The Tupolev Tu-22M (also known as Backfire) is a long-range strategic and maritime strike bomber developed by Tupolev for the Soviet Air Force. The aircraft is currently in service with the Russian Air Force and Russian Naval Aviation.
The Tu-22M was based on the design of the Tu-22 aircraft. The first Tu-22M-0 prototype completed its maiden flight in August 1969. The Tu-22M-1 first flew in July 1971 and the Tu-22M was first deployed in combat missions in Afghanistan between 1987 and 1989. The Tu-22M3 was used by Russia for combat operations in Chechnya in 1995.
The aircraft is primarily used to conduct nuclear strike and conventional attack operations. It can also be deployed in anti-ship and maritime reconnaissance missions.
Tupolev Tu-22M variants
The earliest pre-production aircraft produced was the Tu-22M0. Its production was limited to small numbers due to inadequate performance. It was followed by the Tu-22M1 pilot-production aircraft for the Soviet Naval Aviation.
Production on the first major production version, Tu-22M2 began in 1972. It was equipped with extended wings and a redesigned fuselage, twin engines and a new undercarriage.
The Tu-22M3 was introduced with upgraded features to overcome the shortfalls of its predecessor. The aircraft completed its first flight in June 1977 and was inducted into the inventory in 1983. Some of the Tu-22Ms were also modified to Tu-22MR and Tu-22ME standard.

It’s equipped with an advanced electronic system SVP-24-22 (similar to the one of Su-24 airplane), which was developed by the JSC “Gefest and T”. It provides automatic guidance to the target and if necessary recalculates the parameters of the attack during flight. It has also the capability to guide a group of planes to the target from various directions and can land the aircraft of its own, if the weather conditions are bad. This system has significantly improved the navigation and targeting from a long distance, without having to approach the target and once the rocket is fired, it is very difficult to be locked and destroyed.

30 Tu-30M3 to be upgraded to Tu-22M3
In 2012, the range of airborne and ground equipment SVP-24-22 to be erected in four distant supersonic missile-bomber Tu-22M3. This was stated by Director General of “Hephaestus and T” Alexander Panin, in an interview to ITAR-TASS. This company is the creator of the modification of the complex SVP-24 which already quite successfully operated on the modernization of Russian Sukhoi Su-24.
With all of this emphasizes that the installation of SVP-24-22 provides separate applets and will be implemented regardless of the plans for the modernization of the deepest, which are subject to 30 missile carriers Tu-22M3. The new complex SVP-24-22 allows you to more effectively perform combat tasks and navigation also achieve improved accuracy hell aircraft systems failure. In addition, the complex provides a clear set of military aircraft to land in bad weather and with no land kursoglissadnyh systems. System SVP-24 avionics for all that is versatile and can be installed on many types of aircraft and helicopters of the Russian Air Force, including the bombers Tu-22M3 and Su-24M or attack helicopters Ka-52. Another advantage is its undisputed fact that this system allows to reduce ground time of preparation and control of the aircraft at 4-5. Tu-22M3, one flight hour which asks 51-man hours of engineering support, it’s pretty basic.
“30 aircraft will be quite in order to bring down one American aircraft carrier”
Sivkov Constantine, who is a physician of Military Sciences and the first vice-president of the Academy of Geopolitical problems, pointed out that the modernization implies a complete substitute for navigation, weapons control and communications, and will cost from 30% to 50% of the price of the aircraft. With all of this upgrade to version 30 aircraft Tu-22M3M do better fighting ability Park Tu-22M3 20%. According to him, the modernization of only 30 aircraft will be quite in order to bring down one South American aircraft carrier sunk with all this, a number of escort ships. While upgrading the entire fleet of bombers Tu-22M3 is permitted to raise their efficiency by 100-120% for offshore facilities and 2-3 times the action on land targets. Source survincity.com
Introducing the SVP-24
SVP stands for “специализированная вычислительная подсистема” or “special computing subsystem”. What this system does is that it constantly compares the position of the aircraft and the target (using the GLONASS satellite navigation system), it measures the environmental parameters (pressure, humidity, windspeed, speed, angle of attack, etc.). It can also receive additional information from datalinks from AWACs aircraft, ground stations, and other aircraft. The SVP-24 then computes an “envelope” (speed, altitude, course) inside which the dumb bombs are automatically released exactly at the precise moment when their unguided flight will bring them right over the target (with a 3-5m accuracy).
In practical terms this means that every 30+ year old Russian “dumb” bomb can now be delivered by a 30+ year old Russian aircraft with the same precision as a brand new guided bomb delivered by a top of the line modern bomber.
Not only that, but the pilot does not even have to worry about targeting anything. He just enters the target’s exact coordinates into his system, flies within a defined envelope and the bombs are automatically released for him. He can place his full attention on detecting any hostiles (aircraft, missiles, AA guns). And the best part of this all is that this system can be used in high altitude bombing runs, well over the 5000m altitude which MANPADs cannot reach. Finally, clouds, smoke, weather conditions or time of the day play no role in this whatsoever.
Last, but not least, this is a very *cheap* solution. Russian can now use the huge stores of ‘dumb’ bombs they have accumulated during the Cold War, they can bring an infinite supply of such bombs to Syria and every one of them will strike with phenomenal accuracy. And since the SVP-24 is mounted on the aircraft and not the bomb, it can be reused as often as needed.
The SVP-24 has now been confirmed to be mounted on the Russian SU-24s, SU-25s, Tu-22M3 “Backfires” and the Kamov Ka-50 and Ka-52 helicopters, the venerable MiG-27 and even the L-39 trainer. In other words, it can be deployed on practically *any* rotary or fixed wing aircraft, from big bombers to small trainers. I bet you the Mi-24s and Mi-35Ms deployed near Latakia also have them.
Here are what the various parts of the SVP-24 system look like (photo from the MAKS Air Show inZhukovsky):
The SVP-24 proves, yet again, the good engineering, especially good military engineering does not have to be expensive or flashy. In practice the introduction of the SVP-24 in the RASF resulted in a net reduction in operating costs. Source thesaker.is
New data on Tu-22M3M modernization
New details have appeaed on this aircraft’s modernization. According to the data posted by alexeyvvo at forums.airforce.ru, a NV-45 radar is being installed. This model, manufactured by Leninets, derives from the P-38 Novella used in Il-38N. So far there are no details on the performance. The P-38 can track detect targets at 320 kms. The cost of 4 NV-45 sets is 8.33 million $.
The installation shows that the main mission of Tu-22M3M will be ground attack/strike. A few years ago there were talks about installing a radar similar to the Su-35 and air to air missiles. Source lejandro-8en.blogspot.com

