Tu-22M: I haven't said everything yet!
As we have already said, fifty years is often not a long time for an aircraft if it is a good aircraft.
The Tu-22M, which became the successor to the Tu-22, differing from it in everything except for the number, the aircraft is more than peculiar, but today we will talk about how “in the know” it is and whether it is worth counting on it in military conflicts of the future.
Tu-22M0
First flight in 1969. It was originally created as part of the "106" project, that is, a radical modernization of the Tu-22, which was an aircraft whose combat value was in doubt. By the time work began on the 106 project, the concept of using bombers in the world had changed and the Soviet Air Force came to the conclusion that the so-called dual-mode aircraft was needed. That is, an aircraft that was supposed to be suitable for supersonic high-altitude flights, long-range flights at subsonic speeds, and low-altitude flights at transonic speeds.
All these requirements in the aggregate looked very contradictory, but an aircraft with a variable sweep wing could meet them under a successful set of circumstances. Takeoff at the minimum sweep angle of the wing and further supersonic flight at maximum angles of attack.
For everything, as they say, you have to pay, and in our case we had to pay with an increase in the mass of the structure, since the wing turning systems, already massive, required further strengthening of the entire fuselage structure.
Work on the project of a new long-range missile carrier "145" was started in 1965, moreover, on an initiative basis. After all, at that time the plane, which was presented as a "killer of aircraft carriers", was already in service - the T-4 designed by the Sukhoi Design Bureau. So in the Tupolev Design Bureau, work was carried out semi-legally, under the guise of modernizing the Tu-22. But the result was a plane that had nothing to do with the original prototype at all.
As a result, after many alterations, the final appearance of the aircraft was formed: a mid-wing with a variable sweep wing and a fixed middle part of the wing, which had a sweep angle of 65 degrees. The movable part could occupy fixed positions of 20, 65 and 72 degrees.
Each of the positions corresponded to a precisely calculated optimal aerodynamic configuration of the aircraft for a certain flight mode:
20 degrees - for takeoff, landing and flight at maximum range in subsonic mode;
65 degrees - for long-range flight at supersonic speed;
72 degrees - for flight at transonic speeds at low altitudes.
The aircraft could develop a maximum speed of 1100 km / h at an altitude of 50 to 100 meters. In general, this altitude range was inaccessible to the bombers of that time.
At an altitude of 14 m, the maximum speed was 500 km/h.
Cruising supersonic speed was 2200 km / h.
In general, it was planned to use the new aircraft as a strike aircraft from medium and high altitudes. In the face of strong anti-aircraft defense, the aircraft had to overcome it at ultra-low altitudes (up to 200 m) at a speed of 1100-1200 km / h. There was a certain chance to “slip through” and hit the target with rockets or bombs. The targets were missile launchers of both mobile and silo placement.
In addition to the bomber, it turned out that the aircraft could be used as a high-altitude missile carrier by arming it with the Kh-22 missile. This multifunctional missile, depending on the GOS, could destroy a variety of targets. The aircraft could also be used as a reconnaissance, jammer and anti-submarine defense aircraft. This was facilitated by a large carrying capacity, a decent size bomb bay and powerful power sources.
Compared with the Tu-22, significant work was carried out to equip the crew. The experience of operating the Tu-22 was taken into account, as a result of which the navigator's cockpit was moved behind the cockpit, the operator's cockpit was shifted back and turned to face along the flight. The most important alteration was the system for ejecting the crew up, and not down, as on the Tu-22. This made it possible to save the crew in the height range from 10 meters, while for the Tu-22 the minimum ejection height was 350 meters.
The redesign of the cockpit made it possible to introduce a second pilot into the crew, who was placed next to the first pilot / crew commander. During the alterations, the navigational and operator's cabins were combined, creating a compartment for two.
The reshaping of the cockpit also affected the wing. The sweep of the middle, fixed part of the wing was reduced to 56 degrees, and the angle of change of the sweep of the turning parts was made smoothly varying from 20 to 60 degrees with the possibility of fixing in any position. They refused to place ailerons in the moving part of the wing, but they introduced spoilers and a deflectable stabilizer, and slats were installed to improve takeoff and landing.
The engines were placed on the sides of the aircraft. In general, the scale of changes in comparison with the Tu-22 made it possible to say that a new aircraft had actually turned out, which differed not only externally, but also internally. Only the bomb bay and payload remained unchanged.
