Why 2030s surface combatants keep growing

A displacement question produces a mission-based estimate for future major, medium, and small surface combatants and explains why global endurance and active defenses drive size upward.

Question

What is a viable displacement for a surface warship in the 2030s?

Short answer

Mission drives the answer: about 15,000-16,000 tons for a major global combatant, 10,000 for a medium ship, and roughly 5,000 for a smaller one.

Notes

The estimate is roughly 15,000-16,000 tons for a major global surface combatant, around 10,000 tons for a medium one, and about 5,000 tons for a smaller ship. Worldwide deployment requires fuel, stores, sensors, weapons, power generation, and enough defensive systems to protect the investment. Several coastal ships may match one destroyer's aggregate tonnage, but they cannot automatically replace its endurance, survivability, or ability to operate across oceans.
