Ukrainian Defensive War against the Russian Invasion - Mark IV: The Partitioning of Discussion

Fair. As to them being used... I think the Russians are busy trying to figure out how to use them. They have a problem, so they created a solution... but they now have a problem of how to implement the solution. It turns out a naval turret designed to run off ship power, operate using water cooling, and use 100+ pound ammo canisters isn't the best solution for a mobile, land-based anti-air platform.
the mtlb can go on water; they added a naval gun on it.

It's a good replacement for the Moskva at any rate

James Vasquez has deleted his Twitter & gone dark, after he's been accused of hustling donations & stolen valor:

First; the big one that could end with him having a pair of broken arms before leaving Ukraine, at least.

Da Vinci was a pretty big deal, and once word gets around Vasquez did him like that..... well.

And not that it's surprising, but the tranny Sarah-Ashton Cirillo won't let an opportunity to cancel someone go to waste:
RDT_20230322_2245433556727333121073885.jpg
:story:

Hell.... even that tranny Cirillo turned out to at least be a competent soldier & seems committed to that particular cause; although they're still parlaying the experience into views & Twitter clout. The payoff for them just will be on the backend, after the fighting is over.

But honestly I'm not surprised, especially if he was profiteering & hustling on the side; Vasquez always struck me as a tourist who could fake the funk, but definitely not the kind of guy you'd want in your platoon, for a variety of reasons. That he was never officially attached or rolled into any particular brigade of note always interested me, and noticed he only showed up in videos with his own "team" of TDF/militia types, or while tagging along on someone else's op. I always expected he'd quit sooner than later or get killed.

Vasquez truly reminds me of an old & fat reservist & KBR contractor I worked with in Iraq, who's peak life moment was rolling over the berm for the first time back in '91. From listening to him talk endlessly & boast about his vast combat experience, to an average civilian or foreign national audience it would've sounded like he had been in the shit constantly ever since the Storm. But downrange nobody took him seriously, he got called out on his bullshit several times.

That guy was exactly the kind of asshole I hated as a fellow NCO because the minute he stopped to talk, work would cease as everyone started smoking & joking instead. He had all the answers, but nothing ever seemed to get accomplished. And the worst part was he skated on deploying with his reserve unit as an NCO (because of his KBR contract), but still expected his KBR coworkers to address him as "sarnt". I even saw him try to lock-up another KBR mechanic to parade rest, for calling him a fat old fuck, and got laughed at to his face.

So yeah, tldr:
Vasquez.... don't be like that guy.

Related to the Ka-52 Hostomel video:
They have seriously bad vibes:

Russian Ka-52 Hokum attack helicopters fighting in the war in Ukraine are suffering from a major vibration issue that could, according to at least one expert The War Zone consulted, decrease reliability and, potentially, be unsafe. At best, according to assessments we’ve received, the vibration is likely to reduce the efficiency of the weapons these helicopters carry, and may also restrict weapon life. In turn, this could have an effect on the capability of the Ka-52, one of the most widely used Russian helicopters of the conflict so far.

Video clips showing Ka-52s operating with their stub wings rapidly bouncing up and down began to appear on social media in recent weeks and there has already been speculation that the issue could lead to “mechanical failures and vibration-induced fatigue.”


Until now, however, there has been a lack of expert input on this matter, which The War Zone has addressed by talking to four experts in the field. Three of those have chosen to remain anonymous since they are either still serving or otherwise work on behalf of the military in their respective countries.

The two-seat Ka-52 is an attack helicopter with an unconventional coaxial main rotor arrangement, obviating the need for a tail rotor. It’s fitted with a two-spar stub wing on each side of the fuselage. These ‘wings’ have no high-lift devices; they serve exclusively to carry armament and other stores, as well as sensors and flare dispensers at the tips.

The videos showing vibrating stub wings on Ka-52s involved in the Ukrainian campaign include helicopters cruising in level flight, on the approach, and landing vertically. In each case, the stub wings are fitted with heavy loads combining fuel tanks, anti-tank guided missiles (ATGMs), anti-aircraft missiles, and pods for unguided rockets. In fact, videos showing such heavily laden Ka-52s are hard to find before the war in Ukraine, suggesting overall stores weight may play a role here.

First off, we spoke to an aeronautical engineer whose professional experience includes heading up the future projects division of a major helicopter manufacturer.

He quickly identified the vibration issue as “vertical bounce at (maybe) blade passing frequency.”

