YSS Firebird NS-X1-213, was a Nozomi-class Scout built at Gemini Star Fortress in YE 29. She was heavily damaged in the Second Mishhuvurthyar War and reported as lost.

The Firebird emblem consists of the ship portrayed upon a nebula, with a gold circle with the ship's name and registry in it.

During the refit jalen_sune gave the ship the name Firebird, after the legendary bird. It seemed appropriate to him since the ship died in flames and was reborn.

• At the start of YE 35, blueberry-Chui assumed command of the ship.

• Sune took the YSS Firebird out on Operation Farsight

• Sune took the YSS Firebird out to rendezvous with the YSS Eucharis to meet with hanako to discuss what transpired with the Byakuren. After their first fold, a small problem with the drive was discovered and repaired by tetsuya_eiko. While the repairs were being made they received word to meet at Ether. Upon arriving at the system, the Firebird was met by forces of the alien navy which escorted the ship to the planet Ether. Where they met with the Eucharis.
• On Mended Wings

• In YE 34 jalen_sune acquired the ship as salvage. Originally he was going to use it as a test bed for some of his ideas but not use the ship in an active capacity. However, he changed his mind when an assignment he was preparing to take turned out to be undesirable. So he requested to be placed in command of the ship, so that he could get the major repair work he needed done more quickly. During the refit of the ship, Sune made a number of changes, some of these were due to newer equipment being available, such as escape pods. Other changes were made to support his experimental concepts.
