DARPA: With Insights from Integration Exercise, SubT Challenge Competitors Prepare for Tunnel Circuit

Nine teams hailing from four continents gathered in Idaho Springs, Colorado, the week of April 5-11, 2019, to test autonomous air and ground systems for navigating the dark, dangerous, dirty, and unpredictable underground domain. The SubT Integration Exercise, known as STIX, took place at the Colorado School of Mines' Edgar Experimental Mine. The event provided a shakeout opportunity for competitors in advance of the Tunnel Circuit in August, the first of three subdomains that teams will tackle in DARPA's Subterranean Challenge.

The teams were divided into three groups. Each group had one day to experiment with their various systems during multiple runs in the mine, followed by a second day in which each team attempted a one-hour mock, scored run. Teams could earn points by accurately locating, identifying, and reporting artifacts placed within the tunnels. Artifacts included thermal manikins, backpacks, fire extinguishers, cell phones, and cordless drills – all inspired by objects an end user such as a warfighter or first responder might encounter.

The mine environment presented teams with low light, high dust, metal rails, and irregular terrain. The DARPA team added to the complexity with a theatrical smoke machine, which mimicked real smoke a warfighter or first responder could contend with in an emergency response scenario, for example.

“It was amazing to see the progression from day one into day two for each team as they explored the tunnels of the mine and began to understand just how complex and unknown these underground environments can be,” said Timothy Chung, program manager for the Subterranean Challenge in DARPA's Tactical Technology Office. “It's not just about testing whether there's enough light or if robots can drive a few meters. It's about how all that has to come together in a difficult environment and the teams are experiencing the challenge of integration in addition to technology development.”

The competitors at STIX included a mix of DARPA-funded and self-funded teams:

Following the Tunnel Circuit, teams will compete in the Urban Circuit, which will focus on underground urban environments such as mass transit and municipal infrastructure; and the Cave Circuit, which will focus on naturally occurring cave networks. Locations for the circuit events have not been announced.

Qualification is ongoing for the circuit events. Requirements can be found in the SubT Qualification Guide available on the Resources Page. Teams interested in joining either the virtual or systems tracks can still register and are encouraged to join the SubT Community Forum to exchange ideas, explore teaming opportunities, and receive updates on the Challenge.

