I believe ramming works fine in tactical combat, and will deal as much damage as possible to the planet in a single try (there isn't the ramming animation though if memory serves). It does not work with strategic battles to the best of my knowledge, even when tweaking strategies a lot of time; at least, I could not get it to work in my 2vs2 game with Parabolize.

It might be something about the angle of approach however, as the same happened (or happens? I have given up seekers since then) for seekers against planets. It would be odd for it to work in tactical and not in simultaneous though.
