The Ballistic Missile Defense Organization (BMDO) selected the Joint Tactical Information Distribution System (JTIDS) and the Tactical Digital Information Link J (TADIL J), also known as Link 16, as the primary terrestrial data link in support of Theater Missile Defense (TMD). Subsequent to that decision, BMDO and the Services developed a new set of TADIL J messages to support TMD communication requirements via JTIDS.
To verify the feasibility of the newly defined TMD messages, their transmit and receive protocols, and the reporting responsibility (R2) rules, BMDO sponsored a TMD Message Set Validation modeling and simulation (M&S) task to be carried out by the Modeling, Analysis, and Simulation Center (MASC) at ESC.
This study showed that although there was technically enough capacity to support the required TMD communication requirements concurrently with Theater Air Defense (TAD), load mitigation strategies should be considered to improve performance. The recommended load mitigation strategies included Time-slot Reallocation (TSR) (dynamic capacity sharing between JTIDS hosts) and range extension beyond line of sight without the use of inter-zone relays. The TADIL-J Range Extension (JRE) addresses this last strategy.
