Technological Innovations in the Early Years of the United States Air Force: 1960-1970

70 Anniversary Technology Poster #1 60-70

Technology Panels/Reviews

No one did more to harness science to air power objectives than Gen. Bernard A. Schriever. As Commander of Air Research and Development Command and its successor, Air Force Systems Command, Schriever had demonstrated great capacity during the 1950s in bringing the American ICBM force to fruition. Then, directed in March 1963 by Secretary of the Air Force Eugene M. Zuckert, he undertook a major review of technologies applicable to USAF needs through the mid-1970s. Called Project Forecast, it enlisted almost 500 participants, balancing blue-suiters who understood the requirements of war with some of the most eminent civilian scientists and engineers from the universities, manufacturers, institutes, and government. In fact, Schriever drew his team from an unprecedented variety of sources - from the USAF and sixty-three other federal agencies, from twenty-six institutions of higher learning, from seventy corporations, and from ten nonprofit organizations. The selection of Schriever and his project manager, Maj. Gen. Charles Terhune, in itself suggests a maturing of the forecasting process. Both men not only understood the scientific world, but represented a growing number of engineers in uniform able to grasp the technical and military aspects of weapons development. As a result, Schriever and Terhune structured Project Forecast so that all ideas produced by the technical panels were assessed in relation to factors of cost and military requirements. In addition, evaluations of the predominant threats to American security and broad foreign policy objectives further narrowed the field of candidate technologies. (Source: Dr. Michael H. Gorn, Technological Forecasting and the Air Force,” in Technology and the Air Force.)

Finally, the capability panels translated the concepts which survived this screening process into actual weapons systems. Far more structured than Toward New Horizons, Project Forecast, nonetheless, incorporated truly independent scientific advice and invited the widest possible participation. Also, like Toward New Horizons, it strove for comprehensiveness, producing twenty-five volumes which related new air power technologies to the world in which the Air Force found itself. Project Forecast enjoyed widespread influence throughout the USAF and many of its recommendations, such as huge intercontinental transports and lightweight composites for aircraft and engine design, were fulfilled.

The Fly-by-Wire Flight Control System Conference, 1968

On Monday and Tuesday, December 16-17,1968 [the 65th anniversary of powered flight in an unstable airplane: the Wright Flyer], the Flight Dynamics Laboratory hosted a meeting of 141 people engaged in fly-by-wire research or vitally interested in its future. The conference was a showcase for the year-old B 4 7 test program and the laboratory prototypes built by Sperry Flight Systems Division and Douglas Aircraft Company. It also gave attendees an opportunity to speculate about the nature of fly-by-wire systems in future aircraft.

The conference papers largely reported on work in progress. The hidden agenda was to create a demand for fly-by-wire so great that further research would be sponsored by the Flight Dynamics Laboratory and its industrial partners. The early results, though promising, still did not fully convince the money controllers in Washington. If the Laboratory personnel and contractors could sell the industry attendees on the idea, then pressure would be applied to the government for further support. As Col. Charles A. Scolatti, Chief of the Flight Control Division, said in the conclusion to his welcoming remarks, “I hope that this conference will provide you with reinforcement on the potential, soundness, and maturity of fly-by-wire flight control systems and open the doors which will permit you to consider fly-by-wire for flight control system tradeoff studies for our future aircraft and aerospace vehicle." In short, the people at Wright-Patterson were sold, and now it was time to sell the others. (Source: Dr. James E. Tomayko, “Blind Faith: The United States Air Force and the Development of Fly-By-Wire Technology,” in Technology and the Air Force.)

Missiles, Missile Warning, Missile Defense, Tactical Missiles

With the advent of the Kennedy administration, the ICBM program was reevaluated once more. Meanwhile, the so-called missile gap faded as interest shifted from the numbers of missiles available to their reliability and flexibility. The Thor IRBM became operational in the United Kingdom between June 1959 and April 1960; Atlas D and E models went on alert between August 1960 and November 1961; Titan I and Atlas F became operational during April to December 1962; and Jupiters were installed in Italy in 1961 and in Turkey in 1962. In all, thirteen Atlas and six Titan I squadrons became operational. Even as these missiles were put in place, important decisions were made with respect to their successors - the solid-fueled missiles. (Source: Jacob Neufeld, “Ace in the Hole: The Air Force Ballistic Missiles Program,” in Technology and the Air Force.)

In March 1961, Defense Secretary Robert S. McNamara returned from a visit to BMD convinced of the necessity for building a solid-fueled ICBM, now called the Minuteman. The development of the Minuteman was so rapid and so successful that it accelerated by several years the phase-out of the first generation, liquid-fueled ICBMs. By December 1964, Atlas Ds came off alert, and by June 1965, Atlas E and F and Titan I were retired. The first ten Minuteman I missiles came on alert in time for the Cuban Missile crisis in October 1962. Eventually a force of 1,000 Minuteman and 54 Titan I1 ICBMs were fielded. (Source: Neufeld)

February 1, 1961: The Minuteman intercontinental ballistic missile was launched for the first time at Cape Canaveral, Florida, in a major test. Under full guidance, it traveled 4,600 miles to its target area. The solid-fueled Minuteman could be stored more easily and fired more quickly than the liquid-fueled Atlas and Titan intercontinental ballistic missiles. (Source: Dr. Daniel L. Haulman, One Hundred Ten Years of Flight: USAF Chronology of Significant Air and Space Events, 1903-2012, with updates by Drs. Priscilla D. Jones and Robert D. Oliver)

February 1, 1961: The ballistic missile early warning system site at Thule, Greenland, became operational. Subsequently, other sites became operational at Clear, Alaska, and Fylingdales in the United Kingdom. Operated by the North American Air Defense Command, the system could provide the United States warning of an impending Soviet missile attack in time to respond.

