You're making unnecessary assumptions. For one thing, they probably already have the necessary designs, they built it once. For another, they certainly have the specifications already. They even have practice rebuilding infrastructure from scratch from the Basilisk raid. It wouldn't surprise me if they'd had contingency design plans for the major stations in a Case Zulu folder somewhere.kzt wrote:How long does it take to build a SD that you have plan for and have a validated design and equipment already optimized. 18 months at best, with a highly experienced crew serially building just that ship, with all the parts needed already available.
So now you want to build something at least an order of magnitude bigger, without any existing plans. And it needs to accommodate a whole range of massive factory equipment that as yet needs to be built. How long do you think it will take? Hell, how long will the design process take? Which can't even start until after you put together the specifications for what it is supposed to do and accommodate. Then you need to order all the long lead-time parts.
The key to rebuilding the infrastructure is not to consider a single project but as a whole mess of smaller projects that use off the shelf equipment as much as possible. As you pointed out, there's no time to design anything.
Which isn't a plus. Essentially there is no way to get the money back if they tell you they don't want to pay or realize that can't pay. Since they really badly need the infrastructure built they have every reason to be optimistic on how they can pay it back. And if they can't or decide they won't you will do what? Stamp you feet and hold your breath until you turn blue?
Unless the lender is a Solarian transteller, there's pretty much no chance of them using military force to ensure repayment regardless of who they lend to. The biggest risk of lending money to Manticore (for the last twenty years and the foreseeable future) is that the polity will cease to exist. Not to mention there no evidence Manticore is in the habit of default on their debt, nor any particular need for them to do so.
