Two-seat Rafales? Wikipedia is your friend:
Initially, the Rafale B was to be just a trainer, but the Gulf War showed that a second crew member was invaluable on strike and reconnaissance missions. Therefore, in 1991 the Air Force switched its preferences towards the two-seater, announcing that the variant would constitute 60 percent of the Rafale fleet
Slightly sloppy language in that quote. As has been pointed out the ‘strike’ (nuclear) role can be carried out by a single-seat Rafale; that’s because the targets are (hopefully!) rigorously pre-planned and tend not to move. It’s dynamic conventional missions such as armed recce and interdiction which increase the challenge for a single pilot.
Remember that Typhoon was treated as a ‘pure’ fighter during its development, so the logic invoked by the FAF would not have applied despite the design decisions being taken in a similar timeframe. Back in those days the assumption was that Tornado would be replaced by something else, so if Typhoon grew into attack roles it would be only as a Jaguar (and possibly Harrier) replacement. Fast forward to F35 development, and improvements in sensor and computing technology saw ‘sensor fusion’ finally displace the second crew member for all mission types. This rather begs the question of Typhoon’s current suitability for the full range of air-to-ground missions, having neither the designed-in sensor fusion of the F35 nor the flexible computing power of a second brain. An upgrade from Litening III will probably be needed to ease the pilot’s task while tracking moving targets, which will need to be done very accurately if Typhoon is to be able to replicate Tornado’s Brimstone capability.
We’ll be unlikely to find out whether sensor fusion is sufficiently mature for F35 to have dispensed with a WSO until the type’s first combat results hit the media. No pilot is going to confess publicly to finding targeting a bit tricky! In the meantime, I was intrigued to see on a recent thread a French-German concept drawing of a stealthy combat aircraft... with two seats!