June 1, 1961: At Kincheloe Air Force Base, Michigan, the first Bomarc-B pilotless interceptor site was declared operational. The Bomarc was a long-range, antiaircraft surface-to-air missile (SAM), the U.S. Air Force’s only one employed. (Source: Haulman)

August 8, 1961: The Air Force launched an Atlas F missile from Cape Canaveral, Florida, for the first time. The Atlas F, designed for long-term storage of liquid fuels and for shortened countdown, was the only Atlas model destined for emplacement in hardened, underground silos. (Source: Haulman)

April 18, 1962: At Lowry Air Force Base, Colorado, Strategic Air Command declared operational the Air Force’s first Titan I unit—the 724th Strategic Missile Squadron. Its nine missiles were the first to be placed in hardened underground silos. (Source: Haulman)

June 8, 1963: The 570th Strategic Missile Squadron, the first Titan II unit, was activated at Davis-Monthan Air Force Base, Arizona. By April 21, 1964, the number of ICBMs equaled the number of bombers on SAC ground alert for the first time. Subsequently, the number of missiles exceeded the number of bombers in the nuclear-deterrent force. (Source: Haulman)

April 20, 1965: Strategic Air Command shipped its last Atlas missile to storage facilities to be used as a launch vehicle in various research and development programs, thus completing the phaseout of the first generation of intercontinental ballistic missiles, all of which were liquid-fueled.

June 30, 1965: At Francis E. Warren Air Force Base, Wyoming, the last of 800 Minuteman I missiles became operational when Strategic Air Command accepted the fifth Minuteman wing from Air Force Systems Command. (Source: Haulman)

October 31, 1965: Strategic Air Command accepted its first 10 Minuteman II missiles, assigning them to the 447th Strategic Missile Squadron at Grand Forks Air Force Base, North Dakota. The Minuteman II was larger and more advanced than the Minuteman I, but it could be fired from the same silos. (Source: Haulman)

February 3, 1968: At the Arnold Engineering Development Center at Tullahoma, Tennessee, a laser beam was used for the first time as a light source for photographing aircraft and missile models at high velocity. (Source: Haulman)

December 18, 1969: Air Force Missile Development Center crews completed the first guided launch of the Maverick—an air-to-surface television-guided missile capable of attacking moving targets at short range. Designated the AGM–65, the missile would eventually be carried by a variety of bomber, fighter, and attack aircraft. (Source: Haulman)

June 19, 1970: The first Minuteman III missile unit became operational at Minot Air Force Base, North Dakota. The Minuteman III could launch multiple, independently targetable warheads. (Source: Haulman)

The USAF continued its quest of cruise missiles with a bit more success in the 1950s and 1960s. It briefly deployed the intercontinental range Northrop Snark in the period 1959-61. It was guided by a one-ton inertial system updated by stellar navigation. But, as with its predecessors, it was expensive, technically flawed, and in the end, unsuccessful. There were numerous aerodynamic problems, and test failures were so frequent that some wit dubbed the waters off of the test site at Cape Canaveral as “Snark-infested waters.” (One missile, however, went too far. It was last seen by the USAF after its launch in 1956; in 1982 a Brazilian farmer in the Amazon basin found it!) Its designated follow-on missile was no better, as the North American Navaho is probably best remembered for the rhyme, “Never go, Navaho.” The USAF did best with the Martin Matador/Mace missile that was operational between 1955 until 1969 in both Europe and East Asia. It was about the size of a fighter and used a number of different guidance systems: radio control (Shanicle), radar map comparison method (ATRAN), and inertial. But like its big brother the Snark, the Matador/Mace’s record was hindered by troublesome engines, guidance, as well as low reliability and accuracy. The Navy had about the same luck (or lack of luck) with its Chance Vought Regulus, a missile that was very much like the Matador in appearance and performance. It did give the Navy a nuclear punch and was liked by some naval officers. (Source: Dr. Kenneth P. Werrell, “The USAF and the Cruise Missile: Opportunity or Threat?” in Technology and the Air Force.)

Precision Guided Munitions

F–4sF–4s with guided bombs brought down the Thanh Hoa bridge.In 1967, an Eglin AFB test unit was in Vietnam with laser-guided bombs, ready to use them in combat, and they were so tested. The reason that they did not get the publicity is that just about the time the USAF started dropping them, President Johnson called a bombing halt. Bombing in the jungles of South Vietnam did not generate the kind of media attention that PGMs later got from Desert Storm. The Eglin unit employed the test items extensively in South Vietnam in 1968 while the bombing halt was operative up north, and the results were highly encouraging. (Source: Dr. David R. Mets, “Stretching the Rubber Band: Smart Weapons for Air-to-Ground Attack,” in Technology and the Air Force.)