Ultimately, a helicopter rotor acts like a kind of vibration filter, with the main variation in load that gets passed down the rotor shaft being a vertical input that varies according to the blade passing frequency.

Blade passing frequency differs from helicopter to helicopter, based on the number of rotor blades. A Bell 47 or a JetRanger, for example, has a vertical load component of two per revolution, as each has a pair of rotor blades. For a five-bladed S-61 Sea King, by contrast, the largest single component of vibration would be at the blade passing frequency of five per revolution.

As for the Ka-52, this has two three-bladed rotors and each of these assemblies will produce the largest single component of vibration at a blade passing frequency of three per rev. As the two rotor assemblies turn in opposite directions, it’s conceivable that some loads will be reduced, and others reinforced as a result.

Regardless, the main thing to consider is whether there is anything in the stub wing and stores pylon structure with a natural frequency that, in a particular vibration mode, coincides with the main vibratory load frequency coming from the rotors.

Were that the case, that part of the structure will be excited in that mode, “producing increased structural deflection and an adverse environment for the weapons being carried,” in the words of our engineering expert. “If, for example, the second mode of vertical bending of the wing had a natural frequency close to the blade passing frequency, then the wings could busily ‘flap away’ as a result.” Based on the videos we’ve seen, that would appear to be a highly probable conclusion.

Interestingly, the same expert told us that he’d watched a Kamov flight demonstration at the manufacturer’s Lyubertsy test center in the 1990s, but had not witnessed anything like this vibration issue.

He did, however, note that perhaps the most troubling feature of the vibration could be its effect on the missile armament carried.

“Typical issues would be ability of missile infrared sensors (if used) to obtain lock-on (particularly if there are any components sensitive to that frequency).”

In each of the videos that appear on this page, the Ka-52s are indeed carrying missiles with infrared seekers, namely the 9M39 Igla-V weapons (air-launched versions of the familiar SA-18 Grouse man-portable air defense system), two of which are seen on each outer pylon. It appears that these air-to-air weapons only began to appear a few weeks into the conflict, reflecting the lack of Russian air superiority.

“The other issue might be weapon life — my recollection is that this sort of vibration environment would be detrimental to life.” Missiles, whether Igla-Vs or the ATGMs carried in clusters on the inboard pylons, are sensitive pieces of equipment and don’t take well to being buffeted or otherwise thrown around. Excessive vibration could well be passed on to the missile seeker, motor, warhead, or control systems, with detrimental results.

“It also looks as if, with this weapon load, there is a wing vertical response feeding into the weapon motion,” the same expert concluded. “All I can say is that it doesn’t look good.”

The next individual we spoke to is an ex-military rotary-wing pilot and a weapons test engineer with direct experience with stores trials involving military helicopters.

“This is clearly high-amplitude vibration and might shorten carriage life,” he told us, immediately identifying the potential for damage to the weapons being carried. This could mean the movements imparted by the vibrations exceed the limits imposed by the design authority, or simply that the stores being carried become progressively less reliable “and even unsafe in extreme cases.”

While that would apply to the missiles, it would potentially also affect the sensors carried on the tips of the stub wings, associated with the self-protection system. This, of course, is vital for the survival of the Ka-52s in what is increasingly contested airspace, with a proliferation of man-portable air defense systems (MANPADS), as well as other, less conventional weapons. While reliable figures are unavailable, it seems the Ka-52 has taken heavy losses so far, with firm evidence of at least 13 examples seriously damaged or destroyed, although which of these were lost to enemy fire, pilot error, or mechanical issues, is similarly unclear.

“I experienced the [vibration] problem, now many years ago, as a helicopter pilot, and then seeing colleagues work on helicopter carriage of weapons,” the weapons test engineer explained. “As you can imagine, the vibration pattern is a combination of harmonics of the natural frequencies of the main rotor(s), (and tail rotor for helicopters so fitted), and aero/structure reactions.”

Finally, we discussed the videos with a helicopter pilot currently serving, who has direct experience of trials involving the service clearance of weapons and stub wings.

“This looks like they haven’t even heard of damping,” he remarked. “My general understanding is that aside from any impact on accuracy it’s going to significantly reduce the life of the weapon. So rather than 100 air carriage hours it could be as few as 10 before the missile won’t work. All the shaking generally not being good for the electronics, or the explosives, which could become more sensitive.”

The same pilot noted that “we definitely wouldn’t clear something to operate if it was doing that,” before adding that he expects the effect might not only be felt by the weapons but also by the wing itself and the stores pylons.

