In the wake of the Iraq and Afghanistan wars, the mental health crisis among U.S. military veterans remains unrelenting, despite the best efforts of healthcare researchers and providers to confront the scale and scope of the problem. According to a 2018 report from the Department of Veterans Affairs, an average of twenty U.S. veterans commit suicide each day.

DARPA today announced the 10 teams that have qualified for the Championship Event of the Spectrum Collaboration Challenge (SC2) – a three-year contest to unlock the potential of the radio frequency (RF) spectrum using artificial intelligence (AI). The teams will head to Mobile World Congress Los Angeles on October 23, 2019, where their radio designs will go head to head during a live competition. The first, second, and third place winners will walk away with $2 million, $1 million, and $750,000 prizes, respectively.

Over the past three years, DARPA’s Spectrum Collaboration Challenge (SC2) has relied on a custom-built virtual testbed called the Colosseum to host thousands of competitive matches and scrimmages, which will include the final match to determine the winner of the $2 million grand prize. Supporting SC2’s mission to reimagine new spectrum access strategies in which radio networks autonomously collaborate to determine how the RF spectrum should be used moment-to-moment required the development of a research environment capable of emulating communication signals at real-world scope and scale.

The threat of manipulated multi-modal media – which includes audio, images, video, and text – is increasing as automated manipulation technologies become more accessible, and social media continues to provide a ripe environment for viral content sharing. The creators of convincing media manipulations are no longer limited to groups with significant resources and expertise. Today, an individual content creator has access to capabilities that could enable the development of an altered media asset that creates a believable, but falsified, interaction or scene.

Subterranean (SubT) Challenge Systems teams are trekking toward the Urban Circuit after competing in the Tunnel Circuit, the first scored event of DARPA’s high-tech underground contest. Eleven teams from eight countries gathered in Pittsburgh, August 15-22, 2019, to attempt to map, identify, and report artifacts along the passages of two Pittsburgh mines. With them, they brought 20 unmanned aerial vehicles, 64 ground robots, and one autonomous blimp robot named Duckiefloat.

Many of today’s communications, navigation, financial transaction, distributed cloud, and defense applications rely on the precision timing of atomic clocks – or clocks that track time based on the oscillation of atoms with the highest degrees of accuracy. Harnessing the power of atoms for precise timing requires a host of sophisticated and bulky technologies that are costly to develop and consume large amounts of energy. New applications and technologies like 5G networks and GPS alternatives will require precise timekeeping on portable platforms, driving a demand for miniaturized atomic clocks with a high degree of performance.

The military relies on advanced imaging systems for a number of critical capabilities and applications – from Intelligence, Surveillance, and Reconnaissance (ISR) and situational awareness to weapon sights. These powerful systems enable defense users to capture and analyze visual data, providing key insights both on and off the battlefield. Today, nearly all imaging systems rely on detector arrays fabricated using planar processes developed for electronic integrated circuits on flat silicon.

During the second field experiment for DARPA’s OFFensive Swarm-Enabled Tactics (OFFSET) program, teams of autonomous air and ground robots tested tactics on a mission to isolate an urban objective. Similar to the way a firefighting crew establishes a boundary around a burning building, they first identified locations of interest and then created a perimeter around the focal point.

The tremendous ability of the U.S. military to project power entails an equally imposing logistical chain to maintain stocks of food, water, medicines, fuel, and other supplies critical to troops and equipment. That chain gets stretched to extremes when the military is called upon to rapidly deploy anywhere in the world and sustain operations without the benefit of fixed infrastructure.

Department of Defense (DOD) systems and platforms are composed of numerous integrated cyber-physical subsystems, which create an enormous amount of complexity and makes their engineering a daunting task. Today, designing cyber-physical systems (CPS) requires an army of skilled engineers with the right domain expertise, and hundreds of domain-specific tools. The process used to design these systems is largely manual, creating long design cycles that often result in costly redesigns after building and testing the systems. The flaws in the process are numerous – from balancing predictability with cost-efficiency to operating under tight time constraints to integrating disparate pieces from multiple design teams.

