Riirdo was a Cargo ferry used by pirates during the Galactic Civil War.

The Cargo ferry, along with Filcher under escort of escort shuttles Devil had stolen two containers of munitions from an Imperial armory. They arranged a rendezvous with a pair of Rebel ferries Redbill and Wippet, which would have Y-wings as their own escorts.

However, Imperial Assault Gunboats and two Stormtrooper transports arrived to reclaim the munitions and arrest the pirates. The pirates escorts were destroyed and both ferries were disabled, the transports boarded Filcher and Riirdo seized the cargo and arrested the crews. The ferries were destroyed afterwards. The event was recorded and recreated for the Combat chamber to train future pilots such as Maarek Stele
