The US Army is seeking partners to develop plant-based and fermentation-derived proteins for combat-zone meals, with fully vegan MRE options slated for a 2027 debut.
The US military issues more than 37 million MREs a year. If even a fraction of that volume shifts to plant-based meals, it would represent one of the largest single channels of institutional demand for alternative protein in the country — millions of meals served annually to troops, shaped by military procurement standards rather than grocery-store trends.
That is the scale behind a new US Army notice seeking industry and academic partners to help develop alternative protein technologies for combat-zone meals. Green Queen reports that the Army Combat Capabilities Development Command Soldier Center is exploring plant-based and fermentation-derived protein technologies for military field feeding.
The notice is not a finished contract award. It is a Sources Sought call, which means the Army is testing what industry and research organizations may be able to provide. But it still matters because it shows how seriously military food planners are now looking at alternative proteins as a logistics and readiness question, not just a consumer food trend.
The work sits alongside a broader shift in military rations. For MRE 47, expected in 2027, Army food scientists have been developing more plant-based items after service members asked for more options. The current 24-item MRE menu includes four vegetarian meals, and those are expected to be replaced with fully plant-based options.
The Army’s framing is unusually direct. The Soldier Center says it is exploring how the alternative protein sector can help meet several objectives, including stronger food supply chain resilience, biomanufacturing of foodstuffs in combat-forward environments, and tailored, high-quality nutrition for the warfighter.
Translation: the Pentagon is interested in protein that can potentially be produced closer to where troops are operating, without relying as heavily on long and fragile supply chains.
The current notice prioritizes plant-based and fermentation-derived proteins while excluding cultivated meat and insect protein from the scope. Any qualifying technology has to clear a high bar on shelf stability, palatability, nutrition, and GRAS (Generally Recognized As Safe) status, with an emphasis on lightweight and nutrient-dense ration solutions that can reduce logistical burdens and the physical load carried by warfighters.
Soldier demand has been moving in this direction for a while, though the numbers need to be read carefully. A 2022 Mercy For Animals survey of 226 active-duty service members found that 81 percent believed the military should provide more plant-based options, while 69 percent said plant-based MREs should be available. More than half said they would choose plant-based MREs over animal-based ones if given the option.
The cultivated meat exclusion is also worth noting. In 2024, livestock industry groups pushed back against Department of Defense-linked funding opportunities involving cultivated meat for military rations. The National Cattlemen’s Beef Association later said the DoD would not move forward with that proposal. That history helps explain why this round is narrower, even as the Army continues to explore alternative proteins more broadly.
The strategic logic the Army is articulating is less about diet politics and more about logistics. Long supply chains are a vulnerability. Shelf-stable, lightweight, plant-based protein that can potentially be produced closer to deployment zones is a procurement problem dressed up as a food problem. That is the calculation driving this notice, more than any preference about what soldiers should eat.
The implications cut in two directions. If suppliers can meet the Army’s standards on shelf life, palatability, nutrition, and field performance, the plant-based sector gains a rare kind of validation: military interest based on cost, durability, resilience, and operational usefulness. That could strengthen the category’s credibility with institutional buyers far beyond the defense world. If suppliers fall short, critics will have a high-profile example to argue that alternative protein is not yet ready for serious field applications. Either way, the move puts plant-based protein in a new frame — not as a lifestyle choice, but as a possible tool for supply chain resilience and combat readiness.