For two years at the Tupolev Design Bureau they worked on the aircraft, and finally, in November 1967, the official Decree of the Council of Ministers of the USSR No. 1098-378 on the Tu-22M was issued, according to which the design bureau was tasked with designing a modification of the Tu-22K - Tu-22KM with a variable sweep wing and two DTRDF NK-144 (NK-144-2).
This missile carrier was planned as a carrier of one Kh-22 missile. This monster weighing 5,5 tons and 11,5 meters long could carry a nuclear warhead with a capacity of up to 1 megaton or a cumulative fragmentation weighing 1 ton. The rocket flew on a mixture of the most dangerous substances, which made its use very difficult. But it was weapon, capable of sweeping a strike aircraft carrier grouping of a potential enemy (that is, the United States) from the water surface, therefore the carrier was necessary.
The process of creating a missile carrier according to the requirements of the military dragged on for as long as 10 years. Appetites flared up as the Tupolev Design Bureau worked out one task after another.
The Air Force insisted on strengthening the bomb load so that, in addition to the rocket, the new aircraft could take up to 3 tons of bombs, in order to have decent defensive weapons, the aft gun mount had to be equipped with radar and television sights, and in addition to them, the aircraft had to be equipped with jamming equipment.
As a result, the Design Bureau worked out two versions of the aircraft: with a stern gun mount and with a unified tail compartment with electronic warfare equipment. But that was only the beginning.
Further, a number of requirements were put forward to strengthen the strike capabilities of the aircraft, which very much took the car away from what was originally required in the Decree of the Council of Ministers. As a result, the new aircraft was required to take THREE X-22 missiles, and increase the bomb load to 24 tons. That is, a sort of Tu-95, but supersonic. In reality, three X-22s could be suspended, but in such an overloaded version, by about 4 tons, that it would definitely not be necessary to talk about a normal flight.
And without that, the plane, which had been worked out for quite a long time, was overgrown with new products that rained down on it one after another. New navigation complex NK-45, automatic on-board control system ABSu-145m, new instrumentation, radar and flight equipment. Yes, this definitely improved the aircraft, but it took time, time and time again for debugging and testing. Because the Tu-22M for more than 10 years did not leave the stage of bringing to the standard.
But by August 1969, all work was completed and the aircraft made its first flight. Further, everything went as it was with other machines: the first began to fly around and test, at the same time, construction of an experimental batch of five Tu-22Ms began in Kazan for comprehensive testing. Another five aircraft were built for the Long Range Combat Training Center. aviation in Ryazan, where the process of retraining crews for new equipment began.
And then thunder struck. During the tests, the Tu-22M0 did not show the declared results. With one X-22 missile powered by NK-144-22 engines, the aircraft showed a maximum speed of only 1540 km / h instead of 2200 km / h, and a range at subsonic cruising speed of 4140 km instead of 7000. To take off, a 120-ton machine needed a runway of 2600 meters .
In general, the Air Force was disappointed and, having not entered service, before reaching the stage of serial construction, the Tu-22M went for modernization. More precisely, the modernization work began before the start of flight tests, the Tupolev Design Bureau was also not stupid, and they understood that the machine, obviously overweighted by the military’s Wishlist, would not give even half of the expected results.
So the Tu-22M0 began to be converted into the Tu-22M1 long before the aircraft received a residence permit at the airfields.

Tu-22M1
We will not focus on this version of the Tu-22M, since a total of 9 aircraft and one airframe for static tests were manufactured. All aircraft were involved in the test program, three of them were lost in accidents. Five aircraft were transferred to the 33rd Naval Aviation Combat Training Center in Nikolaev, where they were subsequently cut into metal. One Tu-22M1 ended up in private hands in Latvia and is located in Riga, on the territory of the aviation museum.
Tu-22M2
Work on bringing the Tu-22M to the level of the requirements of the Decree of the Council of Ministers of 1967 went in almost the same direction: more powerful engines were needed, then all problems would be solved.
The new NK-25 engines or the improved NK-22 could solve the issue of speed. Plus, work was carried out to reduce the weight of the aircraft, which, although they gave some improvement by 1,4-1,5 tons, but they should not be called successful.
