Why this matters
Why now

The increased geopolitical competition, technological advancements in maritime domain awareness, and nations' growing ambition to project power over larger sea areas are driving this evolution in sea control.

Why it’s important

A strategic reader should care because evolving sea control dynamics directly impact global trade routes, resource access, and the balance of power, forcing navies to adapt to new operational realities.

What changes

Navies are now expected to exert greater and more persistent control over broader ocean expanses, requiring new strategies and technologies beyond traditional naval warfare.
