As an alternative to abandoning the land-based aegis missile defense system, Japan will build two new aegis warships, Defense Minister Shinzo Kishi said on the 9th. < / P > < p > in December 2017, the Japanese government decided to introduce two sets of land-based “Aegis” missile systems from the United States, which were originally planned to be located in Akita County in the northeast and Yamaguchi County in the West. However, on June 25 this year, then Defense Minister Taro Kono announced that Japan had abandoned the original plan of land-based “Aegis” deployment. One of the reasons was that the booster might fall into nearby residential areas after the anti missile interceptor was launched. < / P > < p > with the addition of two aegis ships, the number of aegis ships operated by Japan’s Maritime Self Defense Force will increase to 10, making it the force with the largest number of aegis ships except the U.S. Navy. < p > < p > on the same day, Kishino also announced that Japan intends to significantly increase the range of the 12 type land-based anti-ship missiles of the land self defense force, and develop them as “out of defense missiles” that can attack the enemy from beyond the range of the enemy’s missiles. Kyodo News Agency reported that this plan immediately caused some opposition party members to worry. They believe that Japan’s ability to do so will be contrary to Japan’s post-war peace constitution and its “exclusively defensive” policy.
