GAS Engage
Class: Galaxy class heavy cruiser
Commanding Officer: Fleet Admiral Justin Gron, Gigerdian
Timocracy campaign
G.A.S. Engage was the command vessel in the attack on the Timocracy's homeworld. Fleet Admiral Justin Gron led the battle well, and the Engage survived the battle with negligible damages.
Lightness War
In the Lightness war, the first engagement that Justin led unfortunately led to a defeat, however several ships were able to escape, including the G.A.S. Engage. The second battle the Engage participated in was a victory, only the second against the Lightness aggressors by Gigerdian forces in the entire war. Subsequentially the Engage participated in several battles during the war.
After the war, the vessel's systems were drastically upgraded, and it was equipped with an organic armor system. It's believed that Justin Gron personally oversaw this modification process.
Defection
After the Lightness war the Engage mysteriously disappeared along with a fleet of several other ships commanded mostly by Gron; the 11th GA fleet. They were last seen in the Omirian system, where they disappeared near the planet Omirian 5. It is believed that this ship still exists and may even work as the main base of operations for the Resistance, however this cannot be confirmed at this point.
The G.A.S. Engage was a new prototype Galaxy class. When the Engage and her crew disappeared all the plans for this ship type disappeared with it, so no more vessels of this class were built or modified. However, currently the GA Research & Exploration division is designing a new model of the Galaxy class from scratch.
