If these boats are built they'll be built under a commercial contract. There will be no mid-contract goal post shifting which is usually the case once un-informed uniformed ruperts get in over their heads with ideas of moving from RN to Bae post contract.
If these boats are built they'll probably be owned and operated by a trusted "partner", think SERCO. They already operate most RN in port support vessels, and a few deep sea vessels.
If these boats are built they'll probably be laid down at a a Romanian or Turkish yard, probably with a massive input from an already respected supplier of govt vessels.
