Something which is maybe 1% or less of the market is not a demand driver in any possible meaning of the word... ;-)
Military/defence has not been a demand driver for a *very* long time, if ever -- it's a follower which takes advantage of the technologies developed (and paid for) by the real demand drivers, which have shifted from PC to mobile and now to HPC/AI.
But even so it doesn't have enough volume/revenue to justify developing custom chips in the very expensive bleeding-edge nodes, things like drones use technology from a few nodes back which is perfectly capable of doing the job and far quicker/easier/cheaper to develop.
Non-drone military applications like traditional planes/missiles/munitions/radar take so long to develop and are needed in such small volumes they're not even a pimple on the face of military demand... ;-)
You are spot on looking at the market right now and historically. But I’m not sure you will be right going forward.
Disclaimer: the following numbers are AI-generated and I do not have the time right now to do the necessary, but tedious fact-checking. Though, the words and opinions are mine.
The wars in Ukraine, Nagorno-Karabahk, Syria and Iran has made it is obvious that large scale drone saturation will be an integral part of warfare going forward.
Based on the current run-rate production of just shy of 10 million drones per year by the warring parties and a per unit DRAM-content of 0.5-4.0 GB, you’re looking on a burn of up to 0.1 pct. of the 2025 bit supply.
That’s not interesting in itself. What is interesting is first, that all frontline states and quite a few on top of that are actively looking at building scaled military drone capabilities across surveillance, deep/mid/short range strike, counter drone etc. including supply depth. We will probably witness quite a build up in places like China, Japan, Taiwan, Indonesia, Pakistan, India, most of the middle east, central/eastern Europe etc. And it’s not only a significant build-up. When you reach scale, there will be attrition due to training, obsolescence etc.
Second, developments in electronic warfare are forcing several drone capabilities towards a higher degree of autonomy, which raises the memory content per unit quite a bit to handle video buffer, map, AI models etc.
My gut feeling is that we see a demand driver of app. 1-2+ pct. of 2025 bit supply in the coming years. In my eyes, this is not inconsequential in a situation where we are witnessing a severe supply gap.
And this is just one use case. We have additional new demand drivers growing in parallel and that comes on top of the gargantuan AI/LLM demand. Not large in and by themselves, but they are typically price inelastic and they arrive at the same time in a very tight market.
Of course, this is pure speculation with several uncertainties.
