How does GPL prevent Raytheon from using their software?
Open source is open source.
If I don't want my software being used to make weapons I just won't make weapon-related software. If they wanna use my 3D graphics library to display their missiles, cool, idgaf, that's like putting ethical burden on a restaurant that serves food to soldiers because a military base was built nearby. The restaurant was there before the military base opened, and it's not like they're gonna use their food to kill people.
