JDAM guided weapon kits for Ukraine

Foreign countries continue to supply the Kyiv regime with weapons and draw up new supply plans. Recently it became known that the United States is discussing the possibility of sending JDAM kits to Ukraine, and soon they officially announced the provision of such assistance. It is assumed that thanks to this, the Ukrainian Air Force will have modern guided bombs. However, it is already clear what problems and difficulties such assistance will face.

According to the latest


On December 14, The Washington Post reported on the new plans of the American authorities. It learned from several unnamed senior sources that President Joe Biden's administration is exploring the possibility of providing Ukraine with JDAM (Joint Direct Attack Munition) kits. Thanks to this, the Ukrainian Air Force will receive guided bombs and improve its combat capabilities.

At that time, the decision to ship JDAM products had not yet been made. The President or his security advisers did not approve of such a proposal. Whether they will allow the allocation of such assistance, and when this might happen, WP sources did not specify.

Technical details of possible assistance were also not given. So, WP did not indicate in which complexes the supplied kits can be used - in aviation or ground. In addition, it was not reported in what form the kits could be provided, independently or as part of ready-made adjustable bombs. If the United States allocates only kits, then it is not clear with which Ukrainian ammunition they will be used.

In the context of obtaining and deploying a new weapons The Washington Post recalled the problems of Ukrainian military aviation. It is equipped only with old Soviet-built aircraft, which imposes certain limitations. Over the past time, the Pentagon has been looking for ways to modernize this technique. At the same time, they actually abandoned plans to provide modern foreign aircraft, which require retraining of flight and technical staff.

However, the United States provided NATO-style aviation weapons. Ukraine received and began to use AGM-88 HARM missiles. However, WP notes that HARM and JDAM products differ in terms of operation and guidance.

The American leadership did not comment for several days news about the supply of JDAM. But on December 21, they officially announced a new large military aid package, which, among other things, will include such products. At the same time, the number of products for shipment, delivery features, etc. are not specified.

Modern remedy


The JDAM project has been developed since the early nineties. His goal was to create a new bomb for tactical aviation, capable of hitting targets at any time of the day and in any weather conditions. Several options were considered with different control methods, and in the end, guidance according to the GPS system data, implemented in a joint project of several companies, was chosen as the most successful. Tests of the first experimental bombs of this kind started in 1993.

From a certain time, as part of the JDAM project, it was planned to develop a special kit for installation on an existing unguided bomb. With its help, the latter was supposed to turn into an adjustable means of destruction. JDAM products of this kind appeared by 1997, and subsequently passed all the necessary tests, including military ones.

At the turn of the decade, the JDAM kit made it possible to create several new guided bombs in various calibers. Such weapons entered service with the tactical aviation of the Air Force and the US Navy. Later, foreign orders appeared - in total from more than 30 countries. The Boeing company is engaged in the production of kits and the assembly of bombs with them.

In the XNUMXs, the original JDAM kit was supplemented with a laser homing head. This version of the product, designated as LJDAM, reached the series and was supplied to various customers. Other guidance methods were also worked out, including with the help of a passive radar seeker.

Since the beginning of the 21s, JDAM bombs have been regularly used in various military operations conducted by the United States and other foreign countries. Quite quickly, they became one of the main means of destruction used by tactical aviation. This was facilitated by a favorable combination of performance characteristics, ease of use and relatively low price. So, in recent contracts, the cost of the kit was brought up to 22-XNUMX thousand dollars.

JDAM is a set of tools and instruments for installation on an unguided American-style bomb. A suspension device with weapons control system connectors, as well as small wings, is mounted on the ammunition body. The regular bomb shank with stabilizer is replaced by a new instrument compartment. In the case of the LJDAM modification, a small nose hull with a laser seeker is also used.

The main element of the JDAM kit is the tail hull, which acts as an instrument compartment. It contains satellite navigation devices, an autopilot and steering machines. Outside, x-shaped stabilizers with rudders are installed on the compartment.

