Well, here's another rumour to throw into the mill. I was asking one of the mission system designers about this today and was told that some RAF guys had been over to have a look at the CASA's, but he didn't know more than that. It suggests to me that someone, somewhere must be at least considering rethinking the UK's MPA requirement.
Or they are ex-Kipper Fleet looking at jumping ship to help Oman set up it's fleet of 295's
