JAX high-calibre railgun for naval ships |

Like
all Japanese combatant ships now being constructed, the 27DD destroyers
will be powered by a COGLAG propulsion system (these two, as would be
explained again later, would represent a series of essential improvements
to the ships' space and power management and distribution in light of
the new weaponry that they will operate in the near future). On the more minor technical front, the new ships will also equip a new surface-search radar (the AN/SPQ-9B from Northrop Grumman), new anti-ship missiles, a multi-static sonar system, and an enhanced Aegis combat system that will offer better Cooperative Engagement Capability (CEC). |

Eventually, the Japanese MoD envisions their new AEGIS ships to be the
first operating platform of an indigenous naval railgun and laser point-defense
system that they are locally developing in Japan. The plan for the railgun
armament was outlined in their recently published FY2015 defense budget
report. The Japan Maritime Self-Defense Force (JMSDF) currently deploys two AEGIS detroyer classes: Four Kongo-class destroyers and two newer Atago class destroyers (plus four Akizuki class destroyers often called "Japanese AEGIS"). 2015 is the year 27 of Heisei era. This year (Heisei 27) the Japanese government has allocated the budget and formally begun the process of constructing and adding a new subclass of Aegis destroyers to its existing fleet of Kongo and Atago class AEGIS ships. This new subclass is officially called the "27DD". It is widely regarded as the second but a much improved batch of the JMSDF's Atago class destroyer (which in turn is an improvement of the Kongo class). The two 27DD vessels are expected to be commissioned in 2020 and 2021. |
