USS Mercury
Obena-class • NCC-83010 • Liberty Science and Exploration Division • Sirius Expeditionary Squadron • Fourth Fleet • Managed by ADM Alexander Beckett
The USS Mercury is an Obena-class emissary. She forms a part of Sirius Squadron, where her role in exploration missions are focused on her capabilities as a diplomatic platform. Though favoured as a first contact specialist, she is also highly capable in building relationships with newer and developing contacts with the Federation, and expanding exploratory operations through diplomatic relationships. Under the command of the seasoned Captain Taviel Daragon, Mercury’s experienced crew take on a traditional approach of seeking out new civilisations and extending the warm hand of the Federation.
Sirius Expeditionary Squadron
Sirius Expeditionary Squadron is a unit centered around the Odyssey-class USS Sirius under the command of Commodore Matt Rourke and oversight of Director of Squadron Operations Vice Admiral Owen Morgan. Sirius Squadron stands ready to deploy outside or at the fringes of Federation territory at short notice to respond to emerging situations across the galaxy. With multiple versatile and powerful ships at its disposal, the squadron can operate independently and without support for extended periods, and is flexible enough to face a range of missions, including under volatile circumstances where objectives and conditions can quickly change. While this profile often leads Sirius Squadron to respond to geopolitical crises, the unit’s versatility make it equally suited emergent scientific investigations.
The squadron is based out of Gateway Station, in the Midgard Sector, which provides logistical support and operational and administrative leadership.
The HQ unit is organised around the Sirius herself, supported by her attached ship Alhabor. Four additional divisions provide specialist support:
- Endeavour Division: An administrative group including allied Romulan Republic and Klingon Empire assets assigned to the Fourth Fleet. The division exists to maintain unified oversight and communication, each ship answering directly to squadron command, rather than deploying as a task group.
- Liberty Science and Exploration Division: Conducts exploratory operations primarily beyond the Federation’s borders, expanding Starfleet’s understanding of unknown regions. When deployed alongside the squadron, these ships provide support through reconnaissance and advance operations.
- Memphis Division: Advances the squadron’s knowledge through sustained research, survey missions, and integrated intelligence work. Specialises in follow-up study and the detailed analysis of squadron-priority regions, organisations, or phenomena.
- Tannhäuser Operations and Outreach Division: Provides engineering, humanitarian, or diplomatic services primarily on the Federation frontier. This division is the most likely to be deployed as a unit and can be sent to whole regions in need, giving disaster relief or building infrastructure. When deployed alongside the squadron, these ships provide logistical support.
The divisions may deploy independently or in support of one another, depending on operational needs.
