DARPA: Building Trusted Human-Machine Partnerships

A key ingredient in effective teams – whether athletic, business, or military – is trust, which is based in part on mutual understanding of team members' competence to fulfill assigned roles. When it comes to forming effective teams of humans and autonomous systems, humans need timely and accurate insights about their machine partners' skills, experience, and reliability to trust them in dynamic environments. At present, autonomous systems cannot provide real-time feedback when changing conditions such as weather or lighting cause their competency to fluctuate. The machines' lack of awareness of their own competence and their inability to communicate it to their human partners reduces trust and undermines team effectiveness.

To help transform machines from simple tools to trusted partners, DARPA today announced the Competency-Aware Machine Learning (CAML) program. CAML aims to develop machine learning systems that continuously assess their own performance in time-critical, dynamic situations and communicate that information to human team-members in an easily understood format.

“If the machine can say, ‘I do well in these conditions, but I don't have a lot of experience in those conditions,' that will allow a better human-machine teaming,” said Jiangying Zhou, a program manager in DARPA's Defense Sciences Office. “The partner then can make a more informed choice.”

That dynamic would support a force-multiplying effect, since the human would know the capabilities of his or her machine partners at all times and could employ them efficiently and effectively.

In contrast, Zhou noted the challenge with state-of-the-art autonomous systems, which cannot assess or communicate their competence in rapidly changing situations.

“Under what conditions do you let the machine do its job? Under what conditions should you put supervision on it? Which assets, or combination of assets, are best for your task? These are the kinds of questions CAML systems would be able to answer,” she said.

Using a simplified example involving autonomous car technology, Zhou described how valuable CAML technology could be to a rider trying to decide which of two self-driving vehicles would be better suited for driving at night in the rain. The first vehicle might communicate that at night in the rain it knows if it is seeing a person or an inanimate object with 90 percent accuracy, and that it has completed the task more than 1,000 times. The second vehicle might communicate that it can distinguish between a person and an inanimate object at night in the rain with 99 percent accuracy, but has performed the task less than 100 times. Equipped with this information, the rider could make an informed decision about which vehicle to use.

DARPA has scheduled a pre-recorded webcast CAML Proposers Day for potential proposers on February 20, 2019. Details are available at: https://go.usa.gov/xE9aQ.

The CAML program seeks expertise in machine learning, artificial intelligence, pattern recognition, knowledge representation and reasoning, autonomous system modeling, human-machine interface, and cognitive computing. To maximize the pool of innovative proposal concepts, DARPA strongly encourages participation by non-traditional proposers, including small businesses, academic and research institutions, and first-time Government contractors.

DARPA anticipates posting a CAML Broad Agency Announcement solicitation to the Federal Business Opportunities website in mid-February 2019.

Danish radars on French aircraft carrier
Aarhus, March 25, 2020 - The French aircraft carrier Charles de Gaulle, which visits Danish waters this week, is equipped with two radar systems provided by Terma. The SCANTER 6000 radar systems are used for surveillance, search and navigation at sea - and in the air to guide helicopters on landing. In recent years, Terma has provided radar systems to a number of vessels in the French Navy through a collaboration with the French defense company Naval Group, which among others has built Charles de Gaulle. The French carrier has a fixed crew of about 2,000 men and weighs about 40,500 tonnes. It is accompanied by several escort ships and will be accompanied by the Danish frigate Niels Juel of the Iver Huitfeldt class during its visit. Through its long-standing partnership with the Danish Navy, Terma has provided radar systems, self-defense systems and command-control systems to all of the Navy's large naval vessels, including the three frigates, which also make use of the same radar type SCANTER 6000 as Charles de Gaulle. Terma's radar systems are used by many countries around the world on many different types of navy and coastguard vessels due to their ability to see small targets such as fast crafts and jet skis at long range and in all kinds of weather. Terma's radars are therefore also used for coastal and traffic surveillance e.g. at VTS Storebælt. About us The Denmark based high-tech Terma Group develops products and systems for defense and non-defense security applications; including command and control systems, radar systems, self-protection systems for aircraft, space technology, and aerostructures for the aircraft industry.

