RVR

In the Thunder Force series, the RVR (Refined "Vasteel" Replica) is a series of new starfighters featured in Thunder Force V and Thunder Force VI. With the discovery of Vasteel, mankind uncovered its secrets through the process of reverse-engineering and created these fighters as their last line of defense against the Guardian and its Vasteel Technology weapons. They would later go on and serve alongside the Galaxy Federation's Fire LEO starfighters in the battle to save the Earth from the invasion by the ORN Empire.
