Not every relativistic projectile will be broken. And every projectile is relativistic, more or less.
Trying to escape from the Ehrenfest’s paradox with saying—this starship breaks anyway—has a long tradition. Max Born invented that “exit”.
Even if one advocates the breaking down of any torus which is moving/rotating relative to a stationary observer, he must explain why it breaks. And to explain the asymmetry created with this breakdown. Which internal/external forces caused it?
Resolving MM paradox with the Relativity created another trouble. Back to the drawing board!
Pretending that all is well is a regrettable attitude.

Each piece of the ring is longer as measured by an inertial observer comoving
We, at this problem, don’t care for a “comoving” inertial observer. We care for the stationary observer in the center, who first see stationary and then rotating torus, which should contract. But only in the direction of moving.
Can you see why the rope in my example would break or stretch, even if we’re moving it very very slowly?
Your example isn’t relevant for this discussion.
Why not?
Look!

Why wouldn’t that also apply to my rope example?
