Stealth aircraft are not even a major technology, it’s just one of many thousands of technologies in our modern life which has neither a corresponding branch of science nor a field of engineering.
Hmm I think you’re underestimating how important it is with “one of many thousands of technologies.” Regardless I don’t think the semantic debate is too important.
The main limiting factor in developing stealth airplanes were materials:
This is very much false! Materials historically contribute like 1 OOM while shape contributes 3-4 OOMs to the radar signature.
ignores the fact the geometry of modern stealth fighters generally have no more flat surfaces than modern non-stealth fighters
This is a misreading. I alluded to PTD and discussed it for a full paragraph in the main text and again in both footnotes. I agree I could’ve discussed more the innovations since then but I think I was right to cut it for simplicity (the standard way to introduce stealth is as “low observability technology” and say there are many factors involved in stealth etc etc which leads people to have false beliefs like materials and shape are equally important, and other things besides. I discuss some tradeoffs in a comment).
Re relativity I think the case for special relativity is weaker than the case for general relativity.
I’m not particularly interested in debating the semantic question of whether “informed by narrow understanding” is equivalent to “theory,” or whether this is indicative of the “strawman fallacy.” I will say however that you seem to have misunderstood my post substantially more than I misunderstood your comment.
I believe it’s mentioned by Denys Overholser in Skunk Works. He was the main scientist who made Have Blue/F-117s possible. I’m traveling so can’t find the page number. Unfortunately he died earlier this year so I also can’t ask him why he believed this. However one sanity check you can perform is looking at the radar signatures of spy planes before the Overholser/Skunk Works improvements (which included RAMs and some early intuitively low-observability design choices), and compare that with the F-117.
For example, this report from the Air Force Academy says that “although the SR‑71 was 108 feet long and weighed 140,000 pounds, it had the RCS[radar-cross section] of a Piper Cub.” In other words, the large pre-stealth spy plane developed in the 1960s, had, through many trial-and-error optimizations including RAMs and other design features, the radar signature of a small unstealthed plane. If you include presumed further advances in RAMs by 1980, 1 OOM from materials sounds about right.
In contrast, we don’t know based on public info the exact RCS of Have Blue or the F-117 nighthawk (and ofc it depends on angle), but it’s generally understood to be very low, possibly as low as 0.001 m^2. So 3-4 OOMs additional gain from computed faceting alone fits the sanity check.
This is after multiple generations of stealth measures and countermeasures development! When one side has stealth and the other side doesn’t have either stealth or anti-stealth countermeasures (or doesn’t treat stealth as a factor worth mitigating) I expect the difference to be quite large.
