Well, they certainly have the ability to manufacture those parts themselves, but you’re absolutely correct that they would have to deal with a massive disruption to their existing supply chain. If they didn’t take the appropriate measures well ahead of such a drastic step it certainly would ground the fleet for quite a while, until they got domestic production sorted out.

Ground based. This doesn’t exclude it having components onboard the aircraft.

And yes, fundamentally, tracking inventory and maintenance requirements is all it does. I apologize if I oversimplified the details a little too much, but I’m trying to keep things readable and not get bogged down in details, and it wasn’t relevant to my point. And if you’d thought about it a little longer you’d quickly realise that it’s not relevant to whatever point you seem to be trying to make either.

ALIS includes a component that is carried aboard the plane and provides telemetry. Fact freely granted.

And entirely irrelevant to the notion I was addressing. The fact that ALIS transmits information from the craft is not germane to the point that it cannot be used to affect the operability of the craft - and that’s according to the people who actually use and maintain these systems. I’m not making these claims; the experts are.

But none of that occurred to you because you are so desperate to try to find some kind of conspiracy theory here. To the point where even bothering to write this reply is pointless, because I can only assume that you’ve decided that I’m some kind of deep cover CIA agent here on direct orders from Steven Miller.

It is fucking exhausting talking to you people. I genuinely cannot comprehend the insane degree to which any tangential detail gets fantasized and catastrophized into an elaborate work of Tom Clancy fan fiction.

I don’t even like Carney all that much, and I still feel sorry for him having to interact with that moronic piece of shit. Imagine having to have a phone call with a world leader just so that you can explain to them that everything they said on their crappy twitter clone was wrong.

Also the idea that there is no possible way to sabotage these planes via technology is comical.

Now this is a classic example of making a completely different claim than the person you’re responding to, then countering that, and acting as if this means you’ve countered any of their claims. Peak bad faith argument. Well done.

Joachim Schranzhofer, the head of communications at German defense company Hensoldt informed the local media outlet Bild

Here’s the source that previous poster failed to include for this part: https://militarywatchmagazine.com/article/german-policymakers-concerned-american-kill-switch-disable-f35

That article is largely a pile of meaningless sensationalism with very little in the way of meaningful claims. All of it more or less boils down to this;

with analysts specifically observing that the Autonomic Logistics Information System (ALIS) system which is heavily centralised in the United States could easily be used to disable the fighters.

This is a claim that’s been repeated a bunch in the armchair general circuit, but without any of the actual context, and mangled beyond recognition from what the original sources say. ALIS cannot “ground” a plane in the sense of “Prevent it from taking off at the press of a button.” It’s a logistics management system. All it does is track parts orders. The US could shut people out of it, which would be a massive pain in the ass, but it wouldn’t actually prevent planes from flying.

Here’s a source that actually digs into a little better: https://www.defensenews.com/air/2016/04/27/could-connectivity-failure-ground-f-35-it-s-complicated/

First, some context (from the article) on what ALIS actually is:

ALIS, often called the backbone of the F-35 fleet, is an information technology hub that is used to plan missions, track aircraft status, order spare parts, and manage sustainment of the plane. By contrast, legacy aircraft use several standalone systems to perform these daily functions. ALIS is the first system of its kind to manage daily squadron operations, track sustainment trends and protect sovereign information — all in one hub, according to Dave Scott, vice president of training and logistics solution business development for Lockheed Martin Mission Systems and Training.

When the previous poster’s quote source talks about the mission planning system, this is what they’re referring to (I’m going to skip right past their assertion that the kill switch “is more than just a rumour” because the article presents this claim with absolutely zero evidence, context, or expansion; it’s just thrown out there and treated as gospel truth. Extraordinary claims need extraordinary evidence).

Anyway, from the article I cited;

Losing connectivity to ALIS would be a pain, but hardly fatal, the JPO contends. If jets are unable to use ALIS — a ground-based system that provides sustainment and support, but not combat capabilities for the jet — the F-35 is still a usable plane. In fact, the worst case scenario would be that operators would have to track maintenance and manage daily squadron operations manually, just as older jets do.

Emphasis mine. ALIS cannot “ground” planes, it can only make it harder to maintain them. And only to the extent that it’s already hard to maintain existing planes like our CF-18s. This is a solved problem. We know how to do this. It’s not a magic kill switch, it can’t shut anything off. It’s just an inventory management system.

