Ok here goes, I have included some links with some pretty good descriptions and specifications. I will have to say that the Wunderwaffe link is an overall great link catorgorizing and listing a variety of units from ships, missiles, interceptors, bombers, and land units. The luft46.com has more aircraft than I could list in one sitting, but a great site for just about every German prototype aircraft.
