Armored survival pods for modern warships

Will armor return to modern warships?

Possibly as localized armored survival pods that protect crews and essential controls rather than the whole ship.

Designers could protect a compact command-and-survival citadel instead of armoring the entire hull. The concept resembles the protected crew spaces used in some target-ship conversions, where local armor preserved the people needed to control the vessel. After severe damage, the crew would retreat there and retain essential command and machinery controls. Such a citadel would preserve enough capability to fight the casualty and bring the ship home even after other combat systems failed.
