In 1939, the Army sent Major George C. Kenney to Puerto Rico to conduct a preliminary survey of possible air base sites on Puerto Rico. He examined a total of 42 sites and declared that Punta Borinquen the best site for a major air base. Planted sugar cane farms covered some 3796 acres that the government purchased for military use in the first week of September 1939 at a cost of $1,215,000. Later that year, Major Karl S. Axtater assumed command of what was to become Borinquen Army Air Field.
