    Army looks for a few good robots, sparks industry battle

    By: Matt O'Brien, The Associated Press CHELMSFORD, Mass. — The Army is looking for a few good robots. Not to fight — not yet, at least — but to help the men and women who do. These robots aren't taking up arms, but the companies making them have waged a different kind of battle. At stake is a contract worth almost half a billion dollars for 3,000 backpack-sized robots that can defuse bombs and scout enemy positions. Competition for the work has spilled over into Congress and federal court. The project and others like it could someday help troops "look around the corner, over the next hillside and let the robot be in harm's way and let the robot get shot," said Paul Scharre, a military technology expert at the Center for a New American Security. The big fight over small robots opens a window into the intersection of technology and national defense and shows how fear that China could surpass the U.S. drives even small tech startups to play geopolitics to outmaneuver rivals. It also raises questions about whether defense technology should be sourced solely to American companies to avoid the risk of tampering by foreign adversaries. Regardless of which companies prevail, the competition foreshadows a future in which robots, which are already familiar military tools, become even more common. The Army's immediate plans alone envision a new fleet of 5,000 ground robots of varying sizes and levels of autonomy. The Marines, Navy and Air Force are making similar investments. "My personal estimate is that robots will play a significant role in combat inside of a decade or a decade and a half," the chief of the Army, Gen. Mark Milley, said in May at a Senate hearing where he appealed for more money to modernize the force. Milley warned that adversaries like China and Russia "are investing heavily and very quickly" in the use of aerial, sea and ground robots. And now, he added, "we are doing the same." Such a shift will be a "huge game-changer for combat," said Scharre, who credits Milley's leadership for the push. The promise of such big Pentagon investments in robotics has been a boon for U.S. defense contractors and technology startups. But the situation is murkier for firms with foreign ties. Concerns that popular commercial drones made by Chinese company DJI could be vulnerable to spying led the Army to ban their use by soldiers in 2017. And in August, the Pentagon published a report that said China is conducting espionage to acquire foreign military technologies — sometimes by using students or researchers as "procurement agents and intermediaries." At a December defense expo in Egypt, some U.S. firms spotted what they viewed as Chinese knock-offs of their robots. The China fears came to a head in a bitter competition between Israeli firm Roboteam and Massachusetts-based Endeavor Robotics over a series of major contracts to build the Army's next generation of ground robots. Those machines will be designed to be smarter and easier to deploy than the remote-controlled rovers that have helped troops disable bombs for more than 15 years. The biggest contract — worth $429 million — calls for mass producing 25-pound robots that are light, easily maneuverable and can be "carried by infantry for long distances without taxing the soldier," said Bryan McVeigh, project manager for force projection at the Army's research and contracting center in Warren, Michigan. Other bulkier prototypes are tank-sized unmanned supply vehicles that have been tested in recent weeks in the rough and wintry terrain outside Fort Drum, New York. A third $100 million contract — won by Endeavor in late 2017 — is for a midsized reconnaissance and bomb-disabling robot nicknamed the Centaur. The competition escalated into a legal fight when Roboteam accused Endeavor, a spinoff of iRobot, which makes Roomba vacuum cleaners, of dooming its prospects for those contracts by hiring a lobbying firm that spread false information to politicians about the Israeli firm's Chinese investors. A federal judge dismissed Roboteam's lawsuit in April. "They alleged that we had somehow defamed them," said Endeavor CEO Sean Bielat, a former Marine who twice ran for Congress as a Republican. "What we had done was taken publicly available documents and presented them to members of Congress because we think there's a reason to be concerned about Chinese influence on defense technologies." The lobbying firm, Boston-based Sachem Strategies, circulated a memo to members of the House Armed Services Committee. Taking up Endeavor's cause was Rep. Seth Moulton, a Massachusetts Democrat — and, like Bielat, a Marine veteran — who wrote a letter to a top military official in December 2016 urging the Army to "examine the evidence of Chinese influence" before awarding the robot contracts. Six other lawmakers later raised similar concerns. Roboteam CEO Elad Levy declined to comment on the dispute but said the firm is still "working very closely with U.S. forces," including the Air Force, and other countries. But it's no longer in the running for the lucrative Army opportunities. Endeavor is. Looking something like a miniature forklift on tank treads, its prototype called the Scorpion has been zipping around a test track behind an office park in a Boston suburb. The only other finalist is just 20 miles away at the former Massachusetts headquarters of Foster-Miller, now a part of British defense contractor Qinetiq. The company did not respond to repeated requests for comment. The contract is expected to be awarded in early 2019. Both Endeavor and Qinetiq have strong track records with the U.S. military, having supplied it with its earlier generation of ground robots such as Endeavor's Packbot and Qinetiq's Talon and Dragon Runner. After hiding the Scorpion behind a shroud at a recent Army conference, Bielat and engineers at Endeavor showed it for the first time publicly to The Associated Press in November. Using a touchscreen controller that taps into the machine's multiple cameras, an engineer navigated it through tunnels, over a playground-like structure and through an icy pool of water, and used its grabber to pick up objects. It's a smaller version of its predecessor, the Packbot, which was first used by U.S. troops in Afghanistan in 2002 and later became one of soldiers' essential tools for safely disabling improvised explosives in Iraq. Bielat said the newer Scorpion and Centaur robots are designed to be easier for the average soldier to use quickly without advanced technical training. "Their primary job is to be a rifle squad member," Bielat said. "They don't have time to mess with the robot. They're going to demand greater levels of autonomy." It will be a while, however, before any of these robots become fully autonomous. The Defense Department is cautious about developing battlefield machines that make their own decisions. That sets the U.S. apart from efforts by China and Russia to design artificially intelligent warfighting arsenals. A November report from the Congressional Research Service said that despite the Pentagon's "insistence" that a human must always be in the loop, the military could soon feel compelled to develop fully autonomous systems if rivals do the same. Or, as with drones, humans will still pull the trigger, but a far-away robot will lob the bombs. Said P.W. Singer, a strategist for the New America Foundation think tank: “China has showed off armed ones. Russia has showed them off. It's coming.” https://www.armytimes.com/news/your-army/2018/12/30/army-looks-for-a-few-good-robots-sparks-industry-battle/

