Lo'gaN's thread is mired with discussion, so I thought I'd show some initiative and set up a separate submissions thread.
Absolutely no interplay about the merits of a what a flagship should be or whether a particular submission should even be considered. This thread is just a collection of the ideas in one place. So please add yours.
Tell me that wouldn't make an awesome Klingon Flagship, with the proper design adaptions of course. Greener, meaner, and bulkier. Possibly keep the superweapon as a counterpart to the Gal-X Dreadnought's.
