Quintesson spacecraft

The Quintessons have a great many varieties of ship in their armada.

Quintesson "jetski"
The Quintesson ship carries several of these airsleds for moving troops rapidly across the battlefield. They can be manned by one or two beings, and are armed with a central cannon. Though airsleds are used by shock troops today, Quintesson judges have occasionally been known to make use of them.

"Science ship"
The Quinesson science ship features a unique forward-mounted engine design and can be equipped with a mirage sequence for disguise. The research ship is equipped to crew nine (with nine escape pods) though it can be manned with a crew of 1, providing he has an assistant familiar with its functions.

This "Research ship" seems to be the same size as the Quintesson Warship. While it's possible that it may serve a similar function as an auxiliary craft docking within the Quintesson Cruiser, this has never been shown.

"Meeting ship"
The 'Meeting ship' appears to serve no military or scientific purpose. Only about twice the size of The Dweller, most of the ship's internal volume is given over to a large meeting space.

Passive-aggressive comments about 'other bands of Quintessons' could indicate that the conclave on this ship represents the legitimate central authority of Quintesson government after Quintessa's destruction... but it's difficult to say.

"Ancient" ships
11 million years ago, when the Autobot rebellion forced the Quintessons off of Cybertron, they evacuated in many ships of a similar (but not identical) design. These designs all had a long slender 'cigar' type body and small horizontal wings off the back.

These ships are able to land and take off like plane. The design no longer appears to be in common use.
