History of Combat Diving

SOF's Aquatic Pioneer. Dr. Christian J. Lambertsen was a pioneer in underwater operations. While a student at the University of Pennsylvania, he developed a closed-circuit underwater rebreather. A true innovation, it allowed the swimmer to remain underwater for longer periods and prevented detectable bubbles from escaping to the surface. In 1942, Lambertsen demonstrated the system to representatives of the wartime Office of Strategic Services (OSS), who recognized its combat potential. In 1944, he was assigned to the OSS Maritime Unit where he instructed swimmers in the use of the Lambertsen Rebreathing Unit (LARU). Read more in "Dr. Christian J. Lambertsen - Aquatic Pioneer", ARSOF History, September 2026.
