JSFfan,
The point is as follows.
1. THe USN has accepted that the JSF internal jammer will be incapable of meeting the Day 1 threat by 2020 (prior to IOC) and that the NGJ is required to provide EW cover to penetrate enemy defences.
2. The NGJ integration with the JSF
has been deferred indefinitely - which will, therefore require an escort jammer - either F/A-18G, UCAV or other.
3. Any partner nation not buying/ being allowed to buy the NGJ loses the Day 1 capability rendering the stealth aspects of the JSF of little or nugatory value.
It would be interesting to compare the cost and capability of a mixed F/A-18G + F/A-18E fleet versus an 18G/JSF and, for other partners such as the Dutch, Turks etc a Rafale/Typhoon/F-15E force fitted with NGJ for self protection.