Stoat (formerly revolt) would be my vote. It’s basically an open source clone of Discord. It might not have every feature you want, but the basics are all there, and the UI is pretty much indistinguishable so even non-techie friends won’t mind the switch.

Again, you’re claiming that every single country in NATO missed this. All of them.

That’s insane. If you’re still pushing this line of reasoning I have nothing else to say to you. I can only assume you also believe that COVID 19 was a Canadian Military psy-op, the moon landings were faked, and that lizardmen from the hollow earth secretly control all the world governments.

It’s a waste of money if your primary goal is defending against the US, yes. Which is another reason why all the handwringing about how the US could potentially compromise the F-35 is really kind of silly. Truth is, if they wanted to attack us, they wouldn’t need any kind of magical “Kill switch”, they could just rely on old fashioned air superiority.

I’m still a huge advocate for signing a deal for the Gripen anyway (as stated above, I like the mixed fleet idea the best), because it gives us a lot of economic advantages, allows us to become an exporter of fighter aircraft to the rest of NATO and numerous other countries, and starts building up domestic air production that can then be converted to putting out Saab’s new 6th Gen fighter when that’s finally ready for prime time.

But if we consider our biggest realistic air threat to be Russia - Note that I said “biggest”, not “only”, trust me I am in no way dismissing the threat of a potential US invasion (in such an eventuality I’m on the list of people who die or get arrested in the first 8 hours, I do not fucking need to hear it) - then yes we absolutely do need the ability to patrol our own skies, especially if we end up in what is still the more likely geopolitical scenario right now, which is that the US abandons any notion of defence obligations to their allies as they grow increasingly isolationist.

A contingent of, say, 40 F-35s doesn’t sound like a lot, but when those 40 planes have the ability to shoot down anything Russia can field without even being seen, that actually makes a massive difference in their ability to operate in our airspace. Right now Russia barely has 4th gen craft. The Felon is a lie wrapped up in a cool video package; it’s radar signature is fucking massive, and we’ve seen from Ukraine that Russia’s own radar capabilities are mediocre at best. And they have, optimistically, 6 of them. Anything else they have is so far outclassed by the F-35 that it would be like Challenger 2s going up against T-55s in Iraq. That’s a hell of a lot of deterrence for comparatively little cost really.

Have you noticed the very large, very aggressive expansionist autocracy on the other side of the arctic circle from us? Do you consider that maybe they might also be a potential threat?

Having a plane that massively outclasses everything in Russia’s fleet is not a bad idea, no matter what is happening to the south of us. A mixed fleet hedges our bets, giving us responses to both of the biggest threats we’re facing right now.

There are no F-35 parts only sourced in the US. Every country in the F-35 program has the ability to manufacture parts. The only thing the US controls is the firmware. The US can’t lock us out of buying or building replacement components, they can only lock us out of getting newer firmware updates (eg, we can still use the firmware we have, just can’t get anything past the point where they decide to cut us off).

Now that’s a completely valid concern; being cut off from firmware updates would seriously degrade the capability of that part of our fleet over a long enough time horizon, which is one of the reasons why we’re considering taking on a large order of Gripens as well. But it’s not a “Stop your planes from flying” scenario. Even without the latest firmware we’d still be able to put an F-35 in the air and have it engage and destroy targets.

You know, I did actually try to head off this line of reasoning by pointing out that a) we have the entire technical package, and b) there are no extraneous communications going into or out of a stealth fighter, of any kind.

Like, buddy, I really did try to give you all the pieces. I was like “Do I need to spoon feed ALL the conclusions? No, they’re a smart enough person, they’ll figure it out.”

No, that is not a remotely practical idea. First, no one is just accepting whatever random signals they get sent while flying a stealth fighter, or indeed any kind of fighter. Electronic warfare has been a thing for as long as integrated circuits have, we’re not idiots.

But more importantly, any capability you put in firmware has to ultimately talk to the hardware. There has to be an actual lever to pull, somewhere. It’s not magic. And firmware isn’t like the software on your phone; it’s not a general purpose computer. You can’t just run an app. There’s no kernel to allocate resources. Every single component on the F-35 has its own firmware, that runs that component, and the ability for those components to communicate with each other is strictly limited to what can actually be communicated at a hardware level. At some point any kind of “killswitch” would ultimately require hardware capabilities that would be obvious to anyone with the technical package, because those are exactly the kind of cascade failures that you would want to make impossible in the event that there was, say, an entirely normal, non-malicious bug in the firmware. You build these things to be failure proof, which makes it very hard to then sneak in ways to deliberately make them fail.

