In 0 ABY just after the Battle of Yavin, it housed at least three Immobilizer 418 cruisers and four Imperial-class Star Destroyers. The drydock supplied the Outer Rim Imperial Fleet, and was only lightly defended.
The station was a stopover for Immobilizer cruisers that operated in the Outer Rim Territories. The drydock was the main target of Operation Ram's Head. In this operation, four Star Destroyers docked to the station were crippled by an automated CR90 corvette, the Ram's Head, sent on a ramming trajectory by the Rebel Alliance. The corvette was fitted with the Shield X technology which rendered the vessel nearly invincible to damage from the attack. The drydock itself was undamaged, but the attack was a humiliating setback for the Empire.
