You can see Saturn with any kind of telescope. In fact, you can see it without a telescope. For professionals and serious amateurs, the type of telescope used depends on what specific property or characteristic of Saturn they're interested in.

If you're asking if you yourself can do it, dream on, only the NSA or military would have access to that kind of technology.
