My team recently acquired a heavy freighter and a few additional parts and I wanted to get some rule clarifications about starships, build points, weapons, mounts, and the process for uggrading a starship.
First, when building a starship I understand the rules around build points and their distribution, so I am clear. I also understand that additional systems require additional build points and those increase as your party's APL increases.
The central problem I have is in understanding the upgrade paths available around weapon mounts and turrets.
Let's look at the Heavy Freighter as our example:
Mounts forward arc (1 heavy, 2 light), port arc (1 heavy),
starboard arc (1 heavy)
There are no turret mounts stated on this ship as it reads in the rules , as it does for say, the destroyer (turret 1 light).
For New Weapon mounts it states:
By spending 4 BP, the crew can upgrade a light weapon mount in any of the aft, forward, port, or starboard arcs to a heavy weapon mount. (This means for the Heavy Freighter I could spend 8 BP and upgrade both light mounts on the front arc to heavy mounts and have heavy mounts all the way around)
By spending 6 BP, the crew can upgrade a light weapon mount on a turret to a heavy weapon mount. (This does not apply to the Heavy Freighter as it has no turrets).
By spending 3 BP, the crew can fit a new light weapon mount
in any of the aft, forward, port, or starboard arcs with enough
free space. (This would allow the heavy freighter to fit 2 additional light weapon mounts on the cost of 12 BP - 6 for the port and 6 for the starboard. These could then be upgraded to heavy per the above rules.)
By spending 5 BP, the crew can fit a new light weapon
mount on a turret that has enough free space. (This would not apply to the heavy freighter as it does not have a turret.)
The rules then outline the maximum number of mounts per arc and per turret a ship can have based on it's size.
My problem is that I don't see anywhere nor any way by which you can add a turret to a starship that doesn't already have one based on it's frame.
Is this not possible?
Can a ship frame which does not have a turret in it's list of mounts have one added and if so, what are the restrictions and costs associated with it?
Also if a ship has no mounts listed in an arc (for example a freighter has no mounts for it's aft arc) can those be added?