The main armament of the Tu-22M3 is a combination of three X-22MA missiles (one under the fuselage and two under the wings). The missile is intended against naval or ground targets and the destruction of anti-air defense locations. It has a range of 140-150 km, weights 5.900 kg and travels at about 4 Mach. Besides the X-22MA missile, the aircraft can also carry the X-15 missiles for attacking naval targets with a millimeter wave length sensor for passive guidance against radars. Source redstar.gr
Kh-22 Kitchen (AS-4 KITCHEN)
The “Kh-22” missile (NATO codename “AS-4 Kitchen)”, part of the “K-22” weapons system, was a supersonic rocket powered weapon. It had a pencil-shaped fuselage, with twin delta wings and a cruciform tail assembly; the bottom tailfin folded sideways to provide takeoff clearance. The rocket was liquid-fueled, using storable hydrazine and nitric acid propellants, and has two rocket chambers, one for boost and one for long-range cruise.
The Kh-22 was guided by a gyroscopic INS, with a Doppler radar altimeter. The guidance system was evaluated on modified MiG-19 fighters. There were three initial variants: the “Kh-22”, an anti-ship variant with an active radar terminal seeker and a conventional warhead; the “Kh-22P”, a “defense suppression” variant with a passive radar homing terminal seeker and a nuclear warhead, intended to crush adversary air-defense sites; and the “Kh-22N” version for strategic attacks. The missile performed a high-altitude pop-up attack to descend on the target at Mach 2.5. It followed a “semi-ballistic” trajectory, with either a relatively shallow pop-up to medium altitudes followed by a Mach 1.2 dive towards the target, or a stratospheric pop-up followed by a Mach 2.5 dive towards the target.
Raduga began work on the Kh-22 in 1958 and it was first deployed in the mid-1960s. A Bear bomber could carry one under the centerline; it also had a pylon mounted on each wing close to the wing root, allowing it to carry two Kh-22s. Pictures exist of Bears carrying three Kh-22s but this was apparently not a practical operational load. One can be carried under the belly by the “Tu-22 Blinder” or “Tu-22M Backfire” supersonic bombers, with another possibly carried under each wing.
In the 1970s, two improved variants were introduced: the “Kh-22M”, for anti-ship and precision land attack, with a new HI-LO attack profile; and the “Kh-22MA”, with a LO-LO attack profile. Both variants added improved counter-countermeasures and a datalink for course corrections. The Kh-22 was obsolescent by the late 1970s but has lingered on since that time. Source craymond.no-ip.info

