John William Hepfer (9 February 1924 – 25 April 1997) was a leading missile development engineer who played an important role in the development of the Minuteman and Peacekeeper missiles. During World War II he flew 44 combat missions in the Southwest Pacific Area as a navigator of Consolidated B-24 Liberator bombers. He left the Army after the war but was recalled to active duty during the Korean War. From 1962 to 1965 he worked on the development of aircraft systems at the Air Research and Development Command (ARDC). After working on the design of the McNamara Line at the Defense Communications Agency during the Vietnam War, he was transferred to the Space and Missile Systems Organization (SAMSO) in June 1967, where he worked in the Systems Project Office for the Minuteman missile as the chief of guidance and control, and then as the deputy chief of engineering for systems. After a period in command of the Rome Air Development Center, he returned to SAMSO in 1974, and was in change of the guidance and navigation of the Peacekeeper missile.

ARDC was merged with the Air Materiel Command In April 1961 to become the Air Force Systems Command (AFSC), and all research and development activities were consolidated under it. From October 1962 to mid-1965, Hepfer was the program manager for bombing, fire control and navigation systems in the AFSC's Research and Technology Division at Bolling Air Force Base in Washington, DC.

Hepfer was assigned to the Institute for Defense Analysis in Arlington, Virginia in August 1965, and he earned a Master of Arts degree in quantitative analysis at the University of Maryland in 1966. From 1966 to mid-1967, he was part of the Defense Communications Planning Group, a joint task force under the Defense Communications Agency charged with building the McNamara Line, a barrier of electronic sensors stretching across the Demilitarized Zone in the Republic of Vietnam during the Vietnam War.

In June 1967 Hepfer went to the Space and Missile Systems Organization (SAMSO), where he worked in the Systems Project Office for the Minuteman missile at Norton Air Force Base in California as the chief of guidance and control, and then as the deputy chief of engineering for systems. He graduated from the Harvard Business School's program for management development. He attended the Air War College at Maxwell Air Force Base in Alabama from August 1970 to June 1971. He then served as the assistant deputy chief of staff for systems at AFSC Headquarters until September 1973, when he assumed command of the Rome Air Development Center at Griffiss Air Force Base in New York.
