Star Trek Cheyenne Class
- This highly detailed resin model kit is of the Cheyenne Class starship which first featured in Star Trek: The Next Generation. The kit has been produced at 1:1400 scale so as to be in line with the larger AMT/ERTL Enterprise C, D & E kits. Once assembled the kit is 10.5” long and includes assembly & painting instructions, decals and a base.
- The Cheyenne-class was a type of Federation starship in use by Starfleet in the 24th and 25th centuries. (ST reference: Star Trek Encyclopedia) History Edit. The Cheyenne-class was a 24th century design of light cruiser, consisting of a saucer section derived from the Galaxy-class project with four warp nacelles attached by branching pylons to the aft saucer.
The Cheyenne class was a Federation starship class that saw service during the 24th century. The class was one of the few classes to have more than two warp nacelles; like the Sadat, Constellation and Cheetah classes of the previous century, it had four nacelles. At least one Cheyenne-class.

Notes
The Cheyenne project was approved in 2338 as a scoutship to counterpart the New Orleans class Frigate and the upcoming Galaxy and Nebula class Explorers. As with most scouts the Cheyenne was intended to be somewhat faster than its contemporaries in order to allow it to travel out ahead of the main body of a fleet. In order to accomplish this, the Cheyenne was fitted with four nacelles in the pattern established by the much earlier Constellation class.Initially, all did not go well with the Cheyenne. Starfleet has relatively limited experience with four nacelle designs, and a good deal of difficulty was experienced with the warp field geometry. Eventually these problems where overcome and the USS Cheyenne, launched in 2344, achieved a maximum speed of Warp 9.4 in trials. However, in December of 2344 the Galaxy project received new specifications calling for a top speed of Warp 9.63. With the prototype about to enter service and five more ships under construction, it was already too late to make any serious attempt to improve the top speed of the Cheyenne, so Starfleet was forced to bring a scout into service which was some 10% slower than the vessels it was supposed to work with.
Over the succeeding years several attempts where made to bring the speed of the Cheyenne up to Warp 9.7, but problems with the field geometry began to re-surface with alarming regularity. This culminated with a test on board the USS Ahwahnee; when a new computer control system was tried out the ship created a wormhole effect on its first test flight. Although the Ahwahnee survived and there where no casualties, the subspace stress caused severe cracking in the hull structure of all four nacelle struts. The ship was in spacedock for over a year while the struts where replaced. Starfleet suspended production of the class in 2352 after twenty five had been commissioned, mothballing the six ships under construction.
The Cheyenne has proved less than successful in service. Her relatively low speed has restricted her performance in her designed role, and she has been forced to operate in the role of a Frigate. She is not especially suited to this task - certainly not when compared to the New Orleans class which was purpose designed for the role. As a result the Cheyenne's have been given a very low priority for refits and upgrades, and have fallen considerably behind the rest of Starfleet in this respect.
With the advent of more modern scout ships such as the Intrepid, the Cheyenne was to be gradually retired from service. The increase in hostility in the alpha quadrant over the last ten years has led to this decision being reversed, and the Cheyenne's have played a small part in recent conflicts. The most notable contribution was Wolf 359, in which the USS Ahwahnee was destroyed by the Borg4.

Comments
The only appearence of the Cheyenne class to date is the USS Ahwahnee, which appeared in the Wolf 359 graveyard scene. The picture on the images page isn't great, but it's the only one I've ever been able to find. I've judged the ships dimensions length from this image, and assigned it as a scout because of the relatively small size.The back story about problems with the four nacelle layout is a copy of the Constellation problems - since these are the only two Starfleet ships with four nacelles it seemed reasonable that they would both suffer from the same glitches. The stuff about the Galaxy class getting new speed requirements is from the TM, page 56/57, and it seemed reasonable that the Cheyenne would suffer accordingly if it was a slightly earlier ship.
Other than that it's mostly speculation. Since we haven't seen one single Cheyenne in service over the years, I guess they must be small in numbers and on their way out. If anybody has a better picture of this ship, I'd appreciate it if you'd post me a copy.

