From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Linux in the military (lemmy.world)

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

For stuff that is still maintained but also legacy, military and contracting benefit from being a pretty insular community. Contractors are full of military retirees. What this does is give a pool of people who worked with the products for a very long time on one side who move over into maintaining them on the other, less knowledge is lost. It still happens and things must change eventually, but they manage to delay things where someone else like a bank might have a harder time when their knowledgeable employee leaves and they’re hiring people off the street.
