USS Tempest
Rhode Island-class • NCC-84705 • Liberty Science and Exploration Division • Sirius Expeditionary Squadron • Fourth Fleet • Managed by ADM Alexander Beckett
The USS Tempest NCC-84705 is a Rhode Island-class scout assigned to Sirius Squadron. Part of the squadron’s Science and Exploration Division, Tempest is a dedicated exploration and cultural investigations ship specialising in A&A (Anthropology and Archaeology) assignments. Under the command of seasoned scientist Captain Pentecost, the Tempest undertakes assignments of historical study, cultural exploration, and missions surrounding first contact, from preparation to execution to immediate aftermath. At a time when relations with Federation neighbours are strained, she is often part of collaborative research missions with allies, sharing Starfleet expertise to help expand cultural and historical understanding.
At present, much of her duties keep her on the borders with the Romulan Republic and the Klingon Empire, venturing into their space or beyond as needed, furthering Starfleet’s understanding of these rarely accessed regions of space, and the cultures that live there.
Sirius Expeditionary Squadron
Sirius Expeditionary Squadron is a unit centered around the Odyssey-class USS Sirius under the command of Commodore Matt Rourke. Sirius Squadron stands ready to deploy outside or on 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 main unit, organised around the Sirius herself, is an element of several powerful ships each able to take the lead or act independently depending on the mission’s needs. Deployed together, they are a supremely well-rounded and capable unit. Two additional divisions provide specialist support. The first, headed by the USS Redemption, acts as an operations element to provide engineering, humanitarian, or diplomatic services. The second, headed by the USS Liberty, fulfils dedicated exploratory or scientific missions. The divisions may deploy independently or in support of one another, depending on operational needs.

The Blackout was down. But the battle for Alpha Centauri wasn’t over. The bridge of the Endeavour was a storm barely held at bay. Emergency lights glowed hostile red across consoles, some of them cracked and sparking. Bulkheads groaned under strain. Officers moved with practiced urgency, the [...]
