From Island Hopping to Autonomous Defense: Pete Ellis, Sea Power, and the Case for Defensive USV Integration
Major Earl Hancock “Pete” Ellis, U.S. Marine Corps, strategist whose vision of forward bases and maritime sustainment shaped modern amphibious warfare. In the early decades of the twentieth century, long before radar, satellites, or unmanned systems, a Marine Corps officer looked across the Pacific and saw a future war taking shape. Major Earl Hancock “Pete” Ellis, remembered most often for his influence on amphibious doctrine, was not captivated by islands themselves.

Ellis’s work begins from a simple premise: naval fleets do not operate in isolation.
