Joint Fires Network (JFN)

The Joint Fires Network program, managed by the Defense Information Systems Agency (DISA), is a research, development, test, and evaluation (RDT&E) initiative under Program Element (PE) 0305282K. The primary goal of the Joint Fires Network is to develop a resilient, interoperable, and flexible network architecture that supports joint and combined warfighting operations. This architecture is intended to enable efficient and secure transport of Joint Fires data across strategic and tactical levels, particularly in environments that are contested, disconnected, denied, intermittent, or have limited bandwidth (DDIL).

The program's objectives for FY 2026 include the development and deployment of a scalable and secure network infrastructure for Joint Fires Network nodes and centers, with a specific focus on the USINDOPACOM theater. The network will incorporate redundancy and security measures to ensure continuity of operations even under adverse conditions. A key technical objective is the implementation of dynamic software-defined networking, which allows the network to adapt rapidly to changes in the operational environment, thereby enhancing mission effectiveness and survivability.

The FY 2026 funding profile is justified by the need to assess and enhance mission command and planning applications that support workflows across multiple echelons. The initial focus will be on improving situational awareness and targeting capabilities, which are critical for effective joint fires coordination. These enhancements will facilitate more timely and accurate decision-making, supporting both strategic and tactical operations in complex operational theaters.

Within the program, several specific development lines are planned. The initiative to integrate Joint Fires Network nodes with the Defense Information Systems Network (DISN), scheduled to run from Q3 FY 2026 to Q3 FY 2028, aims to improve connectivity and data sharing across the Department of Defense. This integration is expected to bolster network resiliency and ensure that joint fires data can be transported securely and efficiently between disparate operational centers.

Another planned effort, scheduled for Q2 FY 2027 through Q3 FY 2028, will focus on strengthening the network's edge capabilities, enabling nodes at the tactical edge to operate effectively even in DDIL environments. By enhancing resiliency at the edge, the program seeks to ensure that mission-critical data remains accessible and actionable, even when connectivity to central networks is degraded or unavailable.

A subproject scheduled from Q4 FY 2027 to Q3 FY 2028 will address the need for multi-level security (MLS) solutions to support coalition operations. This component will enable secure information sharing among U.S. and coalition partners while maintaining strict data protection protocols. The objective is to facilitate joint fires coordination in multinational environments, where secure and interoperable communications are essential for mission success.
