Theta Fleet formed on December 10, 2009 when the USS Endeavor and the USS Orion (now USS Calypso) left Obsidian Fleet to create a more relaxed and friendly place to sim. They were joined by Starbase Typhon, a new sim, and formed the core fleet.
The Fleet has seen minor changes in its leadership structure with Charlene Harmon (Kathryn Burke) who joined Theta Fleet in 2010 as Deputy Commander of the Fleet becoming Commander of Theta Fleet in 2011 by a unanimous decision. Phil (Aric Barclay) became Deputy Commander in 2011, and Raymond Dale (Veruka Kitan) was promoted to Deputy Commander in 2021.
Theta Fleet has undergone an overhaul on recent years to bring the Fleet itself into the 2020s, retiring the old simming practices of regimented fleet constituon, replacing it with a repurposed fleet charter, switching from monthly fleet meetings to open fleet socials. At its heart, Theta Fleet has always been about the players and building a community of creative collaboration.
Now, the fleet continues onward as a beacon of hope and often becoming a sanctuary for COs and players seeking refuge from fleet politics. It currently is home to over forty unique games including: nova based, forum, Discord operated simming, and live roleplay.
Theta Fleet revieved the honor of being a 2018 Simming Prize laurette. In addition to the fleet's honor, its COs and Sims have accumulated dozens of accolades from organizations such as Ongoing Worlds' Tournament of Sims.