Should the military treat the electromagnetic spectrum as its own domain?
By: Nathan Strout Military leaders are reluctant to treat the electromagnetic spectrum as a separate domain of warfare as they do with air, land, sea, space and cyber, even as the service increasingly recognize the importance of superiority in this area. At the Association of Old Crows conference Oct. 30, representatives from the Army, Navy and Air Force weighed in on a lingering debate: whether the electromagnetic spectrum should be considered its own domain. In short, while the spectrum can legitimately be described as a physically distinct domain, it does not make sense logistically for the Department of Defense to declare it a separate domain of warfare, they said. “It's something that we've had a lot of discussion about ... In one way, you can argue that the physical nature of the electromagnetic spectrum, the physical nature of it being a domain. However, I understand the implications and those are different challenges for a large organization like the Department of Defense. So I think that there's a little bit of a different discussion when you talk about domain and what that implies for the Department of Defense and each of the departments in a different way,” said Brig. Gen. David Gaedecke, director of electromagnetic spectrum superiority for the Air Force's deputy chief of staff for strategy, integration and requirements. Regardless of whether it's an independent domain, military leaders made clear that leveraging the electromagnetic spectrum is a priority for every department and every platform. “We're going to operate from strategic down to tactical, and EMS ... is going to enable all of our forces to communicate and maneuver effectively, so we'll have a layered approach across all the domains that we operate in,” said Laurence Mixon from the Army's Program Executive Office for Intelligence, Electronic Warfare and Sensors. “EMS is definitely an aspect of the operational environment that every tactician has to be aware of, understand and leverage. And on the acquisition side we have to consider EMS when we are developing every one of our systems. I think since EMS crosses all of the domains that we currently have today that we identify and use in the joint parlance--I don't think the Army is ready to call it a domain." Similarly, while the Navy is working to understand how EMS works best within the maritime domain, Rear Adm. Steve Parode, director of the Navy's Warfare Integration Directorate, N2/N6F, indicated that there was no rush to declare EMS a separate domain. “For the Navy, we're pretty comfortable with the way we are into the maritime domain as our principal operational sphere. We are working through understanding the EMS and the way it relates to physical properties in that domain. We know where we're strong and we know where we're weak. And we understand principally why we're weak. We're making decisions about how to get better,” said Parode. https://www.c4isrnet.com/electronic-warfare/2019/11/06/should-the-military-treat-the-electromagnetic-spectrum-as-its-own-domain/

