Ukraine plinking a Russian GPS-jammer with a GPS-guided bomb. Ukrainian drones blowing up Russian drone-jammers. Ukraine’s cruise missiles striking Russian air-defense sites whose missions include, you guessed it, shooting down cruise missiles.
Russia’s 23-month wider war on Ukraine has seen a lot of ironic, darkly-hilarious clashes. The latest was also one of the quickest between setup and punchline.
On Tuesday morning, Russian media announced the deployment, to Ukraine, of Russian forces’ latest high-tech counterbattery radar. A few hours later in southern Ukraine, the Ukrainians blew it up … with artillery rockets.
The irony deepens. In theory, a Russian Yastreb-AV radar would help to protect Russian troops from Ukraine’s American-made High-Mobility Artillery Rocket Systems launchers—its HIMARS. Now guess what the Ukrainians used to destroy that first Yastreb-AV.
That’s right: HIMARS.
The counter-battery radar doesn’t prevent artillery from working; it makes it dangerous for them. Theoretically the units that took this out could already be destroyed after having had their coordinates calculated and counter-battery fire immediately called down on them.
In practice it was just setting up, having been tracked to its location, and possibly wasn’t working yet. Also the GMLRS rockets fired by HIMARS are not ballistic - they execute a counter-battery-confounding turn. And the salvo is fired quickly after which the vehicle immediately leaves - it can park, get ready and fire a full salvo in under a minute. When the first rocket is detected a couple of minutes later, the launcher will already have driven off and counter-battery coordinates will not be that useful/
To add to that, this war has shown the importance of shoot-and-scoot. Towed artillery with long setup and teardown times are too vulnerable to drones. Might be the end of an era for towed artillery.
The same holds for radar. A radar literally shines a light that anyone looking for it can see. Pinpointing a radar is trivial. Mobile radars can’t stay and detect from a location for very long, without risking an artillery strike. Fast setup and teardown times are crucial, along with a strategy where multiple mobile radars cover for each other, so detection is never offline for long.
For some radar. This is actually the biggest gap between western capabilities and Russian - Russian does not make proper digital AESAs, which are very critical for LPD operation. If you only transmit in scanning pencil beams, it is extremely difficult to locate you.
This was an interesting conversation to follow, but I got lost on the acronyms. Could you expand those please? TIA (thanks in advance)!
Just taking some guesses based on a minute of googling:
digital active electronically scanned array (AESA)
Low Probability of Detection operations
So normal radar is like a lightbulb. You can tell where it is from any direction. The right kind of AESA is like a laser. You have to more or less be right in the path to detect it, and you have to detect it to locate it.
You can look up what the acronym AESA means without unstanding it.
Take two speakers that are next to each other. If they emit a tone of the same frequency, the sound will “add up” and be louder in some directions, and cancel out to some degree in others.
A phased array radar uses the same concept, but now on electro magnectic waves, instead of sound waves. And with much more than just 2 emitters. By carefully choosing the phase of the signal in each emitter, itnis possible to both choose a single direction that receives the strongest signal, and to tighten the spread around that direction (creating a pencil beam). This is what the dish is for in standard radars.
If these phases can be fully controlled electronically, you can steer where you are looking, and swap between wide and narrow search beams in an instant. However, that is not a trivial thing to produce. So cheaper phased array radars use mechanical systems, or partial electronic steering (example: only horizontal steering).
Speed is the essence of war, and speed has definitely been the deciding factor. That and logistics. Last I read, Russia was still supplying their military with unpalletized, man-portable crates that take teams of men hours to unload, while Ukraine has their goods loaded onto pallets that take a couple guys with forklifts a couple minutes to get off the trucks and to the people who need them.
What? Ukraine is effectively using towed artillery, Russia isn’t really using anything effectively so there’s an argument for them I guess.
Russia has a very long kill chain, sometimes taking hours or days to respond to threats. That might be why towed is still effective for Ukraine.
On the other hand the artillery mounted on trucks seems to be quite effective.
Stuff like the Caesar can park, fire 6 shells and leave in less than 3 minutes.
Unlikely - it’s too cheap to get rid of. It will degrade its effectiveness as it’ll need to deploy, fire very few rounds, then leave, unlike traditionally where a battery might fire loads of rounds before moving off.
Reportedly, the Ukrainian reaction to seeing an RCH 155 demonstration was “we’ll take 100”, those things can shoot while scooting. Alas production is going to take a while, Ukraine will be the first user.
Even if it was fully operational, Western artillery used by Ukraine is more precise with longer range than Russian, so they can target the ruskies with less risk.
