A Nebula hot-rod! I've always loved the Nebula class and wish more configurations beyond a sensor dome or weapons pod had been presented. I've always thought that many other options might be interesting, such as a landing platform for craft just a bit too large for a standard shuttle bay, to provide support for recon/fighter/whatever squadrons, etc. And a place for those poor DS9 runabouts to park beyond large stations! Or in my own little universe, these stealthy AWACS peregrine falcon thingies. (While I've done some of the modeling here, some elements are the work of others, especially flateric's nebula model, rduda's chairs/desks/etc, main shuttlebay island structure from Aryh-Peixoto-Filho). The back half of the main shuttle bay has been widened beyond other fan designs to allow berthing for peregrine-sized craft. (Also, as a side-note, notice how much of the Galaxy-class saucer should have been visible outside the ready room and observation lounge windows!)
This is my first posting here, so If this is the wrong place to post this kind of thing, admins feel free to remove this of course!
