In this photo file, the guided-missile destroyer USS John Paul Jones (DDG 53) steams into position during an Expeditionary Strike Force (ESF) exercise, March 16, 2008. The Nimitz Carrier Strike Group (CSG) recently participated in an ESF with the Essex (LHD 2) Expeditionary Strike Group (ESG). The ESF exercise was designed to test the ability of the Strike Groups to plan and conduct multi-task force operations across a broad spectrum of naval disciplines and to refresh skills in completing complex missions that require capabilities that are broader in scope than the individual Strike Groups can provide alone.
