Stennis (CVN 74) after a personnel exchange at sea with USS O'Kane (DDG 77).. The lines are used by deck department personnel to hold on to for safety, in case the RHIB boat falls. Stennis, as part of the John C. Stennis Carrier Strike Group, is currently conducting operations in support of Operation Iraqi Freedom and participating in Expeditionary Strike Force Exercise consisting of three Strike Groups; the John C.
