Re: Nuclear s(n)ubs
A warship may be targeted by terrorists. Every sailboat, fishing boat, jetski is a potential threat. Their protocol is based on the overall threat of an attack not so much how frendly the nearby boats look. If the warship sees all of them yielding to the 500 yd perimeter and veering away rather than engaging with them would make it overall safer. Last thing we want is to help terrorists figure out how to get our warships to let their guard down by acting like a recreational boater.
