I’ll add that BAE Hugglands regularly refuses stuff like local production etc in bids made by BAE, unless BAE starts pulling teeth etc. BAE Hugglands is pretty much operates as its own thing.
It’s specifically built by General Dynamics UK. The whole subsidary thing means it’s under a different company which in this case makes it a British subsidary of a US company. Hence why it’s literally called General Dynamics UK
General Dynamics UK is owned by General Dynamics. It’s the same company just different for tax purposes.
Same thing is done for BAE.
There is no difference, both do their methods exclusively for tax purposes.
There’s a bit more to it than just taxes, it’s also to some extent political benefit. General Dynamics UK encompasses quite a few originally UK companies though and as such while it is indeed owned by General Dynamics it is still a UK subsidary and as such is run as it’s own company. Just that General Dynamics gets to boot the brass if they aren’t happy with the profits.
The point still stands that it’s a UK subsidary of an American company. Just like BAE Hägglunds is a Swedish subsidary of BAE Systems
