L3 Cincinnati Electronics is a world-leader in range safety protection.  Applications include missiles, unmanned aerial vehicles, heliostats and decoys.  L3 CE is the provider of the next-generation flight termination receiver.


Our Range Safety Receivers are available in a series of designs for specific launch applications. L3 CE Range Safety Receivers have been used during all major U.S. Space launches - including the Space Shuttle - and on Minuteman and Peacekeeper test flights as well as other earlier missions. The complete product list for this category includes:

CRD-124/207 High-Alphabet Command Receiver/Decoder

Model CRD-124/207 Command Receiver/Decoder was developed specifically to operate on the solid-rocket boosters (SRB) during launch of the Space Shuttle. The unit is designed to replace the now obsolete Model CRD-111/202, and incorporates all the functions performed previously by the distributor units on the SRB. The new CRD-124/207 Command Receiver/Decoder receives radio frequency (RF) commands, discriminates and decodes them, sends and receives hardwired commands for cross-strapping, and implements ordinance initiation output. This CRD unit also provides the command interface for the Range Safety System (RSS), safe and arm (S&A) device, and provides command status and performance data to the measurement system.

CR-128 EFTS Command Receiver for Missiles and Remote Control

Model CR-128 Command Receiver is a compact, cost-effective range safety receiver/flight termination receiver designed specifically for missile and remote control applications. The next-generation receiver is specifically designed for the Enhanced Flight Termination System (EFTS). Lightweight, low-power, small-volume (3.7 in3), and configurable digital processing with embedded COMSEC (3DES) make the receiver ideal for numerous data link applications.
