Here's a quote from the Dec 07 Journal of Elecronic Defense (their spelling!).
It is from a bloke way up in LM and it seems to prove that you need more than just the Sonderwaffe F-35 in your airforce if you want to fight anyone with an IADS:
From Neil Kacena, Lockheed Martin’s Vice President for Advanced Development Programs, on the current limitations of stealth:
“There was a time when stealth was good enough [to allow US aircraft to penetrate an integrated air defense system]. That time is gone. In fact, I would suggest that there’s not a single capability out there today, on its own, that’s going to grant survivable access and mission effectiveness. A marriage of low-observability, airborne electronic attack [AEA] and a net-enabled capability is needed to achieve high levels of survivability.
Sounds to me like an accidental Lock Mart endorsement of the requirement for the B-Word EA-18G...Take note enquiry members!!!
