Tactical Message Distribution Profile
The Tactical Message Distribution Profile provides standards and guidance to support the exchange of selected messages between Tactical Data Link networks and IP based federation of networks.

FMN Spiral 4 Specification



Obligation: MANDATORY, Lifecycle: CURRENT

The "Minimum Link-16 Message Profile", as described in the FMN Spiral 3 Service Interface Profile for RAP Data, defines the minimum set of data elements that are required to be available for operational or technical reasons so that correctly formatted technical message can be generated to establish the RAP in a federated environment. The implementation of the following message types of ATDLP-5.16 is MANDATORY and refers to Appendix A of the standard for the detailed requirement of receive or transmit support, also based on the role of the MNP Precise Participant Location and Identification (PPLI) MessagesJ2.0 Indirect Interface Unit PPLIJ2.2 Air PPLIJ2.3 Surface (Maritime) PPLIJ2.4 Subsurface (Maritime) PPLIJ2.5 Land (Ground) Point PPLIJ2.6 Land (Ground) Track PPLISurveillance MessagesJ3.0 Reference PointJ3.1 Emergency PointJ3.2 Air Track messageJ3.3 Surface (Maritime) TrackJ3.4 Subsurface (Maritime) TrackJ3.5 Land (Ground) Point/TrackJ3.7 Electronic Warfare Product Information For MNPs that are contributing to Shared Situational Awareness production, the following messages should be supported to maximize the ability to share tactical data J7 Information ManagementJ9 Weapons Coordination and ManagementJ10 Weapons Coordination and ManagementJ12 ControlJ13 Platform and System StatusJ15 Threat WarningJ17 Miscellaneous More recent editions of this standard may be implemented for operational use but ATDLP-5.16 is the minimum to guarantee Link 16 tactical message distribution.

Obligation: MANDATORY, Lifecycle: CURRENT

The JREAP Standard enables TDL data to be transmitted over digital media and networks not originally designed for tactical data exchange. JREAP consists of three different protocols A, B and C. For implementation in FMN only JREAP-C 'Encapsulation over Internet Protocol (IP)' which enables TDL data to be transmitted over an IP network must be used. Refer to Appendix E of the standard for an overview of which messages are MANDATORY for implementation. Within JREAP-C, UTC must be supported as the common time reference. If no common time reference is available, round-trip shall be used.


JREAP is designed to support operations using Link 16 over most communication media (JRE media) including forwarding TDL data over satellite communication links (JREAP-A), serial links (JREAP-B), and over IP networks (JREAP-C). Each JRE medium has unique characteristics. For implementation in FMN only JREAP-C Encapsulation over IP is to be used. It supports UDP Unicast, UDP multicast, and TCP.
