad. Libyan Tu-22s flew their first mission over Chad on 9 October 1980 against Hissène Habré's forces near the Chadian capital of N'Djamena.^[13][26] Occasional bombing raids by small numbers of Tu-22s against targets in Chad and Sudan, including a raid on Omdurman in September 1981, which killed three civilians and injured 20 others, continued to be performed until a ceasefire was arranged in November 1981.^[27]

Fighting restarted in July 1983, with Libyan air power, including its Tu-22s, being used in attacks against forces loyal to Habré, before a further ceasefire stopped the fighting until Libyan-assisted forces began a fresh offensive in early 1986. On 17 February 1986, in retaliation for the French Operation Épervier (which had hit the runway of the Libyan Ouadi Doum Airbase one day earlier), a single Tu-22B attacked the airfield at N'Djamena. Staying under French radar coverage by flying low over the desert for more than 1,100 km (700 mi), it accelerated to over Mach 1, climbed to 5,000 m (16,500 ft) and dropped three heavy bombs. Despite the considerable speed and height, the attack was extremely precise: two bombs hit the runway, one demolished the taxiway, and the airfield remained closed for several hours as a consequence.^[28][29] The bomber ran into technical problems on its return journey. U.S. early warning reconnaissance planes based in Sudan monitored distress calls sent by the pilot of the Tu-22 that probably crashed before reaching its base at Aouzou (maybe hit by anti-aircraft guns that fired in N'Djamena airport).^[30] On 19 February, another LARAF Tu-22 attempted to bomb N'Djamena once again. The Tu-22 was intercepted by a patrol of French Air Force Mirage F1Cs, and shot down 110 km (68 mi) off Chad's capital city.^[31] One bomber was shot down by captured 2K12 Kub (SA-6) surface-to-air missiles during a bombing attack on an abandoned Libyan base at Aouzou on 8 August 1987.^[32][18] One eyewitness report suggests that the pilot ejected but his parachute was seen on fire.

Another Blinder was lost on the morning of 7 September 1987, when two Tu-22Bs conducted a strike against N'Djamena. A French battery of MIM-23 Hawk SAMs of the shot down one of the bombers, killing the East German crew.^[33][34] This raid was the last involvement of the Tupolev Tu-22 with the Chadian–Libyan conflict.

The last flight of a Libyan Blinder was recorded on 7 September 1992. They are probably now unserviceable because of a lack of spare parts, although seven are visible at the Al Jufra Air Base at the following coordinates:

29°11′58.18″N 16°00′26.17″E / 29.1994944°N 16.0072694°E / 29.1994944; 16.0072694. They were reportedly replaced by Su-24s.^[35]

Iraq[]

Iraq used its Tu-22s in the Iran–Iraq War from 1980 to 1988. Offensive operations started on the first day of the war, when a Tu-22 based at H-3 Air Base struck an Iranian fuel depot at Mehrabad International Airport, Tehran, which in conjunction with other Iraqi attacks resulted in a shortage of aviation fuel for the Iranians in the early period of the war.^[36] Otherwise, these early attacks were relatively ineffective, with many raids being aborted owing to Iranian air defences and operations being disrupted by heavy Iranian air strikes against Iraqi airfields.^[37] Iran claimed three Tu-22s shot down during October 1980; one on 6 October over Tehran, and two on 29 October, one near Najafabad by an AIM-54 Phoenix missile launched by an F-14 interceptor and one over Qom.^[38]

Iraq deployed its Tu-22s during the War of the Cities (along with Tu-16s, Su-22s and MiG-25s), flying air-raids against Tehran, Isfahan and Shiraz, with these attacks supplemented by Iraqi Scud and Al Hussein missiles. Iran retaliated against Iraqi cities with its own Scuds.^[39][40] The Iraqi Air Force were particularly enthusiastic users of the gargantuan 9,000 kg (20,000 lb) FAB-9000 general-purpose bomb, which skilled Tu-22 pilots could deploy with impressive accuracy, using supersonic toss bombing techniques at stand-off distances and allowing the aircraft to escape retaliatory anti-aircraft fire. Usage of the FAB-9000 was so heavy that the Iraqis ran low of imported Soviet stocks and resorted to manufacturing their own version, called the Nassir-9.^[34]

Iraqi Tu-22s were also deployed in the last stages of the "Tanker War". On 19 March 1988, four Tu-22s together with six Mirage F.1s carried out a raid against Iranian oil tankers near Kharg Island. The Tu-22s sank one supertanker and set another on fire, while Exocet missiles from the Mirages damaged another tanker.^[26][41] A second strike against Kharg Island later that day was less successful, encountering alerted Iranian defences, with two Tu-22s being shot down. These were the final operations carried out by Iraq's Tu-22s during the Iran–Iraq war. Iraq lost seven Tu-22s during the war, with several more badly damaged.^[26][41] The remaining Iraqi Tu-22s were destroyed by American air attacks during the 1991 Gulf War.^[42]

Soviet Union[]

The only Soviet combat use of the Tu-22 occurred in 1988, during the Soviet withdrawal from the war in Afghanistan. Tu-22P Blinder-E electronic jammers were given the task of covering the withdrawal route back to the Soviet Union. Radar-jamming Tu-22PD aircraft covered Tu-22M3 Backfire-C bombers operating from the Mary-2 airfield in the Turkmen SSR on missions in Afghanistan near the Pakistani border. They protected the strike aircraft against Pakistani F-16 air defence activity and suppressed radar systems which could aid Pakistani F-16 attacks on the Soviet bombers in the border region.^[43] Tu-22PD crews were also tasked with photo-reconnaissance missions, to assess bomb-damage, in addition to their primary electronic warfare missions.^[44]

The Tu-22 was gradually phased out of Soviet service in favor of the more-capable Tupolev Tu-22M. At the time of the dissolution of the Soviet Union there were 154 remaining in service, but none are now believed to be used. The Tu-22M was still in use as of 2017.

A total of 311 Tu-22s of all variants were produced, the last in 1969. Production numbers were following: 15 of bomber version (B), about 127 of reconnaissance versions (R, RD, RK, RDK and RDM), 47 of ELINT versions (P and PD), 76 of missile carriers (K, KD, KP and KPD) and 46 of training versions (U and UD).
