No modern UAV has hardware capable of running an entire Windows installation. Think of arduino boards; those things can control huge robotics systems and they are very simple (and thus simple to debug). If you're designing a robot from the ground-up, why would you scale all the way to Windows? No one is going to be playing minesweeper inside the plane

I highly, highly doubt that you're right about this. If you happen to be right, you won't be for long. It might be that nobody wants to run Windows, but there is clear motivation, as well as hardware and software technology, to have a full-scale OS on an advanced UAV.

The google car is an exception where there is a lot of sophisticated software. UAV's like Boeing's and even the ones you buy online (with the open source software) are running on boards, not full-scale PC's with the ability to play a DVD.

UAVs are very complicated in terms of technology and engineering, but the hardware is simple because it's basically just running control loops on some board.

You're wrong to associate "UAV" with small "remote-controlled" airplanes. There are much more sophisticated things out there, and also in the works.

spoilers: Microsoft has a significant enterprise support organization, which the military is probably already dealing with, and Windows scales farther down than you'd think.

> why would you scale all the way to Windows?

For the only reasons such stupid thing happens: the clueless manager wants the machine to run a modern OS and thinks Windows is the most modern OS out there.

post-downvote edit: I am saying nothing about viruses like Stuxnet, designed as weapons tailored to infect specific systems, for which no OS would be safe, but how brain-dead is it to design critical systems that control airborne weapon systems around an OS that's vulnerable to each and every piece of malware known to man?

I'd say you're being downvoted because you're rather clueless about the qualifications of the manager designing unmanned drones.

Now I am curious. Why would Windows end up in such a system? I would expect an RTOS like QNX (which is not that hard to program).

I agree I am more familiar with corporate IT disasters where some pointy-haired boss decided Windows was the way to go instead of what would be the optimal choice, but I always expected flight-control software to be built with a great amount of attention to every detail.
