The USS George Washington and its embarked carrier air wing conducted a sinking exercise (SINKEX) in the Philippine Sea on June 29, 2026, sending a decommissioned amphibious assault ship to the ocean floor. The operation, reported by The War Zone, marks a routine but significant demonstration of U.S. naval strike capabilities in a strategically contested region.
SINKEX drills serve to validate the effectiveness of anti-ship weapons and tactics against large, moving targets, reinforcing the Navy's ability to deny adversaries use of the seas. The choice of a decommissioned amphib as the target underscores the service's focus on realistic training against vessel types that potential rivals might field.
While such exercises are standard for maintaining readiness, the location in the Philippine Sea carries added geopolitical weight. The area lies near critical SLOCs and is adjacent to the South China Sea, where Beijing has been expanding its maritime presence. The drill signals U.S. commitment to regional allies like the Philippines without directly naming any adversary.
Cost figures for the exercise itself were not disclosed, but sinking retired hulls typically avoids the expense of full dismantlement. The Navy budget for training and live-fire events falls under operations and maintenance accounts, which annually total in the tens of billions. No new procurement is tied to this specific event.
Some analysts caution that SINKEX data may be incomplete since target ships lack active defenses and crew, limiting the exercise's tactical fidelity. Environmental groups also criticize such drills for potential pollution from sunken vessels, though the Navy states they follow legal protocols to remove hazardous materials beforehand.
