A U.S. Naval Ship in the Sea of Japan

The pentagon recently released a statement saying that the U.S. navy ship USS Curtis Wilbur was deployed to the Sea of Japan, which is the coastal side of North Korea. The ship was deployed in order to protect U.S. troops in the area and the U.S. allies. It was also deployed to begin the missile defense system. The ship includes missiles that would be able to shoot down and destroy other long range missiles that would possibly come from North Korea. It also will eventually be able to conduct long range monitering and tracking of enemy missiles. This new missle defense system could posssibly cost 50 billion dollars over the next 5 years.
