BATH, Maine — The future USS Zumwalt is so stealthy that it’ll go to sea with reflective material that can be hoisted to make it more visible to other ships. The Navy destroyer is designed to look like a much smaller vessel on radar, and it lived up to its billing during recent builder trials. Lawrence Pye, a lobsterman, told The Associated Press that on his radar screen the 610-foot ship looked like a 40- to 50-foot fishing boat.