    US Should Pull Drones From Missile Control Regime: Mitchell Institute

    "I have great hopes that this administration, with its bold unilateral actions on so many fronts, would take unilateral action with this regime on UAVs," says Keith Webster, former DoD head of defense cooperation. By THERESA HITCHENSon June 03, 2020 at 12:48 PM WASHINGTON: The Trump administration should unilaterally declare that it will no longer subject drone sales to export control restrictions under the Missile Technology Control Regime (MTCR), says a new Mitchell Institute study. And Congress should use the 2021 National Defense Authorization Act (NDAA) to redefine unmanned aerial vehicles (UAVs) as aircraft, which not only remove them from MTCR restrictions but also would ease US domestic export controls, asserts the paper, “”Modernizing UAV Export Policy for Effective Coalition Forces,”. “The US Congress should craft language in the 2021 NDAA that defines UAVs as aircraft, not cruise missiles, but as aircraft, and subject to the same export considerations as any other military aircraft,” said Heather Penny, senior resident fellow at Mitchell and the paper's author, during a webinar today. “We believe that this language, a statute, would be sufficient to be able to remove UAVs from being subject to the MTCR guidelines.” The 35-nation MTCR agreement requires a “strong presumption of denial” for sales of so-called Category 1 drones — those that can carry a 500 kilogram payload more than 300 kilometers. The Category 1 definition is considered as the minimum capability a missile needs to carry a nuclear warhead. Smaller unmanned aerial vehicles also are covered under MTCR's Category 2 rules, but those export restrictions are less stringent. Even the treaty-hating Trump administration sees the MTCR — a political agreement rather than a treaty — as a key tool in preventing the proliferation of ballistic and cruise missiles. This is despite its long-standing efforts to ease drone sales to allies, including through revamping US domestic law to allow “Direct Commercial Sales” by companies, rather than requiring all sales to go through the formal Foreign Military Sales process that requires approval by DoD, the State Department and Congress. Indeed, over the past year the administration tried — and failed — to convince its MTCR partners to revamp the rules to allow drones flying less than 800 kilometers per hour to slip out from under the Category 1 rules, said Penny. Washington is now expected to try again at the annual MTCR signatories meeting, she said, instead suggesting a 600 kph speed limit as the line of demarcation between the two categories of export restrictions. (The meetings are usually held in the fall, although there has yet to be an announcement of the 2020 dates.) But, Penny argued, even if this new effort comes to fruition, it would fail to fix the underlying problem of allowing allies to buy high-end US combat drones — and preventing them from fully integrating with US operations. Secondly, she asserted, complying with MTCR rules “distort the market” in favor of Chinese sales, she said, since China is not a member of the MTCR and has few formal restrictions on arms exports. “Continuing to adhere to and apply MTCR guidelines to UAVs facilitates Chinese strategic interests,” Penny said. “It's working against US interests.” Keith Webster, former DoD head of defense cooperation, agreed — calling efforts to revise the MTCR as a “Band-Aid” that would soon loose viability because of the rapid pace of technology improvement. “I wish we would act unilaterally,” he told the Mitchell Institute webinar. “We have the ability to act unilaterally. And I would like to see us do so very soon. I have great hopes that this administration, with its bold unilateral actions on so many fronts, would take unilateral action with this regime on UAVs.” That doesn't mean, Webster hastened to add, pulling out of MTCR itself. “Stay in the MTCR,” he said. “It served its purpose.” The experts acknowledged that a unilateral US move to exempt UAVs from MTCR could spur other nations to do the same for their own weapons systems that could exacerbate nuclear proliferation. Penny stressed that it was key for the US to renew its commitment to nonproliferation of ballistic and cruise missiles, and support MTCR's rules for those systems. Saying that “we need to be honest with ourselves about the implications” while seeking “creative solutions” to the UAV issue, Webster seemed to suggest that ultimately the US may decide the MTCR itself isn't worth the trade off. “There are challenges with compliance within the regime with at least one member,” he warned. As Breaking D readers know, US military leaders and Congress have sounded the alarm on the proliferation of cruise missiles by Russia (an MTCR member) and China that can more easily slip through US ballistic missile defense systems. This is especially true for hypersonic missiles, which have speeds above Mach 5 and while visible on radar are extremely hard to target. https://breakingdefense.com/2020/06/us-should-pull-drones-from-missile-control-regime-mitchell-institute/

    Coronavirus drives AFA’s massive Air, Space and Cyber conference online

    Stephen Losey The Air Force Association announced Monday that it will hold its massive Air, Space and Cyber conference virtually this September, due to the coronavirus pandemic. AFA's annual conference typically draws about 12,000 airmen, civilians, contractors and other attendees to National Harbor, Maryland, and features addresses from major Air Force, Defense Department and industry figures. For the first time this year, the virtual conference will feature a combination of live and on-demand conference sessions streamed online, beginning Sept. 14 and lasting at least three days. The events will include live addresses from senior leaders, and will allow viewers to ask questions and engage in other “unique opportunities ... with Air Force, Space Force and industry leadership,” AFA said. There will also be a virtual exhibit hall to display developments and demonstrations from industry, online meetings and interactive presentations, AFA said. Retired Lt. Gen. Bruce Wright, the president of AFA, said the decision to move the conference online was “extremely arduous.” But with the pandemic still ongoing, he said, it would not be possible to safely host a conference in-person of the quality the association desired. AFA considered Centers for Disease Control and Prevention guidelines, state and county directives, and feedback from potential speakers, attendees, sponsors and exhibitors. “Our goal is to continue AFA's long tradition of hosting the premier event for defense and aerospace professionals around the world,” Wright said in the release. “Our virtual Air, Space and Cyber conference will offer the same exceptional line-up of speakers, world-class exhibits, professional development opportunities, and networking opportunities for industry, government, media, academia and the public.” Air Force leaders often use their addresses to the AFA conference to make major announcements, such as former Secretary Heather Wilson's 2018 “Air Force We Need” address laying out a plan for a major expansion of the service's operational squadrons. Past speakers and guests at AFA's conference have included the top leaders of the Air Force, defense secretaries such as Jim Mattis, and Tuskegee Airman Charles McGee, who last year helped unveil the name of the T-7A Red Hawk. Staff Sgt. Spencer Stone, the airman who charged a knife-wielding terrorist on a train in France in 2015, also was celebrated at the conference that year, when the Air Force announced he would be promoted two grades for his heroism. https://www.airforcetimes.com/news/your-air-force/2020/07/06/coronavirus-drives-afa-s-massive-air-space-and-cyber-conference-online/
