As for the Iceni, I'm not sure whether Command knew about it or not, which sort of throws a kink into things, but not really. It actually sort of reinforces the above theory.
Command was quick to try and make pilots believe that Bosch wasn't on the station, and wanted to destroy it. They could be covering up an experimental new capital ship...or simply wanting Bosch to disappear, so there would be no chance of him becoming a martyr, and less chance of someone assuming control of the fleet. The hull also seems to be similar in composition to the Colossus', maybe indicating a next-generation ship?
This isn't supported by the fact that Command tells you to
investigate the asteroid. Although that could be explained as them being curious if Bosch had taken control of it, or because the weird grey-sphere things were actually engines and Bosch repositioned the installation so the GTVA wouldn't find it.
Maybe it was even another GTI ship, or a testbed for Colossus systems.
If Command didn't know, then it was probably done by Bosch to serve solely for the ETAK deal. (The Iceni's double-jump at the Knossos could've been facilitated by special jump capacitors) But of course all the NTF technicians would be told that it was a Neo-terran flagship, and giggle about how they'd pulled one on Command by using the beam weapons intended for retrofitting existing capital ships to build a cool new frigate.
Regardless, construction of the Iceni would require weapons and components. But with a retrofit, that wouldn't be as much of a problem.
Say you need beam cannons. Well, you classify the final destinations of such weaponry somewhat beyond the people taking them in-system. They know where they're going; obviously, shipyard/drydock locations would be fairly well know.
But they don't know exactly where. They can't track their exact path.
On the other side of things, you keep very accurate records of where things went. But when you want some beam cannons for the Iceni, you tell station A that station B got this beam cannon; station B, when it checks the same records, is told that Station A got the beam cannon.
The end result is that everyone is either in on the Iceni, and therefore gone through security checks, or thinks that somebody else got and used the beam cannon. The high volume of vessels being retrofitted would mean that tiny changes in the supplies wouldn't be as noticeable.
Whee.
