Defense Advanced Research Projects Agency (DARPA) announces the availability of their free anti-submarine warfare game, which was developed by military simulation game specialists Sonalysts based on their Dangerous Waters. This is actually a research tool of sorts, and players can choose to upload the outcomes of their games to DARPA for analysis. Word is:

This software has been written to simulate actual evasion techniques used by submarines, challenging each player to track them successfully. Your tracking vessel is not the only ship at sea, so you’ll need to safely navigate among commercial shipping traffic as you attempt to track the submarine, whose driver has some tricks up his sleeve. You will earn points as you complete mission objectives, and will have the opportunity to see how you rank against the competition on DARPA’s leaderboard page. [https://actuv.darpa.mil/LeaderBoard.aspx] You can also share your experiences and insights from playing the simulator with others.

As you complete each scenario in the simulation, you may submit your tracking tactics to DARPA for analysis. DARPA will select the best tactics and build them into the ACTUV prototype.
