The Grom missile and bomb weapons system and its carriers


In 2015, Tactical Missile Weapons Corporation (KTRV) for the first time presented materials on the Kh-36/9-A-7759 / Thunder, a promising guided missile and bomb weapon system. Over the past years, the complex has passed all stages of development and testing, as a result of which it is ready for adoption. New aviation weapons of destruction (ASA) are intended for all major domestic combat aircraft, as well as for UAVs.

For manned aircraft

Since the first demonstration of promising TSAs, regular reports have appeared about possible carriers of such products. It was claimed that they could be used by all the main domestic tactical combat aircraft, up to promising fifth-generation fighters. More details appeared later.

In June 2018, a presentation was presented in free access, describing the main features of the Thunder project and the progress of ongoing work. Among other interesting materials, it contained photographs of 9-A-7759 products on carrier aircraft.

The first picture depicted a Su-34 front-line bomber with a whole set of promising ASPs. Two bombs (missiles) were under the planes and two more products were suspended under the fuselage. Each of them occupied one beam holder. The second photo showed the possibility of using the "Thunder" as part of the arms of the MiG-35 fighter. In this case, the product 9-A-7759 was located on the AKU-58U device.

In early August 2019, KTRV announced the completion of tests of new ASPs and its readiness for deliveries to foreign customers. In these reports, another potential Thunder carrier was mentioned, characterized by its characteristic features. So, missiles and bombs of new models can be carried by a Su-57 fighter - including on an internal suspension.

Thus, the 9-A-7759 Grom products are compatible with all major tactical aircraft of the Russian aerospace forces. Such TSA can be used by fighters and front-line bombers of modern and new models, which significantly expands their combat capabilities.

Unmanned vehicles

Over the past few years, our industry has been developing unmanned aerial vehicles for attack purposes, capable of carrying one or another weapon to destroy ground targets. Recently it became known that the “Thunder” complex will contribute to the development of this area and will also become weapons new UAVs.

Such news On February 27, Izvestia was published, referring to its sources in the defense industry. It is alleged that a fundamental decision has already been made to equip attack UAVs with systems of the Grom family, which will allow attacking ground targets with high accuracy and efficiency. As carriers of such ASP are considered Drones S-70 "Hunter" and "Altius".

Part of the work in the new direction has already been completed. It is reported that Thunder has been tested with the Hunter UAV. An experienced drone successfully coped with the removal of large-size mock-ups of bombs (missiles) and performed their reset. How soon the entire process of integration of new weapons will be completed is not specified.

Work on the introduction of products 9-A-7759 in the ammunition list of Altius UAVs has not yet been completed. KTRV conducted an assessment of such opportunities at the beginning of 2018, but in the future, work slowed down. For a number of reasons, the Altius project has moved from one development organization to another, which has led to some difficulties. All these events led to a temporary suspension of work on the implementation of the Thunder. However, now the development of "Altius" continues, and the same applies to new weapons for him.

Thus, in the foreseeable future, two promising heavy UAVs with shock capabilities capable of carrying products from the Kh-36/9-A-7759 complex can enter service immediately. Thanks to this, the VKS will receive all the advantages inherent in unmanned vehicles and modern controlled TSA.

Shock family

The Thunder project offers aviation weapons of various classes, built on a modular basis. Due to this, bombs or missiles with different characteristics can be assembled from common components. The project makes extensive use of finished components. One of the main sources of units was the X-38 air-to-ground guided missile.

A product of the 9-A-7759 family is assembled from several units. This is the module of the main warhead (MBCho); an optional MBChd module is optionally used. Designed by so-called propulsion module module MDU. There are also planning and control modules (MPU) and a module of steering drives of MCI. The combination of four modules with one or another equipment gives a bomb or missile. Three variants of such TSA with different features have been developed.

Product 9-A-7759 "Thunder-1" ("Thunder-E1") is a guided missile. She receives MBCho type 9-Zh1-7759 (high-explosive fragmentation, weight 315 kg) and carries 161-kg MDL. The MPU and MPP modules are equipped with a wing and rudders folding in flight. Aiming at a target with known coordinates is carried out through a satellite navigation system. The 4,2 m long and 594 kg rocket has an average speed of 300 m / s and is capable of flying at a range of up to 120 km.