The principle of operation of the JDAM bomb is quite simple, and in this respect it does not differ from other, more complex adjustable bombs. Before reset, the automation receives the coordinates of the target from the carrier aircraft. Then the bomb carries out an independent flight, during which the autopilot monitors the trajectory and, if necessary, corrects it. During tests and actual use of bombs with a set of JDAM showed QUO up to 7-10 m.

Based on the available unguided bombs, a whole family of JDAM ammunition of various calibers was created. So, based on the 500-pound free-falling Mk 82, BLU-111 and BLU-126, several versions of the GBU-38 JDAM product were developed. The larger thousand-pound GBU-32 is based on the Mk 83 and BLU-110 hulls. The family's maximum caliber is 2 pounds for the GBU-31 bomb. It includes products Mk 84, BLU-109 and BLU-119.

JDAM products are used by all major US tactical and strategic aircraft. Depending on the carrier's speed and flight altitude, they can hit targets at a distance of up to 25–28 km. The possibility of increasing the range by installing a folding wing was studied.

Integration problems


JDAM kits and air bombs based on them are of obvious interest to the Kyiv regime. He wants to receive modern foreign weapons, including those showing and confirming high performance. Nevertheless, for obvious reasons, he will not be able to use the full potential of American bombs. This will be prevented by various problems along the line of integration of such weapons.

American sources do not say what products will be supplied, but it is already clear that there will be difficulties with the compatibility of components. So, in the case of the transfer of ready-made GBU-31/32/38 bombs, it will be necessary to redo the aircraft beam holders for foreign mountings. If deliveries are limited only to the tail instrument compartments, then a more difficult task will arise. They will have to be connected in some way to the bodies of Soviet-style bombs. Whether it will be possible to do this and not create new problems is unknown.

It should be noted that compatibility with the carrier aircraft is determined not only by the configuration of the holder and its locks. Much more important is instrumentation. Aircraft of the Ukrainian Air Force do not have devices for interacting with JDAM and entering commands. Installing such devices on a Soviet-style aircraft looks like at least a difficult undertaking.

Without such equipment, the bomb's automation will have to be programmed on the ground before departure, which will drastically limit combat capabilities. Because of this, JDAM bombs, even under ideal conditions, can only be used against stationary targets with known and unchanged coordinates in advance. The carrier will not be able to independently find the target, determine its coordinates and deliver an accurate strike.

The combat use of obsolete aircraft with modern bombs is associated with serious risks. The JDAM product is capable of flying no more than 25-28 km, due to which the carrier will fall into the short-range or medium-range air defense system before being dropped. At the same time, he will be detected and taken for escort long before reaching the drop line.

Raises questions and the survivability of JDAM bombs in a modern armed conflict. It is quite possible that Russian air defense is capable of detecting and hitting not only carrier aircraft, but also dropped guided bombs. During the hostilities, the interception of more complex targets has already been demonstrated.

Useful experience


Thus, the receipt of JDAM kits or air bombs with similar equipment will have practically no effect on the real combat capabilities of the Ukrainian Air Force. It will not be possible to realize the potential of such weapons, both for technical reasons and because of the small number of Ukrainian military aviation. In addition, one should take into account the active opposition of the Russian Aerospace Forces and Air Defense.

The Russian army has not yet encountered such a weapon, and its appearance in the combat zone will provide useful experience in dealing with it. In addition, the Pentagon and its contractors will benefit. They will be able to work out the installation of JDAM on foreign-made aircraft, as well as test this weapon in the face of active opposition from anti-aircraft weapons. It will certainly be a useful experience, and Ukrainian planes and pilots are ready to sacrifice for it.

    Well, if HARM was somehow able to be integrated into Ukrainian aircraft, then there will be no problems with JDAMs.

