Well believe it or not RBE2 and J/apg-1 are actually older then CAPTOR. Now Captor has much more range then either. Has RBE2 is supposedly a bit outraged by the Radar on the mirage-20005 and the J/apg-1 is somewhere between apg-66 and 68, but neither of these were built as air superiority fighters. The RBE2 was to consolidate the various radars on the different mirage aircraft into a single unit while the J/apg-1 was built for sea search. RBE2 was started in 1989 and first flew on an actual Rafale in 1993, that same year ECR-90A first flew on a BAC1-11 and I don’t think ECR-90c flew on a DA aircraft till 97-98ish. The engineering model of the J/apg-1 “Future fire control system” first flew on a test aircraft in late 1986, early 1987 and the final model flew on a test aircraft in 1991. Notably the French Navy’s Super Entendard had a PESA starting in 1994 (Anemone) which might have been used in modified form from a French hornet 2000 if the Rafale fell through.Yeah but what I said was "at the time", which is well prior to AESA deployment.Well I probably wouldn't mention Captor as a plus point. It's embarrassing frankly that a AESA still, still hasn't been fielded. Soon hopefully.
In fact back in the early 90's, only the Mig31 using a PESA was in service. Let alone when the real decisions where being taken in the 1980's.
No I don't see the RAF being overruled. Heseltine jumped on what was I think ACA at the time, but it was firmly rooted in requirements. Which is why it has survived to service.
