170710-N-ZW825-122 CORAL SEA (July 10, 2017) The amphibious transport dock ship USS Green Bay (LPD 20), right, is underway alongside the Arleigh Burke-class guided-missile destroyer USS Sterett (DDG 104) before a replenishment-at-sea during Talisman Saber 17. Sterett, part of a combined U.S., Australia and New Zealand expeditionary strike group (ESG), is undergoing a series of scenarios that will increase proficiency defending the ESG against blue-water threats so amphibious forces can launch Marine forces ashore in the littorals. Talisman Saber is a biennial U.S.-Australia bilateral exercise held off the coast of Australia meant to achieve interoperability and strengthen the U.S.-Australia alliance.
