ICBM
Last time I looked, we haven't committed to any money for the aircraft, beyond the three demo models. We have committed to two ships.
That kind of makes the argument you present spurious, as the way to save capital cost is to kill the aircraft.
If we do buy the aircraft, the costs of QEC refit / crewing will pale into insignificance compared to those of the aircraft.
There is also an element of fallacy in that argument. Cat n trap does not equal one carrier. Cat n trap equals one carrier in the near term - depending on the conversion cost (the real one), there may be two ships, particularly as a QE conversion would occur ~ 2022 - outside the current EPP.
