Rescue Riker was a Lambda-class shuttle used by the Rebel Alliance during the Galactic Civil War.
Following a warning from Ordnance and Supply Command about a shortage of astromech droids, Rescue Riker was dispatched under escort from R-22 Spearheads to capture the BFF-1 bulk freighter Ars Opus which had broken down in the Rudrig system with a cargo of R2-series astromech droids.
Though the rescue effort came under attack from pirate transports and Y-wings, Red Squadron were able to hold off the pirates while the crew of the Rescue Riker boarded and captured the freighter. More R-22s from Blue Squadron arrived to escort the newly captured freighter and the pirates were unable to get close enough to prevent its escape.
