The Navy League’s on-line magazine “Seapower” reports that,

“DHS S&T teamed up with the Coast Guard, University of Southern Mississippi (USM), the U.S. Naval Research Laboratory (NRL), the Applied Research Laboratory (ARL) at Penn State, Ocean Aero, Inc., Cherokee Nation Strategic Programs (CNSP), and the Homeland Security Systems Engineering and Development Institute (HSSEDI), to develop, acquire, evaluate, and test specialized, environmentally powered (wind and solar), multi-mission capable, unmanned surface and underwater vessels.”

This looks interesting and the fact that the Department is involved makes it doubly promising.
