No Water Needed in New Army MRE Heaters

The U.S. Army is working on an improved version of the Flameless Ration Heater that doesn’t need water to heat Meals, Ready-to-Eat.

“Unlike the current ration heater, the Air Activated heater does not require water, a valuable battlefield commodity. This new approach to heating and advanced technology aims to lower cost, weight, and logistics burden of chemical heating technologies,” according to Army officials at Natick Soldier Research, Development and Engineering Center.

The Air Activated Heater contains a peel away layer that, once removed, allows air to penetrate the holes of the outer foil layer. After passing through the felt diffusion layer, the air reacts with the activated carbon, electrolyte, and rate-controlling binder, producing a safe exothermic reaction, Natick officials say.

This new technology will heat the MRE entrée by 100 degrees Fahrenheit in less than ten minutes. Negligible hydrogen off-gassing eliminates operational and transport restrictions associated with the current heater and offers improved safety, according to Natick.

The DoD Combat Feeding Program plans to transition the technical data to Defense Logistics Agency - Troop Support for use with the MRE.
