I can only hope...
...that there is a purchase order for E, F & G model Rhinos.
If there was one truly amphibious force, they could support the Green (or Black for that matter) army wherever and from whichever airfield / CV is best suited.
Ironically the idea of them being 'akin' to the Royal Marines and being equally capable fighting from sea or land is not a bad operational concept. Clearly what was envisaged for JHF.
Their 'rough' field capability has sold enough frames to the Swiss for example - I would conclude that the operational & logistics footprint is nowhere near as big as other FJs.
(It would be nice to see 809 NAS Phoenix tail markings a la Op Corporate)
