Data Recon Vessel
The only known usage of the Salvage Ship was during the Allied-Soviet joint strike team's attack on the Imperial Floating Fortress. During the first phase of the mission, Allied command dispatched a Salvage Ship to recover intelligence from a sunken Imperial Shogun Battleship. As the Salvage Ship was unarmed, the Allied-Soviet strike force had to protect it while it extracted the data.
The data the Salvage Ship recovered from the Shogun Battleship revealed that the Floating Fortress had a glaring weakness: its long-range Wave-Force Triguns relied on two Radar boats for long-range scanning and target-tracking. The destruction of those ships would prevent the Wave-Force cannons from firing, allowing the deployment of MCVs and the main strike force.
