The U-2 project was set in motion by Maj. John Seaberg, an air force reservist recalled to duty as assistant chief of the New Developments Office at Wright-Patterson Air Force Base. Seaberg, who had worked as an aeronautical engineer at Chance Vought, realized the new generation of jet engines being developed in the early 1950s had an inherent high-altitude capability. If matched with extremely efficient wings, the resulting aircraft would have a maximum altitude far above the reach of any interceptor. It would be ideal for reconnaissance.
By March 1953, Seaberg had written a formal design study. It envisioned an aircraft with a maximum altitude of 70,000 feet, a range of 3,000 miles, subsonic speed, up to 700 pounds of reconnaissance equipment, a one-man crew, and the use of existing engines. Two requirements would have a long-term impact on both this and later Black airplanes. Under 'Detectability,' the requirement stated: 'Consideration will be given in the design of the vehicle to minimize the detectability by enemy radar.' Under the category of 'Vulnerability,' it stated: 'It is anticipated that the enemy will have limited means of detection and/or interception of a vehicle of the required performance. The greatest opposition to the operation of this aircraft can be expected to be encountered from guided missiles.'
Major Seaberg went to possible contractors. It was decided to bypass large prime contractors such as Boeing, Convair, North American, Douglas, and Lockheed. The aircraft was highly specialized, and the number produced would be small. A smaller company would give it both a higher priority and a more innovative design. Bell Aircraft and Fairchild were asked to submit designs, while Martin was asked to modify its B-57 Canberra light bomber.
By January 1954, the three proposals were finished. Fairchild's M-195 design featured an intake behind the cockpit and a tail mounted on a short boom. The landing gear was a tail wheel and two main wheels in the wing.
The Bell Model 67 was a large, twin-engine design of a more conventional appearance. The Martin RB-57D proposal had extended outer wings and new engines. All three designs used Pratt and Whitney J57 engines, which were the best then available for such extreme altitudes.
In early May 1954, the evaluation was completed and approval was given to build two of the designs. The Martin RB-57D was to be the interim aircraft, able to provide a limited high-altitude capability in a short time. It would not meet the full requirement, however.[29] To do this, the Bell design was selected. To hide its reconnaissance mission, it was designated the 'X-16.'
The X-16 was a very large, yet delicate-looking aircraft. It was 60.85 feet long, with a wingspan of 114.85 feet, but the cylindrical fuselage was only 4 feet in diameter. It used 'bicycle' landing gear — front and back wheels with two retractable outriggers in the middle of the wings for balance (similar to the B-47). There were three sensor bays — one in the nose, and one in front of and one behind the rear landing gear bay. The cameras could cover an area 50 miles wide and 795 miles long. Weight was the primary concern. The two J57 engines produced only 743 pounds of thrust each at 65,000 feet. Above this, the thrust dropped off sharply. The X-16 weighed 36,200 pounds fully loaded, and there was no margin for added weight or drag.
The X-16 mock-up was finished in mid-1954. It consisted of the fuselage and included the cockpit, camera bays, a stub wing, and landing gear. A separate mock-up of the J57 engine was also built. The mock-ups were housed in a special tent, with access limited to project personnel. By October 1955, the prototype X-16 was 80 percent completed. But it was already too late.[30]
Kelly Johnson also had heard about the request for a special high-altitude aircraft. Although Lockheed had not been asked to submit a proposal, he did so anyway. The CL-282 was an XF-104 fuselage fitted with long-span wings. It was much smaller than the X-16—44 feet long with a 70.67-foot wingspan. The emphasis was on weight savings. The airplane had no landing gear; the CL-282 was to take off from a wheeled dolly, then land on two skids. The cockpit was unpressurized, and there was no ejector seat. The camera bay was behind the cockpit.
Johnson's proposal arrived on Seaberg's desk on May 18, 1954, some two weeks after the go-ahead for the RB-57D and X-16. In June, Seaberg recommended the CL-282 be rejected. The primary reason was its use of the General Electric J73 engine. This was an unproven (and ultimately unsuccessful) design. The XF-104 fuselage could not be easily enlarged to accommodate the preferred J57 engine. The air force agreed with Seaberg's recommendations. But Johnson had already submitted the proposal elsewhere. [31]
The CIA was keeping in close touch with the air force on the emerging special reconnaissance program. The CIA's assessment of the CL-282 was very different from Seaberg's. It was 'considered to be the best.' It had a maximum altitude of 73,000 feet over the target and a speed between 450 and 500 knots. The prototype could be ready in a year, with five planes delivered in two years. The X-16, it was noted, could only reach 69,500 feet and had inferior speed and range.[32]
The
They were slow and capable of only a one-way attack on the United States.
By the early 1950s, this situation started to change. The first operational Soviet A-bombs were being deployed. Test flights of the Soviet turboprop Tu-95 and Mya-4 jet bombers were under way. The Soviets were also working on long-range ballistic missiles. For the first time, a surprise nuclear attack on the United States seemed possible.
On March 27, 1954, President Dwight D. Eisenhower told the Science Advisory Committee of the Office of Defense Mobilization, 'Modern weapons had made it easier for a hostile nation with a closed society to plan an attack in secrecy and thus gain an advantage denied to the nation with an open society.' The United States was vulnerable to both a surprise attack and political blackmail. These fears also drove up military spending, which Eisenhower saw as a danger to the U.S. economy. On July 26, Eisenhower asked Dr. James R. Killian, the president of Massachusetts Institute of Technology, 'to direct a study of the country's technological capabilities to meet some of its current problems.' The group was to look at ways of overcom-ing the lack of strategic intelligence on the Soviet Union.
One member of the panel Dr. Killian assembled was Dr. Edwin H. Land, a noted photo scientist. Dr. Land was named to head Project 3 of the Technological Capabilities Panel, often called the 'Land Panel.' Dr. Land once said that discoveries were made by people who had freed themselves from conventional thinking and had the ability to take a new look at old data. Dr. Land realized that technological advances promised a revolution in photo reconnaissance — thin plastic film bases, lens designs which increased resolution 500 percent, computer custom grinding of lenses, and innovative camera designs that allowed a single camera to provide both high-resolution and horizon-to-horizon coverage. Use of a camera incorporating these advances would save weight, increase performance, and provide the intelligence the United States needed.'
The Land Panel was briefed by Seaberg on the Fairchild M-195, the Bell X-16, the Martin RB-57D, and the Lockheed CL-282. Aware of the growing support for the Lockheed plane, Seaberg showed the panel a graph that demonstrated that all three designs were aerodynamically similar. If the CL-282 was fitted with a J57 engine, it would be competitive. The following day, Johnson underwent intensive questioning about the CL-282. Johnson said he would use a J57 engine. He also promised to have the prototype ready within eight months after the go-ahead. This was an extraordinary schedule — the RB-57D and X-16 projects had been under way for several months yet the RB-57D would not fly until November 1955, while the X-16 would not go aloft until early 1956. Johnson said he could beat them both, although all Lockheed had was a 'paper airplane.'[33]
On November 5, 1954, Dr. Land wrote a memo to CIA Director Allen Dulles. Entitled, 'A Unique Opportunity for Comprehensive Intelligence,'
it stated about the CL-282: 'No proposal or program that we have seen in intelligence planning can so quickly bring so much vital information at so little risk and at so little cost.'
Land noted that, 'We have been forced to imagine what [the Soviet's] program is, and it could well be argued that peace is always in danger when one great power is essentially ignorant of the major economic, military, and political activities… of another great power… We cannot fulfill our responsibility for maintaining the peace if we are