KH-15 (AS-16 KICKBACK)
Even the fast KSR-5 left something to be desired. Storable rocket propellants are corrosive and highly toxic, making them difficult to handle, and the KSR-5’s range and capability were inadequate. In the 1970s, the US Navy developed the Grumman F-14 Tomcat interceptor, which featured long-range Phoenix air-to-air missiles. The Tomcat / Phoenix combination, backed up by the Grumman E-2C Hawkeye carrier-based radar early warning aircraft, presented a clear threat to Soviet bombers operating in the anti-ship role. The Hawkeye could provide long-range “eyes” for the Tomcat, which had long range and endurance, allowing it to fire a Phoenix at a Soviet bomber long before the Red aircraft got within range of a carrier group. If the bomber did manage to take a shot with a cruise missile, the Phoenix might well shoot the missile down.
The Tomcat / Phoenix / Hawkeye threat led the Soviets to develop the low-level launch versions of the Kh-22 and KSR-5 missiles, and also to work on a missile that was much harder to intercept. The Soviets were impressed enough by the Boeing SRAM that Raduga developed an equivalent, the “Kh-15 (AS-16 Kickback)”, which has almost the same external appearance as the SRAM. It was the first Soviet large ASM with solid-fuel rocket propulsion.
The Kh-15 is a simple spike of a missile with three tailfins. The resemblance to SRAM is so close that it is tempting to refer to the Kh-15 as “SRAMski”. Unlike SRAM, however, as with the other large Soviet ASMs, the Kh-15 was designed for both strategic and anti-ship attack. There are three versions: the standard Kh-15 nuclear-armed strategic variant, with inertial guidance only; a conventionally-armed anti-ship variant, the “Kh-15A”, with an active radar terminal seeker; and an antiradar variant, the “Kh-15P”, with a passive radar seeker. An export version of the Kh-15A, the “Kh-15S”, was also built. After launch, the missile climbs to the edge of space and then dives on the target steeply at Mach 5, making it very hard to hit.
Raduga began work on the Kh-15 in the late 1960s and it was accepted for service in the early 1980s. A Tu-22M Backfire bomber can carry six Kh-15s in a revolver launcher in the weapons bay, plus four more under the wings. It is also carried by the Tupolev Tu-160 Blackjack bomber.

FAB-250 or FAB-1500 free fall bombs
The Russian term for general-purpose bomb is fugasnaya aviatsionnaya bomba (FAB) and followed by the bomb’s nominal weight in kilograms. Most Russian iron bombs have circular ring airfoils rather than the fins used by Western types.
In 1962 a new series of streamlined, low-drag bombs was introduced, designed for external carriage by fighter-bomber aircraft rather than in internal bays. They come in only two sizes, 250 kg (550 lb) and 500 kg (1,100 lb). Both bombs have a single nose fuze.
FAB-1500 free fall bombs
Both the 54 and 62 series designs remain in use. The most common of these are the FAB-100, FAB-250, FAB-500, FAB-750, and FAB-1500, roughly corresponding to the U.S. Mark 80 series. These have seen widespread service in Russia, Warsaw Pact nations, and various export countries.
Larger bombs with less streamlined shapes also remained in the Soviet arsenal, primarily for use by heavy bombers. In the Iran–Iraq War, FAB-5000 (5,000 kg/11,000 lb) and FAB-9000 (9,000 kg/20,000 lb) bombs were dropped by Iraqi Air Force Tupolev Tu-22 bombers, generally against large, fixed targets in Iran. In Afghanistan in the 1980s, Soviet Tupolev Tu-16 and Tupolev Tu-22M bombers used massive FAB-1500, FAB-3000 and FAB-9000 bombs to devastating effect during the Panjshir offensives.

The modernized airplanes, according to available intelligence will be armed with the next generation X-32 (Kh-32) missile, which is under development now on the basis of X-22 (Kh-22), with many improvements like the increased range (up to 1000 klm) and speed (up to 5 Mach). This missile is expected to enter service in 2020. Source redstar.gr
X-32 (Kh-32) missile
There is not much information on the Kh-32 but it is rumored to fly at Mach 7 and has a range of over 1,000 km.
The new weapon will be able to rise into the stratosphere to a height of up of 130,000 feet, with a nuclear or conventional 500-kilogram (1,102 lb) warhead and hit targets within a few yards.
Each long-range bomber can carry only two of these cruise missiles, each of which weighs about six tons.
The missile is equipped with an inertial navigation system (an autonomous system not affected by electronic warfare) and heat-seeking warheads with a radar homing head. This solution will greatly improve the accuracy of its guidance, making it independent of GPS/Glonass navigation satellite systems.
Unlike other missiles, the Kh-32 rises into the stratosphere to the height of aerospace probes, where there are no potential adversary fighters or missiles. Then it flies a distance of up to 1,000 kilometers (620 miles) before swooping down on a target.
According to an RBTH source in the defense industry, no Russian or foreign missile defense system today is able to detect the Kh-32 approaching the target: neither the domestic S-400 Triumph system nor the American MIM-104 Patriot.
“The airspeed of the Kh-32 is five times higher than its predecessor, which has been deployed since the late 1960s,” the source said. “Air and missile defense systems today cannot detect a diving warhead, which moves down at a speed of over 5,400 km/h.”

2nd Radio combat (round trip) of a bomber Tu-22M3 loaded with 12,000 kgs of bombs mission profile hi-hi-hi subsonic (cruising at high altitude throughout the flight profile) off from the Iranian airbase Hamadan:
One option would be a configuration 3rd internal load, for example, 27 pumps of 250 kgs. This does not harm the aerodynamics, as if it does load bombs on external-media and provide a radio hi-hi-hi subsonico above the 2nd option.
