Military messaging - EIDNEX

EID built up unique expertise in the field of military messaging, having developed and supplied various generations of systems for tactical and strategic environments, from ACP 127 compliant solutions to STANAG 4406/ACP123 systems.


EID’s latest generation of strategic and tactical Military Message Handling Systems compliant with STANAG 4406 Ed.2, which is the standard specified and ratified by NATO member countries.

Although MMHS is, at a first glance, comparable to commercial e-mail, significant differences do indeed exist. In fact, defence organizations require a formal secure messaging system that ensures:

  • Interoperability among NATO nations;
  • Confidentiality;
  • Integrity, non-repudiation of origin and assurance of delivery;
  • Appropriate handling mechanisms applied to each message according to its precedence and classification.

The system also provides message transfers to tactical networks integrating naval, airborne and army mobile radio units, in accordance with STANAG 4406, Annex E, and in such a way that substantially higher data throughputs than with the ACP127-based systems are achieved.



    MOST4 SHIPS is an Automatic Message Handling System featuring a comprehensive set of facilities aimed at reducing the overheads of traditional on-board message management tasks. Providing a substantial degree of automation, the system reduces the operator´s workload, thus minimising the likelihood of occurrence of operational and administrative mistakes.

    MOST4 Ships features include:

    • On-site reconfiguration, according to the prevailing operational requirements;
    • Upgradeability, in terms of processing power and number of operator terminals;
    • Standard interface to other systems/networks;
    • Compatibility with a wide range of industry standard hardware platforms, either commercial, ruggedised or mil-spec personal computers/workstations.

    STANAG 4406 compliant solutions can also be integrated in MOST4 Ships, fulfilling ship message requirements in a transition period from ACP 127 to Tactical MMHS.