An alternative theory to the vibration issue was provided by another experienced helicopter pilot, who goes by the Twitter handle @thenewarea51. A commercial air ambulance pilot, they noted that this could also possibly be a track-and-balance issue with the rotors. This takes hours of time to do after maintenance on a regular helicopter, let alone a six-bladed contra-rotating configuration. It is dangerous to fly without it, but it isn’t clear just how hard Russia is pushing its helicopter fleet at this point in its invasion of Ukraine.

With the Ka-52 having been subject to evaluation by the Russian military since 2011, and already having seen combat service in Syria, it would seem unlikely that the vibration issue hasn’t been identified before.

With that in mind, it could the that the Russian Aerospace Forces and Kamov deemed that the problem was not severe enough to disrupt daily combat operations and that the possible effects on the weapons was judged a price willing to be paid. After all, if weapons are being expended on most sorties, then the effect on missile service life ceases to become such a big issue.

There is also the possibility that the Ka-52s being used in Ukraine are carrying heavier weapons loads than is usual. As noted, the aircraft exhibiting vibration all carry fairly big loads of stores, with the fuel tanks, in particular, adding significant weight, especially depending on how full they are. This factor, too, could affect the vibration levels.

It’s also worth bearing in mind that the issue may well be isolated to a portion of the fleet and, with only a few videos so far, we don’t have a real sense of how widespread this vibration issue could be. Perhaps, it afflicts only older-production helicopters, for example.

While the subject matter experts we spoke to all agreed that the vibration looked like it could be a problem, especially on sensitive weapons, it’s clear that the Ka-52 remains very much heavily engaged in the ongoing fighting. It will be interesting to see if any measures are taken to address the vibration, especially if it starts to take a toll on airframe as well as stores.

He was called out as a fraud at least 6 months ago by volunteers like TheDirtydozen, but because he had more followers and was defended by Malcolm Nance it got no traction.

Now after the Troon called him out all these other volunteers are saying that they knew he was a fraud, but said nothing because of the Twitter backlash they would get. Cowards.
 
Guys, I think Russian morale might be a smidge on the low side.


Seriously how retarded do you have to be to not just surrender in this scenario?

Edit: People ask why Frodo didn't just fly on the eagles. But have you ever wondered what Gollum getting drone striked would look like?

TBPF: even if we assume he's a not warcrime committing zigger, he's probably gotten lots of propaganda about what those other, bad Slavs will do to him if they capture him. Being he's a Slav and knows what he'd to do to POWs, and all the assrape his own ALLIES have been doing, he decides he doesn't need to go there.
HE also might be more injured than it seems. I also remember seeing a guy who looked like he was paralyzed from waist down opting to not see what the Soviet VA is like. Which isn't the choice I'd make, but I can understand it.

Possible also he's a officer or something, with the plans for the capture of Bakhmut in two more weeks, and doesn't want to risk that he'll talk and ruin the operation.

It's finally happening. Russians are sending T-55's and T-54's into Ukraine. They are raiding museums for tanks older than most of the people fighting the war on either side.

Ok, enough click baiting. They could be sending them off to be shipped to country who bought them. But keep in mind the vatnigger cope was that the T-62's weren't going to be used on the frontlines but they were found on the front lines.

If they are sending T-55's and T-54's to Ukraine we might get to see them sending in WW2 tanks. If they have any left. But they supposedly scrapped or sold off all their T-62's and older post WW2 Cold War era tanks. Yet here they are with T-62's in Ukraine and T-55's and T-54's on train cars.

I would like to point out that the 25MM bushmaster autocannon on the Bradley can penetrate the front of a T-62. I am sure it could penetrate a T-55 anywhere.

Let the vatnigger cope begin. LOL

 
'Russian T-90M tanks best in world, outperform Leopard, Challenger, Abrams', and will produce 1500 this year
- drunken midget Dmitry Medvedev

Archive

Moscow: Russia’s Security Council Deputy Chairman and ex-president Dmitry Medvedev claimed that the Russian T-90M tanks are currently the “best in the world”. He added that these tanks outperform Leopard, Challenger and Abrams in terms of tactical and technical data.

“In my opinion, this (T-90M tank) is now the best tank in the world… It is certainly better than Leopard, Challenger, Abrams (tanks), including in terms of its tactical and technical data, even in terms of such a component as mass,” Medvedev said, Sputnik reported.

