No, it doesn't. Canon specifically allows planetary navies to build ships even without a shipyard[*] and doesn't specifiy the size of the shipyards used to qualify for a Class A starport rating. Trillion Credit Squadron muddles the picture a bit by making a class A rating a requirement, but on the other hand it specifically makes it possible to build a starship on a world with 100,000 people. 10,000 people if you just want spaceboats (And yes, I agree that those figures are ridiculous). And, really, if you do have the technology to manufacture the components, why shouldn't you be able to assemble them? How many (wet) shipyards are there on Earth today? The entire Earth? That's a ballpark figure for the number of pre-existing facilities a TL8 high-population world would have that could assemble small spaceships. TL 9+ worlds would have similar yards building grav cargo carriers (At higher TLs, grav vehicles are spacecraft). If the Imperium destroys them (and I agree that it can do that from orbit if it destroys the defenses first), it would still be possible to build secret yards.Canon suggests that shipbuilding is restricted to starports, and large ones at that.
Well, perhaps not. After all, if the Imperium destroys every manufacturer of grav vehicles, the world's infrastructure goes down the tubes. Instant tech level regression, not to mention population level reduction. After that, an interdiction seems pretty much superfluous.
[*] "Planetary Navies may procure ships at anywhere within the borders of their subsectors, or may construct the ships locally, using local resources, even if a shipyard is not present." [High Guard (p. 21 in the 1st edition; I don't have my 2nd edition handy)]
In TCS, yes. In mainstream CT, the shipbuilding capacity that gives Class A starport ratings has to be civilian shipbuilding. Military shipbuilding is evidently not involved at all.Furthermore, ports capable of shipbuilding are of strategic importance.
Any high-population world with a decent tech level has time, money, and resources. It may not have the incentive to develop such an industry if it has a neighbor with a well-developed insdustry of its own that it can buy from, but that's rather moot for an interdicted world.This suggests to me that a considerable investment of time, money and resources is required to develop a shipbuilding industry.
Then there's Plan B, offering to pay through the nose for ships built elsewhere.If such camouflage were possible, yes, but in the face of the above observation, I'm not convinced it is possible.
This is an unsupported assumption. How about an underwater facility, for example? Or deep inside a mountain?You can begin to build ships, but as soon as you do, your attempts are discovered and destroyed from orbit.
We are? Good.We're in agreement that a lone patrol ship isn't being discussed.
For a world with pop 5, a single patrol ship would be more than enough. But then, with a population of that size, there are any number of 'boots on the ground' solutions that are practical. There might not even be a problem in the first place. Just set up a colony of settlers on the other hemisphere, build a starport there, and ignore the religious nuts on the other continent.Depends on the strength of the interdicted world. For a world under pop 5 with effectively no air/space military capability, a single monitor with a flight of fighters might be all that's necessary.
You won't get any argument from me on that score. As I said earlier, the Imperium can interdict any world it wants to. Just not always on the cheap.OTOH, a pop 9+ world with the capability to produce or import a significant space navy might need a significantly sized task force to successfully interdict it.
