Knights of Sidonia PMC

The name and origin of the Knights of Sidonia Private Military Corporation (KOS PMC) would not become publicly known until 2942. Its roots, however, trace back to a classified contingency initiative devised by the United Empire of Earth (UEE) government—one of hundreds of private militia frameworks prepared as a last-resort measure.

 

This contingency effort was formed by the UEE Navy (UEEN) [CLASSIFIED] Staff of Fleets under the codename Project Golfland, a long-term program cultivated for no less than four years prior to any potential deployment.

2940

The primary objective of Project Golfland was to equip UEE citizens with the tools, training, and logistical support required to raise private militias, should formal UEE military efforts prove insufficient during the escalating war against the Vanduul and ongoing counter-insurgency operations.

​

In 2940, several senior naval officers were assigned to the program alongside hundreds of other UEEN personnel. These officers were placed in command of capital vessels ranging from RSI Polaris corvettes to Aegis Javelin-class destroyers, using these ships as mobile command platforms to protect, organize, and guide emerging civilian militias toward operational readiness and combat effectiveness.

2942

Well into 2942, the UEES Sidonia, a Javelin-class destroyer, was put to the test—an event that would ultimately forge both the resolve of her crew and the legacy of the organization that would follow.

​

While on patrol along the borders of the Ellis System, the Sidonia was caught unaware by a scouting Vanduul naval brigade, which launched a surprise attack from over 100 kilometers away. The destroyer was alerted to the enemy’s presence only after a Vanduul torpedo struck her communications array, crippling her ability to issue a distress call.

​

Alone and outnumbered, the Sidonia was unable to mount a sustained defense. She immediately set course for the nearest allied forces, attempting to use nearby celestial bodies for cover. As no moons orbited Kampos (Ellis IV), the destroyer diverted toward Ellis 5A, a moon of Noble (Ellis V).

​

Throughout the retreat, Vanduul forces launched repeated attack waves. Each assault was met with disciplined defensive fire, crippling numerous bombers and fighters. While these actions slowed the enemy advance, the Vanduul capital ships steadily closed the distance, their main batteries training on the fleeing destroyer as they entered effective weapons range.

​

Upon arrival at Ellis 5A, the Sidonia dropped into low orbit, at times flying less than 200 meters above the moon’s surface. The ship used the moon’s low gravity and terrain to its advantage, forcing the Vanduul fleet to attack from above. This allowed the Sidonia to redirect power to her port, starboard, and dorsal batteries, maximizing defensive coverage.

​

During this maneuver, the Sidonia detected a small militia outpost on the surface—completely unaware of the approaching destroyer and the pursuing Vanduul fleet. An observation post located 25 kilometers from the outpost detected the Sidonia’s arrival and immediately launched a distress beacon through the outpost’s limited launch systems, though no return communications were possible due to the installation’s isolation.

​

Tragically, a Vanduul Void Bomber torpedo struck two of the Sidonia’s engines, severely compromising her maneuverability. In response, the crew rapidly disabled all ventral weapon systems and lower shielding, reallocating power to the remaining engines and thrusters. Despite these efforts, the destroyer could not maintain her trajectory.

​

The decision was made to bring the Sidonia down directly in front of the militia outpost.

​

With her remaining guns blazing, the Sidonia executed a controlled crash-landing several kilometers from the installation, establishing a protective dome of fire around it. The impact caused irreparable damage to the ship’s forward torpedo launchers, rendering her primary offensive weapon systems permanently inoperable.

​

What followed would cement the name “Knights of Sidonia.”

​

For the next sixteen hours, militia personnel conducted repeated supply convoys under constant fire, hauling ammunition and power cells to sustain the Sidonia’s defensive batteries. Each convoy suffered losses, yet the resolve of the militia did not waver.

​

Upon the arrival of a UEEN relief fleet, the Vanduul forces disengaged and retreated back into Vanduul space.

​

The combined actions of the Sidonia’s crew and the militia defenders earned them their enduring title—the Knights who defended their keep against a brutal and unrelenting enemy.

​

Despite numerous recovery attempts, the UEES Sidonia was ultimately deemed unsalvageable and decommissioned on site. Her remaining components were stripped for reuse, leaving behind her scarred hull as a lasting reminder of the Vanduul threat and their reach into UEE territory.

​
 

2943

Despite the loss of their flagship, the unofficial Knights of Sidonia militia was replenished in 2943 with the assignment of a successive Javelin-class destroyer. With this reinforcement, the militia formally commissioned their flagship and continued operating as a capable and increasingly vital asset to the UEE.
 

2944

The year 2944 marked the conclusion of Project Golfland and the official commissioning of several hundred militias and private military corporations. Among them, the Knights of Sidonia PMC was formally recognized, with its flagship rechristened as the KOSS Sidonia.

​

Though now a fully civilian-managed organization, many of KOS’s members trace their origins to earlier engagements—most notably the events of 2942—bringing with them invaluable combat experience and institutional knowledge.

​

The Knights of Sidonia continue to operate from the Ellis System to this day, with plans underway to establish a permanent KOS Headquarters within the system.
