DIRECT, or Defense IEMATS Replacement Command and Control Terminals, transitions the current command and control system from AUTODIN to Defense Message System (DMS).
The Extremely High Frequency (EHF) project will provide a modernized receive/transmit EHF link from the NCA to the ICBM LCCs.The Miniature Receive Terminal, provides the NCA and nuclear CINCs with survivable C2 link to B-1 and B-52 bombers at the positive control turn around point (PCTAP) for emergency action message (EAM) communications. The Modified Miniature Receive Terminal, or MMRT, will provide the ICBM LCCs and airborne command centers with a common, JCS standard High Data Rate (HIDAR) capability for transmitting/receiving NCA directives. This state-of-the-art upgrade to the Miniature Receive Terminal provides a survivable very low frequency communications receive capability over the MEECN. The MMRT enhances National Command Authority positive control over the strategic forces by meeting the Joint Chiefs of Staff (JCS) MEECN interoperability requirements. A key factor meeting this requirement is the incorporation of the HIDAR message processing algorithm to receive terminals for the E-4B, E-6B, ICBM LCC's and bomber platforms. MMRT capitalizes to the advanced demodulation and signal processing techniques, message processing techniques, and anti-jam capabilities of the MRT to ensure reception of NCA Emergency Action Messages.
