The closing questions ask which uncompleted postwar design was most dangerous, what two K3s might do to the treaty system, and how the United States and Japan might respond. K3's nine 18-inch guns are compared with Yamato-level firepower arriving decades early. The comparison applies only to gun power. K3 would not have Yamato's armour, so the two designs are not presented as equivalent ships. The caveat makes the analogy a measure of offensive scale rather than an inflated all-round comparison.

Yamato-level firepower, not Yamato-level protection
The closing comparison uses Yamato to convey the scale of K3's nine-gun battery while explicitly warning that the analogy does not extend to armour.
