With the announcement of Star Trek online and all the implications thereof I started thinking on what dedicated repair, medical and science vessels might look like in a "historical" (as in "not-made-up-for-this-game") sense. Below is are the first fruits of my pondering:
I'm going to try and eke out some time to color her. What do you guys think?
Designed in the 2340s, the Eiffel class ships are large workbee and cargo carriers that are tasked with building subspace relays, small starbases, and serving as a mobile repair control center for large fleets away from central starbases.
Eiffel class ships can work alone, carrying the materials they need in their massive dorsal cargo bay, or in tandem with starfleet tenders and cargo haulers for larger construction projects.
The dorsal saucer contains 7 auxillary craft bays which are all connected by a central maintenance space. These bays store the Eiffel's workbee squadron. A bay on the ventral section of the saucer houses conventional shuttlecraft and a pair of runabouts.
Living spaces are contained in the dorsal "spine" between the saucer and the cargo bay, with the engineering hull housing a twin M/AM reaction core drive system used to power the Eiffel's over-sized nacelles. This extra power is used to generate larger than usual subspace fields, allowing Eiffels to tow disabled ships or large construction components with them through warp.
