iRobot ProprietaryCNO Guidance for 2011*Navy will invest in UUV Endurance“Way Ahead: • We will pursue unmanned systems as an integrated part of our force, ensuring that the move to ‘unmanned’ truly reduces personnel requirements. •We will develop a long-endurance, safe power source for UUVs” *Executing the Maritime Strategy” (1 October 2010 )“Roughead says he wants to spend about 50% of available UUV researchand development money on improving their endurance. Ultimately hewould like to see 3-4 weeks of endurance and reserve power for somehigher-speed maneuvers and to handle strong underwater currents.” Aviation Week, 8-25-2010: CNO Speaks about Unmanned Vehicles at AUVSI

iRobot ProprietaryWhy wait for a breakthrough in batteryendurance to achieve unmannedunderwater goals?

iRobot ProprietaryADAPS Alternative approach to underwater vehicle energy limits

iRobot ProprietaryFuture air deployment of AUV’s near targets of interest willreduce transit time, improves tactical utility and relevance

iRobot ProprietaryReduced turnaround time on AUV missions is enabled bynew digital data link relays deployed on maritime UAV’sADAPS passively loitering on surface to establish data link to relaycollected data and receive commands from remote control site
