Am I just too ignorant of Miltech, or is this that in large parts recreating Standard messaging primitives that other protocols and systems have been providing for decades already (so invented elsewhere?)

DDS sort of took over from CORBA in the military domain, and the statically-typed IDL was still quite similar to CORBA last time I looked at it, so that takes you back to around 1998 when CORBA was being used a lot in the military in my experience.

What other protocols and systems were you thinking of that can provide (depending on broker) hard-realtime delivery that can be used in safety-critical systems?

Every mil company designs unique bespoke things often with some exceptions, and even the "open systems" mostly aren't open by any stretch of the definition.

Obscurity is part of the allure, not a repulsive factor.

You don't want a hostile nation suddenly and easily understanding your systems.

On the other hand, its good to design systems where it wouldn't even matter if the hostile nation state knows exactly how it works.

This is a principle in cryptography, but carries nicely to other things.

		I feel like this is always the best design whenever possible.

I have to assume that so many people require access to the specs that an interested party can surely acquire them.

World of Tanks has repeatedly had military personnel updating the technical specifications with details they have found in the secret manuals.

Asterix is an actual standard for radar data, coming from civilian radar systems. I wish it was updated somehow for 3d beam-steered (and moving) sensors, but still it covers most of the industry's needs... I keep hearing so many grumblings of replacing it (it is binary, unforgiving, quirky, very 80s...) and of course fragmentation is back in.

Hat sounds like a particularly weak form of security by obscurity

Also you do not want them to benefit from your smart design choices. You want them to suffer from their bad choices and not learn from your success. (Yes, of course you could have bad design choices that you don’t realize someone else has solved more intelligently.)

		Bad design choice is probably why they open sourced it.
