I decided to go with YF-23 instead of Su-47 Berkut, because this way I can keep things tied together slightly better.
There’s some points of interest with the YF-23. I’m not sure if it would be safe to say that the jagged shape at the tail end of the fighter is a recognizable shape in itself, but it does repeat itself at few points on the TSF where there really isn’t any reason to have a jagged shape outside generic appearance.
The thrusters have been turned into intakes in most cases, and even on the shoulder units the thrusters only have a superficial similarity to them. I counted it in because the overall appearance of the TSF YF-23 uses the juxtaposition of angles and smooth surfaces, albeit not really mixing them to any large degree.
As a rule of thumb when it comes to TSFs, the Jump units are miniature versions of the actual fighter. In Yf-23’s case you can see how well they managed to mangle the overall shape in order to fit the standard Jump unit design. Similar rule of thumb is the groin guard, which has surprising similarity with the plane’s nose. I didn’t notice the torso’s similarity with the nose before I compared it with the plamo of Shiranui Second Phase 3, in which it comes out better due to the white accent line running at the top.
Ultimately, the YF-23 is rather light on the plane elements compared to some of the other TSFs. Some of them have a miniature plane sitting on top of their head, or at least the cockpit bubble, but with YF-23 only major elements were used. It may also help that the real YF-23 is overall featureless outside its silhouettes, which also explains why the TSF’s shoulder units are so busy compared most of the body. However, the shoulder units are also the point where you can see some elements of the overall plane design in the angle/smooth juxtaposition, but this may be just my eye trying to find something that’s not really there. That is actually a danger with this ‘series;’ as everything is more or less done with observations rather than first degree source, this all ultimately is nothing but fan speculation.
If you have any comments what should be changed and/or corrected, or suggestions otherwise, feel free throwing some on the comments section. If it’s something I can do and have enough time, I aim to make those changes. Time is essential to me at the moment, so don’t expect another chart too soon.Of course, if you just want me to stop, you’re free to say that too. This has been a long standing project, but I tend to play the long game with some matters.
As usual with any charts, there are bound to be revisions. These charts actually take about two or three times longer to make, because I tend to check and recheck what I do, and ultimately forget to spell check. Next to that, I decided to add all source pages I used, because that’s one way you can call me out and see how badly I edited the images out from their initial photos.
