Electronic Stew
Baghdad's toxic electromagnetic environment may foil F-22

The stealthy Raptor fighter and intelligence-gathering aircraft is
ready for war, but probably not the war we've got, says Air Combat
Command's chief, Gen. Ronald E. Keys.
Essential electronic surveillance systems may be too
sensitive--overwhelmed by the density of U.S. and allied
emitters--to be useful in the electronically polluted environment of
Baghdad, the main focus of the new U.S. military surge.
"If war breaks out, I'm sending the F-22," Keys told Aviation Week &
Space Technology last week. But not for operations in Iraq or
Afghanistan. "I didn't buy the F-22 for Iraq. We're looking for what
can sop up intelligence, reconnaissance and surveillance [ISR] in
Iraq and Afghanistan. Is the investment [of sending the F-22] worth
it? Is it a good idea or just an attractive idea? Will it complicate
the air component commander's problems for no gain?"
Keys is not yet convinced and the interference problems are growing.
"Right now we get into situations where we jam against improvised
explosive devices (IEDs) and it corrupts our radio traffic [and]
some line-of-sight UAV operations," Keys says. "It's tough."
The intense jamming may degrade, perhaps blind, some key F-22
electronic surveillance sensors when operating around the capital
city. But some F-22 supporters contend that prediction of the
Raptors vulnerability is being overstated and its capabilities "are
sophisticated enough" to ensure that it will still be a valuable
intelligence-gathering platform, says a senior Air Force official.
Those with insight into the program say the problem is not in the
F-22's capabilities, but that they've not yet tested the Raptor in
such a dense environment and codified the necessary concept of
operations and tactics . However, they point out that the aircraft's
entire electronic surveillance capabilities can be fine-tuned during
mission planning. "They can filter in the frequencies they don't
want to work, eliminate those that are being jammed, specify scan
rates and frequencies and how often they hop between them," says one
specialist. "You can exquisitely tailor each mission."
Nonetheless, Keys is not yet convinced that there is enough added
value to merit sending F-22s from their new, forward base in Okinawa
to someplace in-theater--possibly Al Udeid AB, Qatar, where many
allied intelligence aircraft are based.
There is a need for more airborne intelligence gathering in Iraq,
Keys concedes. The decision point will be whether the F-22 can do
something that's not already being done or do it faster or with
greater resolution. "Would I be better off sending more RC-135
[Rivet Joint signals intelligence intercept aircraft] down there?"
he asks. "That's the discussion going on."
Keys is known by both his critics and supporters to be practical to
a fault. He is not swayed by promises of technological
effectiveness, but instead demands that it be demonstrated. That
hasn't happened yet. There also appears to be reluctance within the
Pentagon to the idea of operating F-22s in a war against insurgents
when the fighter is optimized for cruise missile defense and
long-range offensive and defensive air-to-air combat.
"A lot of people say we don't need the F-22 in Iraq," Keys says.
"That's probably true." His reasoning lies in the classified
strengths of the aircraft and its possible weaknesses in the war
against insurgents. Fighting irregulars effectively depends on
accurate and rapid intelligence collection--one of the things the
F-22 does best.
"The only application [for F-22 in Iraq and Afghanistan] would be
ISR," Keys says. "That would be the supposition for sending it." But
a possible vulnerability in the stealth fighter's legendary
electronic surveillance system--located in the leading edges of the
wings and vertical tails--became apparent during operations by the
first operational squadron flying in the Chesapeake Bay area. The
strong radars on nearby Navy ships were overwhelming the delicate
sensors.
"You've got to tune down the [ESM sensors'] sensitivity," he says.
Making such corrections is "one reason it's a software-[run]
airplane. I don't think it's a fatal flaw, but we now realize that
in some situations we may not be able to see some of the
[intelligence] we wanted to because we simply jam it off the air."
The primary source of that interference is the jammers that have
proliferated to foil IEDs that now cause 70% of the U.S. casualties
in Iraq.
"I don't see how [the F-22's electronic surveillance system] can be
used there," Keys says. "I've been operating [in Iraq and
Afghanistan] since the war kicked off with Rivet Joints, and they
haven't figured it out. They have a lot of people sitting in the
back-end with lots of analyzers, and they're still trying to read
[communications] traffic through jamming."
The problem appears to be one of electronic command and control and
giving authority to someone who can make the call about when to jam.
That's an explosive subject, because jamming is invariably being
used to save lives.
There is a burning need for a joint entity to police the battlefield
and bring organization to the jamming, they say.
"We have to have more visibility of what's going on and where," Keys
notes. "Right now we don't. We didn't anticipate there was going to
be this level of jamming. Every patrol is out there with personal
jammers. We've got lots of airplanes that are also jamming. At the
same time, we've got people trying to listen [to insurgent
conversations], a lot of it on the same or overlapping frequencies."
Air Combat Command officials describe the electronically toxic
battlefield as a big, emerging joint problem.
"Now the [jamming] density has increased as have the number of
people doing it that are out of command-and-control range," Keys
says. "That's a problem that has to be solved. I think we probably
need to take a step back to the old way we used to control air
operations--procedures. We're going to have to tie our larger
operations into electromagnetic ops."
A decision Keys does support is the deployment of more MQ-9
Predators with their greater payload, faster speed and higher
operating altitude. The increase is hampered by the bottleneck of
adequate crews and UAV cockpits at Nellis AFB, Nev., control center
for operations in Iraq and Afghanistan.
"Our intent is to stand up [MQ-9] orbits as fast as we can," Keys
says. "We think we have a couple of extra birds that we've got the
[capability] to man and control. I think we're planning to go to
four in-theater." The Air Force's UAV base is at Balad AB north of
Baghdad. He also notes that the cockpits have been upgraded so each
UAV crew can now control two UAVs simultaneously. However, the
original goal of flying four UAVs at a time from a single cockpit is
still considered over-reaching. "That's too many," he says. The new,
larger Predators are going to carry a full load of sensors plus
"four Hellfires and two 500-lb. bombs."
