 The wings had four hard points on which to mount the J60 engines and air particulate sampling pods, a gaseous sampling system was housed in the fuselage, and a KA-56 downward-looking panoramic camera mounted in the nose.Two aircraft were additionally modified to carry the Bulova 707-1000 long range camera, which had a 240-inch (608mm) focal length that resulted in its reference designation of "Big Item".These high-altitude side-looking cameras, secured by a roll-stabilized mount, could take oblique shots at 5 to 15 degrees below the horizon up to range from the aircraft and provide 30-inch (76 cm) high resolution images.
