Easy Street said it - Typhoon ECR is an also ran prize for people who don't buy F-35.
an F-35 with a slack handful of SPEAR 3 and SPEAR 3/EW is going to be a far more capable SEAD/EW aircraft than any Typhoon ever built. personally i think we ought to go further and look at the lessons of ALARM vs HARM and develop a high speed, long range, but COST, SEAD missile - we already have a high speed missile body that will fit into the F-35B, lets put an Anti-Radiation seeker and guidence system on METEOR and Bob will be your Mums'
gentleman caller...
the USN are developing the Next Generation Jammer pod to go on the E/A-18G to support F-35C/B operations - the obvious question will be whether it could be operated on an F-35B....
