Going by the numbers, there would have to be 30 Megaroads, and at least 12 New macross Class out by the time of VFX-2. Since the Macross 13 hadn't launched on a colony mission, & was still in Earth orbit, it should be safe to assume that it hadn't been completed/left Earth yet. Others have questioned whether New Macross & Megaroads were re-used for new fleets, but that doesn't even remotely make sense, since the City portions of the ships were the main basis for the initial colonization, and the Battle portions would almost definately need to stay for planetary defense. The more likely answer, is that the 11th Super Long Distance thing is either a translation error, the Frontier fleet is based around the 11th of the New Macross class, or it's based around the 11th of a newer colony ship design.
