Lockheed continued to work on developing a design that would be less vulnerable to detection, and Convair received a new C[A contract to design an air-breathing twin-engine aircraft that would meet the general specifications being d 11 followed by Lockhee . Following recommendations by the Land committee, both Lockheed and Convair incorporated the Pratt & Whitney 158 power plant into their designs. This engine had originally been developed for the Navy's large, jet-powered flying boat, the Glenn L. Martin Company's P6M Seamaster, and was the most powerful engine available. [n 1958 the Navy had canceled the Seamaster program, which had left Pratt & Whitney without a buyer for the powerful 158 • I~ engine. Although the Land committee had not yet found an acceptable design, it informed President Eisenhower on 20 July 1959 that the search was making good progress. Concerned about the U-2's vulner ability to detection and possible interception and aware that the photosatellite project was encountering significant problems, the President gave his final approval to the high-speed reconnaissance aircraft project. 13 THE SELECTION OF THE LOCKHEED DESIGN By the late summer of 1959, both Convair and Lockheed had com pleted new designs for a follow-on to the U-2. Convair's entry, known as the KINGFISH, used much of the technology developed for the F-102, F-106, and B-58, including stainless steel honeycomb skin, planiform wing design, and a crew capsule escape system, which eliminated the need for the pilot to wear a pressurized suit. The KfNGFISH had two side-by-side 158 engines inside the fuselage, which significantly reduced the radar cross section. Two additional " OSA History, chap. 20, p. I 5 (TS Codeword).
