The 59th Medical Wing and the San Antonio Military Health System (SAMHS) had the distinct privilege of hosting the Defense Advanced Research Projects Agency (DARPA) Biological Technologies Office (BTO) for a strategic offsite at Joint Base San Antonio–Lackland. The event welcomed the whole 39-member BTO delegation, led by Office Director Dr. Michael Koeris and Deputy Director Dr. Robert Saperstein. Their visit represented a historic moment that brought together the Department of Defense’s oldest continuous military medical wing and one of its most forward-leaning research organizations. At its core, the engagement reflected a shared commitment to grounding emerging biotechnology in the operational realities confronted by today’s medics and warfighters. 

A Century of Medical Innovation 

As the Air Force’s oldest and largest medical wing, the 59th Medical Wing carries a legacy that spans more than a century of military medicine. Its 4,600-member enterprise delivers comprehensive care to more than 250,000 beneficiaries across SAMHS, trains thousands of Air Force medics annually, and provides essential support to global operations. Over decades of conflict, humanitarian response, and medical advancement, its mission has remained consistent: to train medics, deliver trusted care, and advance capabilities that preserve life across the spectrum of military operations. 

Within this historical context, the arrival of DARPA’s BTO marked a natural intersection of innovation and operational necessity. The office’s mandate—to explore, develop, and accelerate biotechnology informed by real warfighter needs—aligns directly with the Wing’s priorities in Tactical Combat Casualty Care (TC3), autonomous systems, human–machine teaming, and emerging threat surveillance. This alignment set the stage for a purposeful and future-focused collaboration. 

Translating Concept into Operational Practice 

The two-day offsite was intentionally structured to connect advanced research concepts with the practical requirements of battlefield medicine. BTO program managers engaged in a wargame built around evolving chemical and biological threat scenarios. These simulations were shaped by the friction, uncertainty, and constraints inherent to austere environments. Subject matter experts from the 59th Medical Wing provided real-time feedback, ensuring that proposed solutions reflected operational constraints rather than ideal laboratory conditions. 

The visit also included a Tactical Combat Casualty Care dry run at the Wing’s VAPOR Trails and TORCH training sites. Here, BTO personnel experienced firsthand the sensory overload, time compression, and resource limitations that define contemporary military medical response. The exercise provided a critical perspective on how new technologies must function when seconds matter, information is incomplete, and lives are at stake. 

Advancing the Next Generation of Battlefield Medicine 

The collaboration between the 59th Medical Wing and DARPA’s BTO demonstrated the enduring value of pairing operational insight with technological vision. The Wing contributed its deep experience in frontline medical care, while DARPA brought its tradition of pioneering unconventional solutions to complex challenges. Together, this partnership is positioned to develop capabilities that are not only innovative but also rugged, intuitive, and resilient, designed to save lives in the first minute and the first mile of a conflict. 

This engagement reaffirmed the longstanding connection between the U.S. Air Force and DARPA, linking decades of medical heritage with the promise of next-generation biotechnology. The foundation laid during this visit will shape future advancements in battlefield medical care and strengthen protections for warfighters in the years ahead. The 59th Medical Wing was honored to host this significant gathering and remains committed to supporting the continued evolution of military medical innovation.
