YOKOSUKA, Japan (Dec. 9, 2025) — A drill participant monitors a simulated injured person for low level radioactivity during an annual U.S.–Japan Joint Drill dry run. The drill, led by Commander, Submarine Group Seven, simulates a medical emergency aboard the nuclear-powered aircraft carrier USS George Washington (CVN 73), emphasizing the precedence of medical treatment. The low levels of radioactivity simulated as being present are about the same amount as the naturally occurring radioactivity found in a banana and are easily removed. Now in its 18th iteration, this U.S.-Japan Joint Drill demonstrates the integral coordination and cooperation between the U.S. Navy, Government of Japan, and city of Yokosuka that further supports the alliance between the two nations.
