1.0 AMBASSADOR-CLASS INTRODUCTION
1.1 MISSION OBJECTIVES
Pursuant to Starfleet Exploration Directives 902.3 & 914.5, Starfleet Defense Directives 138.6 & 141.1, and Federation Security Council General Policy, the following objectives have been established for an Ambassador Class Starship:
Provide a multi-mission mobile platform for a wide range of scientific and explorative research projects.
Augment Excelsior Class Starships as the primary instrument of Federation deep-space defense and exploration.
Provide autonomous capability for full execution of Federation defensive, cultural, scientific, and explorative policy in deep space or border territory.
Serve as a frontline support vehicle during times of war and emergencies.

1.4 GENERAL OVERVIEW
History written by: Steve Mallory - based on information found in Star Trek: First Contact, Star Trek: Voyager, Star Trek Technical Manual, Star Trek: The Next Generation Technical Manual, Star Trek: Deep Space 9 Technical Manual, and Star Trek: The Magazine. The style of the history is based on histories presented in the Startrek Spaceflight Chronology by Stan Goldstein, Fred Goldstein, and Rick Sternbach. Please keep in mind that this is a history developed based on canon information presented in various sources and filled in with logical conjecture.
Now an important footnote in the lineage of many a starship, the Ambassador Class is no longer the backbone of Starfleet's exploration nor defensive arms. Once the pride of the fleet and considered, at the time, to be the pinnacle of starship development, technology developed for the Ambassador class has exploded into common usage among other classes of starships, while the grand spaceframe has slipped from active production and is slowly being replaced by newer designs, it still remains a notable class of vessel that continues to serve with distinction.
The Ambassador Class starship was a large departure from current trends in ship design when it was conceived. Nearly twice as large as the current mainstay, the Excelsior Class starship, the Ambassador class would change the face of Starfleet and influence ship design for decades to come. Initial design concepts were developed and toyed with at the newly formed Advanced Starship Design Bureau, Mars in 2249; some of the first concept models and drawings are still on display at the ASDB Museum. However, given the scale of the craft, the concept would remain just that until 2292, when a dramatic shift in Galactic Politics occurred. A shift that would effect the Federation, the Romulan Star Empire and the Klingon Empire well into the next century.
