WASHINGTON: China is besting the United States in key military technologies
like hypersonic missiles and electronic warfare, Gen. Paul Selva, vice-
chairman of the Joint Chiefs said today. We can still catch up, he predicted
.
What about Artificial Intelligence? That’s too close to call, said former
deputy Defense Secretary Bob Work, so we’d better get a move on. Both men
spoke at a CNAS conference on “Strategic Competition: Maintaining The Edge.
” “I actually regret talking about the Third Offset Strategy, in hindsight
,” Work said, referring to the high-tech initiative he launched in the
Obama Pentagon. “It made it sound like we had the advantage and we had the
time to think about it and go through the motions…. I wish I would have
said, ‘we need to start about upsetting the Chinese offset, which is coming
uncomfortably close to achieving technological parity with the US.’ “At
this point, I would think that the outcome is too close to call,” Work said
. “It’s time for the US to crack the whip. (Let’s) hope it’s not too
late.” Wikimedia Commons Russian Krasukha-2 radar jamming system,
reportedly deployed in Syria Hypersonics & Electronic Warfare So what are
some of these shortfalls? The most high-profile is hypersonics, weapons
designed to move through the atmosphere at more than five times the speed of
sound. Defense Undersecretary for R&D Mike Griffin has made hypersonics his
top priority and has warned that China has conducted 20 times more tests
than the US. China has demonstrated some impressive technology, Gen. Selva
said today, but the race is far from over. “They haven’t mass-deployed
hypersonics or long-range ballistic missiles,” he said. “What they have
done is proven the technologies, so they are able now to deploy those
capabilities on a larger scale. PROMOTED Trapped in the Arctic Ice

We are behind in the demonstration of many of those technologies,” Selva
admitted, elaborating on a statement he made in January, “but we also can
take asymmetric approaches and catch up. We are way ahead in a lot of the
sensor integration technologies” — essential for telling the hyper-fast
weapons where to go — “and we have to maintain that edge.” Sydney J.
Freedberg Jr. graphic SOURCE: DARPA What about Electronic Warfare, I asked?
Detecting, triangulating, and jamming enemy radio transmissions has long
been a Russian strength and is increasingly a Chinese one, while the US
disbanded many of its EW forces after the Cold War. Selva’s answer got into
technical nuances I hadn’t heard before. “We’re a step behind,” Selva
said. “It’s not hard to catch up, but as soon as you catch up the fast
followers will actually leap over the top of you — and that’s the dynamic
that’s set up by having digital radio frequency management capability.”
DRFM, also called Digital Radio Frequency Memory, uses modern computing
power to record enemy radio and radar signals, modify them, and copy them,
allowing forces to transmit a false signal that the enemy can’t tell from
the real thing. It’s a much more effective way of “spoofing” than
traditional analog techniques, which suffered from telltale signal
degradation. “We assumed wrongly that encryption and our domination in the
precision timing signals would allow us to evade the enemy in the
electromagnetic spectrum,” Selva said. Vice Chairman of the Joint Chiefs
Gen. Paul Selva It turns that that timing is everything in EW as well as
comedy. While GPS is now part of daily life, a much less well-known feature
is that GPS requires incredibly precise timing — within about three-
billionths of a second — which can be used for other purposes, such as
coordinating different radios as they switch rapidly from one frequency to
another to avoid enemy detection and jamming. But apparently that wasn’t
enough to evade DRFM-based jamming, which can create a false timing signal
that causes the entire network to fall out of synch. “We took a path that
they have now figured out,” Selva said. “The Chinese and the Russians took
an alternative path, which was to employ digitally managed radio frequency
manipulation, which changed the game in electronic warfare. “We have done
an in-depth study of where we are relative to the Chinese and Russians (
across) the entire spectrum, and we’ve got some work to do,” Selva said.
“We have to figure out alternative pathways for communications and command
and control so it doesn’t have to be an RF (Radio Frequency) game…It’s an
RF game because we chose to make it so.” He didn’t specify what the
alternatives to radio communication were, but there’s been promising work
using lasers to beam messages. (Breaking D readers will remember that we
first reported the demise of America’s lead in spectrum four years ago.)
Securing our communications networks isn’t enough, Work told me afterwards,
because every weapon system now has chips in it that can be hacked into. “
We have focused on securing network communications, but our biggest
vulnerabilities now, Sydney, are in the DoD Internet of Things — the way
you can crack into the network through platforms (e.g. tanks, aircraft,
ships) and through components on platforms,” Work said. “The Russians and
the Chinese understand these vulnerabilities and really try to exploit them.
” So there are really three fronts in cyber/electronic warfare, and Work
isn’t sanguine about any of them. “Dominating the electromagnetic spectrum
, and securing the DoD Internet of Things, and securing networks, all of
these three things, in my view, we’re well behind in,” he told me. The
whole “Chinese theory of victory,” he said, is known (in translation) as
“systems destruction warfare” because it focuses on electronically
paralyzing command-and-control rather than physically destroying tanks,
ships, and planes. Go Master Ke Jie defeated by AlphaGo Artificial
Intelligence Now, artificial intelligence could potentially revolutionize
electronic warfare. Computers can identify signals, trace them, and making
jamming decisions much faster than human minds — a concept called “
cognitive EW.” But that’s just one of the many military applications of AI
, from advising human commanders to coordinating swarms of combat robots.
Robert Work While Selva didn’t address Artificial Intelligence, Work did;
it’s one of his passions and the central theme of the (now deprecated)
Third Offset Strategy. So who’s ahead in AI? Defense Innovation Advisory
Board chairman Eric Schmidt, a former Google AI guru, told Work he had once
thought the US was five years ahead of the Chinese, Work recounted. But
after a recent trip to China, Work recounted, Schmidt changed his verdict:
“If we have six months, we’re lucky.” Schmidt said last year that the US
lacks a coherent strategy to counter the Chinese in this area. The US has
never been in a competition this intense, Work said. China has made AI an
official national priority — something he thinks the White House should do
here — and the Chinese have great coders. The Pentagon is now creating a
Joint Artificial Intelligence Center, something Schmidt’s DIB proposed over
a year ago, Work noted. “We’ve got a lot of advantages and we can do very
, very well in this race but don’t take anything for granted,” Work told
me. Just as politicians are warned never to take victory for granted,
neither should DoD. “It’s a political rule to always run like you’re
losing, and that’s what we have to do in this area….The Chinese are very
clever and very capable competitors, and they’re intent on surpassing us.” | x****o
