NATICK, Mass. (Oct. 16, 2015) — Don Holman was raised on a farm in Michigan and served 30 years in the Navy, which makes him a perfect fit to help test whether American warships could one day grow their own fresh vegetables.

Inside a repurposed former refrigerated shipping container tucked behind the Combat Feeding Directorate, or CFD, at U.S. Army Natick Soldier Research, Development and Engineering Center, Holman has been growing lettuce since August in a climate-controlled, 40-by-8-foot “hydroponic farm.” What will be a year-long effort has been undertaken for the Navy, which aims to explore the capability of growing produce at sea utilizing hydroponics technology.

“I want to see what can grow and what can’t grow,” said Holman, an engineering technician with the Joint Foodservice and Engineering Team at CFD and a retired command master chief. “We want to experiment with all varieties of vegetables and see how much produce we can produce.

New method uses water, motion to develop delicious military food

NATICK, Mass. (Sept. 17, 2013) –One of life’s greatest necessities, water, is a key ingredient for the new gentle motion retort used by the Combat Feeding Directorate at the U.S. Army Natick Soldier Research, Development and Engineering Center to develop Meal, Ready-to-Eat and Tray Pack products. This simple molecule is heated to 240 degrees Fahrenheit in order to cook and sterilize foods using one of three different thermal processing methods.

After the successful “retort” process items do not require refrigeration because they have achieved commercial sterilization, the removal of certain pathogenic organisms.

The retort vessel installed at the NSRDEC in January 2013 can process 195 eight-ounce MRE pouches or 20 six-pound polymeric Tray Packs at a time using water immersion, saturated steam, water spray or water spray with gentle motion.
