I just don't see how the fuel costs of getting things up to space winning out unless production is located up there. especially since rocket launches tend to be extremely static.

More dangerously, I think that would inevitably lead to space being the battlefield. Since that area doesn't need any more shrapnel orbiting at 17,500 mph; it seems an idea best left to the drawing board. The cleanup required will make clearing mine fields seem like dusting the living room.

Starship's in theory targeting something like a million bucks in fuel for a launch. For a military that spends more than that on individual missiles, that's peanuts.

Starship is also in theory targetting to reach Mars in 2022.

There's an unavoidable physical cap here.

It's fueled with methane and oxygen, and its size is known.

It can't be, say, $50m/flight in fuel for the same reason a 747's flight can't be; there's not enough space for that much fuel.

[tsimionescu]

Sure, but that's true of Saturn V as well, and of Falcon 9, and Soyuz and any other rocket you want. That didn't make space deployment a viable military strategy so far, and I think we should be skeptical of any such claim about Starship.

Also, fuel is just part of the cost of a rocket.

Sure. But if you blew up a 747 at the end of every trip, it'd be a small part of the total cost, not a major part.

Starship's reusability makes it very clearly not like the other examples you cite, yeah? There are lots of scenarios where the US government would pay, say, $10M to deliver a payload somewhere fast, but not $250M.

Co-development of the SpaceX Tardis makes deadlines irrelevant.

The prospect of cleanup duty has never stopped anyone at war. Fields of landmines maiming children for decades, unexploded ordinance in cities, etc etc.

Near earth orbit will be a field of debris until gravity takes over.