This month, DARPA will bring a demonstration version of a secure voting ballot box equipped with hardware defenses in development on the System Security Integrated Through Hardware and Firmware (SSITH) program to the DEF CON 2019 Voting Machine Hacking Village (Voting Village). The SSITH program is developing methodologies and design tools that enable the use of hardware advances to protect systems against software exploitation of hardware vulnerabilities. To evaluate progress on the program, DARPA is incorporating the secure processors researchers are developing into a secure voting ballot box and turning the system loose for public assessment by thousands of hackers and DEF CON community members.

There are times when the highest levels of privacy and security are required to protect a piece of information, but there is still a need to prove the information’s existence and accuracy. For the Department of Defense (DoD), the proof could be the verification of a relevant capability. How can one verify this capability without revealing any sensitive details about it? In the commercial world, this struggle manifests itself across banking transactions, cybersecurity threat disclosure, and beyond.

Over the past few decades, DARPA’s Microsystems Technology Office (MTO) has enabled revolutionary advances in electronics materials, devices, and systems, which have provided the United States with unique defense and economic advantages. To continue its path of successful electronics innovation, DARPA today announced a new MTO effort called the Microsystems Exploration program. The Microsystems Exploration program will constitute a series of short-term investments into high-risk, high-reward research focused on technical domains relevant to MTO.

DARPA’s Squad X Experimentation program aims to demonstrate a warfighting force with artificial intelligence as a true partner. In a recent field test, the program worked with U.S. Marines at the Air Ground Combat Center in Twentynine Palms, California, to track progress on two complementary systems that allow infantry squads to collaborate with AI and autonomous systems to make better decisions in complex, time-critical combat situations.

The Department of Defense (DoD) increasingly relies on software systems to deliver needed functionality, capabilities, and security. However, the rapid pace of software innovation, evolving regulatory requirements, an ever-growing need for stronger system security, and other factors require continual updating and modernization efforts. These produce untenable increases in system complexity and shift the bulk of system costs and developer focus from design and development to maintenance. As this trend continues, the cost and effort required to maintain current systems might constrain DoD’s ability to develop new software-based capabilities.

As some 300,000 cheering race fans packed the stands at this year’s Indianapolis 500, behind the scenes an advanced network of sensors kept constant vigilance, providing security officials real-time awareness of any potential weapon-of-mass-destruction/terror (WMD/WMT) threat. The deployment marked the first time that DARPA’s SIGMA+ network seamlessly integrated radiological and chemical sensors with biological threat sensors from the Department of Homeland Security’s Countering Weapons of Mass Destruction (CWMD) Office.

The DARPA Subterranean (SubT) Challenge opened the Virtual Tunnel Circuit competition July 1 with nine teams vying for a top finish in the event and $500,000 in prizes. Teams that have already qualified can submit their virtual entries at the SubT Virtual Portal during the submission window, which remains open through August 1, 2019. Selecting from a repository of robot models and a variety of sensors, each team can assemble a fantasy sports-style solution to map, navigate, and search the dark, dangerous, and unpredictable underground scenarios.

Breakthroughs in the science of programmable gene expression inspired DARPA to establish the PReemptive Expression of Protective Alleles and Response Elements (PREPARE) program with the goal of delivering powerful new defenses against public health and national security threats. DARPA has now selected five teams to develop a range of new medical interventions that temporarily and reversibly modulate the expression of protective genes to guard against acute threats from influenza and ionizing radiation, which could be encountered naturally, occupationally, or through a national security event.

X-rays and gamma rays have a wide range of applications including scanning suspicious maritime shipping containers for illicit materials, industrial inspection of materials and processes, and medical diagnostic and therapeutic procedures. Current technologies, however, are not ideal. X-rays produce a continuum of energies that limit their inspection and diagnostic performance, and gamma rays can only be produced at specific energies unique to a given radioactive isotope.

