The Defense Advanced Research Projects Agency (DARPA) is soliciting innovative research proposals in the area of distributed unmanned sensors and systems for maritime applications. Proposed research should investigate innovative approaches that enable revolutionary advances in science, devices, or systems. Specifically excluded is research that primarily results in evolutionary improvements to the existing state of practice. Details are contained in the attached Broad Agency Announcement (BAA) DARPA-BAA-13-17.Basically DARPA wants to have a magazine of unmanned systems that can be called upon and deployed. It is worth reading the detailed announcement at the link if you want to get your juices flowing.
As long as we are dreaming up ways to do cool things, I'd like a box of 36 Tomahawk missiles and 12 Harpoon missiles that can be towed into position by a submarine and left suspended at around 100 meters depth until called upon.
