I'm not a rocket scientist, but I think thrust is pretty constant at that scale. That's why they start, spool up, then release from cradle.
Vs something like a Polaris SLBM that has a much more variable guidance problem
It'd be curious to see how early ICBM and SLBM guidance systems differ.
- kens 2y agoI haven't looked at submarine systems in detail, but my understanding is that the big problem is that an ICBM knows where it's starting, but the submarine travels. So submarines have super-accurate inertial navigation systems on board to determine their position.

Which way is it rotated? Is it inclined off vertical?
