Some bloody good points above which I haven't considered in the past. I still hold that the idea isn't all as bad as its made out to be but there would be a number of significantly better ideas.
A fleet of dedicated warships utilising minimal crew and a host of drones (not originally linked to the main ship) would be a better idea. These would be complimented with cloaking technology and any other fresh of the drawing board tech.
The Prommie was the 1st of its class and would probably pave the way for more drone based assault vessels, even if the original idea was flawed.
