Sans aide, la défense antiaérienne ukrainienne ne pourra plus repousser que "quelques" attaques massives



Le tableau de chasse de la défense antiaérienne mobile ukrainienne va-t-il continuer de s'étoffer? Certains Ukrainiens commencent à en douter.

A en croire des officiers ukrainiens cités par l'AFP, leurs unités ne disposent plus de munitions que pour faire face à "quelques" nouvelles frappes russes de grande ampleur.

"Dans la situation actuelle, en ce qui concerne les systèmes mobiles de défense antiaérienne, les munitions (...) sont suffisantes pour résister aux prochaines puissantes attaques", a reconnu le général Serguiï Naïev, le commandant des forces conjointes ukrainiennes, interrogé mercredi par l'AFP. "Mais à moyen et long termes, nous avons bien sûr besoin de l'aide des pays occidentaux pour reconstituer le stock de missiles", ajoute celui qui a sous sa charge les unités chargées notamment de défendre le ciel de la capitale. Pour lui, la priorité est donc d'"obtenir davantage de munitions" face à une armée russe qui "veut vraiment épuiser le système de défense antiaérienne" et qui a commencé à recourir à de nouvelles tactiques ces derniers temps, tirant des missiles qui libèrent des leurres, comme ceux des avions ou des hélicoptères.

Selon le président Volodymyr Zelensky, la Russie a envoyé près de 300 missiles et plus de 200 drones explosifs Shahed dans deux attaques, le 29 décembre et dans la nuit du 1er au 2 janvier, des raids qui ont provoqué la mort d'une cinquantaine de personnes.

Selon le général australien Mick Ryan, chercheur associé au CSIS (Center for strategic and international studies), l'objectif du Kremlin est de "tester" la défense antiaérienne ukrainienne, qui est montée en puissance grâce au système américain Patriot ou encore à son équivalent franco-italien SAMP/T MAMBA. Moscou cherche à engager une course contre la montre en espérant que "l'Ukraine sera à court d'intercepteurs avant que la Russie ne soit à court de missiles et de drones".

Military briefing: Russia has the upper hand in electronic warfare with Ukraine
7 - 8 minutes

Russia’s record number of aerial attacks on Ukraine over the New Year period has highlighted Kyiv’s struggle to bolster its electronic warfare technology aimed at jamming and diverting enemy drones and guided missiles.

Both sides have invested heavily in systems that can neutralise each other’s drone armies, but Moscow maintains the upper hand as it had already focused on these capabilities before launching its full-scale invasion of Ukraine nearly two years ago.

Ukrainian forces are however trying to catch up.

Mykola Kolesnyk, commander of a Ukrainian drone unit, said electronic warfare (EW) duels with the Russian forces were fierce and relentless. He described them as “invisible scissors that cut off the connection . . . of a device that is remotely controlled”.

Ukraine and Russia are both using tens of thousands of drones a month. Both have this year increasingly turned to cheap, commercially available first-person view drones controlled by operators using a head-mounted camera.

“The Russians have been producing so many lately that it’s becoming a huge threat,” said Col Ivan Pavlenko, chief of EW and cyber warfare at Ukraine’s general staff. “What’s happening here, the massive use of drones, is new . . . So EW becomes increasingly important.”

Pavlenko called on allies to deliver more capabilities that can “suppress or spoof” the satellite guidance system (GNSS) of Russia’s guided missiles and drones.

“Delivery to Ukraine of a sufficient number of powerful GNSS jammers or at least signal amplifiers could also help counteract enemy air attacks.”

Also, with Russia’s EW systems requiring high-tech components such as amplifiers, synthesisers and software, it was important for western allies to impose sanctions on those components, he said.

The ubiquity of drones on the battlefield is one reason why Ukraine’s long-awaited counteroffensive this year failed to make any significant territorial gains and why the land war is now largely static. Any grouping of tanks or armoured vehicles can be spotted and destroyed within minutes.

Russia has increasingly deployed EW to push off-course Ukraine’s western-supplied, precision-guided munitions, such as Himars rockets and Excalibur artillery shells. Moscow has also used its EW capabilities to mimic missile and drone launches in order to confuse Ukraine’s air defences and identify their locations, Pavlenko said.

Without EW protection, Ukrainian troops are easy prey for drone-guided artillery strikes, drones dropping bombs and kamikaze strikes by exploding unmanned aerial vehicles.

One Ukrainian soldier bemoaned the lack of EW protection for his unit, which was largely wiped out during weeks of intense bombardment on the eastern front, with Russian drones “hitting us like mosquitoes”.

“What radio-electronic warfare? . . . We had none. I don’t even want to recall those days in the trenches. Our boys were falling like flies,” he added.

Gen Valeriy Zaluzhny, commander-in chief of Ukraine’s armed forces, warned in November that EW was “the key to victory in the drone war” — and in breaking the deadlock along the frontline.

“We also need more access to electronic intelligence from our allies, including data from assets that collect signals intelligence, and expanded production lines for our anti-drone EW systems within Ukraine and abroad,” he wrote in The Economist.

EW systems come in many shapes and sizes, from radar arrays and truck-mounted transmitter-receivers to pocket-sized devices. Both sides have rushed to protect troops by erecting makeshift EW systems, which one Ukrainian engineer said volunteers assemble in garages.

Both Russia and Ukraine have maintained strong R&D schools for EW that had been established in Soviet times, but the Russian government has invested heavily in new kit for more than a decade.

“Electronic warfare is an exceedingly important part of modern operations, and the Russians have had a significant advantage in it throughout the war, which has proved a sustained problem for Ukraine,” said Jack Watling, a senior fellow at the Royal United Services Institute, a UK think-tank.

