Ark-17

The Ark-17 is an Autobot starship in the IDW comics Generation 1 continuity family.

Springer used the Ark-17 as a platform from which he launched his operation to rescue Kup. The ship housed seemingly endless hordes of Autobots that Springer threw at the crazy and powerful Kup. But eventually, Trailbreaker rendezvoused with the Ark-17, and he easily rescued the old coot.

(In the IDW comic universe there are many Autobot ships designated Ark. They are all presumably named after the first legendary lost Ark. They are differentiated by a number following the name. Hence: Ark-19)
