...but the Ark was abandoned when they built Autobot City. Teletran-1 would've been moved or, more likely, decommissioned. They probably scuttled the Ark. *shrug* The G1 cartoon does mention that the Autobots relocated their Earth base from the volcano to Autobot City but doesn't mention the fate of their old spacecraft (the Ark). In the G1 comics the Ark was actually restored and made flightworthy again... until Grimlock trashed it during the battle of Unicron, but then Shockwave and Starscream repaired it... until Ratchet blew up the engine room and crashed it into Canada... but then it got rebuilt in G2... until Fortress Maximus & Spike did a kamikaze. Poor Ark.
