The '''Niagara-class | }}The '''Niagara-class fast cruiser''' is an exceptionally fast but also exceptionally odd starship, dating to the 2340s. Developed as a larger and more capable successor to the [[Constellation Class|''Constellation''-class fast cruiser]], its current configuration shows commonality with both the [[Ambassador Class|Ambassador-class heavy cruiser]] and the [[Galaxy Class|''Galaxy''-class explorer]], thanks to a refit in the early 2360s. While the initial design specifications called for simply a smaller, more efficient version of the ''Ambassador'', in practice, these ships' unique engine configuration has made them difficult to operate and they didn't receive a large production run. While Starfleet began to convert them for Auxiliary service in 2400, this decision was reversed following the disastrous impacts of Frontier Day 2401, and this class is re-entering mainline service with the upgrades necessary to serve in the 25th-century Starfleet. | ||

It also has a comprehensive sensor suite installed in the lateral band of the saucer section, which makes it quite capable of performing scientific studies. These vessels are generally reserved for fast response operations to carry humanitarian supplies or respond to distress calls, but they still often carry secondary mission equipment for various Starfleet and Federation science agencies and continue to passively collect data about the universe that they relay back to Starfleet. Because of their high speed, they are also sometimes used to deploy or retrieve long-range probes, which is an important but banal task that newer vessels are usually not assigned to do. On occasion, these ships are still used as first-line exploratory scouts, where they provide initial scans of a region before explorers perform more detailed surveys. | ||

[[File:Niagara3.jpg|thumb|A front quarter view of the ''Niagara'' class.]]The vast majority of Starfleet vessels use even pairs of warp nacelles, as this configuration has been proven the most efficient arrangement for Federation warp technology.

It's also the only one of the three not to be designed as a "dreadnought" in the way that the [[Federation Class|''Federation'']] or [[Galaxy Class Refit|''Galaxy'' Refit]] classes were. Rather than providing extra power to move more bulk, the third nacelle on the Niagara class is meant to provide a tri-lobed warp field which allows each individual nacelle to operate at a lower power level, thus reducing the stress on the warp coils and increasing the ship's effective endurance. Originally, these ships were built with nacelles identical to those found aboard the Ambassador, but the performance gains were considered marginal at best. While the ship was still considered a moderate success--they were substantially more capable than [Miranda Class|Miranda]] or [[Constellation Class|''Constellation''-class]] ships--they were complex to build and maintain and only ever saw a production order of about 40 units. | [[File:Niagara3.jpg|thumb|A front quarter view of the ''Niagara'' class.]]The vast majority of Starfleet vessels use even pairs of warp nacelles, as this configuration has been proven the most efficient arrangement for Federation warp technology.

The Niagara-class fast cruiser is an exceptionally fast but also exceptionally odd starship, dating to the 2340s. Developed as a larger and more capable successor to the Constellation-class fast cruiser, its current configuration shows commonality with both the Ambassador-class heavy cruiser and the Galaxy-class explorer, thanks to a refit in the early 2360s. While the initial design specifications called for simply a smaller, more efficient version of the Ambassador, in practice, these ships' unique engine configuration has made them difficult to operate and they didn't receive a large production run. While Starfleet began to convert them for Auxiliary service in 2400, this decision was reversed following the disastrous impacts of Frontier Day 2401, and this class is re-entering mainline service with the upgrades necessary to serve in the 25th-century Starfleet.

In the 2360s, the class was being evaluated for possible retirement in favor of the designs developed as part of the Fleet Modernization Program, but their basic spaceframes were considered too young to be discarded, even if their performance wasn't spectacular. Instead of retiring them, it was decided to replace their nacelles with the design used aboard the Galaxy and Nebula classes, as well as to upgrade their tactical systems. The resulting design is still quite awkward--the shape of the ship was optimized for a three-nacelle design, and so the refit needed to retain the third nacelle--but with these advanced engines, the ship is capable of comfortably cruising at Warp 8 (compared to the design cruise speed of the Galaxy being a mere Warp 6) and sprinting to Warp 9.9, which makes them one of the fastest cruiser designs in service even as of the start of the 25th century.
This speed comes at a cost, though, as the engine systems are difficult to maintain, especially considering that the number of engineers with experience operating tri-nacelle designs is extremely small. Structural integrity systems and the inertial dampeners aboard the ship are also complex and non-standard to handle the unusual stress loads created by the engines. Otherwise, the systems aboard this ship are pretty standard for the mid-24th century.
The Niagara's physical structure resembles the Ambassador but at a smaller scale, being roughly half the size of the larger ship. The design has a large shuttle bay on the stern, which can carry cargo shuttles or runabouts for use in humanitarian missions.
Tactical
Niagara-class starships are well-armed for their size, though they lack the armored hulls of later classes. This ship was designed with Type-IX phaser arrays, and in the 2360s, its weapons systems were upgraded to incorporate the new Type-X arrays, a total of 13 of them. These offered comprehensive phaser coverage with few blind spots. Torpedo coverage is fired by four class-six single-fire launchers, two forward above the deflector and two aft under the shuttle bay.
While primarily intended for humanitarian response duties, the Niagara is also capable of being a first response vessel to answer distress calls, which often involve combat situations. This is particularly true of members of this class stationed in frontier areas, where they are quite adept at striking against pirates.

This made them appealing targets to the Jem'Hadar, who targeted them to inflict morale damage on Starfleet.
As of the 2400s, a Niagara-class vessel would be a poor choice for a purely tactical mission, as her weapons and shields are at least two generations behind the current Starfleet standard. Her speed does allow her to perform well in reconnaissance roles, however.

In the 2350s, the last vessel of this class left the yards. The following decade, Starfleet considered scrapping them, but they were otherwise happy with the spaceframe, and since they no longer were going to build more anyway, it was decided to leave them in service. The Starfleet Corps of Engineers implemented a program to replace their nacelles with Galaxy-type nacelles, however, which raised their middling speeds to the very fast design they now have.
The increased top speed of this ship allowed it to go from a generalist light cruiser to a fast response and courier design. These ships were just settling into that role when the Princeton was destroyed at the Battle of Wolf 359.

Niagara class In-Play
- Three-nacelle designs are very rare, and this is both due to Gene Roddenberry declaring that Starfleet ships *had* to have even numbers of warp engines and because they just look weird. This seems to be an in-universe perception as well, with the phrase "third nacelle" being used on the show to refer to someone who's third-wheeling.
- This is a rare, aging design that still has its strengths (it's very fast) but which is so unusual that many officers might not even know it exists.
- A fast cruiser is a starship that's mainly intended to deliver very important supplies for engineering or humanitarian projects, but which may also find itself responding to distress calls.
- If you're an engineer, you might wish you had had the chance to serve on such a fascinating and unique starship.
