Warfighter Information Network-Tactical (WIN-T) is the Army's current and future tactical communications network backbone, delivering seamless, assured mission command, advanced communications and a comprehensive common operating picture in support of joint, coalition and civil missions worldwide. As part of the Army’s “ONE TACTICAL NETWORK,” WIN-T Increment 1 establishes an at-the-halt network backbone that provides the full range of data, voice and video communications to command posts at the battalion and above echelons, using both line-of-sight (LOS) and beyond-line-of-sight (BLOS) communications nodes.
WIN-T Increment 1 comprises over 90 percent of the Army’s tactical network. The Army began fielding WIN-T Increment 1, formerly known as the Joint Network Node Network, in 2004 and completed fielding in 2012. To support expanding network requirements and improve the readiness of today’s operational force, the Army is fielding several major upgrades to WIN-T Increment 1 that provide increased throughput and interoperability while hardening cyber security.
Recent upgrades added Network Centric Waveform (NCW) capability, which is a dynamic robust waveform that optimizes bandwidth and satellite utilization. One of the key attributes of NCW is that it facilitates communication between the at-the-halt WIN-T Increment 1 and the on-the-move Increment 2, increasing interoperability so the two generations of equipment can "talk" seamlessly on the battlefield. The Army is also fielding an enhanced Network Operations (NetOps) tool suite across both increments of its tactical network to provide communications officers (S6s/G6s) with a common operating picture of the network and enable units to simultaneously plan and manage across the increments as one network. Providing a common set of NetOps tools is a unifying force that helps bring the network together holistically. The enhanced NetOPs simplifies and reduces the number of network management tools that S6s/G6s use to manage the tactical communications network.
- WIN-T Increment 1 has three main transportable network nodes that provide high-speed wide area network capability for secure voice, video and data exchange. The Tactical Hub Node (THN) supports division headquarters; the Joint Network Node (JNN) supports brigade level headquarters; and the Battalion Command Post Node (BnCPN) supports battalion level headquarters. The fourth type of node, the Regional Hub Node (RHN), is a fixed installation equivalent to three THNs and is used to support theater level operations.
- The Satellite Transportable Terminal (STT) is a highly transportable and mobile satellite system, which operates in conjunction with the JNN and BnCPN, designed to establish secure voice, video and data communications virtually anytime and anywhere.
- The Single Shelter Switch (SSS), designed for rapid deployment and small footprint, provides “first in” capability and is the building block for network expansion on the battlefield.
- The High Capacity Line Of Sight (HCLOS) radio, integrated into a sheltered mounted HMMWV, provides the high data rates required to transport the increasing volume of data on the digital battlefield.
- The legacy Tropospheric Scatter (TROPO) Radio, AN/ TRC-170(V)3 provides BLOS communications, reduces SATCOM demands and offers an alternative long-haul communications method.
- Tactical Network Operations (NetOps) Management System (TNMS) is a scalable, modular NetOps capability that operates on multiple client or server platforms. The TNMS will facilitate decision making necessary to quickly identify network problems, shift resources, change configurations and coordinate the management of the critical network infrastructure supporting mission command functions.
Product Manager WIN-T Increment 1 also manages several programs that significantly improve capability and the expeditionary nature of today’s operational force.
- Enroute Mission Command (EMC)
- Terrestrial Transmission Line Of Sight (TRILOS) Radio
- Troposcatter Transmission (Tropo)
- Secure Cellular (Wi-Fi/4G LTE)
- Commercial Coalition Equipment (CCE)/Modular Communications Node - Advanced Enclave (MCN-AE)
- Battlefield Video Teleconference (BVTC)
- Disaster Incident Response Emergency Communications Terminal (DIRECT)
- Regional Hub Nodes (RHNs)
