The Platform was well armed, and was escorted by Sague, a a group of three Delta-class shuttles, as well as the IPV-1 System Patrol Craft Nemzet, the Y-wing Thunder, and the BFF-1 bulk freighter Renspecs. It was maintained by a repair crew which flew the Lambda-class T-4a shuttle Poltroon.
AZ 77 was originally a salvage yard, and was used to harbor criminals, smugglers, and, during the Galactic Civil War, a Rebel spy tracked by the Galactic Empire. The spy had a modified Corellian transport that could outrun the Empire's Assault Gunboats.
Because of the transports' speed, a TIE Defender, escorted by TIE Avengers, was deployed to capture the spy. The Platform launched the transports Lin, Ko, and Kaar, escorted by Rogue Squadron, but all three were disabled by the TIE Defender's ion cannons and tractor beam before they could escape into hyperspace. The Imperial-class Star Destroyer Glory arrived to oversee the Platform's capture of the Platform, and launched TIE Bombers and assault transports to disable AZ 77.
