What studies have been done regarding the use of water to counter drones or drone swarms?

DSIAC was asked to identify studies regarding the use of water in C-UAS.  C-UAS platforms are divided into two primary areas:  detection and tracking systems and interdiction systems.  One example of interdiction C-UAS is a water projector or water cannon.  A water cannon was used at the 2016 Air Force Research Laboratory’s Commander’s Challenge to bring down a drone during a test exercise.  The U.S. Navy is using water cannons and water barrier lines to defend their platforms against high-speed, sea-skimming, antiship cruise missiles.  The wall of water provides a low-cost, universal defense system for Navy ships and has the potential to be applied to C-UAS.  Other water technology being utilized for fire fighting and antipiracy also has the potential for C-UAS utilization.