In general, the aircraft was considered as a long-range missile carrier armed with the K-22M complex and capable of carrying three Kh-22 missiles. But if necessary, the missile carrier had to "be able" to use conventional bombs. Moreover, the conversion into a bomber should have been as simple as possible and technicians in the field had to cope with it.
The lead Tu-22M2 made its first flight on May 7, 1973, tests and various refinements went on until 1975 inclusive. Flight characteristics have increased somewhat compared to the Tu-22M0, but only an inveterate optimist would call these improvements cardinal.
The takeoff run was reduced to 2 m (-300 m).
Range at subsonic speed increased to 5100 km (+ almost 1000 km).
The maximum speed has increased to 1660 km/h (+ 130 km/h).
Maximum speed without rocket 1800 km/h (+110 km/h).
The work was carried out simply on a huge scale and gave a certain result. The result was the adoption of the Tu-22M2 into service in August 1976. The Tu-22M2 was in serial production until 1983, in total, the Kazan Aircraft Plant built 211 Tu-22M2.
In the flight units of the Long-Range Aviation and Navy Aviation, where the Tu-22M2 began to arrive, it was met more calmly than the Tu-22. I liked the plane. The general refinement of the machine, modern equipment, which gave more opportunities in flight, improved ergonomics of the crew's workplaces and the inclusion of a co-pilot, played their role here. All this made it possible to work more efficiently, especially in long-distance flights, for which the Tu-22M2 was sharpened.
But I especially liked the system of "normal" ejection, up, which removed the restrictions on the minimum height of the emergency escape of the aircraft. Tu-22 and all the negativity associated with it, gradually left and was forgotten.
Although the Tu-22M2 was not equipped, like the American B-1 bomber, with an automatic terrain avoidance system, it was capable of making relatively long low-altitude “throws”, evading enemy air defenses. This also played a significant role in the evaluation of the aircraft.
In the 70s, information about the Tu-22M penetrated into NATO and caused quite a decent concern there. After analyzing the performance characteristics of the aircraft, which the bloc's scouts were able to obtain, NATO came to the conclusion that the USSR had created a new intercontinental strategic carrier of nuclear weapons capable of reaching the United States. This was not entirely true, of course, in theory, with several refueling, the Tu-22M could fly to the United States, but the aircraft was not created for this at all.
Nevertheless, the Tu-22M2 became one of the main characters in the SALT-2 negotiations between the US and the USSR. The United States really wanted to "kill" this plane and they almost succeeded. At least within the framework of SALT-2, the USSR undertook to limit the production of Tu-22M2 to three dozen per year, and the in-flight fueling equipment from already produced aircraft was dismantled. This significantly reduced the value of the entire complex as a whole. From a long-range missile carrier, an ordinary heavy bomber turned out.
Nevertheless, the modernization program was not curtailed and work on bringing the aircraft in the 70s to the level laid down in 1967 continued. Actually, there was only one problem - the engine. NK-22 could not be brought to the design power in terms of thrust and fuel consumption. That is, it had to be changed. NK-23, which was a forced version of NK-22, could not solve the problems and did not go into the series. The NK-23 engine generally showed that the entire line of NK-144 - NK-23 has exhausted itself to the end.
With superhuman efforts, a new engine was created in the Kuznetsov Design Bureau, called the NK-25. It was a two-circuit turbojet three-stage engine with a common afterburner and an electronic control system ESUD-25, which made it possible to optimize engine operation in a variety of modes.
The maximum takeoff thrust of the NK-25 was 25 kgf, while the design 000 kgf could not be achieved from the NK-22. More powerful, the NK-22 was also more economical than the NK-000.
It was the appearance of the NK-25 that became the first step in the creation of the Tu-22M3.

Tu-22M3
The new version of the aircraft made its first flight in 1977. By that time, the Soviet Air Force command was puzzled by the possibility of carrying new aeroballistic missiles by aircraft. This was required by the program of rearmament of the air force and strategic forces of the Soviet Union.
On the basis of the Tu-22M2 aircraft, a number of tests of new weapons, Kh-22MP and Kh-28 missiles, were carried out. The X-28 was intended to destroy working radars, including those on ships. In 1979, tests of the K-22MP complex with the Kh-22MP missile were successfully completed and the complex was recommended for adoption.
