I said bought, not use. The aircraft inventory for the U.S. Navy and Marine Corps are one, bought by one organization, managed as one. For that matter look closely at Marine aviators, they wear gold wings because they are Naval aviators, not bus drivers. Forgot India and Italy, should have remembered them. Did Spain ever get any/many AV8Bs, there was a case to sell them but the cost was high and they were unsure whether to go with it?
