Silly ship designs

Do internal docking bays cost the same as the mass of the ship you wish to
dock?

I had a silly idea: a 100 mass ship with a Nova Gun and enough internal
docking for two non-ftl Wave Gun frigates.

The idea is that your opponent would scan it and proceed to target a 50 damage
point ship when suddenly two more nasty area ships join in.

The cost is comparable to a standard Dreadnought. Since nothing else works
when you fire a Nova Gun, what else should be on a Nova Gun equipped ship
except cargo capacity?

I suppose shields might be nice to help it survive to get in range.

Topping the really silly fleet list of course would be the Wave Gun volley
squad. Team it up with an AA beam battleship and the Wave Guns destroy any
attacking missiles or fighters and the AA beams kill everything further away.

Lets see, 900 points for 10 Wave gun frigates and about 600 for the AA
Battlecruiser. Yes, there are lots of fleets which would kick its butt, but
a Wave Gun is the most cost effective Fleet anti-fighter
weapon there is. The ability to kill a whole squadron before it gets into
range? Neat.

I have a serious question: Once fighters have used up their fighting endurance
they have to head back to their Carrier, because they can no longer maneuver a
whole lot, shouldn't they be more vulnerable to ADAFs and other fighters?

Similarly, is a fighter group considered to be in combat in any turn in which
it is fired at?

There is a way to nail those pesky attack fighters, hit them well short of
their target ship with a piddling ADAF escort. Make them use up all their
attacks short of the fleet, or at least make them run home sooner.
