'''''Ambassador''-class | The '''''Ambassador''-class emissary''' has served Starfleet as a venerable workhorse since the first quarter of the 24th century. Over their decades of service, they have served in many roles. Originally designated as the first class of explorer-type vessels in Starfleet, they were gradually pulled back from most frontline operations and served capably as diplomatic, scientific, and tactical platforms for duties within Federation space as exploratory cruisers following the introduction of the ''Galaxy'' class of explorers in the early 2360s. By the 2380s, they were considered heavy cruisers, and in 2400 Starfleet moved to transfer them to [[Starfleet Auxiliary]] in disarmed roles. This decision was reversed in 2401, because of a desperate need to shore up the fleet following Frontier Day. The disarmament process was halted and the remaining ''Ambassador''-class starships have reentered service now designated as emissaries, focusing primarily on diplomatic and humanitarian missions to allow more modern vessels to take scientific and tactical duties. | ||

Twenty-eight large dedicated laboratory facilities are included in the ship, along with facilities to convert three of the cargo bays to hold extra scientific equipment if necessary.

As of 2401, the remaining ''Ambassador''-class starships in mainline service have been retrofitted with modern scientific equipment.

She was one of the first classes to include extensive support for variable atmosphere and gravity accommodations to assist in diplomatic dealings with lifeforms who are not from M-class environments. A full 50% of her high-quality guest quarters and all of her elaborate conference facilities were originally able of being quickly configured for K, L, O, or P-class environments, and this capability was extended in the 2370s to include high-temperature environments. Most vessels of this type have also been retrofitted with holographic projectors either in the whole ship or in diplomatic areas to allow for quick reconfiguration of facilities for different negotiations. An ''Ambassador''-class ship is capable of hosting multi-party talks in great comfort, while also being a suitably-powerful ship to not need an escort when going into hostile areas. | ||
When they reentered service in 2401, ''Ambassador''-class ships were designated formally as emissaries, the diplomatic and humanitarian equivalent to explorer-type starships. Working alongside their much newer ''Obena''-class counterparts, these revamped ''Ambassadors'' work to shore up internal and external relations for the Federation, so that newer and more advanced cruisers can be sent on defensive and exploratory missions instead. Where possible, they have been given a literal and metaphorical fresh coat of paint—new finishes, new furniture, and new communications equipment—while retaining their original grand and sophisticated design features, such as dedicated ballrooms, concert halls, and the like. | |||

''Ambassador''-class ships were among the fastest vessels of their time, retaining speed records that weren’t broken until the ''Galaxy''-class was launched in the late 2350s.

Compared to newer starships, more of an ''Ambassador''<nowiki/>'s maintenance needs are manual, even with increased automation. Her overall sprint capabilities are also lower. Given the age of the systems on this class, individual vessels may have quirks and issues not expected in modern ships. These vessels often have several different generations of technology working together, such as isolinear main computers interfacing with first-gen bioneural systems in some computer labs, which then connect to bioneural-isolinear control arrays in the new communications systems.

Initially envisioned as early as 2300, the ''Ambassador''-class was designed as not only the next greatest exploratory ship for Starfleet but also as the first of an entirely new classification of starship: explorer, as opposed to a mere heavy cruiser. Development was done at a relatively slow pace, given that the Federation was in a sustained period of peace and the ''Excelsior''-class was performing above expectations. Starfleet wanted a design that would introduce as many revolutionary systems as her predecessor had, which led to a long prototyping period with other less-capable ships, such as the ''Renaissance''-class light cruiser and the ''Freedom-''class frigate. These technologies included the next generation in warp coils, phasers, shields, and scientific systems, as well as diplomatic facilities that would make the ''Ambassador'' a powerful symbol of the Federation’s values. | Initially envisioned as early as 2300, the ''Ambassador''-class was designed as not only the next greatest exploratory ship for Starfleet but also as the first of an entirely new classification of starship: explorer, as opposed to a mere heavy cruiser.

The Ambassador-class emissary has served Starfleet as a venerable workhorse since the first quarter of the 24th century. Over their decades of service, they have served in many roles. Originally designated as the first class of explorer-type vessels in Starfleet, they were gradually pulled back from most frontline operations and served capably as diplomatic, scientific, and tactical platforms for duties within Federation space as exploratory cruisers following the introduction of the Galaxy class of explorers in the early 2360s.

