# DARPA Launches $73 Million RAPIID Program for Synthetic Blood Military researchers target deployable freeze-dried blood alternatives to prevent battlefield trauma fatalities. - **Source:** [MIT Technology Review](https://www.technologyreview.com) - **Published:** 2026-10-14 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/3bb11e4d-b969-43f8-897c-504b2fa484a4 ## Lethal Logistics Behind Transfusions In February 2007, a dual-rotor casualty evacuation helicopter called Morphine 1-2 was shot down near Karmah, Iraq, killing seven crew members. The daylight flight was an emergency blood run. Hemorrhage causes roughly 90% of preventable combat deaths, making rapid supply distribution an urgent military priority. ## Storage Constraints Limit Treatment Refrigerated whole blood lasts only 35 days, while unencapsulated platelets spoil within a week at room temperature. Frozen plasma and red blood cells spoil quickly once thawed. A combat trauma study indicates injured personnel face a strict 36-minute window to receive transfusions before survival rates drop precipitously. ## Civilian Deficits Mirror Combat Blood logistics severely impair civilian healthcare systems alongside military operations. A 2025 study in Transfusion found that of 1.2 million American trauma patients needing pre-hospital blood, only 1% received it. The American College of Surgeons notes this shortage drives 10,000 preventable domestic deaths every year. ## RAPIID Program Sets Deadlines DARPA program manager Robert Murray is leading RAPIID, a $73 million initiative following the earlier $47.5 million FSHARP project. RAPIID coordinates parallel clinical trials with the FDA to synthesize shelf-stable plasma, platelets, and red blood cells. The agency aims to field dried blood kits by 2029. ## Freeze-Dried Plasma Precedents Plasma makes up 55% of human blood and represents the most viable shelf-stable candidate. Abandoned in the 1960s over hepatitis transmission risks, modernized purification allowed the military to restart production in 2010. Over the past two years, the FDA authorized two freeze-dried plasma products for emergency use. ## Historical Failures Haunt HBOCs Hemoglobin outside cell membranes scavenges nitric oxide, constricting vessels and damaging organs. In the 1990s, trial drug HemAssist caused 24 deaths out of 52 recipients due to vasoconstriction. A 2008 JAMA review revealed hemoglobin-based oxygen carriers increased overall heart attack risk threefold and mortality by 30%. ## Pharmed Cells Face Scale Limits Stem cell-derived red blood cells created through blood pharming failed cost efficiency goals. DARPA launched a program in 2008 using umbilical-cord blood but abandoned it when production costs remained in the tens of thousands per unit. Even if affordable, lab-grown living cells still require cold storage logistics. ## Indo-Pacific Strategic Blood Vulnerability Geopolitical shifts highlighted logistical fragilities across the Pacific. An Okinawa blood facility serving 27,000 Marines sits 200 meters from vital satellite infrastructure, creating a single point of failure across USPACOM's 100-million-square-mile theater. The 2018 National Defense Strategy prompted military planners to eliminate centralized reliance on vulnerable banks. ## ErythroMer Shields Toxic Hemoglobin Biotech firm KaloCyte designed ErythroMer, an artificial red cell encapsulating donor hemoglobin within a specialized lipid nanoparticle. The membrane prevents nitric oxide scavenging while lipid KC-1003 modulates oxygen binding based on blood pH levels. The resulting powder remains shelf-stable at room temperature for up to two years. ## Overcoming Natural Supply Bottlenecks Relying on expiring donor blood restricts manufacturing scale, as KaloCyte currently sources only 1,000 to 2,000 units monthly. To eliminate reliance on human donors, the company licensed a yeast strain to brew synthetic hemoglobin. Field units will use dual-chamber bags containing dry powder and sterile water for reconstitution. ## Engineering Synthetic Platelet Nanoparticles Platelets act like surveillance drones across the circulatory system rather than simple clotting material. At Case Western Reserve University, bioengineers created SynthoPlate using peptide-coated lipid nanoparticles. These surface attachments bind to von Willebrand factor, adhere to structural collagen, and mimic fibrinogen to link artificial platelets together during injury. ## Operational Impact on Frontline Survival Combining freeze-dried plasma, synthetic platelets, and encapsulated hemoglobin could eliminate complex cold chains across remote combat zones. If FDA approvals succeed by 2029, field medics will carry complete freeze-dried transfusion kits in backpacks, drastically reducing global hemorrhagic mortality and hazardous supply flights over contested airspace. ## Sources covering this story - https://www.technologyreview.com/2026/10/14/1145807/us-military-race-to-make-fake-blood/ — --- _Summary written by Brifing from the original reporting.
