@YourNetworkIsHaunted Ukraine is building its missiles well enough even now, it has expertise, skilled workers, etc. Ever heard of Mriya, Antonov, etc?
Also, ironically, it was a major supplier of the Russian Air Forces, and it maintained Russian rockets until recently.
@cstross@V0ldek New motors? Cruise missiles use turbofans, just like planes, unlike rockets. So they don't get old fast, probably last 30 years just fine.
And, well, just build them in Ukraine, and shoot them the day they are made...
