I work in an area called export compliance. Essentially, the government has a list of items that are controlled for national security purposes. A specific call-out is US Naval vessels.
These “subs” were built by the same company that built the navy nuclear subs at the same time, the wiring was done by the same company that wired the subs, shipmen were on duty, and a US admiral was involved in production.
It’s more of a esoteric, splitting of hairs sort of thing, but I was looking for a “fun” fact to talk about in my area(it can get dry). I was listening to Disney Dish when they mentioned the submarines and how they had to be decommissioned because they were US Naval vessels. This would automatically make them export controlled, even though their capabilities were limited. It just kind of sent me down this rabbit hole(with a lot of help).
Unfortunately, it doesn’t seem like people in my field are as interested as I thought they might be, but I want to ultimately write something up. In my field, if this fact pattern were to occur today, we would take a long look at the circumstances and try to figure out if we needed special permission to proceed. It’s just really interesting to me(because I am a nerd), that these subs share more in common with a nuclear sub than I think anyone would have considered.
