The U.S. Army agreement announced May 5, 2026, funds a 42-month development effort with a potential value of up to $9 million. The system is not a finished product, and the company’s proposed output figures are targets—not verified field results.
What Biosphere’s Army ration project involves
Biosphere announced an Other Transaction Authority agreement made through the Office of the Undersecretary of War Manufacturing Science and Technology Program via the U.S. Army Combat Capabilities Development Command Soldier Center (DEVCOM SC). The project is intended to develop and demonstrate a portable biomanufacturing system for producing food near where military units need it. Biosphere’s May 5, 2026 announcement describes the agreement as having a maximum potential value of $9 million and a 42-month development period.

The schedule is planned to progress from selecting a process and designing the system to pilot-scale demonstrations and a full-scale prototype intended for continuous operation. Biosphere says work will take place at its California facilities, with final product samples delivered to the Army Combat Feeding Division for evaluation. Those are project plans; they do not establish that the system has completed Army evaluation or is operating in the field.
How the proposed UV bioreactor would work
Biosphere describes a system that combines its UV-sterilized bioreactor technology with air, water and energy to produce protein ration ingredients. The design also calls for UV sterilization protocols, recycling of water and growth media, and downstream processing to turn the resulting material into lightweight, nutrient-dense, ready-to-eat food.
#1 Best Overall
- Long Service Life with No Bulb Replacement Needed: Engineered for whole house water treatment, the UVF20 water filter uses a long-life UV module rated for up to 8,000 hours. With about 2-hour daily working schedule, the LED whole house UV water filter can last up to 11 years without needing a bulb replacement
- Built-in Automatic Flow Sensor: Unlike traditional UV systems that remain on continuously, the UVF20 whole house water filter system automatically activates only when water flows through the chamber. This smart feature supports efficient UV exposure while helping extend system lifespan and reduce energy use
- Up to 12 GPM Flow Rate: The UVF20 is designed specifically for home water purification systems and features a 3/4-inch MNPT connector. It supports flow rates up to 12 GPM, making it ideal for whole house water purification systems
- Mercury-Free Whole House Ultraviolet Water Filter Design: The UVF20 utilizes a mercury-free LED UV module that produces no ozone or odor, offering a cleaner and more environmentally friendly solution. Its chemical-free operation makes it compatible with a wide range of residential filtration setups, including well water and municipal water systems
- Instant Startup and Stable Performance: The fast-response whole house ultraviolet water purifier filter provides instant UV exposure with no warm-up time, ensuring smooth operation whenever water is used throughout the home’s filtration system
“From air” does not mean the machine makes food from air alone. The concept depends on a bioreactor and other inputs, including water and energy, as well as processing stages that would turn the output into food. The public project description does not provide completed performance data showing how much of each input the system would need, how much food it can produce, or its full operating and transport burden.
What capacity has Biosphere announced?
Biosphere’s stated target is to provide 2,800 calories per person per day for up to 18 warfighters, with plans to scale the system to support 250 personnel. These are company-announced goals, not demonstrated daily production or confirmed servings. The announcement does not establish that the larger scale has been achieved.

Auto is recommended to protect the UV lamp. The sensor will only kick on when the flow rate reaches 0.66 gallon/minute (2.5 L/m)
- Easy Installation and Simple Maintenance: Mounting clips included for easy DIY installation. Annual replacement of the UV lamp and regular cleaning of the quartz sleeve(every 6-12 months) recommended to ensure optimal performance
- Chemical-free and Reliable Water Treatment: A green alternative to chlorine treatment. Free of chemical byproducts. Low power consumption. Build your trust in water for your entire household by removing risks unable to be addressed by your municipal treatment plant or those born with well water or other natural water sources
- UV Light Technology: Proven quick and reliable method of water treatment for point-of-entry systems, protecting your whole house against water concerns in various water sources including municipal and well water
A separate Army SBIR/STTR program topic describes benchmarks for a broader autonomous, forward-deployed biomanufacturing effort. It calls for a ration providing 3,600 kcal in no more than 900 g, nutrition standards within ±10%, and a sensory score above 6 on a 9-point scale. These are Army program criteria—not results reported for Biosphere’s system. The topic describes modular components and food production using resources including air, microbes, water and energy.

Why the Army is exploring food production near deployed units
The Army program frames point-of-need production as one way to reduce the logistical burden of supplying food and water in contested or denied environments. Producing some food close to a unit could reduce dependence on deliveries in particular conditions, but the proposal does not mean supply chains would disappear. A usable system would still need its inputs, equipment, power, maintenance and food-processing capability at the point of use.

Biosphere co-founder and CEO Brian Heligman said the agreement was “a significant milestone in our mission to advance rapidly deployable biomanufacturing systems.” He also described the company’s aim as producing nutritious, shelf-stable food using its UV-sterilized bioreactor technology. These statements express the company’s goals; they are not independent findings about food safety, shelf life or operational readiness.
Nicole Favreau Farhadi, Technical Lead at the U.S. Army DEVCOM Soldier Center, said the effort reflects a focus on “advancing resilient, forward-deployed capabilities that reduce logistical burden and enhance operational flexibility.” Her comment describes the military rationale for the project, not an endorsement of a completed system.

How this differs from another military ration technology
Biosphere’s proposal is not the only technology pathway explored for military food. In 2023, EnWave reported that it had signed a royalty-bearing commercial license with Bridgford Foods for certain military ration products using Radiant Energy Vacuum (REV) dehydration technology; Bridgford also purchased a 120 kW REV machine. EnWave said a manufacturing technology grant would guarantee the U.S. Department of Defense certain manufacturing capacity at Bridgford’s facility for close-combat field rations. This is a dehydration and ration-processing project, not the proposed Biosphere bioreactor system. EnWave’s 2023 announcement reports the company’s account of the arrangement.

An earlier 2021 EnWave announcement described Bridgford’s Army cooperative research and development agreement and an evaluation and license option involving REV-dried baked goods and meat products. That is historical context, not evidence that Biosphere’s approach has been tested or adopted. EnWave’s 2021 announcement covers that earlier effort.

What remains to be established
The project announcement sets out plans and targets, but does not report completed independent performance testing of Biosphere’s system. Key questions for evaluation include:
- Inputs and energy: how much air, water, media and power are required to produce a given amount of food, and how well recycling works in operating conditions.
- Useful output: whether the system can meet its announced daily calorie targets continuously, and how much space, equipment and processing the full system requires.
- Food quality: whether final products meet applicable nutrition requirements and are safe, palatable and shelf-stable. The planned Army sample evaluation is not yet a reported result.
- Field practicality: how the system performs under deployment conditions, including its maintenance needs, reliability, cost and effect on logistics compared with delivering conventional rations.
Until those questions are answered through demonstrations and evaluation, Biosphere’s Army ration project should be understood as a development program with intended capabilities—not a proven way for soldiers to make meals in the field.
