SOICAL Cone [NRO]
SOICAL Cone (Space Object Identification Calibration - Cone) was an Air Force surveillance calibration spacecraft launched from Vandenberg AFB aboard a Thorad-SLV2G Agena-D rocket.
SOICAL was also known as S69-4 in the STP program. Two SOICAL satellites were on this launch: one in shape of a cylinder (SOICAL Cylinder), the other in the shape of a cone.
SOICAl Cone was a 55.9 cm diameter right circular cone 66 cm long. It was deployed from the center position of the Agena-D upper stage.
