Why modern warships keep getting bigger

Why does military equipment, especially warships, grow larger when other technology shrinks?

Warships must carry larger systems, aviation, fuel, sensors, protection, and crew support for long-range operations, all of which drive hull size upward.

Modern warships grow because the complete systems they carry demand more volume even when individual electronics become smaller. Larger helicopters, missiles, fuel loads, computers, support equipment, and provisions all accumulate inside a hull expected to operate farther from home. Crews may be smaller, but long deployments raise accommodation standards, while damage protection and damage-control arrangements consume additional space. Radar arrays also have to be mounted high, creating topweight and stability demands that push designers toward greater beam and length. Size growth is therefore a systems-integration and endurance problem rather than a simple pursuit of prestige.
