There are some military contractors in Scotland who will probably relocate if they get independence.
They will probably be forced to. The UK is a trusted partner with US Defence firms, and are trusted with a lot of secret US tech that the US Government doesn’t want just any old country to be privy to. This special arrangement would not necessarily be inherited by an independent Scotland (especially a stridently, anti-nuclear, leftist one) and in order to maintain these arrangements with US defence contractors, BAe Systems et all will have to relocate their facilities down south or across the sea into the rUK. Would be good news for England’s defence industry, especially in Portsmouth, thats for sure.
