Why Maya's upgrades suit a two-ship Japanese buy

The United States gets more aggregate force from a 47-ship Arleigh Burke Flight IIA program than it would from fewer, more expensive Maya-like hulls. Japan could pay for costly technology earlier because it wanted the best attainable capability in only two ships. Some of that technology later became affordable for Flight III Burkes as prices fell, so the balance between capability and quantity changed with technical maturity. Weapons, sensors, crewing, and operating concepts increasingly determine a warship's internal systems architecture. Designers then shape the hull and support spaces around those requirements.
