World War II can be understood as more favorable to battlecruiser qualities than World War I. Fleets needed speed and operational mobility across larger theaters, while aircraft increasingly delivered the principal plunging attack. Typical bombs were lighter than battleship shells, changing the balance between deck protection, speed, and useful reach. This does not erase the vulnerability of lightly protected capital ships, but it explains why fast capital ships and carrier escorts remained strategically valuable. The comparison encourages viewers to judge a design against the threats and missions of its own war.

Speed and mobility became even more valuable when aircraft-delivered bombs replaced battleship shells as the dominant plunging threat.
