The Fifth Expeditionary Fleet of the Star Army of Yamatai is an expeditionary fleet devoted to the colonization and exploration of new Star Systems. It is under the command of Ketsurui-Motoyoshi Katsuko. The Fleet is responsible for the colonization and exploration of many star systems. Its first term of service was between YE 28 and YE 30. It was re-established in YE 44.7 by Taisho Ketsurui Yui and once again placed under the command of Ketsurui-Motoyoshi Katsuko. ¹⁾

The current motto is:

For the purpose of easy reference and Star Army Logistics, this is just a raw inventory of the fleet's assests.

The Main Expeditionary Battlegroup for the Fifth Expeditionary Fleet is called the Pioneer's Sword. The name gives a nod to the pioneering spirit of those colonists who are braving the mission to create colonies of the Yamatai Star Empire outside of the Kikyo Sector. The main battlegroup provides primary defense for the Colonization Initiative Alliance fleet and handles the role of fleet command for the other Expeditionary Strike Groups, Logistics Group, and Task Groups.

The Lorrheim Expeditionary Strike Group, is named after the YSS Lorrheim III and its series of proceeding starships. ¹³⁾ The group is under the command of Shôshô Motoyoshi-Ieyasu Taro. The Expeditionary Strike Group carries out missions under the directive of 5XFCOMM as required.

Named after the City of Sapporo on Jiyuu III, and the group's lead ship the YSS Sapporo. The Sapporo Expeditionary Strike Group serves as one of the at-ready combat strike groups within the Fifth Expeditionary Fleet.

The Fifth Expeditionary Fleet's Logistics group is the in-fleet operation of Star Army Logistics. It has everything from the fleet's freighters to the agricultural ships which support the food and water supply of the fleet. Like the Task Group they are often pulled from to create Task Forces for the fleet.

The Task Group is a group of ships used to create Task Forces as needed and combined with assets from other groups within the fleet.
