There is little question that world militaries see the value of unmanned systems to complement their manned counterparts. The wars in Iraq and Afghanistan accelerated the development of unmanned aerial systems and unmanned ground systems to meet urgent operational needs. Now, there is increasing interest in unmanned surface systems, resulting in their placement on an accelerated development path.
