(Translation: The D-7 Class battlecruiser served as the backbone of the Klingon Imperial Fleet during Earth’s 23rd century. It was used during the 2256 Klingon-Federation War and the Romulan Star Empire began using the class around 2268. The D-7 class was eventually replaced by the upgraded K’Tinga class, beginning in the 2270s.)

The D-7 battlecruiser used in the original Star Trek series was designed by Matt Jeffries and made its first appearance in Season 3’s The Enterprise Incident (because someone stepped on and broke the Romulan warbird model). AMT was contracted to make two filming models. The first model, painted overall gray, was delivered to Paramount and AMT kept the second one to pantograph down to ½ the filming model’s size in order to produce a 1/650 model kit. Because of this, AMT’s large D-7 kit is probably the most accurate of all the Star Trek models they produced. Upon receiving the first model, Jeffries painted much of the hull a light gray-green color. Once AMT had finished with the second model, it was delivered to Paramount to act as a standby, in case the first was damaged, or in case a second ship was needed for a scene. Jeffries painted this model to match the first one. The second model was never used and sat in Gene Roddenberry’s office until the series ended. The first D-7 model was donated to the Smithsonian and the “Roddenberry Model” later changed hands several times before being sold at auction in 2006. In the late 1970s, the first filming model was taken back from the Smithsonian, to be used in the Star Trek: Phase Two television series, and a third, darker green was added to the model at this time. The series was eventually cancelled in favor of a movie, Star Trek: The Motion Picture. The model was too small to be used for the large screen, so a mold was made of it for the studio to use to make a new battlecruiser that was twice as large. The model was then repainted overall gray and returned to the Smithsonian. The Roddenberry Model has remained in its original green and gray pant scheme.



The Alliance Models D-7 is about 7 inches long, so it is a good option if you are like me and don’t have room to display the Polar Lights 1/1000 kit or the AMT 1/650 kit. It is 1/1400 scale, which is a common scale for Star Trek resin kits. It is beautifully designed and cast. I only found one tiny bubble to be filled in any of the seven parts. The kit also includes a section of brass rod and strangely, a Starfleet insignia for a stand. A small decal sheet is provided, but no decal placement guide is included for the many small decals included on the sheet. The kit is missing the two tractor beam emitters on the underside of the bridge section and two plates on the grills on the main hulls. It also includes K’Tinga-style impulse engine exhausts on the stern that are not present on the filming models. We’ll just call this is a post-Original Series upgraded version of the D-7. 


I have to admit that I am sort of a scale snob; I like to have my models in a uniform scale. I tend to stick to 1/48, and anything larger than an F-4 Phantom gets built in 1/144. My first small Trek kit was Starcraft’s beautiful 1/1400 Klingon D-5 battlecruiser, from the Star Trek: Enterprise series, so now all of my Trek models will be in that scale. Fortunately, there are lots of resin kits available in this scale, and most don’t take up a lot of space in the display case, although something like USS Enterprise 1701-E turns out to be almost 20 inches long. The D-7 and K’Tinga are two of my favorite sci-fi ships, so I couldn’t resist this D-7 kit when I found it in Federation Models’ catalog.

Assembly went pretty fast. The parts required only a little cleanup in some of the indented areas and a couple of passes with a sanding stick to take care of the mold parting lines. I had to heat the neck of the forward hull to straighten it out, since it was drooping a little. I also found after I attached the engines that the main hull was slightly warped, so I have to go back and carefully straighten that as well. Such warping occasionally happens in resin kits and it is usually easily fixed.

The fit of the parts was excellent. I only had to use a little filler where the neck attached to the main hull and the seams where the engines attached. I had the model ready to prime within a couple of hours.



After wiping the model down with denatured alcohol, I primed it with Tamiya gray primer. The source for the history of the D-7 filming models recommended Tamiya XF-66 Light Gray for the gray and Tamiya 33% XF-21 Sky + 66% XF23 Light Blue for the gray-green. The metallic grills on the hull and upper superstructure on the filming models were covered in mylar. I used Alclad Dark Aluminum, because I didn’t want any bright metal on my model.

Once the paint was dry, I sprayed a coat of Future on the model to prepare the model for decals. Alliance provides the Klingon lettering in gray, so I used some white letters from an old JBot sheet I had picked up somewhere. The Klingon insignia look great on the decal sheet, but they’re not backed by a white undercoat, so the underlying gray paint can be seen through them. I used the insignia from the JBot sheet, but had to paint over the red areas, because the red ink dots were plainly visible. I think better results can be obtained by using a photocopy of the decal sheet to cut masks and just painting the insignia and lettering. I replaced the brass rod with a clear acrylic rod, and that was it for final assembly. One of these days I’ll order a proper Klingon insignia base from Shapeways.


 I really enjoyed this model. It was simple to build and paint, and certainly looks the part of the D-7. The decals were a letdown, due to the lack of a white background. I’ve been told a K’Tinga is also in the works, which should be lots of fun to paint, with its raised hull plating.
