ISIS and the North Korean regime share at least one tactic in common: both have sought to counter the U.S. military’s monitor-and-strike capabilities by building vast subterranean tunnel complexes. They’re not the only potential adversaries to do so. On Thursday, the Defense Advanced Research Projects Agency, or DARPA, announced a new grand challenge in search of new tech to map, navigate, and search underground.
Tunneling is once again rising in importance as adversaries seek to evade the ever-growing number of cameras and sensors that the U.S. can employ to photograph and collect intelligence on the Earth’s surface. In 2015, ISIS made a practice of attacking buildings, street intersections, and other targets via underground passageways rigged with explosives. “The use of tunnels for IEDs and other purposes will continue to provide a low risk strategic advantage to extremist organizations and therefore requires continued development efforts and fielding of effective mitigation techniques,” according to a 2015 brief from the Joint Improvised-Threat Defeat Organization.
As the war continued, ISIS’s use of tunnels evolved as a means to launch sneak attacks and collect intelligence with cheap drones.
Rukmini Callimachi, who covers ISIS for the New York Times, discussed the Islamic State’s reliance on tunneling with NPR’s Terry Gross back in March. “In all of the areas that I have visited, ISIS dug a complicated network of tunnels. And so what they’re able to do is they retreat inside the tunnels. And then from there, they’re able to send a drone up into the air. So they’re completely protected and unseen from our surveillance. And yet, they’re able to see,” Callimachi said.
Much of North Korea’s weapons development has also taken place underground and away from U.S. sensors, satellites, and spy planes. In 2015, South Korean military leaders said their neighbors to the north may have built 6,000 to 8,000 underground facilities in North Korea, including an 1,800-meter underground runway to launch planes.
“Underground settings are becoming increasingly relevant to global security and safety,” DARPA program manager Timothy Chung said in a taped segment announcing the challenge on Thursday. “Rising populations and urbanization are driving the demand to not only build up but also to build down…subterranean environments have remained an untapped domain in terms of developing breakthrough technologies for national security.” In other words, we need more tunnel tech — and as soon as possible.
“We’ve reached a crucial point where advances in robotics, autonomy, and even biological systems could permit us to explore and exploit underground environments that are too dangerous for humans,” said Fred Kennedy, who directs DARPA’s Tactical Technology Office.
Teams will tackle challenges in human-made tunnels, mass transit tunnels and natural caves. You can compete in a real, physical environment for $2 million or in a virtual environment for $750,000. The final tunnel tech competition will take place in 2021.
