Ghostnav,
its not a matter of 'affording it' - we're a £Trillion economy who'se government spends about £500billion a year.
the idea that we 'can not afford' £2bn for C&T and F-35C is mathmatically impossible. we choose not to spend £2bn for C&T and F-35C, and £whatever for LRMPA, and SSN's, and another 20 escorts.
'can't' doesn't come into it.
