An aircraft which has a very low observability visually and to radar, thermal and acoustic detecting devices. The aircraft is designed to have as few edges and surfaces as possible, such as a delta wing type, the edges being straight, or near straight and the vertices rounded. All surfaces are as near flat as possible, within the limits of aerodynamic requirements, and the entire surface of the aircraft is electrically conductive with minimum discontinuity. The propulsion unit is faired into and shielded from radar by the wing. Portions of the aircraft, ...


An aircraft of low observability, comprising: a wing having a nose portion, swept back leading edges extending from the nose portion, and a trailing edge, major portions of the edges being substantially straight in planform; said wing having upper and lower surfaces, major portions of which are substantially flat; the wing having rounded tips blending tangentially into said leading and trailing edges and having a radius of at least one quarter wavelength of the lowest frequency radar expected to be encountered; extended aerodynamic tips of radar transpar...
