Recent Video by the YouTube Channel "Not What You Think" titled "The Water Shield for Modern Warships"

Recently the YouTube Channel "Not What You Think" Posted a Video on this concept. ( Link Here )
Specifically on "Countermeasure Washdown System"
I didn't know of that keyword, and the video showed some footage i hadn't seen before, notably modern warships testing their countermeasure washdown systems
I guess YouTube videos can't be linked On-Wiki, but utilizing it as a starting point to find primary sources and public domain footage etc may be of use
