War Zone – The U.S. Navy wants to explore the idea of using small uncrewed surface vessels, or USVs, armed with Stinger missiles as a relatively low-cost additional layer of defense against various threats in the air and on the surface of the water. The service says it is particularly interested in the possibility of using the drone boats to help protect critical, but ever-more-vulnerable logistics vessels, as well as Marine contingents during future expeditionary and distributed operations.
