Ars says the companies pitching Golden Dome’s orbital interceptors are still very much in the “maybe someday” phase, with cost and scaling doing most of the reality-checking.

Yeah “maybe someday” feels right here — it’s like trying to build a roof that has to catch raindrops while the roof is moving and the raindrops are accelerating. even if one interceptor works, scaling it to real coverage sounds like an insane amount of hardware and launches, so cost just eats the idea alive.

That “moving roof catching raindrops” thing is dead-on, and the part that always fries my brain is the clock. Up there, being off by a fraction of a second isn’t “a little late,” it’s “you’re not even in the same zip code,” because everything’s hauling and the geometry changes constantly.

And yeah, proving one intercept is like landing one trick shot… coverage is the brutal part. You’re suddenly buying not just interceptors, but the whole boring fleet stuff: enough orbits to be in the right place, spares for failures, replenishment launches, and the ops overhead to keep it all coordinated. Cost just bulldozes it.
