So missiles and drones don't have armor on their engine bell, it seems a whole formation of drones can get disabled by a nuke going off behind them, has anyone found a material composition that could survive a nuke or two?

Molybdenum is a good choice with high heat resistance, a bit dense though and not very light, im pretty sure it was a first choice for pusher plate design on Orion drives |

One tradeoff here is that running the rocket colder gives more safety margin for the parts to survive unexpected heat dumps without melting - but that has an obvious efficiency impact. I suppose you'd want to minimize the thermal expansion coefficient as well. |

Good point about running colder, though I suppose you don't have to design colder engines, just turn off the missile engines before nukes detonate.
