Seal Team transit/delivery vehicle intended for submarine insertion/extraction of covert ops personnel on the fly when aircraft delivery
operation is not an option due to high amount of overhead radar
sweep. very low signature? team boat can be slung underneath and moved rapidly to an area of operations.
this is why the dudes were in "civies" and didn't say a word about the craft or it's purpose. awesome machine. that is what we Rangers would do with it! hahahaha
