The first of two communications satellites built for the North Atlantic Treaty Organization (NATO) by the Philco-Ford Corporation under a SAMSO contract was launched from Cape Canaveral aboard a NASA Long Tank Thrust Augmented Thor/ Delta booster. Inserted into synchronous orbit on 23 March, the satellite was turned over to the Supreme Headquarters Allied Forces Europe (SHAFE) on 19 May. Spacecraft engaged in practical applications and uses of space technology such as weather or communication (US Cat C).

As of 2007 Mar 9 located at 100.55W drifting at 0.016W degrees per day.

The second NATO military communications satellite (NATO IIB) was launched by NASA aboard a Thrust Augmented Thor/Delta booster. Developed for NATO under SAMSO program management, the spacecraft was first placed in a transfer orbit and then moved into an acceptable synchronous orbit on 4 February. Although numerous difficulties were experienced prior to launch, the satellite achieved its stationary orbit and has performed successfully since then.
