The Takemikazuchi was a trimaran naval vessel and the flagship of an Orb Union expeditionary fleet. It was built following the change in Orb's national defense strategy, shifting from an emphasis on security on the mainland and coastal areas to proactive defense by strengthening the pressure that can be exerted in the open sea. It is lightly armed with several 25mm anti-air gatling guns and anti-air missile launchers to intercept incoming missiles and enemy units that bypassed its escorts' defensive screen. Since it is a large aircraft carrier, it can carry a large number of MS on its two-level deck, with the upper deck being an angled flight deck, and is fitted with six linear catapults.
