Unified Network Capabilities and Integration: STN


Sustainment Tactical Network (STN) supports secure data transfer for the logistics community -- including logistics, personnel, medical and force protection data -- to enable the rapid delivery of the right supplies and personnel to the right locations on the battlefield.

The evolving STN program provides expeditionary tactical network transport solutions to the combat service support community. Developed for the general purpose user, these rapidly deployable line-of-sight and beyond-line-of- sight network transport systems provide the connectivity needed to enable the exchange of logistics information on the battlefield and worldwide.

The management of the “legacy” logistics network program, known as the Combat Service Support (CSS) network, has been in operation since 2004 and transferred from PEO Enterprise Information Systems to PEO C3T in October 2019. The legacy logistics network runs over a commercial network, completely separate from the Army’s tactical network design. The Army is working to converge the legacy logistics network onto the tactical network, an effort known as Transport Convergence. The eventual modernized and converged logistics network capability will be known as Sustainment Tactical Network (STN).

The modernized STN portfolio will include a suite of local transport solutions that enable current and emerging battlefield logistics automation devices to electronically exchange information via tactical networks. It employs a deployable wireless local area network (LAN) infrastructure, linking Army logistics information system computers in an area several square miles wide. STN Very Small Aperture Terminal (VSAT) ground satellite systems provide tactical network transport for logistics, personnel, medical and force protection data that supports logistics information systems. Current STN VSATs provide a wide area network (WAN) solution that leverage commercial-off-the-shelf, Ku-band, and auto-acquire capability. They are easy-to-use and transit case-based for rapid deployability and mobility.

The STN network provides end-to-end service for Army logistics communications, with worldwide continuity of service from Soldier to server. It supports data exchange for Army Enterprise Resource Planning solutions and applications, including Global Combat Support System-Army (GCSS-Army), Integrated Personnel and Pay System-Army (IPPS-A); Medical Communication for combat Casualty Care (MC4) and General Fund Enterprise Business Systems (GFEBS).