Russia’s Pole-21 guidance suppression system can be stationed on the ground, on towers or mounted on vehicles and can jam an area of 150km, according to a military consultancy report shared with the Financial Times. Another is the Murmansk, which uses vast extendable 32m antenna towers mounted on mobile armoured vehicles.

“The problem is that the Russians are able to field electronic warfare systems across most of the front, down to platoon level in some cases when you’re talking about things like Pole-21,” Watling said.

Still, Ukraine has periodically found weak spots in Russia’s EW and air defences, allowing its drones to strike deep into Russian territory to hit air bases, depots and other targets including the Kremlin itself.

Before it launched long-range missile strikes on Russia’s Black Sea fleet in Sevastopol earlier this year, Ukrainian commandos on speed boats disabled Russian EW systems mounted on oil platforms. The Crimean port was one of the most EW-protected locations in the war.

Kyiv, which initially relied on outdated Soviet equipment, says it has improved its EW capabilities thanks to systems produced domestically and supplied by western allies, although the details are kept secret.

Ukraine’s Bukovel system, which can be mounted on vehicles, detects drones, jams their data transmission and can block satellite guidance systems including Russia’s Glonass. Praising its effectiveness, Ukrainian troops have called on the government to produce many more units.

A new Ukrainian system, code-named Pokrova, can, according to some reports, counter missiles by blocking their guidance system.

Pavlenko, from Ukraine’s general staff, said it was crucial for the soon-to-be-delivered F-16 fighter jets provided by western allies to be equipped with modern EW systems, adding that Kyiv was working with allies on this request.

He boasted that Ukraine’s EW systems had been used to capture prized Russian UAVs like the Orlan and had tricked other drones into flying back to Russia.

Pavlenko said Ukraine could be used as an EW laboratory, though he admitted that some western militaries were reluctant to share technology.

“Any sophisticated high-tech equipment has software that can be affected. And this is the future,” Pavlenko said. “This approach is more promising, and where best to test it if not in Ukraine?”

Increased destruction of most modern Russian T-90M tanks in Ukraine


The T-90M Proryv-3, a latest-generation Russian tank, has suffered significant losses in Ukraine. For instance, one incident involved the tank
being hit by a portable anti-tank weapon, causing the ejection of its turret due to the detonation of ammunition stored underneath. Recently,
there has been an increase in the destruction or neutralization of these tanks, making it interesting to delve into this Russian Main Battle Tank.

US Patriot Missiles in Ukraine Demonstrate High Efficiency in Intercepting Russian Aerial Threats


According to combat experiences shared by Ukrainian soldiers, the American Patriot air defense missile system has demonstrated high efficiency in
intercepting and destroying aerial threats, such as ballistic missiles and drones, launched by Russian forces against major Ukrainian cities.
Notably, the Patriot system has also shown its capability in intercepting the latest generation of Russian missiles, including the Kh-47 Kinzhal
hypersonic air-launched ballistic missile.

Une nouvelle menace est apparue dans le ciel ukrainien : le Shahed 238. Il s'agit d'un drone kamikaze doté d'un réacteur, là ou le Shahed 138 était doté d'un moteur à hélice. L'engin est donc nettement plus rapide, et par conséquence, plus difficile à intercepter.

@Vampiro .
(par conséquence, plus difficile à intercepter.)
Pas forcément
Sa trajectoire va être plus prévisible en plus leurs réacteur émettra plus de chaleur pour les MANPADS.

Oui, vulnérable aux missiles, mais du coup ça rend son interception plus coûteuse. Pour avoir de bonnes chances de l'abattre, tu es obligé de tirer au missile, là où le Shahed 136 était simple à abattre à la mitrailleuse de .50 voire au fusil d'assaut. Si à chaque fois que tu dois abattre un de ces engins tu dois "gaspiller"' un Stinger à 25.000 dollars ou un Patriot à 3.8 millions pour abattre un de ces engins...

Sans compter que la défense a moins de temps pour réagir : le Shahed 138 volait à maximum 180 km/h, ici on serait à plus de 800.

A mon avis les Russes vont probablement mixer les attaques, mêlant Shahed 136 et 238 pour compliquer l'interception avec des engins volant à des vitesses très différentes.

Ce n'est pas les Shahed a 10 000 dollars qui se font abattre c'est les missile anti aérienne a plusieurs centaines de milliers de dollars qui se font abattre par les Shahed

Maintenant le moteur du Shahed s'éteint quand il arrive proche d'une cible pour qu'on ne puisse plus l'entendre arrivé.

Je pense que c'est le principe :

1° User la défense ukrainienne en balaçant des drones peu coûteux en quantité ;

2° Une fois qu'il y a des trous dans la raquette (stocks ukrainiens vides ou quasi vides), envoyer des missiles plus lourds - et plus coûteux - sur les cibles.

Aussi, les Shahed 136 et 238 peuvent servir à appâter la défense sol-air ukrainienne et lui faire dévoiler ses positions avant des tirs de contre-batteries.

P.-S. Vous savez si ça veut dire quelque chose "Shahed" ? Pourquoi ils ont appelé ces engins comme ça ?

Russia to field in Ukraine new PBK-500U guided cluster glide bomb with stealth features


As reported by TASS on January 10, 2024, the Russian state-owned company Rostec is preparing to begin production of its latest aerial bomb,
named the PBK-500U SPBE-K Drel ('Drill') glide bomb. This advanced munition is designed for use against armored vehicles, ground-based
radar stations, and control centers of missile systems. It also incorporates features intended to reduce its detectability by enemy radar systems.


Similar to the basic version of the PBK-500U, the Drel likely employs an inertial guidance system (INS) supplemented by satellite correction
systems like GPS and GLONASS. (Picture source: Yandex)