For the second year in a row, DARPA is convening the electronics community to discuss the ambitions and achievements of its five-year, upwards of $1.5 billion investment in U.S. microelectronics advancement. Attendees at the second annual Electronics Resurgence Initiative (ERI) Summit – being held July 15-17 in Detroit, Michigan – will hear from commercial and defense leaders as they share their insights on the domestic semiconductor industry and the applications driving next-generation electronics.

The Department of Defense (DoD)’s Joint Logistics Enterprise, which spans both supply chain and logistics operations, provides the means to muster, transport, and sustain military power anywhere in the world at a high level of readiness. To operate successfully in an increasingly contested global security environment, however, the logistics enterprise needs to change how it operates. In particular, the enterprise needs to overcome its reliance on thousands of disparate legacy information systems, which can’t provide the status of millions of military parts, supplies, and pieces of equipment, which are stocked and shipped around the world.

Eleven teams from around the world will attempt to remotely map, identify, and report the greatest number of artifacts along the passages of a Pittsburgh research mine in the Subterranean Challenge Tunnel Circuit. The National Institute for Occupational Safety and Health Mining Program manages the formerly operational mine, which will serve as the arena for the Systems event August 15-22, 2019.

DARPA’s Defense Sciences Office (DSO) will host Discover DSO Day (D3) on June 18, 2019, to facilitate discussion of technical research thrusts outlined in a new office-wide Broad Agency Announcement (BAA) solicitation expected in mid-June.

DARPA has awarded funding to six organizations to support the Next-Generation Nonsurgical Neurotechnology (N³) program, first announced in March 2018. Battelle Memorial Institute, Carnegie Mellon University, Johns Hopkins University Applied Physics Laboratory, Palo Alto Research Center (PARC), Rice University, and Teledyne Scientific are leading multidisciplinary teams to develop high-resolution, bidirectional brain-machine interfaces for use by able-bodied service members. These wearable interfaces could ultimately enable diverse national security applications such as control of active cyber defense systems and swarms of unmanned aerial vehicles, or teaming with computer systems to multitask during complex missions.

Artificial intelligence has defeated chess grandmasters, Go champions, professional poker players, and, now, world-class human experts in the online strategy games Dota 2 and StarCraft II. No AI currently exists, however, that can outduel a human strapped into a fighter jet in a high-speed, high-G dogfight. As modern warfare evolves to incorporate more human-machine teaming, DARPA seeks to automate air-to-air combat, enabling reaction times at machine speeds and freeing pilots to concentrate on the larger air battle.

Could it be that your scent is just a bit too attractive? It is known that mosquitoes are drawn to certain human chemical odors that lead the insects to sources of food. ReVector, a new program from DARPA’s Biological Technologies Office, intends to diminish that attraction — or even actively repel mosquitoes — by engineering the skin microbiome to temporarily alter chemical production. By modulating the interaction of skin-associated microbes with metabolites from the body, ReVector technologies might lower the incidence of mosquito feeding and thus reduce the opportunity for the insects to transmit diseases such as malaria, dengue, and chikungunya that reduce military readiness.

Military systems are increasingly using software to support functionality, new capabilities, and beyond. Before a new piece of software can be deployed within a system however, its functional safety and compliance with certain standards must be verified and ultimately receive certification. As the rapid rate of software usage continues to grow, it is becoming exceedingly difficult to assure that all software considered for military use is coded correctly and then tested, verified, and documented appropriately.

DARPA’s SIGMA program, which began in 2014, has demonstrated a city-scale capability for detecting radiological and nuclear threats that is now being operationally deployed. DARPA is building off this work with the SIGMA+ initiative that is focused on providing city- to region-scale detection capabilities across the full chemical, biological, radiological, nuclear, and explosive threat space.

