Re: Parasite Racks, External Mounts and Reactive Armour (Was Re:

Here is the original post which stipulates placement and mass 
restrictions for hull sizes:

Parasite Fighter Rack
[^]: symbol for Ex-rack squadron
30: Cost
1 :Space

A ship may mount 1 squadron of Parasite Racked fighters per 30 Mass of
Carrier ship.Since this squadron is carried externally, any damage
caused to the Carrier vessel will destroy the Parasite Racks. If the
Racks are hit with fighters still embarked, roll a D6-1 and that many
fighters manage to disengage from the racks and launch. Parasite racks
MAY be used on civilian transports. This was what they were developed
for in order to provide escorts for merchants in high risk areas. A
parasite rack may launch at any time IN ADDITION to any normal fighter
bay launches. They must be recovered within the normal constraints of
fighter recovery. Only Standard, Superiority or Heavy fighters may be
Parasite Racked as the racks do not provide support for specialized
weapon systems.

The cost is higher than a Bay mount because of the necessity of 
mooring the racks to the pressure hull in a way that is strong enough 
to avoid ripping them off at high accel. (and to avoid abuse) Also 
the one rack per 30 mass refers to the usable area of hull to place 
them. I think one mass per rack is perfectly acceptable given these 
restrictions.
