It probably does a lot more than that. It’s alway been rumored some US military tech could suddenly be turned “off” in the event of a war.

I couldn’t imagine a situation that would put Norway and the US on opposite sides. Since the military allows Norway to get F-35s they probably agree.




I have the feeling that if there were ever a war between major powers breaking out, the first thing that would happen is that a large chunk of military equipment and critical infrastructure on both sides would get bricked pretty much immediately.


And its financial system cut off. Like US disconnected Iranian banks from SWIFT, and there is no way today to bypass US financial system for international payments.


I've heard rumors of something similar about US anti aircraft systems, and this being a motivating factor in Turkey buying S-400s.


The S-400 is just objectively better than anything US is selling. The possibility of Patriot having a US killswitch is an afterthought if it was considered at all. It's also equally probable that the S-400 has a Russian killswitch.

The actual motivation for Turkey to pick the S-400 was entirely political. They are signalling allegiance to Russia. The US is now cancelling Turkey's F-35 order in response.


Turkey also wanted to have a technology transfer while having patriots. So, Turkey can use it for its own missile defence system. Apparently, It didn't happen.


Yet ironically, Turkey didn't get a technology transfer from the S-400 either. Once Putin got Erdogan committed, Putin knew he didn't have to offer much - Erdogan couldn't suffer a reversal.



Note that he doesn't have anything specific to point to - that's because he's merely trying to justify Erdogan. He must know that Turkey is going to get very few tech transfers:

Turkey has already a rocket-missile company [0]. So, I'm pretty sure Turkey does not need everything but only specific parts. What I think is that Roketsan will be able to manufacture its own s400-capable Triumph missiles. So, Everytime Turkey launches its own missile, It won't need Russia to replace its stockpile.

It's likely that Russia will allow Turkish missiles. However, that would not be a significant technology transfer. Technically Russia could do this merely by passing on protocols to 'talk' with the S-400, and letting the Turks create their own missile.

Even if some missile tech were to be transferred (I rather doubt it), the key part of S-400 is not the missiles - but the very sophisticated radar, control and EW systems.

Either way, it doesn't get Turkey much ahead in designing their own missile defence system, and leaves them dependent on a potential (even likely) enemy.


you wouldn't like to bet that the US are the only ones capable of turning it off, either.


“Off” in quotes. I bet it’s more like a software license. “you missed your 60 day update from Lockheed, your jet will stop working”


They fail to be fully operational after 30 days without connection to Lockheed servers, which is a problem even for USA because the connection is bandwidth intensive.


Reading your comment I pictured Geohot attempting to jailbreak an f35. It made me wonder can you brick an f35?


F35s do a perfectly good job of bricking themselves. On a consistent and routine basis.


I believe the F-22 software is written in Ada. I had a classmate in college who was in the air force. He said updating an F-22 took hours and if something happened you had to start over which happened often.


I can confirm that. Interviewed at skunk works in Lancaster. They shared this exact knowledge.


Command disablement is present on airframes dating as far back as the B-52.

Nondestructive remote command disablement (what you’re referring to) is probably a real thing. It would fit the same schema that other weapons systems already have (nuclear weapons, drones, satellites).


starting with the GPS network.


A prime reason why other constellations have been deployed or are currently being deployed, such as GLONASS (Russia), Galileo (EU), and BaiDu (China). India I believe also has their own, but it's not global, just regional.


With different definition of deployed for each constellation; Galileo has been down for weeks recently.


Galileo is still in deployment and a month ago they had an issue in the not-fully-redundent-yet ground segment that lead to 6 days with increasingly pure accuracy and partial outage.


Galileo was down for one week. It's also not yet at full capacity. I think it's expected to be finished next year.