Amid the Russian invasion of Ukraine, Medvedev further informed that Moscow will make as many as 1,500 tanks alone this year. “You can calculate how much our enemy will get, even according to the most optimistic calculations,” he added.

The latest version of the T-90 tank series, the T-90M Proryv is an upgraded version of the base T-90 tanks, Apart from a new turret module with multi-layer armor, improved crew protection thanks to the placement of its ammunition rack outside the crew compartment, these tanks also feature an improved main gun – 125 mm 2A82 – the same gun fitted on prospective next-gen tanks such as the T-14 Armata.

Besides that, the T-90M also have an automated Kalina fire control system ( :story: ), a remotely controlled 12.7mm Kord machine gun, a Relict dynamic defense system, and fifth-gen digital communication system, according to reports.

Also, T-90Ms have an advanced active protection system for anti-tank and anti-missile defense, named Arena-M. Back in 2018, the military had announced plans to upgrade all of its T-90s to T-90Ms by 2025.

According to reports, India is the biggest operator of T-90 series tanks. Its inventory consists of as many as 1,100 T-90S “Bhishma” MBTs.

‘Declaration of war’

Meanwhile, Dmitry Medvedev has also warned that attempts to arrest Russian President Vladimir Putin abroad would be seen by Moscow as a “declaration of war”. His comment came after the International Criminal Court (ICC) issued a warrant against Putin. The ICC, based in The Hague, last week announced an arrest warrant for the Russian leader, accused of deporting Ukrainian children, AFP reported.

Medvedev, who served as the Russian president between 2008 and 2012, said, “Let’s imagine — it’s clear that this is a situation that will never happen — but nevertheless let’s imagine it does.

“The current head of a nuclear state arrives on the territory of, say, Germany, and is arrested. What is this? A declaration of war against the Russian Federation.”

Medvedev said that if this happened “all of our means, rockets and others, will fly on the Bundestag, in the Chancellor’s Office and so on.”

Further, he added that the ICC’s decision will make dire relations with the West plunge further.

His comments came two days after Russia opened a criminal investigation into ICC prosecutor Karim Khan and several other ICC judges, saying their decision was “unlawful”.

The Hague-based court had also issued a warrant against Maria Lvova-Belova, Russia’s presidential commissioner for children’s rights
 
I think a lot of foreigners will find LazerPig's video on Armata very informative. Not just regarding the tank itself but the underlying context in which it was conceived.
Explaining Russian mentality and society, showing you why exactly we ended up in this situation.

Found an interesting quote in the comments: "The army that is well organized and up to the task doesn't have heroes - because it does not need them to get the job done."
It highlights what bothers me about Russia's unhealthy obsession with heroism - it's a society willing to throw away human lives instead of trying their best to avoid unnecessary sacrifices. The cult of war encourages dying for the motherland (whatever the fuck that is), according to them it's literally the best thing a man can do. Not living a productive and fulfilling life raising a new generation, but dying for the glory of monke tsar in a dirt hole somewhere, that's the ultimate aspiration. It makes me sick.
Unfortunately, a lot of Russians are too stupid to see it for what it is. Authoritarian regime plugging gaping holes created by their incompetence with human meat. Your heroism doesn't mean jack to them, it's just a means to an end.

Probably spoiler that shit if you still can.
I still don't get why they don't surrender. There's a clip that was posted recently where they're clearly offered the option, even though it was some sort of Azov trench cleaning ops. The dude, allegedly from the Far East parts of the Russia, seems to refuse.
What fucking sort of lunatic does that? They must be drugged, cannot be explained otherwise. I don't think that being propagandized that Ukrainians will torture you and that they eat Russian children for breakfast can result in these behaviors. Must be combined with drugs of some sort.
 
It will last longer than a Leopard 1
That really depends. The leo is meant to be used in a high speed manoeuvre war, where the T55 more of a conventional heavy-armoured beastie. If the ukranians try and use the leo the same way they'd use a contemporary Russian tank, then of course it won't last long. The T55, by contrast, is meant to operate in a more conventional way, but is vulnerable to the higher velocity shells the leo fires.

With that out of the way, I'm now legally obliged to remind everyone that the Leopard 1 is the wonderweapon that will be leading the victory parades through the streets of moscow in six weeks, because I am a good friend of the great nation of Ukrael and the CIA.

There's only so many ways the Leo1 can be utilized. The UAF isn't going to be hauling off across the steppe.

Also, they aren't going to unlearn doctrine that's been pounded into their heads for decades
