The U.S. Naval force presented one of its newest ships, the USS Zumwalt, which is the most military advanced destroyer in the sea. The new destroyer has staggering capacities, including low radar perceivability, lasers, and is armed with rail guns that were tested in real life in 2016. The ship costed around $3 billion. Named after Admiral Elmo “Bud” Zumwalt, the warship features innovations and a stealthy shape intended to limit its perceivability on enemy radar and has reduced the crew number. Rail guns fire a shot at six or seven times the speed of sound – enough speed to bring serious harm. The Navy considers them to be supplanting or supplementing outdated weapons.
