The Typhoon, as of right now, holds exactly one TRM, because it's a classical radar. AESA radars are arrays of "mini-radars".There is no rumours it's a fact the typhoon holds bigger amount of trm modules
Now, here's some food for thought: you know the property of a cone is that it's smaller as you get farther away from its base, right? So if you need a bigger diameter, you can make a bigger nose, or you can make a thinner radar. That's where cooling technology enters the picture. Radars generate a lot of heat, and if you don't want them to self-destruct by melting, you've gotta cool them continually. The cooling system takes a lot of volume, in addition to the volume of the radar plate itself. And of course, it needs to be just next to the radar plate, it can't cool it from the other end of the aircraft.
If you go for a big gizmo with a mechanical system to change your antenna's position, you're wasting a lot of volume and negating the advantage of your bigger nose. But that's not all: you still need your dish to have room for pivoting, so you're wasting even more volume for this. The result is that the fabled CAPTOR-E, if and when it actually happens, will not have more TRMs than the RBE2. The RBE2 is already at over a thousand TRMs, by the way.
And that radar is comparable in performances to the RBE2 PESA... As seen is exercises with the F-16 bk. 60 of the United Arab Emirates. That makes them greatly inferior to the RBE2 AESA, whose range is double that of the RBE2 AESA.even the f16 apg 80 holds more trm modules.
On that topic, it may be interesting to recall an anecdote. The first RBE2 AESA prototype was made with American TRMs. From the performances of this prototype, it was expected the RBE2 AESA would be 50% more powerful. But when actual RBE2 AESAs were made with French TRMs, the performance gain was not +50% but +100%. Does that mean that the USA sent downgraded elements deliberately, perhaps fearing industrial espionage, or does that mean that American technology isn't all that it's cracked up to be? That's not a question that can be answered with certainty, at least on public forums, given how all this sensitive stuff is classified.