The disarmament process was halted and the remaining Ambassador-class starships have reentered service now designated as emissaries, focusing primarily on diplomatic and humanitarian missions to allow more modern vessels to take scientific and tactical duties.
Science and Exploration
The Ambassador-class starship was intended to be as revolutionary to the exploration of space as the Constitution was in her time; an order of magnitude more capable than the Excelsior-class ships serving as Starfleet’s premiere exploratory vessels in the 2330s. Indeed, this class was the first to be designated as an explorer rather than as a cruiser, given that she was designed to undertake true five-year unsupported missions outside of Federation space.
By the early 2370s, she had been reclassified as an exploratory cruiser but retained impressive scientific and exploratory capabilities that have continued to make her a desirable command. The class contained the most powerful spaceborne sensor arrays of their time, and her eighteen modular sensor pallets continue to be able to use the latest scientific scanner equipment. Twenty-eight large dedicated laboratory facilities are included in the ship, along with facilities to convert three of the cargo bays to hold extra scientific equipment if necessary. This gave the Ambassador an estimated 325% increase in research capabilities over an Excelsior, and she remains significantly more capable than light cruisers and smaller, more modern-exploratory vessels.
As of 2401, the remaining Ambassador-class starships in mainline service have been retrofitted with modern scientific equipment. As their role is primarily diplomatic and humanitarian, Ambassador-class ships' science departments are often working on data analysis and other independent projects secondary to the ship's primary mission.
Diplomacy
As her name would suggest, an Ambassador-class starship are of the most capable diplomatic platforms in Starfleet and remain an excellence choice for most diplomatic missions in and near Federation space when an Obena or Odyssey-class ship is not available. She was one of the first classes to include extensive support for variable atmosphere and gravity accommodations to assist in diplomatic dealings with lifeforms who are not from M-class environments. A full 50% of her high-quality guest quarters and all of her elaborate conference facilities were originally able of being quickly configured for K, L, O, or P-class environments, and this capability was extended in the 2370s to include high-temperature environments.

Where possible, they have been given a literal and metaphorical fresh coat of paint—new finishes, new furniture, and new communications equipment—while retaining their original grand and sophisticated design features, such as dedicated ballrooms, concert halls, and the like.
Engineering
Ambassador-class ships were among the fastest vessels of their time, retaining speed records that weren’t broken until the Galaxy-class was launched in the late 2350s. These vessels were the first to use the second generation of the semi-toroid warp coils that became standard after the launch of the Excelsior-class three decades earlier.

Now, Starfleet's decades of experience with this ship have allowed them to reduce the engineering crew complements substantially, leaving more room for scientific, diplomatic, and humanitarian personnel.
An Ambassador-class ship also maintains relatively large cargo bays and auxiliary craft facilities, alongside industrial replicators and other systems that made her a very effective vessel for humanitarian missions or construction projects.

Managing these cross-generational systems can be very challenging.

The Type-IX phaser array was developed for use aboard the Ambassador. This measure greatly increased the ability of the Ambassador Class to fire sustained bursts and greatly reduced the recharge and cool down times. The use of an independent power system for every group of ten emitter segments in the array triples the survivability of the array compared to a ball turret, while there are also benefits to the reaction time, greater control of thermal effects, field halos, and target impact.

Shipboard Life
As with many designs that were once launched as flagships, the Ambassador-class is now a reliable workhorse for the Federation. Crews aboard these ships tend to enjoy their assignment, as the class has been retrofitted with most of the amenities you would find aboard newer explorers, such as holodecks, arboretums, and lounges, as well as comfortable crew quarters.

These technologies included the next generation in warp coils, phasers, shields, and scientific systems, as well as diplomatic facilities that would make the Ambassador a powerful symbol of the Federation’s values.
Construction on Ambassador, Surak (renamed Enterprise before launch, while the name Surak was transferred to a second-run vessel of the same class), and Zheng He began in 2323 at Utopia Planitia Fleet Yards. Ambassador was launched in 2329, followed by her sister ships in 2332 and 2333, respectively. Despite retaining a crew size of 750, they required nearly twice the time and twice the resources of an Excelsior-class starship, while only giving approximately a 50% improvement in overall capabilities. Though they were markedly better at scientific and diplomatic missions, they were too expensive to replace the Excelsior in her role as a capable multi-mission platform, and both classes continued to be produced alongside one another until Excelsior and Ambassador were replaced by the Nebula-class in 2355 and the Galaxy-class in 2358, respectively.
During her production run, the Ambassador-class was generally built at a rate of two units per year, with 75 of the class built in total. This made them rare compared to the Excelsior-class which was built in the hundreds and they were generally reserved for high-status assignments. They proved popular in service to both their crews and to the admiralty, though they were eclipsed by the Galaxy-class which was substantially more powerful and useful in every respect.

In Play
- Ambassador-class ships were capable heavy cruisers built in smaller numbers than the older Excelsior, but still relatively common. Functionally, they had a lot in common with the Galaxy-class, but the newer ship eclipsed it in every measure. Because of this, the Ambassador was a solid, relatively-generic heavy cruiser that could go on nearly any mission and expect to perform adequately. They wouldn't often be sent on long-range missions alone anymore.
- An emissary is like a courier, but much larger. Ambassador-class starships do as their name suggests: they perform important diplomatic functions in and around Federation space, negotiating with the Federation's allies and trying to make the galaxy a safer place through diplomacy. They also perform humanitarian functions.
- These ships are old, but they're not second rate. Pound-for-pound, they're just as capable ships from the 2360s and 2370s, though they do lag behind the most modern ships. They have good bones, large, powerful warp cores, and 70+ years of experience in the technical manuals on how to get them to their full potential.
