Did you know that for about 80 years, the United States Navy was in the dairy farm business, and for several decades even operated a hog farm? So in 1913, the Navy bought a large acreage in Gambrills, Maryland, and began raising hogs on the former dairy facility. The Navy seems to have developed a modern dairy operation that milked from 175 to 250 Holstein cows and raised replacement calves as well. In 1980, a farm building inventory listed a total of 62 buildings and other structures on the farm. Finally, in 1998, the Navy’s farm could no longer be justified and the dairy operation was closed down.