Introduction
The Battle at Wolf 359- New Orleans
The New Orleans class includes the USS Kyushu NCC-65491, USS Renegade NCC-63102, USS Rutledge NCC-57295 and USS Thomas Paine NCC-65530. Only the Kyushu could be seen on screen, as part of the wreckage at Wolf 359 (image). It is the heavily damaged ship next to the OPS console and is also mentioned in the dialogue. The ship was built by Ed Miarecki.
Since all the Wolf 359 ships are presumed to be composed of Galaxy parts, it was not completely clear if the ship on the left edge in the second scene is actually the New Orleans, or maybe rather the Cheyenne or the Springfield. However, Chris found out that the damage pattern is identical to the one on the New Orleans model.
References
The first printed depiction of the New Orleans could be found in the Star Trek Encyclopedia I, but the small black & white photo only reveals that the ship looks similar to a Galaxy class, with different warp pylons and two additional pods on the top of the saucer. The Star Trek Encyclopedia II features two color images of the Kyushu, one top and one bottom view. I previously thought it could be CGI reconstructions of the undamaged model of which there might be no photo at all. Considering the lighted windows, glowing nacelles and the artificial background, the image has obviously been manipulated. Still, some of the typical features of a real model become obvious already here. These are actually photos taken of the miniature just before Mike Okuda added the battle damage. It becomes evident that almost exclusively Galaxy-class parts have been used for the model, yet with extensive modifications.
Another New Orleans-class image was presumably first shown by Mike Okuda on a convention and has been retouched in the course of its dissemination, now sporting a black and blue star background. The best image of a New Orleans-class ship so far was featured in the Japanese book Star Trek Mechanics.
Analysis
All reference images doubtlessly prove that a Galaxy-class saucer, engineering hull and nacelles form the basis for the New Orleans-class model. It would have been easier to modify the 1/2500 scale model whose surface is mostly flat, as it has been done for the Cheyenne class too. The relatively good detailing, however, of the phaser strips, windows and escape pods (image) insinuates that the model uses parts of the 1/1400 AMT/Ertl Enterprise-D. This has recently been confirmed by Ed Miarecki. A lot of differences to the Galaxy become obvious when we further study the reference images. First of all it is obvious that the windows and lifeboats have been modified so as to suggest the New Orleans class is a significantly smaller ship than the Galaxy class. Generally, two decks were combined to one. This allows a first estimation of the ship's length which would be around 320m, half as long as a Galaxy class.
The New Orleans class sports two additional pods on the top of the saucer and one pod underneath the engineering hull. It is in dispute among fans whether these pods are supposed to hold auxiliary warp engines, photon torpedo tubes, sensor arrays or even shuttlebays, but this has to be clarified by the starship designer, provided they are intentional design elements at all. Considering the text marker nacelles of the Cheyenne class, the pods are apparently made of text markers (most probably from Schwan Stabilo) likewise, which would work perfectly with the 1/1400 Galaxy model kit.
Since the model is based on the 1/1400 scale Enterprise-D, the comparably larger bridge is probably a custom-made part. Note that deck 1 is just an ellipsoid (image), much less detailed than that of a Galaxy class at the correct scale. Nevertheless, the shape of the bridge module, including deck 2, clearly indicates that it is supposed to be the Galaxy-type module. This will be the basis of my final size estimation.
The top views of the New Orleans class do not look much different from those of the Galaxy class, except for the mentioned detail changes. In contrast, the two bottom views in (image 1, image 2) show that, compared to the Galaxy class, the engineering hull is much closer to the saucer. This can only have been accomplished with a shortened neck. I assume that the lower end of the Galaxy neck has been cut off, and the center impulse engine attached again. The engineering hull has been significantly extended, either with a custom-made piece or a combination of two hull parts and lots of putty. This is confirmed by the existence of two phaser strips (image), one originally belonging to the forward and one to the backward hull piece. It also becomes obvious in a comparison of the top and the bottom views. The engineering hull front end is right beneath the saucer center, while its rear end is in the same place as it is on the Galaxy-class model. Moreover, the rear end has been modified and the undercut covered.
