Magnificent seven

In October, the 1961 of the 642-th Guards Aviation Regiment of fighter-bombers of the Odessa Military District (Martynovka airfield in the Mykolaiv region) ended with military tests of the Su-7B aircraft created at the Pavel Sukhoi Design Bureau.

The supersonic (maximum speed - 2150 – 2200 km / h) fighter-bomber, developed on the basis of the not widely spread front-line fighter Su-7 (without a letter after the number), was officially adopted at the beginning of the year. The rush was probably explained by the fact that the Soviet Air Force desperately needed a machine designed to replace the “erzatsy” used in this capacity - the MiG-15bis and MiG-17F subsonic fighters.

Su-7B in various versions for a very long time became the main strike complex of the domestic front-line aviationimmediately displacing the "classmate" - the supersonic bomber Yak-28, not to mention the outdated IL-28. By 1965, there were 450 Su-7Bs in the combat structure of the USSR Air Force, about 28 were built in Yak-350s in bombing and strike versions. In total, Su-7B, Su-7BM, Su-7BMK and Su-7BKL fighters were built pieces. Plus 1342 training "sparks" Su-365U.

New "drying" and the Yak were considered primarily as carriers of tactical nuclear weapons. Su-7B was equipped with an 8UX69 (“244H”) compact special bombs placed on the external suspension, 5 kilotons in weight and kilograms weighing about 500, and Yak-28 (like IL-28) - much heavier (1200 kg) and requiring an external heating box (much less heavier (30 kg) and requiring an external heating box (like X-NNUMX) - much more heavy (4 kg) and requiring an external heating box (XNUMX kg) and requiring an outer heating box that requires an external heating box that is much heavier (XNUMX kg) and requires an external heating box that requires a warm outer cover (XNUMX kg) and requiring an external heating box that uses an external heating box that is using a XNUMXB). -kiloton RDS-XNUMX on the interbody fuselage.

For the use of nuclear weapons, the Su-7B was equipped with an electromechanical device for bombing from a PBC-1 cabriroon, which automatically determined the reset time provided for at a speed of 1000 – 1050 kilometers per hour when maneuvering with a sharp climb from small to 3500 – 4000 meters. Su-7B involved in the ground tests of aviation nuclear weapons.

Magnificent sevenSubsequently, the nuclear arsenal of the Su-7B was replenished with the RN-24 special bombs and, finally, the RN-28, miniaturized to the mass of 250 kilograms. However, the arsenal was not limited to nuclear weapons: in addition to the two built-in 30-mm guns of the HP-30 "universal" caliber, optimized to destroy both airborne and ground targets, including lightly armored ones, the "drying" carried a fairly diverse conventional outboard armament. Its options for an improved version of the Su-7BLK with a wheel-ski chassis and increased to six (against the previous four) number of suspension points included 160 57-mm unguided C-5 missiles in four 32- and two 16-charging units, 42 134-mm NUR C-3K in six seven-shot launch consoles, six heavy 240-mm NUR C-24, four 500-kilogram and two 250-kilogram bombs or six 100 – 250-kilogram, napalm tanks, etc. According to foreign sources, Su-7B fighters could arm and guided missiles class "Air-to-air" P-3S infrared homing head. Toward the end of their career Su-7B received suspended electronic warfare stations.

Simple in design, but not the easiest in piloting, the Su-7B won among the Air Force personnel jokes like “Tail and wings on a pipe - this is“ drying ”- the family and“ be ”. Although for the sake of truth, it must be said that the “winged tubes” were both the MiG-21, and the Su-9, and the Su-11. Foreign experts gave Su-7B different ratings. For example, American Lon Nordin, the author of Air Warfare in the Missile Age (“Air War in the Rocket Age”) noted: “Su-7B was developed as a means of delivery of a tactical nuclear weapon at supersonic speeds and therefore had a modest combat radius at maximum load ammunition. The maximum combat payload mass (2000 – 2500 kg) in the latter case was lower than that of a number of Western tactical fighters of the time. So, significantly lighter than the Su-7B and its modifications, the American F-5A Freedom Fighter lifted 2812 kilograms of missile and bomb load, surpassing even improved models of "drying" by 312 kilograms. But the enemy aircraft significantly lost to ours at maximum speed at high altitude - more than 600 – 700 kilometers per hour, although for fighter-bomber this is not so significant.

Serious drawbacks of the Su-7B were, perhaps, its lack of fitness and the impossibility of effective combat use at night.

However, many Western experts invariably emphasized the strength of the Su-7B design, its reliability and good tactical performance at low altitudes. Plus a relatively low cost - this played a role when the Su-7B entered the international market of military aircraft quite successfully (of course, some states, rated by Moscow as sympathizers, received these planes on extremely favorable terms or taking into account the subsequent debt write-off).

As a result of use in local wars, the Su-7B became a real "front-line soldier". It was used in the hostilities of the Air Force of Egypt, Syria, Iraq, Algeria, India and Afghanistan. In these countries, as well as in Vietnam, the DPRK and South Yemen, it was delivered in the commercial version of the Su-7BMK, which lacked equipment that allowed the machine to be used as a carrier of nuclear bombs. But the pilots of the Polish and Czechoslovak People’s Army at their Su-7BM and Su-7BCL knew what to do in the case of the third world war. I had in mind the possibility of transferring tactical nuclear weapons to the Warsaw Pact countries under Soviet control (for more details, the “Nuclear Brotherhood”). Su-7B also the Air Force of Romania and Hungary, but it was not known whether they were intended for use in a particularly shock version.

