Stealthy warship

If you happen to be in Swedish waters soon and think you are seeing a cross between a UFO and the Conehead family yacht, chances are it is a Visby-Class corvette, a stealthy craft that is reportedly “electronically undetectable at more than 8 miles in rough seas and at more than 13.5 miles in calm seas.” The corvette uses water jet propulsion for reduced draft operation.
