On 13 June 1960 a radar cross section investigation was begun for the Boeing Airplane Company (Wichita, Kansas) under Boeing Airplane Company Purchase Order No. 295353. The program of study is outlined in Boeing document No. D3-3077. Briefly the program consisted of a study of the radar cross section characteristics of three models which were defined in D3-3077 as follows: Model "A" - Model "A" to be a model in the general configuration of an airplane having a wing span of approximately 21 - inches and 2 a fuselage length of 32 inches. Model "B" - Model "B" to have the same dimensions as Model "A" but will differ slightly in configuration. Model "C" - Model "C" will be a geometrical construction resembling two spheroids connected by a long cylinder. In fact "A" was an "airplane" having a cylindrical fuselage and straight wings while "B" had a curved fuselage and curved wings. Figure 1-1 contains photographs of the three models.
