The deployment included missions linked to tensions involving Iran and other regional flashpoints, but it has also reignited debate over mounting pressure on America's 11-carrier fleet. Longer deployments can increase crew fatigue, accelerate wear on critical systems and strain maintenance schedules. Is this a remarkable display of naval endurance—or a warning sign for U.S. military readiness?
