FAS Project on Intelligence Reform

Joint Tactical Terminal (JTT)
Common Integrated Broadcast Service Modules (CIBS-M)

The Joint Tactical Terminals (JTT) and the Commander's Tactical Terminal (CTT) is a family of special application UHF tactical intelligence terminals which provide the capability to disseminate time sensitive Command, Control, Communications, Computer, and Intelligence (C41), and battlefield targeting information to tactical commanders-and intelligence nodes. This information is provided in near-real-time and allows selected collection managers at all echelons a full-duplex capability to dynamically adjust pre-planned tasking. The terminals supply the critical data link to battle managers, intelligence centers, air defense, fire support and aviation nodes across all services. The JTT and CTT are integrated into other weapon system and are transported with the host system/platform. The equipment will be mounted in fix and rotary winged aircrafts, surface ships, and fixed or mobile ground platforms and vehicles.

The terminals allow Army, Air Force, Navy and Marine Corps users to exploit Integrated Broadcast Service (IBS) networks: Tactical Reconnaissance Intelligence eXchange Service (TRIXS), Tactical Information Broadcast Service (TIBS), Tactical Related Applications (TRAP), and Tactical Data Information eXchange System-B (TADIXS-B). In addition to receiving intelligence data, JTT and CTT transmit TRIXS or TIBS data. The CTT and other IBS terminals are migrating to a single JTT family.

The Joint Tactical Terminal Common Integrated Broadcast Service Modules (JTT/CIBS-M) provide the joint warfighter with access to the intelligence and targeting information on the current intelligence broadcast and will be upgraded to operate on the Integrated Broadcast Service (IBS) when IBS is deployed. The CIBS-M will be used to upgrade MATT and CTT to operate on IBS and to provide IBS functions to other C3I systems.

JTT/CIBS-M consists of a family of tactical terminals and modules for multiple path ultra high frequency (UHF) data communications. The terminals use standard communications equipment to improve supportability during combat operations. The modular approach allows integration into existing systems (e.g., aircraft, ships, submarines, armored vehicles, etc.) and various configurations. JTT/CIBS-M provides producers and users access to the Integrated Broadcast Service (IBS) and other C4I (command, control, communications, computers, and intelligence) communications to operate at varying security levels. JTT/CIBS-M will support advanced encryption techniques.

The JTT/CIBS-M consists of a family of JTT (Terminals) and CIBS-M (Modules). The JTT is available in two models; the JTT-T/R provides one full duplex channel and seven receive channels, the JTT-R provides eight receive channels, additional JTT configurations will be provided as needed. The JTT/CIBS-M provide the joint warfighter with access to the intelligence and targeting information on the current intelligence broadcast and will be upgraded to operate on the Integrated Broadcast Service (IBS) when IBS is deployed. The CIBS-M will be used to upgrade MATT and CTT to operate on IBS and to provide IBS functions to other C3I systems. The JTT/CIBS-M is JTA compliant and is open-architecture, software reprogrammable to facilitate the evolution to IBS, tailored configurations and addition of functions.

There are two initial JTT terminal configurations, JTT-Transmit/Receive (JTT-T/R) and JTT-Receive Only (JTT-R).

The baseline JTT is not a stand-alone system, but consists of two line replaceable units (LRU) (the Receiver Exciter (RE) and the Power Amplifier (PA)) provided by the Program Manager as Government furnished equipment (GFE) and which must be integrated into a C3I host provided by the user. The user is required to provide all antennas, pre-amplifiers, cables, TDP/workstation and other associated equipment. The JTT baseline (JTT T/R) consists of both an RE and PA, and provides the ability to receive on up to eight channels and transmit on one channel simultaneously. Additional PAs could be added (max of 4) to provide additional channels up to the maximum of 12 receive and 4 transmit. The JTT Receive Only Terminal (JTT R) is capable of receiving eight channels simultaneously and contains the RE only. Additional configurations and being considered to include a stand alone suitcase-size terminal for Army Special Forces (JTT B) and a reduced size JTT for use on airborne platforms (JTT A). These and other configurations would be part of the JTT family of terminals, but they are not currently in production.

The ASAS CCS will receive the AN/USR-55, a full duplex data/half duplex voice version of the JTT Hybrid (JTT/H3), and the Joint STARS GSM will integrate the AN/USR-6, a receive only version of Hybrid (JTT/H-R3). Currently, the CTT/Hybrid Receive-Only (CTT/H-R) 2 channel system (AN/USR-5) is being fielded with the GSM; however, these systems will ultimately be replaced by the JTT. The United States Air Force (USAF) Contingency Airborne Reconnaissance System (CARS), the Army GUARDRAIL IPF, and tactical units in the TRIXS net use the JTT/H-R to disseminate information. The JTT/H-R also provides the commander access to theater and national intelligence through the TIBS and TRAP.

CTT1 has one channel, transmits and receives TRIXS. CTT2 has two channels, receives TRIXS, TIBS, TRAP and TADAX-B. CTT3 has three receive and one transmit channels. It receives TRIXS, TIBS, TRAP and TADAX-B, it transmits TRIXS and TIBS. JTT has ten receive and two transmit channels. It receives TRIXS, TIBS, TRAP and TADAX-B, it transmits TRIXS and TIBS. The JTT will provide interoperation with the future IBS networks. JTT terminals are composed of Common IBS modules (CIBS-M). JTT terminals will be connected to host systems and stand-alone configurations may also be provided. CIBS-M modules may be integrated directly into systems other than JTT terminals on a module-by-module basis.

TRANSPORTATION CHARACTERISTICS / LIMITATIONS: The JTT and CTT are integrated into other weapon systems and are transported with the host system. The equipment can be mounted in fixed and rotary wing aircraft, surface, and fixed or mobile ground platforms and vehicles.
