Bismarck at Savo Island range

How would Bismarck fare if she replaced Chokai at Savo Island?

At roughly 5,300 meters, even Bismarck would be in extreme close combat where cruiser gunfire and torpedoes could inflict severe damage despite her heavier construction.

The 5,300-meter engagement distance is far inside the 18,000-yard range at which the British expected decisive capital-ship combat. At that distance, surprise, concentrated fire, and torpedoes matter enough that simply substituting a larger hull does not guarantee survival.
