Yep. If you don’t have an on premises solution for those industries, you end up making or using an industry specific cloud (see Microsoft, Amazon, and others serving cloud solutions for DOD where there’s enough money to force this).
None of those require on-prem solutions, like at all. I work with those on a daily basis. A basic cloud solution is more secure than most on-prem solutions held together by shitty in-house duct tape made by resume engineers.
Are you really giving navy ships as an example that shows that 'on premises solutions' are not dying out? That would be like saying that plenty of large businesses don't use the power grid because a military ship is self contained. It has no relevance to the current context.
