For the power plant he selected the General Electric 173/GE-3 nonaf terburning turbojet engine with 9,300 pounds of thrust (this was the same engine he had chosen for the F- 104, which had been the basis for the U-2 design). 1 " Many of the CL-282's design features were adapted from gliders. Thus, the wings and tail were detacihable. Instead of a conventional landing gear, Johnson proposed using two skis and a reinforced belly rib for landing- a common saillplane technique-and a jettisonable wheeled dolly for takeoff. Other tea tures included an unpressurized cockpit and a 15-cubic-foot prnyload area that could accommodate 600 pounds of sensors. The CL--282's maximum altitude would be just over 70,000 feet with a 2, 000-mile range. Essentially, Kelly Johnson had designed a jet-propelled gl"dI er. .~• Early in March 1954, Kelly Johnson submitted the CL-282 de sign to Brig. Gen. Bernard A. Schriever's Office of Development Planning. Eugene Kiefer and Bud Wienberg studied the design and recommended it to General Schriever. who then asked Lockheed to Kelly Johnson . sμbmit a specific proposal. In early April, Kelly Johnson _presented a full description of the CL-282 and a proposal for the construction and maintenance of 30 aircraft to a group of senior Pentagon official s that included Schriever·s superior. Lt. Gen. Donald L. Putt, Deputy Chief of Staff for Development, and Trevor N. Gardner, Special Assistant for Research and Development to the Secretary of the Air Force. Afterward Kelly Johnson noted that the civi lian officials were very much interested in his design but the generals were not.16 The CL-282 design was also presented to the commander of the Strategic Air Command (SAC), Gen.
