The Prowler, he added, was designed to support Navy strike operations,
not every service’s strike missions. The upshot is that the fleet is
wearing out faster than planned, creating problems for the airframes,
the electronics, the engines and other basic parts.

“The Air Force did not realize they had to play with EW, but after the
meeting with Aldridge they realize they do.”
....
The service, for example, has a large jamming aircraft, the Compass
Call, based on a C-130 medium-lift cargo plane. “They take a C-130 and
fill them with intelligence officers and jammers. With a large,
non-fighter airframe, range and radiation become a huge issue. ... It
doesn’t matter how big the jammer is, if you are far away it doesn’t
work.” The bigger the jammer, the bigger the radiation problem, he
said.

Don't the same restrictions apply to the EB-52?

So if we must reduce the total numbers of heavy bombers in order to put
a bigger crew than the Growler's at risk, why not a B-1B based jammer?

The Lancer has basic stealth and the ability to run away at supersonic
speed when the situation gets too hot.