    The JDAM product is capable of flying no more than 25-28 km, due to which the carrier will fall into the short-range or medium-range air defense system before being dropped.
    Even if, when dropped from a pitch-up from an ultra-low altitude, the bomb flies only 10 km, this will dramatically increase the effectiveness of the remnants of Ukrainian aviation.
    And the difficulties with the tails of Soviet bombs are greatly exaggerated, I don’t think that a certain adapter is difficult to manufacture.

      The problem will not only be in the mount. If we hang an American tail on a bomb of a different weight, shape and size, we get an inadequate response of the tracking system to the deviation of the trajectory and a sharp increase in the CEP. Well, why then fence the garden?

        This thing is definitely reprogrammable. And I think that the main difficulty is in ensuring flight balance, which in turn is solved by testing. And the fact that the NATO trash has plenty of both bombs and test aircraft, I think that you will not argue either.

            But these kits are installed on different bombs, which means they are adapted for adaptation - the first. Second - where is the guarantee that such work has not been carried out for a long time? I have already written about the sufficient amount of our equipment and weapons.

    Before this conflict, the Russian army had not met with systems like “himars” and “excalibur” ... what do the headquarters of one of the divisions in full strength and the soft tissues of “space” tell there, how is there a useful counteraction experience? ....

    What nonsense are you talking about! That is, on the lives of our soldiers, they decided to conduct experiments? If we had these weapons, we would know how to deal with them even without experiments. But what am I talking about. We don’t have UAVs, but here is a bomb.

      ZhIDAMs are very dangerous, effective, cheap and massive weapons. While its warheads are an order of magnitude more powerful than the warheads of expensive missiles. Then the scope of the ZhIDAMs, this is the direct support of the assault groups, thanks to the high-precision infantry can order heavy splashes in positions from 100m. The hope for short-range air defense is little clear to me, since aircraft throwing bombs will make a slide and dump, here we need radars with an overlap of 50 km and air defense of the BukM3 type, Tor at least, whose radars, in turn, will fall VSU carriers of HARMs. In addition to ordinary ZhIDAMs, there are also those with wings and an increased range, like up to 70-80 km. The supply of such weapons as ZhIDAMs tells me that the Air Force is being prepared for the Armed Forces of Ukraine. And secondly, judging by the Kremlin’s silence about the ZhIDAMs, although this event is no less important than the possible delivery of A1M2 or Leo2 tanks, when the latter are delivered, there will no longer be any reaction from the Kremlin, well, since the ZhIDAMs are so sluggish.

    Why do we need aircraft carriers?
    There is a good option (in theory) when this bomb is crossed with a rocket booster from HIMARS, but of the previous generation with a cluster filling and launched from special cradles that can be placed on a large number of ground-based carriers. The declared output height is approximately 8-10 km, then the accelerator is separated and the bomb itself begins to plan towards the target. The article talks about the ranges that are specific for planning ammunition, i.e. over 50 km. True, it says about a modification with a wing module / And there are about 14000 such ammunition in the states. A great opportunity to dispose of it for other people's money.

    I remember here in the comments it was stated that HARM missiles could not be integrated into Soviet aircraft. Many “new” NATO members from Eastern Europe kept Soviet aircraft and, apparently, for 25 years they have been solving the issues of compatibility and integration of weapons, so the author, once again ending the article with his standard head-butting organizational conclusion “that this is all garbage”, was clearly in a hurry .

    And who said that the Ukrainians will strike at moving targets? In our country, "stationary, with coordinates known in advance" - a dime a dozen: airfields (both military and civilian), oil refineries, and just multi-storey residential buildings and office buildings. And the fact that Ukrainian pilots will become a kind of kamikaze is generally of little interest to anyone. In Ukraine, they will simply become national martyr heroes.
    How will they fly to the territory of Russia? - ask. Yes, it's easy and not forced. Just like we flew to the Belgorod region more than once. Both helicopters and planes. They flew across the border, were bombed and back to their Ukraine. They were shot down only on the way back. So, some suburbs may become the next target of banderlogs.
