Mostly stuff that had just trickled out on Navweaps and industry news and the like, but if you have the team you do they should have tangential awareness - it's popped up enough over the years and I don't think it's particularly contentious at this point. Last one I think related to an SSBN was a Swede boat that I can recall.
My real schooling was an industry event with a fellow who had done his doctoral work in the US (geospatial archaeology, which moved to more practical post-doctoral work in mineral exploration) who was forced to return to Canada and complete his work at McGill after having research stunted under the Invention Secrecy Act.
His thinking was that while oceans are unexplored, anything of note and thousands of tons of displacement was easily identifiable in the perfect contrast medium of vast empty ocean down to a few hundred metres. And he pointed to the resurgence of interest in ICBMs, hypersonic missiles, and even potential orbital platforms in the last decade as a side effect. As it turns out technology designed to detect, catalogue, analyze, and identify disturbances in soil and magnetic anomalies in soil and coastal areas has its uses.
But it makes sense: When medieval era settlement and older smelting at settlements can be identified from orbit via MAD-ish technologies, hope of hiding in oceans seems like a fools errand. The volume of data was previously an issue, but computational power and analysis had risen to the challenge (and I suspect AI these days as well) and it was likely well trodden ground.
On a related note, I suspect that we'll end up finding out in twenty years that much of the AI related "innovations" had been in use in some form for a decade prior in defense or national security.
