Why a battleship could not reproduce the Halifax Explosion

Could any battleship explode with the force of the munitions ship Mont-Blanc at Halifax?

No conventional battleship explosion is accepted as equivalent. A deliberately detonated nuclear weapon is a separate hypothetical case, since nearby conventional explosions would not automatically trigger it.

A conventional battleship magazine explosion is rejected as an equivalent to the Halifax Explosion. A nuclear weapon aboard an Iowa is raised as a hypothetical exception, but that requires a deliberate nuclear detonation. A nearby conventional explosion would not by itself trigger the nuclear weapon in the way proposed. The nuclear case therefore has different conditions from an accidental magazine loss.
