A serious question here: what history are you drawing this inference from? Popular history tends to be a distorted view of history that willfully ignores evidence to the contrary to tell a good story, and military history especially tends to fall victim here. As a good case in point, take WWI. In popular history, WWI is a war of unimaginable destruction because generals were idiots fighting Napoleonic-era tactics wit…

Any historical claim can be argued with, and I guess this is an example, but I would maintain that WWI involved a lot of things that wouldn't be repeated with modern knowledge. To offer another example, consider actual Napoleonic-era tactics: why was Napoleon running around and defeating everyone with them when the same guns were basically available everywhere? Ideally everyone would have copied his artillery tactics…

More prosaically, Napoleon had much larger armies available to him than his opponents: "You can't stop me, I spend 30000 men a month" [1].

True, thanks. But in this case it was a fortunate fluke. Their queue is probably pretty long and unresolved as we speak.

It... doesn't really work

It was a typo, I acknowledged it, and made a joke. ¯\_(ツ)_/¯

This was not a fluke. The failure rate of large scale IT projects is the huge. For large, complex projects the statistics is 2% success 42% challenged 56% failed https://www.standishgroup.com/sample_research_files/CHAOSRep... The new system has probably similar 50% change for success. I think giving the new project to the same contractor may improve the changes. Hhey have hopefully learned something.

Hack: Start development of n systems in parallel, to get 1-(0.98)^n success probability.

This has been proposed and it seems like a credible strategy. The actually implemented versions seem to always end the competition phase relatively early so they are not very good experiments for validating the idea.

It's such a good corporate welfare program that it produced an actual good aircraft.

It's more worker/voter welfare than corporate welfare. Socialism for the middle class. Lockheed Martin's long term profit margin is around 6-7 percent (recently above 9%). Lockheed pays more wages than it makes profits. If you count the whole value chain, with contractors and their subcontractors, it's probably something like 50% total worker compensation (wages, benefits), 10% profits, 10% cost of capital, rest is t…

Trickle-down economics?

How do you get EMP bursts powerful enough to do that?

Yeah that's my point. If the vulnerability relies on nukes then is it even a vulnerability? If nukes are being exchanged that's game and it's a moot point.

Is it? I thought about it like that for a long time also. But nowadays i think think this thought applied to the 'city killers' on or slightly above ground only.

OTOH there are many satellites up there whose missions are unknown (to us). Who is to say that some party wouldn't try it, maybe during a geomagnetic storm? Or, maybe some crazy like NK because, hey, got china watching my Six!1!! Of course the orbits, and therefore the owners are known.

This does not need to be 'high tech' in the way some understand rocket science or reentry vehicles to be. Just some crude device which survives start and waiting 'up there', then being ignited later, without the complications of reentry heat and burn.
