I have some questions on planet bombardment with my fleets. I know i have to research the tech first, but are there any other limitations or requirements? Like is it limited to ship hull size, wpn type, number of ships? I have this planet i've been attacking and would like to soften up their defenses and 14,000 troops so my 3,500 troops can take the planet. I have 6 Frigates in orbit (med hull), but they only seem to attack the planet (when i target the planet with the FF fleets), when there is a enemy ship in orbital defense, and i have researched planetary bombardment a while ago. Am i missing something or is there something i dont know about?