The need to modernize the carrier was also understood and implementation work was underway. The NK-25 engine has passed comprehensive tests on Tu-22M2 and Tu-142LL laboratories. The development of the engine took four years.
At the same time, the Kuznetsov Design Bureau was working on an even more promising NK-32 engine, which was generally planned to be made common for all heavy attack aircraft, both Tu-160 and Tu-22M. Initially, the Tu-160 was designed for the NK-25, but first these engines went to a new modification of the Tu-22M3. And largely thanks to them, the plane began to sparkle with new colors.
In June 1974, a Government Decree was adopted, which determined the further development of the Tu-22M with NK-25 engines and a new weapon system. The version was officially named Tu-22M3.
Modification or modernization of the Tu-22M2 into the Tu-22M3 is a whole range of works that again greatly changed both the appearance of the aircraft and its content:
- NK-22 engines were replaced by NK-25;
- the refueling system was returned to the aircraft;
- changed the bow and the fuel receiver rod itself;
- air intakes with a vertical wedge replaced air intakes with a horizontal wedge;
- the maximum deflection angle of the wing was increased to 65 degrees;
- the stern gun mount became single-barreled;
- fire bulkheads steel titanium;
- carried out a set of works to lighten the aircraft structure, which caused a weight reduction of 2300-2700 kg;
- stable frequency generators appeared in the electrical system;
- reworked the chassis system and switched to a different type of wheels and many other changes.
It was planned to significantly expand the range of weapons, install a new Obzor radar, and install an electronic warfare complex instead of individual electronic warfare devices. And most importantly, all these measures were supposed to eventually bring the aircraft to the values laid down in the decree of 1967. Even after 10 years.
In fact, if all the innovations could be implemented, it would again be a new aircraft, different from the Tu-22M2 as the Tu-22M was different from the Tu-22. They even decided to give the plane a new name - Tu-32. But alas, much of what was planned could not be implemented for a number of reasons, so the aircraft was named Tu-22M3.
But in this form, the Tu-22M3 first took off from the ground in June 1977. After eliminating the shortcomings found during comprehensive tests, the Tu-22M3 was put into serial production in 1978, and until 1983 the Tu-22M3 was built in parallel with the Tu-22M2, and since 1984 only Tu-22M3 was mass-produced. Serial production of the Tu-22M3 was discontinued in 1993.
Tests and the start of operation of the Tu-22M3 showed that in terms of their flight and tactical characteristics, the aircraft of the new modification are significantly superior to the Tu-22M2. Moreover, they really managed to reach the level of indicators of 1967 and even surpass them somewhat. The tests were completed in 1981, but until 1984 the aircraft underwent an additional test cycle, including for equipping with aeroballistic missiles. New weapons systems required more time to fine-tune and refine them, but in our case there was no rush at all, the Tu-22M2 coped well with the tasks assigned to it.
So, despite the fact that in 1981 the Tu-22M3 was recommended for adoption, the actual adoption took place only in 1989.
Practically, in terms of flight characteristics, it was possible to reach the requirements of 1967, with a significant increase in the combat capabilities of the aircraft and the entire complex. Joint state tests of the Tu-22M3 were completed in 1981, and the aircraft was recommended for adoption.
From 1981 to 1984, the aircraft passed an additional set of tests in the version with enhanced combat capabilities, including in the version equipped with aeroballistic missiles. New weapons systems required additional time for their refinement and testing, so in the final form, the Tu-22М3 was officially accepted for service only in March of the 1989 year.
And from that moment on, the Tu-22M3 performs the tasks of deterring and countering sea and land strike formations of a potential enemy. The aircraft was repeatedly used in military conflicts: Afghanistan, Chechnya, South Ossetia, Syria, Ukraine. The use of Tu-22M3 armament showed its effectiveness, despite the fact that the aircraft was mainly used in a bomber configuration. Losses for all time amounted to 1 aircraft, which was shot down during the enforcement of Georgia to peace.
Aircraft armament today is a very impressive force. The "main caliber" is the X-22N missiles, which the Tu-22M3 can take up to three pieces. One missile is suspended under the fuselage in a semi-recessed position, two missiles are placed under the wing. It is possible to carry Tu-22M3 Kh-15 short-range aeroballistic missiles, which the aircraft can take up to 10 pieces. Six missiles are placed on a drum launcher in the bomb bay, and four on external hardpoints.
