Solution

Japan has successfully test-fired a medium-caliber maritime electromagnetic railgun from an offshore platform as it continues to advance its defenses in the face of burgeoning regional security threats. For the test, the Japanese Maritime Self-Defense Force (JMSDF) collaborated with the Acquisition Technology & Logistics Agency (ATLA), a Japanese Ministry of Defense division. Learn Along:  A rudimentary, smaller 16mm railgun project was started by the agency’s Ground Systems Research Centre (GSRC) in 1990. Several years later, in 2016, the agency initiated what was an attempt to create a prototype with anti-air and anti-missile capabilities.
