The U.S. Navy’s George Washington Carrier Strike Group is joining in exercise Talisman Sabre, contributing thousands of sailors to the largest iteration of the multilateral exercise off the coast of Australia in the CSG’s first major international exercise since returning to Japan.

The event began with live-fire exercises, including Australia’s first use of U.S.-supplied HIMARS rocket systems.

Exercise Talisman Sabre, which began its eleventh iteration on 13 July, has over 30,000 personnel from 19 countries taking part, including the Pacific.