    New defense budget bill foresees US-Israel counter-drone cooperation

    By: Seth J. Frantzman JERUSALEM — For the first time, the National Defense Authorization Act includes a section on U.S.-Israel cooperation in countering unmanned aerial systems, in the fiscal 2019 version. The cooperation will identify “capability gaps” of the U.S. and Israel in countering UAVs and seek out projects to address those gaps to strengthen U.S. and Israeli security. The new cooperation envisions funding for research and development efforts and identifying costs that foresee close cooperation modeled on previous successful programs that Israel and the U.S. have collaborated on, including missile defense and anti-tunneling initiatives. Israel and the U.S. have been at the forefront of air defense cooperation for decades. U.S. Reps. Charlie Crist and Mike Johnson introduced in February a bill titled “United States-Israel Joint Drone Detection Cooperation Act.” Parts of the bill were included in the NDAA passed in both houses of Congress in July. “I am honored to have our bill included in the NDAA and to see it signed into law by President [Donald] Trump. This is an important step not only for our strongest ally in the Middle East but for the United States as well,” Johnson said in July. The president signed the NDAA into law on the afternoon of Aug. 13. The initiative foresees “joint research and development to counter unmanned aerial vehicles [which] will serve the national security interests of the United States and Israel.” Included as Section 1272 of the final NDAA presented to the president on Aug. 3, the cooperation contains five parts, including identification of the capability gaps that exist, identifying cooperative projects that would address the gaps, assessing the costs of the research and development, and assessing the costs of procuring and fielding the capabilities developed. Reports on the cooperation will be submitted to the congressional defense committees, the Senate Foreign Relations Committee and the House Foreign Affairs Committee. The threat of drones has increased in recent years. On Feb. 10 an Iranian-made drone entered Israeli airspace near the northern town of Beit Shean. It had flown from the T4 air base in Syria. Israel identified and tracked the drone from Syria and sent an Apache helicopter to shoot it down. The drone was revealed to be armed with explosives. Former Mossad chief Danny Yatom said in an interview in April that the drone was sophisticated and “an exact replica of the U.S. drone that fell in their territory,” referring to the American RQ-170 Sentinel, which was downed in Iran in 2011. Iran developed two drones based on the Sentinel, one called Shahed 171 and an armed version dubbed Saeqeh, which debuted in 2016. In 2012, Hezbollah used a drone to try to carry out surveillance of the Dimona nuclear reactor in southern Israel. “It's not the first time and it will not be the last,” warned Hezbollah leader Hassan Nasrallah. Conflict Armament Research reported in March 2017 that kamikaze drones using Iranian technology were being used by Houthi rebels in Yemen against Saudi Arabia and the United Arab Emirates. The UAE has sought to bring attention to this threat during the conflict in Yemen, in which a Riyadh-led coalition is fighting the Houthis. Drones were also used by the Islamic State group to attack U.S.-led coalition forces in Syria and Iraq. And Afghan officials reported an Iranian drone entered their airspace in August 2017. In September 2017, Israel used a Patriot missile to down a Hezbollah drone. Israel used Patriotmissiles twice to down Syrian UAVs near the Golan Heights demilitarized zone in July 2018. The U.S. reportedly used an F-15E Eagle to shoot down an Iranian-made Shahed 129 drone in June 2017 in Syria. The drone was heading for the U.S. base at Tanf, which is located in Syria near the Jordanian border. A systematic examination of the emerging drone threat is in the works. The U.S. Defense Department has been allocating resources to counter UAVs, with U.S. Central Command requesting up to $332 million over the next five years for efforts to counter drones. The U.S. Army has been looking for new missiles to defend against a variety of threats, including drones. This will include the Expanded Mission Area Missile and may include other Israel missiles such as the Tamir interceptor for use with a multimission launcher. https://www.defensenews.com/unmanned/2018/08/13/new-defense-budget-bill-foresees-us-israel-counter-drone-cooperation/