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 DARPA Launch Challenge aims to fundamentally shift military space capabilities to enable on-demand, flexible, and responsive launch of small payloads. Three competitors successfully completed the qualification phase and will attempt to launch to low-Earth orbit from two different U.S. locations within a matter of weeks. Teams will receive notice of the first launch site a few weeks prior to launch and exact details on the payload and intended orbit just days before launch. DARPA is targeting both launches for early 2020.

Since its official announcement on June 1, 2017, DARPA’s Electronics Resurgence Initiative (ERI) has sought to advance the development of a specialized, secure, and heavily automated electronics industry. ERI – a five-year, upwards of $1.5B investment to enable far-reaching improvements in electronics performance – has fostered collaborations among the commercial electronics sector, defense industrial base, and university researchers. As ERI enters its second year, DARPA seeks to reconvene the electronics community at the second annual ERI Summit in Detroit, Michigan, July 15–17. The Summit will allow electronics innovators to share their vision for the future, review technical progress, and provide input into future research directions.

DARPA is soliciting creative proposals for the fourth swarm sprint in its OFFensive Swarm-Enabled Tactics (OFFSET) program. OFFSET envisions swarms of 250 collaborative autonomous systems providing critical capabilities to ground units in urban areas where challenges such as tall buildings, tight spaces, and limited sight lines constrain essential communications, sensing, maneuverability, and autonomous operations.

For the past decade, cybersecurity threats have moved from high in the software stack to progressively lower levels of the computational hierarchy, working their way towards the underlying hardware. The rise of the Internet of Things (IoT) has driven the creation of a rapidly growing number of accessible devices and a multitude of complex chip designs needed to enable them. With this rapid growth comes increased opportunity for economic and nation-state adversaries alike to shift their attention to chips that enable complex capabilities across commercial and defense applications. The consequences of a hardware cyberattack are significant as a compromise could potentially impact not millions, but billions of devices.

On a brisk February morning in the Yuma, Arizona, desert, a swarm of unmanned aerial vehicles equipped with DARPA’s Collaborative Operations in Denied Environment system, or CODE, successfully carried out mission objectives, even when communications were offline and GPS was unavailable.

The inability of artificial intelligence (AI) to represent and model human partners is the single biggest challenge preventing effective human-machine teaming today. Current AI agents are able to respond to commands and follow through on instructions that are within their training, but are unable to understand intentions, expectations, emotions, and other aspects of social intelligence that are inherent to their human counterparts. This lack of understanding stymies efforts to create safe, efficient, and productive human-machine collaboration.

The current generation of machine learning (ML) systems would not have been possible without significant computing advances made over the past few decades. The development of the graphics-processing unit (GPU) was critical to the advancement of ML as it provided new levels of compute power needed for ML systems to process and train on large data sets. As the field of artificial intelligence looks towards advancing beyond today’s ML capabilities, pushing into the realms of “learning” in real-time, new levels of computing are required.

DARPA aims to apply the power of social networks to research and development via a novel social media platform purpose-built to quicken the pace of U.S. technology development. Polyplexus, which was recently launched as a public platform, is designed to increase access to scientific evidence and accelerate hypothesis development, research proposal generation, and research sponsor engagement. The platform’s real-time interactions and functionality are designed to dramatically shorten the time between the emergence of concepts and the submission of worthy proposals.

Today’s machine learning systems are restricted by their inability to continuously learn or adapt as they encounter new situations; their programs are fixed after training, leaving them unable to react to new, unforeseen circumstances once they are fielded. Adding new information to cover programming deficits overwrites the existing training set. With current technology, this requires taking the system offline and retraining it on a dataset that incorporates the new information. It is a long and arduous process that DARPA’s Lifelong Learning Machines (L2M) program is working to overcome.

DARPA is seeking information on state-of-the-art technologies and methodologies for advanced mapping and surveying in support of the agency’s Subterranean (SubT) Challenge. Georeferenced data – geographic coordinates tied to a map or image – could significantly improve the speed and accuracy of warfighters in time-sensitive active combat operations and disaster-related missions in the subterranean domain. Today, the majority of the underground environments are uncharted or inadequately mapped, including human-made tunnels, underground infrastructure, and natural cave networks.

