STSTCSOLD&A | Ambassador Class ● Heavy Cruiser ● United Federation of Planets

NOT TO BE CONFUSED with FASA's own Ambassador cruiser, the actual Ambassador Class of Trek canon did not appear until the ST:TNG episode "Yesterday's Enterprise". Constructed under the assumption that the Ambassador had to bridge the design gap between the Excelsior cruiser and the Galaxy Class exploration series, the model does incorporate many elements from both of the previous ships. However, I've often thought that the Ambassador also borrows from the Constitution Refit in that its engineering hull is remarkably tubular in design, with a large, circular deflector dish. The secondary hull of the Galaxy is too flattened and elliptical, while the Excelsior hull isn't a circle nor is it an ellipse, so the Ambassador's engineering hull seems very 'retro' in comparison.
When it comes to combat, I was unsure how to rate this vessel. There is much evidence to suggest that the Ambassador is an explorer, like the Galaxy which would follow it. There is also much evidence to suggest that the Ambassador is a fighting man's ship, equipped with a potent array of phasers and torpedoes. Therefore I have taken the middle road, assuming that the Ambassador's pedigree is the same as its ancestors, the Excelsior and the Consitution: a heavy cruiser loaded down with science and exploration equipment, but also armed for bear in the event that the Ambassador has to deal with hostile situations while exploring the Federation frontier.
I also made the assumption that the Ambassador is designed to have a lengthy lifespan, like the Excelsior before it, so that any late-model ships ought to be as well armed and well equipped as possible, bringing them roughly up to par with their younger, more potent siblings, like the Sovereign Class. Naturally the Ambassador shouldn't be an exact match for the mighty Sovereign, but a late-model Ambassador ought to at least be close to an early-model Galaxy.
