It's the radars really for destroyers. The bridge is not actually where the ship is run during combat.
There is a room called the combat information center, that's where the ship is run from during combat, and that is behind armor, even in modern warships.
Additionally ships are separated into semi independent zones, that can take control of the ship, and continue fighting even if the rest of the ship is on fire.
The real liabilities are the radars, and the rest of the sensors in surface combat ships and the airplanes on deck in the case of aircraft carriers. Aircraft carriers in general are heavily armored compared to other modern warships and it takes a significant amount of firepower to even disable them much less sink them.
That's great if you're in a shallow anchorage (average depth: 45 feet). Less so if you sink in the Arabian sea and you're under fire during the refloating process.
I also suspect modern ships are a little more sensitive to complete immersion.
> In May 2019, the Minister of Defense was presented with a report from Defense Material which concluded that a possible repair would cost 12–14 billion and take more than five years. The cost of purchasing a new corresponding vessel was estimated at NOK 11–13 billion, with a completion time of just over five years.