Small Business Innovation Research and Small Business Technology Transfer (SBIR/STTR) are the principal set-aside programs for small business participation in federal research and development funding, yet the requirements for administering and managing these programs have not changed significantly in decades. To keep pace with discovery in science and technology worldwide, DARPA now intends to release SBIR/STTR opportunities on an out-of-cycle basis, separate from the three pre-determined announcements traditionally issued directly through the Department of Defense (DoD). The change is expected to reduce the overall time from opportunity announcement to contract award.

Universal quantum computers with millions of quantum bits, or qubits – which can represent a one, a zero, or a coherent linear combination of one and zero – would revolutionize information processing for commercial and military applications. Realizing that vision, however, is still decades away. The problem is the performance and reliability of quantum devices depend on the length of time the underlying quantum states can remain coherent. If you wait long enough, interactions with the environment will make the state behave like a conventional classical system, removing any quantum advantage. Often, this coherence time is significantly short, which makes it difficult to perform any meaningful computations.

DARPA has selected five teams of researchers to support PREventing EMerging Pathogenic Threats (PREEMPT), a 3.5-year program first announced in January 2018 to reinforce traditional medical preparedness by containing viral infectious diseases in animal reservoirs and insect vectors before they can threaten humans. Through studies in secure laboratories and simulated natural environments, the PREEMPT researchers will model how viruses might evolve within animal populations, and assess the safety and efficacy of potential interventions.

Goliath grouper, black sea bass, and snapping shrimp, along with bioluminescent plankton and other microorganisms, are set to be the unlikely heroes of DARPA’s Persistent Aquatic Living Sensors (PALS) program. Five teams of researchers are developing new types of sensor systems that detect and record the behaviors of these marine organisms and interpret them to identify, characterize, and report on the presence of manned and unmanned underwater vehicles operating in strategic waters.

Current AI systems excel at tasks defined by rigid rules – such as mastering the board games Go and chess with proficiency surpassing world-class human players. However, AI systems aren’t very good at adapting to constantly changing conditions commonly faced by troops in the real world – from reacting to an adversary’s surprise actions, to fluctuating weather, to operating in unfamiliar terrain. For AI systems to effectively partner with humans across a spectrum of military applications, intelligent machines need to graduate from closed-world problem solving within confined boundaries to open-world challenges characterized by fluid and novel situations.

The testing, evaluation and training of future military systems will increasingly take place in virtual environments due to rising costs and system complexity as well as the limited availability of military ranges. Virtual simulators are already used to augment real-world training for modern fighter aircraft pilots, and they hold significant promise for addressing the rigorous demands of testing and training AI-enabled technologies. Current simulated environments, however, rely on conventional computing that is incapable of generating the computational throughput and speed to accurately replicate real-world interactions, model the scale of physical test ranges or meet the technical requirements of more complex systems.

Blast injuries, burns, and other wounds experienced by warfighters often catastrophically damage their bones, skin, and nerves, resulting in months to years of recovery for the most severe injuries and often returning imperfect results. This long and limited healing process means prolonged pain and hardship for the patient, and a drop in readiness for the military. However, DARPA believes that recent advances in biosensors, actuators, and artificial intelligence could be extended and integrated to dramatically improve tissue regeneration. To achieve this, the new Bioelectronics for Tissue Regeneration (BETR) program asks researchers to develop bioelectronics that closely track the progress of the wound and then stimulate healing processes in real time to optimize tissue repair and regeneration.

Today, machine learning (ML) is coming into its own, ready to serve mankind in a diverse array of applications – from highly efficient manufacturing, medicine and massive information analysis to self-driving transportation, and beyond. However, if misapplied, misused or subverted, ML holds the potential for great harm – this is the double-edged sword of machine learning.

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.
