So a less maneuverable ship that you can tank up on shields and armor but not pay actual penalties for the loss of manoeuvrability?
Sure a loss of „actual penalties“. I can‘t explain it, so that you see what I see xD Hm..
It is a mounted gigantic weapon, let’s say on the bottom of the huge „Boa“. If you buy the ship, you will get the ship with a -installed gigantic mounted slot as standard like the Fighter bay. Let’s say the ballistic cannon comes along with the ship, so this mounted slot has a retracted ballistic cannon. If you want to use it then you just fly outside the station and switch into the Gigantic Gunner seat. Now the weapon extends, looks like let’s say a small round tower with two massive guns and two medium.
You can buy a few different gigantic Weapons, let’s say a Plasma Cannon (Primar fire) with two medium gimballed Pulse lasers as secondary fire. This cannons are big, bigger then size 4 weapons.
So and the Boa has only one of thoes gigantic weapons. But sure it will get his designed other weapon slots too. Let’s say 1 Huge 4 Large 4 Medium 2 Small. The maneuverability of the Boa is definitely less designed then our large ships. Now its your decision what you want to install in these Huge, large, medium and small weapons. If you use Fixed weapons then it will be hard to get your target in front. You can also buy turreted weapons or gimballed, what ever you like.
But the gigantic weapon doesn’t have this options.. its a manned Turret. You hire a npc crew member and move her/him into the weapon, now you can use it as a Turret with the fire power of around 1Huge+1Large for Primar fire and two Medium for secondary fire. Let’s say the movement speed of the gigantic weapons is like a large Turret, but that’s should be frontiers design job ^^
You can also use it itself, then the npc crew member takes the ship control.
There was some players except me, who want that ships needs more people (npc) for run it. So that’s would be also be the case a bit¿ You can have a other crew member in your fighter and a third one in the Small ship in your Small landing bay at the Boa. If you want to do this, then you need all three possible npc crew members in your Team or a Player takes a place

But you can also have two players in with three npc’s , at the secondary fighter or at the normal gunner seat. It’s their choice, i mean they can go into the gigantic seat or into the small ship

Its expansive, i mean three crew members cost you each approximately 2-15% of your earned credits, and this i think would be fair.
After all it’s just one Gigantic weapon in the Boa. If you want to win against a A rated cutter, then you still need your other weapons too.
