The Builder-Class YardShip is a Auxilary type WarShip used to support active naval assets belonging to the Star League. Created by 2ndAcr, the ship was designed and produced in the Fate Can Be Cruel/Hegemony AU's Terran Hegemony (Periphery).

The ship came about as orphaned Star League forces operating in the Outworlds Alliance formed alliance with worlds in forgotten by the Alliance in further reaches of the Nation's colonial region and needed to relieve stress placed on their sole Newgarge-Class YardShip. Conceived by Rear Admiral Delvaney in 2775, the Builder Class was intended less costly alternative to the bigger Newgarge, while still being able handle majority tasks needed within the Hegemony's newest claimed space without need for escort.[2]

Starting to enter service in 2776, these ships would go on to serve the Terran Hegemony (in Exile) turn the Hegemony in years to come helping build budding new nation in deep periphery.

With only a maximum thrust of 3, the ships are not terribly fast, nor well armored with exception of against light forces. The ship's 270 tons of Ferro-Aluminum Armor enough armor handle minor attacks from capital grade weapons.

While not frontline combatant, the ship mounts number of Class 35 Naval Lasers; two forward sides, 3 each Broadside, and three in it's aft firing arc. Supporting the ship in anti-aerospace fighter defense and point defense, is large number of Large and Small Pulse Lasers in all but it's front firing arcs.

For the ship's primary mission of the ship, ship utilizes 1 million ton weight capable unpressurized Repair facility and drydock. For various job, the ship's yard works, are able to access 165,754 tons Cargo spaces for supplies and other materials.
