Robotech S01E05 - Transformation

Having been rescued from the fallout shelters of whatever is left of Macross Island, the citizens attempt to normalize their life aboard the giant battle fortress. Roy Fokker encourages Rick to join the Robotech Defense Force. The SDF-1 crew discover that the spacefold drive they used to make the jump has disappeared, but stumble upon an idea to transform the ship. The idea is soon tested in a battle with the Zentraedi, but renders much damage to Macross City.
