USS Liberty is a Sagan-class light explorer commanded by Captain Elara Galcyon. Assigned to Sirius Squadron, her primary duty is deep space exploration beyond the Federation’s Beta Quadrant frontier. Based out of the squadron’s headquarters, Gateway Station, Liberty ventures into former Romulan Star Empire territory within the Midgard Sector and beyond. There, even missions close to home are shrouded in mystery and challenge, with Starfleet only now able to enter these vast swathes of space mere light-years from the border. Exploring the remnants of the fallen Empire, Liberty faces new challenges every day as she charts, surveys, and analyses the region. More often than not, she operates independently from her squadron, though can conduct reconnaissance operations, provide scientific evaluation, and offer tactical support should the formation be deployed in its entirety.

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.

‘…repel even the lightest incursions from Sirius Squadron. The Federation is probing us, and instead of answering with discipline and deterrence, you offer delay and excuses. These are the tactics of scavengers, not soldiers. If the enemy moves unchallenged through our flanks, if they steal our [...]

Unit Commander’s log, Stardate 240204.14. Proxima’s secured. The ships which aren’t protecting her or fixing what the Vaadwaur broke – or who the Vaadwaur broke – are looking to take the next bite out of them. Which means we move into No Man’s Land, the dust belts and old relay [...]

It felt like he’d tried to drown himself in his shower a few dozen times since joining the Rooks. But this time, Rosewood thought, he might actually do it. Proxima IX still burned. The Vaadwaur consolidated their position at Toliman. And Drehm was still out there somewhere. There was very little [...]

‘I’ve read it, it’s incredible work.’ Elsa Lindgren’s face was exhausted on the small screen of Aryn’s PADD, but even on such a scale he could see the light of excitement in her eyes. ‘This could completely change the course of this campaign, Mac.’ ‘I’m sure someone else would [...]
