     For Naval warship fans.

      A new British nuclear sub just being launched for sea trials...the HMS Ambush...doesn't need a periscope.

      Its sonar is so sensitive...it can hear vessels moving 3,000 miles away.
      Armed with 38 Tomahawk missiles...the $1.6 billion nuclear reactor sub can cruise non-stop...for 25 years...and travel up to 500 miles per day!
