 Welcome to All Hands Update, here's what's happening around your Navy. Secretary of the Navy Ray Mabus likely delivered his final address as SecNAB at the 29th Annual Surface Navy Association Symposium in Crystal City, Virginia. Mabus addressed surface warfare community members highlighting all the Navy has achieved during his more than seven years in office, while emphasizing the importance of fleet growth and alternative energy use. Defense Advanced Research Projects Agency, or DARPA's, Tactical Undersea Network Architecture recently completed its initial phase. Successfully developing concepts and technologies aimed at restoring connectivity for U.S. forces when traditional tactical networks are knocked offline or otherwise unavailable. TUNA seeks to develop and demonstrate optical fiber-based technology options and designs to temporarily restore radio frequency tactical data networks in a contested environment via an undersea optical fiber backbone.