Bomb weapons, consisting of free-falling bombs (both conventional and nuclear) with a total mass of up to 24 kg, are located in the fuselage (up to 000 kg) and on four external suspension units on beam holders. The easiest accommodation option is 12 FAB-000 or 69 FAB-250. Used with Tu-8M1500 and heavier FAB-22.

Now let's talk about perspectives.
The fact that the Tu-22M3 has a certain potential for modernization is a fact. The aircraft is able to work not only against aircraft carrier formations, it generally has a wide range of targets both at sea and on land. Let's put it this way: the Tu-22M3 is a modern means of delivering weapons in military conflicts. Diverse. From cruise missiles to nuclear bombs.
The base was laid in the distant sixties just fine. It remains only to maintain the existing aircraft at the proper level, as long as the resource of the gliders allows it. Farther? Further production and modernization is possible. The aircraft will remain "in the know", despite the time, especially if the onboard radar equipment and weapons are updated.
Tu-22M3M
As an example, the contract announced back in 2012 for the modernization of about three dozen Tu-22M3s to the level of Tu-22M3M.
The latest electronic equipment that will allow the use of modern high-precision weapons, such as Kh-32 missiles. Today, the Russian Aerospace Forces has about 115 Tu-22M3 units, of which only about 40 vehicles are combat-ready. Of these, 30 vehicles are being upgraded at the first stage. The rest is a question. So far, in 2018, one aircraft was converted, which began to be tested.
During the modernization, the Tu-22M3 will receive the same electronic equipment and engines as the latest Tu-160M2. The modernization will affect all avionics, including the navigation and sighting system, the aircraft will be able to carry and use, in addition to the Kh-32, up to 4 Kh-47 Kinzhal hypersonic missiles, as well as long-range cruise missiles: the air version of the Caliber, (" Product 715"), X-101, X-555.
What is the main problem in the world today for all air commanders? The problem of air defense systems that are evolving at a cosmic pace. And the second: the increase in the cost of aircraft. Both problems today have reached such a level that it is cheaper to leave aircraft on the ground than to expose them to modern air defense systems.
Therefore, a cheap aircraft that has a chance of breaking through air defense barriers is a very useful thing in the arsenal. Yes, 40 bombers, albeit long-range ones, are not something that can scare NATO or Europe. Considering that in the Soviet years more than 500 Tu-22M aircraft of all modifications were manufactured.
However, there is a certain reserve that can and should be used. 115 aircraft are 8 full-fledged regiments in the DA of the Russian Aerospace Forces. This is power.
It may seem to someone that it would be worthwhile to direct efforts to create something such as always "not having ...". However, if you look at what our opponents are doing, then just the opposite is true - with all their might they “drag” very old planes into tomorrow. Yes, and we, too, for example, the same Su-24M2, which are equipped with more or less modern avionics SVP-24-22, are quite relevant today.
And since the SVP-24-22 can also be installed on the Tu-22M3M, the missile carrier can be turned into an aircraft to break through the air defense systems of European countries, equipping it with anti-radar missiles and other high-precision products.
It is assumed that the Tu-22M3M will receive the NV-45 radar station, which in turn is a descendant of the Novella-P38 search and sighting system, which was very good for its time, which was equipped with Il-38N anti-submarine aircraft.
If NK-32-02 engines (like the Tu-160M2) and modern electronics are added to this, which will make it easier both to control the aircraft in flight and to aim and hit targets in battle, the full range of Kh-32, Kh-55, X-555, X-101/102, promising X-50, and ...
Why not? Yes, Dagger.
The Tu-22M3M flies, of course, not at the same speed as the MiG-31, because the upper stage is somewhat worse. But the range is 1000 km more than that of the interceptor, and the "Daggers" by weight can take at least four. Two will be on the middle part of the wing, and two, for example, on the turret in the bomb bay.
And here's something for everyone in Europe to think about. The United States is far away, but for Europeans, especially for those who like to rattle weapons and shout towards the borders of Russia, this is a very reason for reflection. A hundred "Daggers" is, excuse me, a hundred "Daggers", which are almost impossible to reflect.
Yes, perhaps, it is not worth saying goodbye to the Tu-22M. He really hasn't said his last word yet.
