James V. Boone developed an interest in electronics through his family’s business, Boone Radio Service, in Little Rock, Ark., according to his biography on the Engineering and Technology History Wiki.
For four months, Boone did detail design and drafting, analyzed electrical-load and firing-circuit transients, and wrote specifications for the Air Force’s Bullpup air-to-ground missile. He then transferred to Eglin Air Force Base in Florida and worked as an assistant project engineer on the flight-test program for bomb-navigation systems, rapid-scan radar, and inertial-guidance systems for strategic bombers.
After two years, Boone joined the Air Research and Development Command as a captain at the Wright Air Development Center at Wright-Patterson Air Force Base, in Dayton, Ohio. The organization was responsible for airborne electronics equipment. He also went back to school and received a master’s degree in electrical engineering from the Air Force Institute of Technology, which is located on the base.
After the Soviet Union launched the Sputnik satellite into orbit in 1957, Boone spent three years helping to improve the reception of U.S. telemetry intelligence on Soviet surface-to-air, antiballistic, and intercontinental ballistic missile tests. He was promoted to captain and branch chief of the Fort Meade Army base in Maryland.
Boone eventually became chief of the Advanced Techniques Branch’s radio equipment development division, part of in the U.S. National Security Agency’s research and development organization. There he led the design, development, and implementation of low-noise microwave receivers using parametric amplifiers and masers to monitor aspects of the Soviet space program.
In 1963 Boone went to Germany for two years to help establish satellite tracking, radar, and wireless data collection capabilities at the Bad Aibling satellite-tracking station in Bavaria.
Three years after he returned to the United States, Boone was appointed deputy director for research and development at the NSA. He was responsible for research and engineering at the agency’s signals-intelligence and communications-security missions. He oversaw the launch and operation of the first three SIGINT satellites of Program 366, which allowed the U.S. military to intercept radio transmissions from Earth.
Boone left the military in 1981 and joined TRW Space Park, in Redondo Beach, Calif., now part of Northrop Grumman. He started as an apprentice to the manager of the company’s military electronics division. He eventually became its manager.
Boone received a bachelor’s degree in electrical engineering in 1955 from Tulane University, in New Orleans.
