... and then the contractor turns around and gives you China-built parts and US-built software to run them, with little meaningful independence gained.

The industrial world by now is too globalized for this sort of approach to work. We keep pretending otherwise so that money keeps flowing and the general public doesn't freak out, but I bet even the almighty US cannot certify that most of their tech is built at home.

Probably only the shit that matters. The nuclear weapons, first and foremost, and then an exponential decay in validation as you get less and less lethal.

I gotta figure the F-35 is cover for several substantial black budgets at this point, and that it's actually much cheaper than the paper trail would have us believe, simply because I remember reading about the presumed obsolescence of manned warplanes back when the YF-22 and YF-23 were battling for the F-15 replacement program, before the F-22 won.

My rationale being, if pilots are worthless in airplanes, then it doesn't actually matter if the program is properly funded, and it becomes an ideal smoke screen for time and effort diverted elsewhere.

I became even more convinced when I found out the F-22's and the F-35's avionics both were controlled over a firewire bus.

...and what problem would a firewire bus seem to indicate?

(But overall I'd agree that the widely trumpeted F-35 blunder is kind of a PR stunt from the US military for the rest of the world: "look, we've just spent so many billions on top secret military capabilities you know nothing about, so we have super dope secret weapons that will blow you up, and we believe your spies aren't even competent enough to figure out that our secret programs exist, let alone what they do, so we'll "silently" have to brag about labeling it as "spending blunders" for it for some deterrent value"... the problem with this shit is that such an international mil policy strategy with it's possible strategic implications sounds like the prequel of an Apocalypse/WW3 movie... so let's hope this is not the closest variant to the truth or we're all fucked)

Mostly, the use of a standard interface like firewire (IEEE 1394) seems to hint at economical choices being made somewhere in the supply chain, in that it probably allowed lockheed to source off-the-shelf parts, when wiring up the planes and loading software packages.

They didn't spend extra to develop or patent custom avionics superior to civilian technologies, or even try to lock secret intellectual property into the designs, to create a barrier around the fly-by-wire systems. This is a rare event when it comes to corporations interacting with government programs. Especially when fielding niche high technology line items with decades-long lifecycles.

Whether it was stipulated as part of the government program or one of lockheed's design decisions, there's a sense that the economical option provides breathing room for false compartments, without reducing superficial complexity.

Defense contractors talk a whole lot about COTS (commercial off the shelf) these days (and in the past few decades). It's a big deal to be able to not spend money reengineering something equivalent to an existing technology. It would take _years_ to create a new data comms interface (like FireWire, USB 1,2,3, ThunderBolt, etc etc) and why? The signaling physical layer and cabling design don't need to be redone do they?

They'll surely have reengineered cables and connectors to survive the aircraft environment, but who wouldn't rather buy a FireWire PHY from Mouser than design and manufacture something similar from the ground up?

Decisions like this will have happened at Lockheed and high up / early in the design phase. (i.e. it's not some subcontractor finding efficiencies but a fundamental block of the system design)

And they even got foreign governments to chip in.

It's not as hard as you think, the contracts and governing laws are big and complicated governing who can do what and know what which is part of why things are so expensive.

The primary business of being a defense contractor isn't building things, it's interacting with the government and farming out work to other companies. A whole lot of that is just compliance.
