That EADS press release indicated that wet transfers had been made between the Airbus boom and a Portuguse F16 - that would be a F16 Falcon made by GD/LM and unless the 'guesies have modded their receptacles, it'll be the same as the receptacles on USAF F16s - hence a US standard.
Now unless the Seppos are planning to change the boom receptable standards on their next generation of fighters, logic suggests to me that if it fits a Falcon, it'll fit an Eagle, a Raptor and a JSF.
But that's logic and this is defence procurement we're talking about...
Did anyone else see the irony in the RAAF's first Airbus MRTT having the c/n '747'?
