Sorry, what does the plastic pig bring to the party apart from "coming soon" folks/pass the hat around (again).
"What's it bring?"
1. Where have you been? The new capabilities the F-35 brings to the battle have been discussed ad nauseam and the tactics to exploit those capabilities are now being developed. Including tactics that use the F-35 to significantly improve the effectiveness and lethality of legacy aircraft still in the forces.
2. The Tornado first flew 38 years ago and has been out of production for nearly TWO DECADES and the fielded aircraft are reaching the end of their service lives. The F-35 is at the very beginning of its operational/service cycle. How much better was Tornado than the aircraft it was replacing when Tornado first entered service? The F-35 brings far more capability at the beginning of its service cycle relative to the aircraft it will replace than Tornado did when it was first fielded.
3. Waiting for all the Tornados to die before developing and bringing into service a new aircraft is stoopid.
...and a WSO to bring it all together
The argument about a second flesh and blood crew member versus a digital computer will likely not be fully resolved in our lifetimes. In any event, the types and number of sensors and the sensor fusion provided by the F-35 systems by all accounts is far ahead of what legacy aircraft can do, even those with a 2nd crew member.
...and then there's the stuff that isn't talked about..
Do you really imagine that there's nothing that "isn't talked about" with regard to the F-35? Or are you saying the Tornado's secret stuff is better than F-35's secret stuff because you say so?
And finally there is the matter of stealth, which the Tornado cannot under any circumstance ever provide. Yeah, I know, "stealth is over rated." Tell that to USAF, USN, Israel, Denmark, and more than a few other national air arms.
