Ok cmdrs, my english is not good enough to express my thoughts, so excuse me for mistakes.
Let's not be fixed on this engineered FSD Booster idea, I wrote it's only one idea among others.
Let's see another something. Huge class ships. Federal Frigate, Imperial Destroyer, whatever names. They give the reason for highest
Federal and Imperial Navy ranks. This ships are, of course very expensive, 0,5 - 1 B Cr. they have class 9 and 10 slots. And now, Class
ten slot is enough for Micro Jump module, or class ten FSD which allows microjumps. You must use Tritium. This ships has docking bay
for 1 mid or 2 small class ships, because they can't enter any station. You need some crew. Preparation for microjump and cooldown time is much
shorter than Fleet Carrier. This ships can land on FC, because we can change 2 large pads (from 8) into 1 huge pad.
I hope this solution is still inside the rules of ED universe. But I'm not sure how big is FC FSD, and what's smallest possible capital ship-class FSD.