Product "Thunder-2" or 9-A1-7759 is a guided planning bomb. It is generally similar to the Thunder-1 missile, but differs in the absence of an MDM. Instead of a motor module, an MBChd with a mass of 165 kg is installed. Guided bomb "Thunder-2" can be used for targets at a distance of 60-65 km. A maneuver is possible for hitting an object in the rear hemisphere of the carrier.

The second version of the bomb, 9-A2-7759, is equipped with two warhead modules of the 9-Zh2-7759 type with volume-detonating equipment. MBCHo has a mass of 250 kg, MBChd - 120 kg. The total mass of the product is reduced to 488 kg while maintaining other parameters. Range of application - 65 km.

Products of the Thunder family have serious advantages over a number of existing samples. First of all, it should be noted the power of the warhead modules. According to KTRV, the combat effectiveness of the Thunder-1 is 80% higher than that of the OFAB-250-270 air bomb. The Grom-2 bomb with two MBCH is 50% more effective than the OFAB-500U product. 9-A2-7759 volume-detonating ammunition is twice as powerful as the KAB-500OD bomb.

Also, the Grom complex compares favorably with other ASPs with a discharge / flight range. From this point of view, the 9-A-7759 family surpasses most modern models of domestic development. The satellite guidance system provides a CVO of not more than a few meters, which also meets current requirements.

Weapons with the declared characteristics can be used to destroy a variety of ground targets with known coordinates, from manpower to fortified objects. The “Thunder” family is able to supplement existing TSAs in solving certain problems, and in other situations it can completely replace them, realizing its advantages.

Weapons for the future

Last year, KTRV announced the completion of major work on the 9-A-7759 Thunder project and its readiness to supply serial products to customers. Bombs and missiles of new types are ready for use in the aerospace forces and the use of various types of combat aircraft. At the same time, development work is ongoing to integrate such ASAs into the armament complex of promising UAVs.

Apparently, these processes will be completed in the next few years - probably simultaneously with the adoption of drones in service. Thus, in the foreseeable future, the Russian air force will be able to get all the required weapons systems with high performance and wide capabilities.

However, the future of the ASP family “Thunder” is still unknown. Reported completion of the tests, but information on the adoption of such weapons in the arsenal of the Russian Aerospace Forces has not yet arrived. In addition, well-known messages featured only a willingness to export - but not to the supply of their army. However, the latest news provide reasons for optimism. The Ministry of Defense decided to equip promising UAVs with Thunder, and with them manned aircraft of all major types can also receive such weapons.

        Typical "clucking" of the urya-skakuas, sitting on the neck of the people. I am already crying for everything out of my pocket, and judging by the fact that the levies are growing, the "police state" after the implementation of the "national property" even has no money left for you and you. You know, and I am not against the taxes and fees paid by me went to the purchase of really modern weapons, and not to feed, for example, packs of "policemen" and Internet trolls "on a salary." If so, your gang will have to move the retirement age to nowhere, beyond "handing over plastic wreaths" and "reading obituaries". Tear off the worn sweatpants from the sofa and go waving a broom, in the literal sense, of course, and not as you are used to, on the street, because you are not good for anything else. At the same time, you will wake the residents up in the "sponsored" neighborhood with your sonorous "kukuryak". I am absolutely not interested in you, because instead of words on the topic, you always try to shake the air with "emptiness". stop

      I agree, we have a strange approach. Both JDAM and Spice turn a "dumb" bomb into a "smart" one for a relatively low cost. Moreover, ordinary cast iron in warehouses is in store for three wars.
      So, to create a new product is a much more monetary (and, accordingly, pleasant) enterprise than to equip ready-made bombs with guidance and planning systems.

        Aiming navigation system "Hephaestus" miraculously sends a conventional free-falling ammunition with a minimum efficiency. Without having to spend tens of thousands on each disc. And here is a universal constructor. There are a bunch of similar blocks at the plant. What the customer needs, then they will collect.

