Modern War Institute – The battle for twenty-first-century global supremacy will be decided across the volatile expanse of the Indo-Pacific. Characterized by vast oceans, dispersed island chains, and contested littorals, the rise of Chinese military power presents distinctive challenges to US military force projection and operational reach. Since World War II, American naval and air forces have typically led these maritime efforts on behalf of coalition teams. However, the changing operational environment—exemplified by recent area-denial campaigns in the Black Sea and the Persian Gulf—now present opportunities for land forces to counter adversary aggression in maritime settings with novel thinking and new approaches. The US Army, with emerging capabilities that promise to reimagine joint sea control, is now postured to enable revitalized strategic deterrence for the middle years of the twenty-first century.
