Minuteman ERCS |
 | | However, the type designation (LEM = silo-launched special electronics missile), the time frame of the allocation (late 1965/early 1966), and the lack of an X or Z prefix in the designation (thereby indicating an operational missile) point towards this possibility. |
| | The ERCS UHF transmitters carried prerecorded force execution messages that were transmitted to all units within line of sight of a rocket's apogee. |
| | The Minuteman ERCS became operational in October 1967, and remained in use until 1991, when modern reliable satellite communications systems had made the ERCS unnecessary. |
