I do not have time to post snippets / intros to the following articles, but as I found them all interesting and relevant to the present topic, I plonk them here. (They may appear elsehwere on this forum, but then here they are again.)
In August 2020, there was a large USAF test exercise in Nevada involving multiple stealth platforms: F-22, F-35, B-2, RQ-170, possibly other unnamed platforms:
Stealth Is Put To The Test In Huge Exercise Teaming RQ-170s, F-35s, B-2s With Other Jets by Trevithick & Hunter @ TheDrive.
A few months later, B-2's exercised with F-35's out of Luke AFB in Arizona. Why no F-22's? Dunno. Maybe IFDL meant the Raptors couldn't play with the other children in the sandbox and the first exercise showed it was too hard to integrate them? Speculation on my part. Another article at TheDrive, this one by Newdick:
B-2 Bombers Practice Stealth Team Tactics With F-35 Pilot Trainees For The First Time.
An article mentioned in one of those two stories discusses military aircraft and their data-links (specifically Link-16 and something called SADL, both not being stealthy). Conspicuously absent was discussion of MADL:
Master Chart Showing US Military Aircraft And Their Data-Links Includes RQ-170 SentinelThis article about
The B-2 Bomber Is Still Getting “Game-Changing” Upgrades As Focus Shifts To The B-21 mentions comms, and kinda/sort hints at MADL, if reading between the lines, but no specific mention is made. It does reference this article about using the B-21 as a high-altitude BACN node:
The B-21’s Three Decade Old Shape Hints At New High Altitude Capabilities, which would imply a MADL capability would have to exist -- OR -- you have to add some other LPI / stealthy comm capability to F-35 and all your other tactical theater-level assets.
Lastly, this article discusses
Air Force Upgrades Weapons, Radios for B-2 Stealth Bomber, but it focuses more on some low frequency, EMP-survivable strategic comms capabilities. Still, all signs seem to point to MADL having been added to the B-2, and having that capability as a B-21 requirement.
Can someone refresh my memory -- why was it so difficult / expensive to add MADL to the F-22 that it was dropped? Being that all comms these days seem to revolve around SDRs... why was adding MADL to F-22 so difficult? Wouldn't it just have been some software changes to make the SDR hardware do different magic tricks? The fact that it was not done suggests a hardware mod or addition would have been required to the F-22. This suggests to me that it is more than just "waveforms"... that different frequencies are involved, so different hardware emitters/receivers are required? MADL is Ku band, so I am inferring that IFDL is NOT Ku band?
Also, can someone point me to a primer on "
waveforms"? To this air head, a "waveform" is just a sine wave, and I am obviously not grokking the finer points of this topic. TIA.