The wing-like Galaxy-class warp pylon structures are missing and the nacelles are attached to custom-made pylons instead. The bottom view shows that the pylons are simple parts without detailing, possibly made of plain polystyrene sheets. The nacelles are the same as of the Galaxy class at the first glance. Nevertheless, I am sure that the original Galaxy class nacelles have been extended at the aft end (image). There is strong evidence for this assumption:
1. The two top views show apparently thinner nacelles than a view of a Galaxy-class ship from the same angle. It could be objected that this might be an illusion because a part of each nacelle could be shaded, but I doubt this would apply to both nacelles on both images.
2. The nacelles of the damaged Kyushu model are apparently not as long as those of the intact models. Nevertheless, these images can prove my assumption as well. The complete Bussard collector section (front tip) of the starboard nacelle is missing (image), and the rest of the nacelle alone is as long as a complete Galaxy-class nacelle, unless the image was falsified when it was first retouched. The port nacelle, on the other hand, is lacking the rear end, and the rest has about the same proportions as a Galaxy-class saucer viewed from the same angle.
3. If the nacelles were nevertheless unchanged Galaxy class nacelles, they would not be of the same scale as the saucer, but somewhat larger. This is possible, but improbable, no matter if a 1/2500 or a 1/1400 model kit was used.
4. The top views in show two pairs of deepenings (plasma vents) in the nacelles, one close to the rear end and one about in the middle. The Galaxy-class nacelles, however, have only one pair. It is obvious that the far smaller New Orleans class nacelles are supposed to look different from the type used with the Galaxy class. This can be accomplished attaching another rear end to each nacelle, rather than scratching out two additional holes which would not be worth the effort.
5. My reconstructed top view, based on the assumption that a second nacelle aft end has been attached, results in exactly the appearance of the nacelles as best seen here. This cannot be a coincidence.
6. Both top views show an area of different color between the two pairs of plasma vents, as if the putty is visible despite the overall paint coating of the model.
Based on my side-view schematic, Masaki made a sketch of what was used to build the ship. The Kyushu was built by Ed Miarecki using the AMT/Ertl 1/1400 Enterprise-D kit. He stretched the secondary hullby putting together two thirds of the front and two thirds of the rear end. He did something similar when he added another rear end to the warp nacelles. Thebigger bridge module is scratch-built, considering that there is no larger kit of the Enterprise-D. The three large 'pods' were later added by Mike Okuda using marker-pens.
Supplement
More than three years after I wrote this article, we finally have a bunch of pictures available that show details of the Kyushu studio miniature. The following are screen caps from the TNG season 3 DVD. Enjoy!
One observation is that, unlike we assumed so far, the single lower pod is not directly affixed to the engineering hull, but with a distance of about the pod height itself. It also becomes obvious that, as seen from the side, the nacelle pylons are sloped backward and not exactly vertical. This is already corrected in my above side view schematic.
In 2015 and 2016, Rick Sternbach managed to dig up several more photos of the various ships built by Ed Miarecki and used for the Wolf 359 shoots, all taken before the models were damaged. They include the first good pictures of the undamaged New Orleans class.
Conclusion
Given the known size of the Galaxy-class bridge module, the New Orleans class is 340m long and 246m wide according to my above diagrams. It is interesting that the saucer seems to be smaller than that of the Cheyenne (262m wide). The limited accuracy of my reconstructions would allow the interpretation that they are actually supposed to be the same at 1/1 scale. Yet, the Cheyenne miniature uses a 1/1400 bridge module on a 1/2500 Galaxy hull, whereas the New Orleans is a 1/1400 model with a custom-made bridge. It is rather unlikely that these size relations are exactly the same. So the saucer of the 1/1 Cheyenne, which is turned upside down anyway, can be supposed to be a different design with a different, slightly larger size.
Although the New Orleans is probably smaller than it would be if the saucer were the same as of the Cheyenne, several decks seem to have a height of more than 4m each, provided the bridge module has two decks with the usual 3.5m height. The New Orleans-class escape pods being simple rectangles, they are not necessarily the same size as those of the Galaxy, so they are not a useful reference.
