In case someone reads this comment and wonders what the actual names of this aircraft are:

The official name is the F-35 Lightning II Joint Strike Fighter. It comes in three variants:

* F-35A (Conventional TakeOff/Landing - CTOL)

* F-35B (Short TakeOff/Vertical Landing - STOVL)

* F-35C (Carrier Variant - CV)

While an unofficial nickname hasn't solidly grabbed on, I think, given that USAF Fighter Weapons School calls it the "Panther", that will probably be what holds at least in the US.
