The fourth KH-7, SV 954, was launched on 1963 Dec 18 by Atlas Agena D from Point Arguello. The Agena 4802 upper stage was not separately tracked, but is believed to have separated after launch. The first use of a 4800 series Agena may indicate an operational variant. The orbit perigee was 30 km lower than targeted. The spacecraft remained in orbit for only 31 hours.
