What is the maximum length of a cruise missile in fighter jets like the F-16 or Su-30?
It strongly depends on the jet, and you just mentioned, in the same breath, two radically different jets in terms of size. Consider the Su-30 and F-16 next to each other. What's the context for this comparison? If in doubt, just look at what munitions they carry in real life. By the way ability to physically carry a munition is just one piece of the problem. Integrating munitions on a jet requires considerable work and testing. So just because something a jet isn't normally set up to carry, can in principle fit, doesn't mean it can actually use the munition in question without quite a bit of work.