US Air Force restricts KC-46 from carrying cargo and passengers
By: Valerie Insinna WASHINGTON — In a move that could have major impacts on the already-delayed tanker program, the U.S. Air Force has indefinitely barred the KC-46 from carrying cargo and passengers, Defense News has learned. The decision was made after an incident occurred where the cargo locks on the bottom of the floor of the aircraft became unlocked during a recent flight, creating concerns that airmen could potentially be hurt or even killed by heavy equipment that suddenly bursts free during a flight. “As a result of this discovery, the Air Force has submitted a Category 1 deficiency report and is working with Boeing to identify a solution,” Air Force Mobility Command spokesman Col. Damien Pickart said in a statement. The service uses the term Category 1 to describe serious technical issues that could endanger the aircrew and aircraft or have other major effects. “Until we find a viable solution with Boeing to remedy this problem, we can't jeopardize the safety of our aircrew and this aircraft,” he said. The problem was discovered during a recent overseas operational test and evaluation flight, when KC-46 aircrew noticed that numerous cargo restraint devices had come unlocked over the course of the multiple legs of the trip. “Prior to departing for each of these missions, aircrew fully installed, locked and thoroughly inspected each restraint, and performed routine inspections of the restraints in flight,” Pickart said. “Despite these safety measures, the unlocking of cargo floor restraints occurred during flight, although no cargo or equipment moved and there was no specific risk to the aircraft or crew.” A source with knowledge of the issue told Defense News that if all restraints on a particular pallet had become unlocked, it would be able to roll freely throughout the cabin. If all cargo became unlatched, it could pose a safety risk to aircrew or even unbalance the aircraft — making the plane “difficult, if not impossible” to control. While this problem has only been observed on one KC-46, the Air Force does not have enough information to rule out other aircraft having a similar defect. The problem also poses a danger to the tanker's operational test schedule, Pickart said. The program was set to start initial operational test and evaluation this fall, with pre-IOT&E activities already initiated. “This is a multi-mission aircraft, it's for carrying cargo and passengers, it's for refueling and also the aeromedical evacuation mission,” he said. “If you can't carry cargo pallets and patient litters, a significant amount of your core missions cannot be properly tested.” In a statement, KC-46 manufacturer Boeing acknowledged that it had been notified of the new issue. “The company and the Air Force are cooperatively analyzing the locks to determine a root cause,” Boeing stated. “The safety of KC-46 aircraft and crew is our top priority. Once a cause has been identified, the tanker team will implement any required actions as quickly as possible.” But the problem could be bad news for Boeing's bottom line. The company is locked into a fixed-price contract for where it is responsible for paying for any expenses beyond the initial $4.9 billion award for development of the aircraft. So far, the company has paid more than $3.5 billion of its own money to fund corrections to ongoing technical issues. The latest Cat-1 deficiency brings the total up to four: The tanker's remote vision system or RVS — the camera system that allows KC-46 boom operators to steer the boom into a receiver aircraft without having to look out a window and use visual cues — provides imagery in certain lighting conditions that appears warped or misleading. Boeing has agreed to pay for potentially extensive hardware and software fixes, but the Air Force believes it will be three or four years until the system is fully functional. The Air Force has recorded instances of the boom scraping against the airframe of receiver aircraft. Boeing and the Air Force believe this problem is a symptom of the RVS's acuity problems and will be eliminated once the camera system is fixed. Boeing must redesign the boom to accommodate the A-10, which currently does not generate the thrust necessary to push into the boom for refueling. This problem is a requirements change by the Air Force, which approved Boeing's design in 2016. Last month, Boeing received a $55.5 million contract to begin work on the new boom actuator. While the KC-46 program has clocked several key milestones this year, it has also hit some publicly embarrassing stumbles. After several years of delays, the Air Force finally signed off on the acceptance of the first tanker. However, due to the list of technical problems, Boeing was forced to accept an agreement where the service could withhold up to $28 million per aircraft upon delivery. About $360 million has been withheld so far, Defense One reported in July. The Air Force plans to buy 179 KC-46s over the life of the program, and 52 are currently on contract. So far, Boeing has delivered 18 tankers to McConnell Air Force Base, Kan.; Altus Air Force Base, Okla; and Pease Air National Guard Base, N.H. But deliveries were interrupted earlier this year by the discovery of foreign object debris in multiple planes. The Air Force suspended KC-46 flights at Boeing's production line in Everett, Wash., this February after finding debris. Then it paused all tanker deliveries in March as the service investigated the extent of the problem. The service began accepting tankers again later that month, only for deliveries to stop — and restart — in April due to similar problems. Will Roper, the service's acquisition executive, told reporters at the Paris Air Show this July that the service expects to find foreign object debris in KC-46s moving through the line, and it may be months before planes are reliably clean. “As those airplanes flow forward down the line, we think it's going to take some time for the new quality assurance inspection processes to start early enough so that airplanes will flow that are FOD-free,” he said, according to Defense One. “It's not the way we want to get airplanes into the Air Force, but it's what we're going to have to do in the meantime.” https://www.defensenews.com/breaking-news/2019/09/11/air-force-restricts-kc-46-from-carrying-cargo-and-personnel
