It would be another leg in the triad—presumably obsoleting strategic bombers for most potential scenarios. All the legs have trade-offs, which is why you want more than one: Silos are immobile. Bombers are slow, limited-range and vulnerable. Submarines have to hide and thus are difficult to keep in touch with reliably. They’re also damn complicated and may have systemic vulnerabilities we don’t fully understand. A long-orbit, large-payload space plane brings some interesting new trade-offs to the strategic nuclear game, though who knows if that’s actually how it might be used.

> Silos are immobile. But mobile launchers aren't. Russia and China use those, but we don't. > presumably obsoleting strategic bombers We'd have to have hundreds of warheads in orbit at all times to obsolete strategic bombers. If the x-37b is to be used for carrying (or deploying) orbital nukes, then at least for now it has to be a very few nukes. Re-entry vehicles are visible because they glow white hot as they re-enter, so while surprising (because there is no boost phase to detect, and because the detectable flight time will be less than half that of an ICBM) they will not provide enough plausible deniability to be worth using at all. This is why I doubt the x-37b is being used to carry nukes.

There is exactly one country who would have any hope of even achieving MAD in a nuclear exchange, and that number isn't going up any time soon. I don't know that I see any reason to add legs here.

  Russia, China, and the U.S. all have MAD capabilities.

  Without a deeper analysis, that’s an argument to scuttle our missile subs, too. I mean, it’s an argument to be had, but the advantages of a dominant multi-modal nuclear arsenal go beyond binary assurance of mutual destruction in total war—today. You’re the Chinese premiere in 2030 or 2040 choosing whether to try to match US strategic capability. How many chips that requires in the pot for a call makes a difference in that calculation.

  Having the capacity to hold & deliver live warheads doesn’t mean it’s exercising that capability today. Anyway this is all incredibly speculative. Nobody knows the real strategic purposes of this thing.

Bombers are long obsolete. When is the last time someone used a bomber? Missiles/ rockets have already replaced their functionality

  F-35 still carries bombs as well. And the USA recently revealed the B21 stealth bomber.

    They struck targets what makes you think they flew an F35 over them and dropped a bomb?
