logistics challenge sparked a movement to break a nearly century-old barrier holding back heavy vertical-lift aircraft. Phillip “Donna” Smith is a program manager in DARPA’s Tactical Technology Office. He oversees several of the agency’s aerial drone programs, including the Lift Challenge, a national public competition that began with one simple metric: improve payload-to-weight ratio in vertical aircraft, which currently lift only as much as they weigh. What began as a hypothesis that these aircraft could lift four times their current weight using more aerodynamic designs, new materials, and better flight controls rapidly became a path to even higher payload efficiency.  Smith shares insights from the 2026 competition and what led to the decision to go for even bigger goals in 2028. Additional Lift Challenge information, competition recaps, and upcoming milestones are available at www.darpa.mil/lift.  Video playlist for DLC

As the landscape of naval warfare changes, traditional defense methods like large convoys and standard object recognition are becoming impractical. New, scalable solutions are needed to help U.S. Navy Sailors identify maritime threats, track potential targets, and safeguard the massive commercial and military logistics vessels that form the backbone of global trade and defense. In this episode, we speak with Christopher Kent, a program manager in DARPA’s Tactical Technology Office. With a background in naval architecture and as the former Deputy Chief Engineer for the Department of the Navy, Kent came to DARPA to solve real-world problems. He shares his work on developing innovative technologies that provide a new layer of security for vessels at sea as well as other parts of the battlefield, including: Pulling Guard: A semi-autonomous, unmanned system towed behind a ship that acts as a dedicated mobile sentry. It can detect and neutralize threats, providing military-grade protection to commercial vessels without the insurance and regulatory burdens of arming the host ship itself. Heimdall: Advanced tracking software, inspired by human vision, that can lock onto and follow potential threats in cluttered and chaotic environments. Originally designed for maritime use, this technology has proven so effective that the U.S. Army is also adopting it for ground-based defense systems.

What new capabilities can we unlock by understanding how to rearrange the building blocks of matter? At some time in our lives, most of us have learned that matter is made of molecules, molecules are made of atoms, and atoms are made of protons, electrons, and neutrons. But what’s less commonly learned is what’s going on inside those atoms and molecules, such as when a bond breaks or internal components are rearranged through a chemical reaction. In this episode, we sit down with Keith Whitener, Ph.D., a program manager in DARPA’s Defense Sciences Office (DSO), who discusses the inner workings of reaction mechanisms and how atoms and molecules behave at the smallest possible levels. In this episode we discuss how key mentors influenced Keith’s career as a physical chemist, how his stent as a Jeopardy champion connects to his DARPA work, and how his DARPA program portfolio tackles some of the military’s largest operational and logistics problems: SeREne: Aims to make explosives safer to handle and tunable on the flyHNO3: Aims to eliminate a supply chain risk by enabling high-efficiency production of nitric acid directly from air and waterExCURSion: Aims to bypass fuel supply line challenges by generating energy at point of needExPEDitions: Aims to create a new chemistry for electrically rechargeable batteries to have both the power and energy density of carbon-based fuel As promised, you can match wits against Keith by reading through a fan-created archive of Jeopardy appearances, including all the questions and answers for the episodes in which he competed. Music in this podcast episode includes an excerpt of “Tuesday (Groove)” composed by Keith Whitener, available on his legacy personal website.

What if we could turn economic complexity into strategic understanding?  In this episode, we sit down with David Rushing Dewhurst, Ph.D., a program manager in DARPA\'s Information Processing Techniques Office, IPTO.

The Service Chiefs Fellows connect their operational insights with potential DARPA breakthroughs. We explore DARPA’s Service Chiefs Fellowship Program (SCFP), a 12-week immersive experience that brings together participants from various backgrounds across the Department of Defense (DOD) and other U.S. agencies. Its dual core purposes are to educate future leaders from military services and other agencies, helping them "infuse some of the DARPA magic into their home base," and to inform DARPA program managers and performers, many of whom lack military or government backgrounds, about the mission and the needs of current warfighters. This blending of ideas fosters new connections and can even lead participants to return to the agency, as exemplified by Rob McHenry, DARPA's current Deputy Director and the agency’s first Service Chiefs Fellow. As part of DARPA’s broader strategy to engage the U.S. military and other U.S. government partners, the SCFP helps ensure vital ideas take root and flourish where they are most needed.

U.S. national security depends on an aging IT infrastructure that supports a vast network of systems spanning the globe. Over the past three decades, traditional security practices—like virus scanning, patching software, and intrusion detection systems—have led to a landscape of vulnerable systems. The Department of Defense is no exception, where legacy IT systems and even the most advanced fighter jets and weapons platforms are susceptible to exploitable weaknesses. But this doesn’t have to continue being our reality. In this episode of Voices from DARPA, we explore the agency’s groundbreaking work on revolutionizing software development. At the forefront of this transformation is the use of formal methods—a powerful, mathematical approach that ensures robust security and guarantees the absence of vulnerabilities in software systems. Join experts from DARPA and its strategic partners as they explore how these cutting-edge tools are reshaping the security landscape and paving the way for a future where vulnerabilities are not just minimized but provably absent—across the U.S. military and beyond.

What characteristics make a person trustworthy? Under what circumstances would a person delegate life or death decisions to artificial intelligence (AI)? Does it matter that AI systems reflect trustworthy humans’ decision-making preferences, morals, and ethics? If so, what characteristics are most important? These are some of the fundamental questions DARPA researchers are exploring for the In the Moment (ITM) program, which aims to support the development of algorithms that are trusted to independently make decisions in difficult domains, particularly in significant trauma events such as battlefield triage. DARPA’s research has identified the need for fundamentally different approaches to advance AI technology to a place where we’re willing to trust it and not be foolish to do so. Continuing themes from our mini-series on ELSI – ethical, legal, and societal implications of new technologies and capabilities – we meet with DARPA’s ITM program manager, Dr. Patrick Shafto, and the ITM performers and ELSI advisors, who break down how they’re tackling the fundamental question of alignment in the context of human decision-makers and autonomous decision-making tools.
