Stalker

The Stalker was an Imperial-class Star Destroyer of the Imperial Navy. Stalker was responsible for deploying Viper probe droids across the galaxy in hyperdrive pods in an attempt to discover the Rebel base. One of these probes reached the ice planet Hoth, the location of Echo Base. The discovery of the base resulted in an Imperial victory.