And I think the part that, above all else, you really, really need to wrap your head around is that we’re not idiots. Canada is an extremely technically capable nation. We didn’t buy this thing without experts reading the specs. And those same specs were read by experts from every other country in NATO, and none of them believe this kill switch myth is real.

So basically your theory stands on the assertion that you - John or Jane Internet User from Fucking Wherever - have, with zero access to any of the technical data, spotted a danger that all of the experts from every country in NATO missed, throughout the entire thirty plus years of the F-35 program, through around five different US administrations, all of them working in concert to conceal these capabilities, with zero complaint from Lockheed Martin, one of their biggest defence contractors, who don’t even mind that discovery of this capability would destroy their international sales forever.

That’s flat earth levels of self-delusion.

Rumours are we’re planning to split the difference; buy around 40 F-35s and 80 Gripens. This way we have a top of the line 5th Gen when we need it, and still get all the domestic and trade advantages that come with the Gripen, as well as building up our local defence capabilities. And down the line we can switch out to the 6th Gen fighter that Saab is working on, and build it right here in Canada.

It’s certainly the plan that makes the most sense. The RCAF really wants the F-35. The Carney government really wants the Gripen. We need to expand our military so upping our total fleet size is a good call anyway. And with how much lower the TCO on the Gripen is, we’re probably actually spending less in total over the next decade.

Just to clear up any confusion, this “Remotely bricks” idea is a total fabrication.

There is absolutely zero practical way to hide a killswitch in the F-35. All partners in the F-35 program have the ability to manufacture their own hardware. They have the complete technical schematics. The only thing the US controls is the firmware.

It’s a stealth fighter, not a Tesla. You don’t update firmware over the air. When that thing is flying, not one single mA of radio communicating goes in or out without very strict control.

There is literally zero mechanism by which this idea is possible, and a mountain of reasons why, as a conspiracy theory, it makes less sense than faking the moon landing. So much so that I can’t even get into it all here.

What is possible, and what NATO members are concerned about, is that the US could cut off access to new firmware updates. This would cause a nation’s F-35 fleet to slowly fall behind the updated versions in terms of technical capability.

Based on the rumours coming out of Ottawa, it’s increasingly looking like our plan is to split the difference; acquire somewhere around 30-40 F-35s (this new order would put us on the low end of that) and then around 80 Gripens. We’d have a top of the line fifth gen fighter that can hard counter anything Russia is capable of putting in the air, and we’d still build up a fleet that isn’t reliant on the US. Hedging in both directions.

Only when you have to write out to swap. In the case of something like ZFS, it stores data in RAM, looks for it there, then looks on the disk. So freeing up the RAM is effectively instantaneous; you just mark the space as free, then the other process writes into it.

The thing is, you can design an autoloader in a way that protects the crew.

The survability of western tanks isn’t just about where the ammo is stored, but how it’s stored. Western tanks, both with and without autoloaders, place all the ammo at the back, either of the turret or the hill respectively. More importantly, the ammo is stored in a heavily armoured compartment, which has blow-out panels on the outside of the vehicle; the ammo detonates the panels collapse, allowing the force of the explosion to spread out from the tank.

The problem with the T90 design (which is really just an updated T72) is that the autoloader is attached to the bottom of the turret basket. This means there’s no possible way to vent the explosion outside, other than by going through the turret, and through the crew along the way.

It’s part of ZFS 2.3.0, so it just depends what version TrueNAS is shipping with.

ZFS seems pretty RAM hungry

This is a common misunderstanding.

Short version; ZFS isn’t RAM hungry, it’s RAM aware. If your system has unused memory lying around, ZFS will use it to improve read performance. But it will give up that memory the moment anything else needs it.

and I don’t believe you can add new drives to an existing volume.

No longer true

This is 100% Trump. He thinks this is a big foreign policy win that he can carry into the mid-terms.

Of course, ending the war means convincing Russia to back down from the fight that they started, and the US no ability to do that because Trump still keeps trying to treat Russia like a friend. So any pressure they put on them will be meaningless. Meanwhile any pressure they put on Ukraine will basically amount to “End the war on Russia’s terms, or fight it without our help”, which is just a choice between two equally terrible options.
