Deliveries of the latest American cruise missiles do not determine the course of military operations in Ukraine

By Anthony Bell

At the end of September, the United States announced a new package of military aid to Ukraine. The only new item that was missing from the previous packages was the AGM-154 JSOW (joint stand-off weapon). American authorities hope that this weapon will allow Ukrainian aviation to operate more effectively at the front. However, it is already becoming obvious that imported bombs will not affect the situation in Kyiv.

In recent months, the press and the expert community have actively discussed the possibility of supplying new weapons to Ukraine. Opponents have spoken out that the United States could supply Kyiv with long-range AGM-158 JASSMs (joint air-to-surface standoff missiles).

However, in the twenties of September, foreign media reported that the delivery of this missile, at least in the near future, is not planned. Instead, Washington is going to transfer AGM-154 JSOWs to the Ukrainian Air Force. However, this information was obtained from unnamed sources, and its reliability was questionable.

Soon these reports were confirmed. On September 25, the White House proposed a new package of military aid to Ukraine as part of the so-called regulation of the powers of the president. This is the 66th package since 2021 and the 12th in the current year. The document provides for the transfer of medical damage worth a total of US$ 375 million.

The main goal of this package is to replenish Ukrainian arsenals. It includes new batches of artillery world ammunition, various missiles and other types of ammunition. In addition, the list of deliveries includes some air-to-surface munitions with cluster equipment. Their type was not named openly, but the American media immediately wrote that these were AGM-154 JSOWs.

As always, the American side did not disclose all the details of the planned international deliveries to Ukraine. In particular, it is unknown how many bombs will be transferred, where they will be taken, when the delivery will begin, etc. Given the experience of previous military aid packages, it can be assumed that the bombs will be sent in the near future. It is quite possible that the first batch of these products was prepared for shipment at the same time as the documents were being drawn up.

The production of the AGM-154 bomb was completed several years ago. It is unlikely that the United States will share the latest series of products with Ukraine. Most likely, Kyiv will be given the first modification and early release bombs, perhaps this is already associated with writing and disposal. This method allows for faster delivery of the process, but limits its volumes and may lead to other problems.

Thus, it can be expected that the Ukrainian Air Force will soon receive new American bombs and will soon try to use them.

However, it can already be assumed that the JSOW products will not live up to the expectations of the Ukrainian side.

The development of a promising guided bomb for tactical aviation under the designation Joint Standoff Weapon began in the late eighties. The new project was handled by the military department of Texas Instrument, which in 1999 became part of Raytheon.

Flight tests of the experimental AGM-154A bombs began in 1991. The project was highly complex and new, which affected the timing of its implementation. Because of this, the Air Force and Navy accepted the new bomb into service only in 1998-1999 and then ordered its serial production.

During the same period, work began on two modifications of the JSOW bomb. Products with the letters “B” and “C” were to receive new warheads and other devices. Despite all efforts, in 2005 both customers refused the AGM-154B bomb, and the AGM-154C entered service only with naval aviation.

Production of JSOW bombs for the US Air Force continued until 2005, and the Navy ordered them until the mid-2010s. In addition, the AGM-154 was able to find buyers outside the United States. Its serial versions were delivered to 13 countries, and Ukraine is soon to become the next foreign recipient.

Combat use of AGM-154A bombs began in 1998 as part of Operation Desert Fox. Cluster-filled munitions were used against Iraqi targets. Later, versions “A” and “C” of the munitions were repeatedly used in other operations and successfully hit various targets.

The AGM-154 JSOW is a guided air bomb designed to destroy remote enemy targets with pre-determined coordinates. It is proposed to use it to disable troops in positions, headquarters, various systems and weapons complexes, etc.

The bomb has a streamlined body of a characteristic shape that reduces its radar signature. The length of the product is 4.1 m, the cross-section of the body is about 330 mm. A high-mounted folding swept wing with a span of 2.7 m is attached to the central part of the body. Stabilizers and rudders are installed in the tail section. The weight of the bomb depends on its modification and does not exceed 495-500 kg.

The basic modification of the AGM-154A bomb is equipped with a control system based on satellite and inertial navigation. It can only attack targets with known coordinates, which are entered into memory before launch. Retargeting in flight is not provided.

The AGM-154C modification retained the autopilot and navigation systems, and also received an infrared homing head. At the final stage of the trajectory, the munition can be guided to a specific contrast target. This makes it possible to work on moving targets.

The basic modification of the JSOW bomb contains 145 combined-action BLU-97/B submunitions. This product is a small cumulative charge with a fragmentation jacket and incendiary elements. Such submunitions are designed to simultaneously destroy armored vehicles, unprotected vehicles and manpower.

The JSOW-C carries a tandem penetrating high-explosive warhead of the BROACH type. It has two charges with a total weight of 225 kg, one of which must penetrate the target’s protection, and the second must detonate inside. Such a bomb is designed to combat field fortifications and other protected objects.

Despite the differences in equipment and weight, both versions of the JSOW bomb have the same flight characteristics. When dropped from a low altitude, the gliding range does not exceed 20-22 km. High-altitude drop allows the bomb to be sent to a distance of up to 120-130 km.

Both serial modifications of the AGM-154 are compatible with all tactical and strategic aircraft of the US Air Force and Navy. In addition, there is a fundamental possibility of using other carriers. In particular, it can be expected that the missiles transferred to Ukraine will be used by Soviet-made Su-24 bombers.

Obviously, the Ukrainian Air Force, having received the AGM-154 bombs, will immediately try to use them. They will try to attack our rear facilities or populated areas in new regions. The Russian army will now have to deal with such a threat. However, it is already ready for such challenges.

From the point of view of air defense, the AGM-154A bomb is a small-sized subsonic aerodynamic target with reduced radar visibility. In this regard, it is similar to a number of other air weapons previously supplied to Ukraine from third countries.

Russian air defense has repeatedly demonstrated its ability to detect and shoot down any missiles and bombs used by enemy aircraft. Radar stations successfully and promptly detect flying targets, and missile systems successfully destroy them. Stealth missiles such as Storm Shadow and small bombs such as GBU-39/B SDB are intercepted.

It can be expected that intercepting the American AGM-154 gliding bomb will not be a difficult task for Russian air defense systems either. It will be successfully solved using existing means and systems.

In addition, it should be taken into account that bombers using such bombs or missiles can themselves be hit by anti-aircraft systems. Russian air defense has repeatedly intercepted enemy aircraft even before reaching the limits of use of missiles and bombs. In the case of JSOW, this situation will be repeated.

However, even a successful interception and destruction of the bomb can have negative consequences. The AGM-154A is equipped with a cluster warhead containing 145 submunitions. Not all of these submunitions can be destroyed along with the missile in the air. Some of them will fall to the ground and add work for the sappers.

Thus, in the situation with the AGM-154A bombs, a scenario familiar from previous events is being repeated. As before, the United States is providing Ukraine with a limited amount of not the most modern weapons as aid. Now we can expect that attempts will be made to use them, but they will not lead to the desired result.

Obviously, the new supply of aviation weapons will not be able to change the situation at the front. Moreover, it creates a threat to Ukraine’s aviation fleet, which in the long term may accelerate the defeat of Ukrainian formations. What is the point of such aid is a big question.
