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.

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.
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.
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. Dewhurst works at the complex intersection of economics, data science, and national security to develop tools that help America navigate a world where economic competition has become a primary battlefield.
What does it take to solve the world's most urgent national security and economic challenges? At DARPA, it starts with questioning past assumptions. In this episode, we go behind the scenes of a major organizational pivot to hear directly from the office leaders driving the change.
