Warfighter Information Network-Tactical (WIN-T)

The Backbone Of The U.S. Army's Tactical Network

Today’s soldiers expect to have network access anywhere, anytime. With the General Dynamics-built Warfighter Information Network-Tactical (WIN-T), commanders can communicate on-the-move and soldiers can have their voices heard, their texts received, and their location displayed on a map.

WIN-T is the U.S. Army’s tactical network backbone providing secure voice and data communications for soldiers on the battlefield without the need for fixed infrastructure. By connecting soldiers with their commanders, WIN-T is changing the way the U.S. Army fights by providing life-saving information on-the-move, anywhere in the world. WIN-T enables soldiers to:

  • Stream real-time video over the network
  • View a topographical map of friendly forces
  • Send texts requesting medical assistance
  • Digitally call for artillery support
  • Access mission command apps like CPOF and TIGR

As technology continues to advance, General Dynamics is upgrading WIN-T by making it smaller, more powerful, and easier to use, which allows the U.S. Army’s expeditionary force of today and tomorrow to remain connected and accomplish their missions.

WIN-T Increment 1: Communications At The Halt

Joint Network NodeOriginally known as the Joint Network Node Network (JNN-N) program, WIN-T Increment 1 began fielding in 2004 to support combat missions during Operation Enduring Freedom and Operation Iraqi Freedom. With WIN-T Inc. 1, for the first time in history, the soldiers in the battlefield had a high-speed, interoperable voice and data communications network down to the battalion level. Fielding of WIN-T Inc. 1 was completed to the U.S. Army, National Guard and Reserves in June 2012.

Similar to most Americans' Internet connections at home, but with added security and the ability to network in the most remote environments, WIN-T Inc. 1 provides the U.S. Army's tactical force with secure high speed, high capacity voice, data and video communications "at-the-halt" granting soldiers the ability to quickly communicate with their operations center.

WIN-T Inc. 1 is currently in use by soldiers in the Army, National Guard and Army Reserves. WIN-T Increments 2 and 3 build on the capabilities of Inc. 1 with on-the-move networking and further security, bandwidth and connectivity.

WIN-T Increment 2: Communications On-The-Move

WIN-T-Increment-2-Outside-No-BackgroundThe 10th Mountain Division was the first to have this new capability when it deployed for Afghanistan in July 2013. WIN-T Inc. 2's unique value was immediately recognized, as it provided soldiers with communications even as fixed infrastructure was removed.

On-The-Move: The tactical communication nodes in Inc. 2 are the first step to providing a mobile infrastructure on the battlefield. Consisting of mobile points of presence systems (installed on select vehicles at battalion levels and above, which include four companies of up to 200 soldiers and about 10 to 30 vehicles each), vehicle wireless packages, and the soldier network extension (for Company-level connectivity).

Increment 2 enables mission command from brigade to division to company through a completely ad-hoc, self-forming network. Commanders and select staff now have the ability to maneuver anywhere on the battlefield and maintain connectivity to the network, without the need to stop and set up communications, making them vulnerable to attack.

WIN-T Increment 3: Simplifying, Securing and Expanding the Network

Increment 3 (Inc. 3) is the research and development component of the Warfighter Information Network-Tactical (WIN-T) program. Its mission is to continually build on and improve the full WIN-T portfolio, ensuring the network keeps pace with advancements in technology and security while providing our soldiers with access to timely, relevant and actionable information.

WIN-T Inc. 3 advancements simplify WIN-T "network operations" for greater soldier utility and ease of use. And as threats within cyber space continue to evolve and grow, Inc. 3 ensures the entire WIN-T portfolio remains cyber secure with ongoing upgrades and development of Type 1 encryption for the network.

WIN-T Inc. 3 will also expand the reach of the network to provide a fully mobile and flexible tactical networking capability needed to support a highly dispersed force over isolated areas. This is especially important as the Army transitions to a faster, leaner force to handle future threats and missions across the globe.

With continued network enhancements, Inc. 3 provides a leap forward in network capacity, as well as improvements to the overall reliability and robustness of the network.

Cyber: Protecting and Defending the Network

Cybersecurity and anti-jam capabilities are a critical part of WIN-T. With the amount of voice and data information that can now flow between soldiers on the ground and back up to commanders at higher echelons, protecting and defending the integrity of the network is a paramount concern.

This is also why General Dynamics’ heritage in data security is essential for its part in developing WIN-T and the Soldier’s Network. As security challenges morph and change over time, we will respond to new challenges and upgrade the network’s defenses on an ongoing basis.
