This is Called Circling the Drain

It looks like yet another capability is being removed being removed from the JSF (Paid subscription required):

The F-35 Joint Strike Fighter, long touted as the follow-on to the EA-18G Growler electronic attack aircraft, is no longer heir-apparent as the king of nonkinetic warfare.

The often-delayed Lockheed Martin JSF program is being more narrowly focused on its conventional attack role. Jamming is no longer a priority for the stealthy fighter. The airframes expected to carry the Next Generation Jammer (NGJ) are conventional-signature unmanned aerial systems and will be followed by stealthy unmanned designs.

One of the sales pitches for the JSF was that it's engine, because it carried a lot of extra hardware to drive the lift fan, which would have allowed for it to be a stealthy platform with a few dozen megawatts of capability.

The can't make the program work, so they are removing bits to ease the cost, weight, and schedule issues.

It will eventually enter service, but it's going to be a lot less capable than it has been billed.
