So it’s no secret that some parts of the army in the USA and my country (UK) sometimes use legacy software like DOS for niche roles as they’re robust including older versions of Windows.
But… where does Linux fit in this? It’s a kernel OS that’s used in top of the line supercomputers, workstations, medical equipment and weather stations.
I imagine some aspects of this would be military secrets but how do they use it? I know that Linux was used for certain space projects with NASA but I’m talking about army applications.
TLDR : Does the penguin OS power shooty shooty machines and tanks
There are many reasons Microsoft software is only “good” (and I’m using that word loosely) in business and home settings. Can you imagine a rocket taking off and windows suddenly “rebooting to complete updates” (or whatever it is that it says along those lines)?

I’ll watch it right now and come back. BRB.
Edit: now I have to “arrr” that series and watch it. 🤣🤣
Rockets probably use a dedicated OS that is safety validated. Getting something validated for critical operations is a massive endeavor.
Correct, missiles use something like RTEMS, which is named because it was used for missiles (no really, it originally stood for Real Time Executive for Missile Systems) and the operating demands for missiles have to be real-time given their unique edge cases.
Disclaimer: I worked on RTEMS in College
Not only is it hard to get certified for things like rockets but they usually use a realtime os like red hawk (a red hat fork).
Running a full OS on a rocket? Why? It’s mostly some embedded stuff, some kind of arduino.
The launching platform though… maybe a minimalist OS with a curses interface.
That’s a real brain fuck. Now I need to go research this.