              Look at Israeli SPICE (Smart, Precise Impact, Cost-Effective - intelligent, accurate exposure, economical). In fact, these are sets for ordinary cast iron, incl. concrete bombs, corresponding mass.
              Spice-250 - 113 kg (250 lb) bomb, planning range up to 100 km
              Spice-1000 - 454-kg (1000-lb) bomb (Mk. 83, RAP-1000 and the like), planning range up to 100 km
              Spice-2000 - 907 kg (2000 lb) bomb (MK 84, RAP-2000, BLU-109 and the like), planning range up to 60 km

              In the pictures: Spice bombs. Light gray are parts of the control and guidance kit, olive is a free-falling bomb (Mk83 and Mk84)

              In addition to bombs, control and guidance modules are placed on the NAR, incl. small caliber (70 mm Hydra). With minimal refinement, turning rockets into adjustable ones.

                  naturally, such ranges are achieved only when dropped from a high altitude (more than 10 km) and at a decent carrier speed

      So one does not interfere with the other. Specifically, this team is developing a new weapon compatible with UAVs and internal compartments of the Su-57. The matter is also necessary.

      It would be nice, of course, someone else was engaged in "controlled" gadgets for conventional bombs, but not yet heard. I admit that the export potential of such products is lower than that of new weapons, so this direction is not so interesting for KTRV.

In general, as the song says: "Don't talk about love! Everything is said about it! ...". But here's what I'm talking about ...! Why am I so naive? That's how many times I've come across trusting disinformation, and it's not enough! As a rule, a message appears like: KB Mitkino has developed a terribly dangerous bomb (rocket), which itself finds the "barmaley", pursues them, catches them in an open field, puts them against the wall and shoots them 3 times! The bomb is being successfully tested and will soon be produced and sold; because. many military men (both ours and not ours ...) showed baaal interest and desire! After that, time passes ... (years 2,3,5! ...), "posters" fade and disappear somewhere ... First, I am in joyful anticipation that soon we will see pictures and videos of bombers taking off, loaded "terrible" bombs ... then I worry a little: they say, where is the promised? ... then I forget ...! And suddenly...! Again....! After 5 years! ... "The Mitkino Design Bureau again offers that very terrible bomb that catches the" barmaleevs "in an open field, puts them against the wall and shoots them 2 times ... because they shot them once during the previous tests ... recourse

    "The 9-A2-7759 volumetric detonating ammunition is twice as powerful as the KAB-500OD bomb."

    The very main question of the amateur. Why are the main and additional units not unified? Or I didn’t understand something. And then honestly looks like a creation of a gloomy genius. Plus, it is advisable to provide for the discharge of an additional charge. Increase flexibility. For example, the shed with terrorists destroys the main charge, and the dumped in advance dopbch, in a few seconds after the explosion, falls asleep with the land of mines to complicate rescue operations.

    Weapons for the future

    Do not forget that a relatively inexpensive weapon with guidance systems on external target designation is not suitable for war with high-tech opponents. Such systems cannot act on moving targets.
    Satellite navigation channels can be locally suppressed by relatively inexpensive electronic warfare equipment.

    The IHGS WGC increase the cost of products but also require much more advanced counteraction systems.
    ISN (inertial guidance system) - autonomous.

    The next stage is the development of universal modules that can give the system the functions of hitting moving targets.

      There is no information about the homing head in the article, only the photo shows a caption about the television version, which, of course, is capable of aiming at moving targets. In addition, there is a head with a laser lidar, and I admit that there is a combined head in which a thermal imager, lidar, and teleprocessing, and the ability to aim at a fixed portrait of the radiation of the target are integrated.

      I agree. The Papuans can also be attached with an ordinary bomb, and if there is an air defense, then it will drop such a bomb without problems (the target is high-altitude, slow, with a large EPR (otherwise it will not be good to plan) - the anti-aircraft guner's dream). And GPS guidance is a corrupting influence of the states: for a big war, you have to make an inertial head or already in an adult way, with recognition of the terrain.

        A huge plus of modularity is precisely in the fact that if necessary, you can do what you need. You will need a combination and they will do it. Even I think after working out in the existing configuration, they will immediately begin to expand the range of heads and warheads.

    Great idea with modularity. But two points were wary - satellite navigation is good only in a war with barmales, in a serious mess, as for me, it simply will not exist or will be in a very limited time, and axisymmetric cases of products. Is it possible that round casing cross-sections fit better into the Su-57 compartment?