Having passed the service baton to his deep modification with the variable sweep of the Su-17 wing (this family also includes the export Su-20 and Su-22), the veteran Su-7B remained - already of course, in a smaller number - in the combat formation of the USSR Air Force to 1989 of the year, a little before the collapse of the Soviet Union. It was certainly a staging machine that left a bright mark on stories domestic aviation.

    Against the background of Migov, the SU-7 impressed with its size. He possessed an original beauty and elegance that immediately sank into the souls of both pilots and schoolchildren. In this connection, the first ones always remembered about '7' with warmth, the last ones wiped living specimens with their pants near the District officers' houses (I was among them). Moreover, it was necessary to climb onto this "colossus".

      I traveled around Afghanistan quite a bit (Andropov times) and noticed that the Su-7b were mostly with the Afghan flags, and ours flew the MiG-21.
      Regarding “The tail and wings on the pipe are“ drying ”- seven and“ no ”:
      if you look into the nozzle of the drying engine, then the turbine blades are seen, tentatively, in the area of ​​the wings. That is, the afterburner tube occupies, somewhere, a third of the plane.

        Su-7 was also not with variable sweep. It appeared on the Su-17.
        He didn’t serve them, but even before the school he worked at the ARZ where they were being repaired. Like everything with the Sukhoi Design Bureau of that time, it was striking that the design was so reasonable with such a small size. And also its survivability in very difficult situations.

      The MiG-23 is a front-line fighter, and the MiG-25 was developed as an interceptor, for them the main target was enemy aircraft, the Su7b fighter-bomber could have targets on the ground.

      initially it was not planned to put guns on the MiG-23, but the situation changed and the 23 received a Gatling six-barrel GSh-6-30 30mm caliber, it was not planned to install side artillery on the MiG-25 either, but within a certain series a batch of Foxes with GShs was released -6-23, because the GSh-6-30 "strained" the glider at the speeds of three sounds, however, on the MiG-31 GSh-6-30 is installed normally

    Good article. True, I found them already as teaching aids. Mostly disassembled, with partially removed casing (for clarity). But the comparison with the F-5 is not entirely correct. The Su-7 was more often compared to the F-105 fighter-bomber. And the F-5 with the MiG-21. And thanks to the author, I did not imagine that the "vigorous" bomb was squeezed into 250 kg.

    At the very beginning of the 60s, a serial fighter-bomber, a carrier of nuclear weapons with a speed of Mach 2, is such a high-tech that 2-3 more countries could repeat, the rest of the "developed" European countries could not even dream of this.

      And what have the screams? and where did you get the idea that I condemn him ... It's just a constant ... For starters, I know this machine for a start ... at one time they prepared for it in my school of technicians and on the technology course we had it ... The device is really "ersatz" when "I blinded it from what it was" ... They took an engine (good powerful but very large) and tried to make an airplane on its basis ... They did ... (illustration of an unpretentious thesis that with a good engine and the fence will take off) but almost did not think about operation ... As a result, we got an "intermediate machine" which after a while was brought to mind by creating a really good IS with a variable geometry Su17 ... And the "seven" ... well, it remained a topic for jokes and swearing for the technical staff ... So what's in my stupid remark? I didn’t come up with the joke about the "pipe" ...

    I heard this joke for a long time. A joke is a joke. I also like to joke. But you are serious about ersatz. Maybe I don't understand what, but "ersatz airplane" literally means that this is not an airplane at all, but its substitute. I do not understand how this can be said about the device, which had record performance at that time. Erzats and record, sorry, but these are more antonyms, not synonyms. I understand that the device, apparently, was damp, as, indeed, many devices of that time, since it was the heir to the very wrecked Su-7 and since the arms race is a race.

      Because it was a "substitute" ... like many cars of that time ... for a number of reasons, and due to the lack of time for fine-tuning and due to a lack of understanding of the actual tasks ... And simply because And the same Yak 28 was never adopted for service (also ugrebishche still then) but at the same time it was built in a rather large series and was in the regiments. This is not bad and it was not good ... To treat these machines as full-fledged, forgive me as a techie, I cannot. But I understand why I often had to do a lot according to a "temporary scheme" (by the way, there is nothing more permanent than temporary, like the same residential barracks) ... Therefore, I do not blame, but rather I remember ...

        This is because Russians still translate the American term maitainability to mean maintainability.
        In fairness, it should be said that the Sukhovites on the third generation Su-24 and Su-17 machines tried to somehow change the unsightly situevina. But even, when you compare the diameter of pneumatics and the height of "domestic" products with those of the US, you understand that the Russians do not study the requirements of the US Department of Defense guidelines with regard to this very maitainability.

    And here I am criticizing the article. If we start the article with the fact that the tests were completed in the Odessa region, then you need to write something interesting about them - how they tested, what difficulties were, what results they achieved. The article itself has a lot of nuclear bombs, but there are no features of the machine itself — landing behavior or the difficulty of flying, with a corkscrew as it was, is missing at least a couple of memories of the pilots flying on it. The Su-7B gun was needed more for combat with airplanes; getting from this aircraft into an armored troop-carrier on the battlefield is very doubtful that the pilot would see it at all, while the tactics of bombing and firing squadrons at NURs in the areas were used. At the same time, I somehow read that bombing was practiced using the top-mast method, and on land. The tester at least got into the hangar.
