The Star Army of Yamatai's First Fleet is a strong, experienced organization of ships and soldiers based at Yamatai. The 1st SF is closely associated with the Ketsurui Clan and Ketsurui Fleet Yards and is commanded by Kessaku Irim.

The First Fleet's mission is to:

• Fight the enemy in space combat.
• Protect Yamatai.

The First Fleet was formed in YE 22 as the Star Army of Yamatai's initial space fleet.

In YE 22, the Taisho Ketsurui Chiharu became First Fleet's commanding officer and the fleet was assigned the mission of Space Warfare¹⁾. The First Fleet was core participant of the Fourth Elysian War when it began in YE 23. In YE 24, the First Fleet was commanded by Taisho Kitsurugi Yui²⁾, then Chujo Ketsurui Mayame and was assigned the mission of Planetary Conquest³⁾. During the Second Draconian War, the First Fleet defended the Ralfaris system in the First Battle of Ralfaris. During the Second Battle of Ralfaris (in YE 25 in the Ralfaris system), the First Fleet's flagship, GSS Ketsurui Chiharu, was destroyed by Elysian forces, resulting in the death of Ketsurui Chiharu⁴⁾.

In YE 26, a major fleet restructuring reduced the amount of ships in the First Fleet from 3,336,847 starships to 3,210. In YE 29, a second major fleet size reduction occurred, changing the First Fleet into a Type 29 Fleet⁵⁾ consisting of 284 ships⁶⁾. It was commanded by Taisho Kessaku Irim.

In YE 33, the First Fleet was a major participant in Battle of Yamatai, defeating the forces of the NMX and defending the homeworld in the battle that turned the tide of the Second Mishhuvurthyar War⁷⁾.

In YE 41, the First Expeditionary Fleet was disbanded due to heavy losses in the Kuvexian War and the First Fleet received a number of ships and personnel from it, including the YSS Eucharis and YSS Kaiyō II. At the same time, the fleet was massively expanding to become the Star Army's “main” fleet for defense of the Kikyo Sector.

In YE 43, the First Fleet fought in the massive Battle Of Glimmergold. While the mission was completed, the fleet lost First Fleet lost 3,882 Super Eikan-class Heavy Cruiser and 478 Sharie-class Battleships to the Kuvexian Navy's ships, which outnumbered friendly forces by more than double.

In YE 44, first fleet helped rescue survivors during the Arrival of the Norians. Among many ships present were the YSS Battle Of Yamatai and YSS Resurgence. In YE 44.9, the First Fleet transferred 3,000 Eikan-class cruisers back to the Nataria Fleet Depot to get closer to complying with the maximum fleet size of 5,000 ships allowed by law. This left the fleet with 4,303 Eikan-class cruisers and 902 Sharie-class battleships, plus 11 Izanagi dreadnaughts and miscellaneous smaller craft.

In YE 45, the First Fleet started a major re-organization⁸⁾.
