MOD of In-Svc Equipment (ENFIRE)

The MOD of In-Svc Equipment (ENFIRE) program is a line item within the Army's Other Procurement budget, specifically under Communications and Electronics Equipment for Tactical Command and Control Systems. The primary objective of this program is to modernize and sustain the Army's family of survey and reconnaissance equipment, which is essential for supporting homeland defense, domestic emergency response, and military support to civil authorities. The program addresses the need for updated, interoperable, and secure engineering tools for both active and reserve components, ensuring mission readiness and operational effectiveness.

ENFIRE (Instrument Set Reconnaissance and Survey) is the central component of this line item. Its goal is to automate and enhance the Army's ability to conduct reconnaissance, route clearance, obstacle reporting, construction management, survey support, and terrain analysis. ENFIRE leverages Commercial Off The Shelf (COTS) technologies to capture, process, and disseminate critical data via secure tactical communications systems, such as SIPR/NIPR networks and Blue Force Tracker 2. The system is designed to be interoperable with Army Mission Command and USMC C2PC, supporting rapid and accurate decision-making in the field.

The modernization of ENFIRE is justified by its ability to replace outdated analog methods, reduce time on target, and enable operations from safer, stand-off positions.

GLOBAL POSITIONING SYSTEM - SURVEY (GPS-S) is another key element of this procurement line. GPS-S provides precise geodetic, topographic, and hydrographic survey capabilities using both military and commercial GPS signals. Its objectives include supporting independent navigation, local area differential GPS, and precise point positioning for a variety of military engineering tasks. The system delivers sub-meter and centimeter-level accuracy, which is critical for targeting, navigation, and construction operations.

The modernization and procurement of GPS-S ensure that Army units have access to reliable and precise positioning information, which is vital for mission planning and execution.

AUTOMATED INTEGRATED SURVEY INSTRUMENT (AISI) is a COTS electronic transit theodolite integrated with electronic distance measurement technology. The main goal of AISI is to provide high-precision measurement of vertical and horizontal angles and distances, supporting the creation of topographic maps and control points. This capability is especially important in environments where GPS is unavailable or degraded, allowing Army surveyors to maintain operational effectiveness. The procurement and modernization of AISI systems ensure that the Army can generate accurate terrain data for targeting, construction, and design operations.

The tech refresh kits funded by this line item are composed of COTS components that replace equipment reaching the end of its service life. The recurring technical refresh is critical for maintaining a strong security posture, ensuring interoperability with Army enterprise systems, and supporting rapid adoption of emerging technologies. The program's procurement strategy enables the Army to keep pace with technological advancements and evolving mission requirements, while also reducing lifecycle costs and logistical burdens.

The FY 2026 budget request supports the technical refresh of up to 165 ENFIRE systems, distributed among the active Army, Army National Guard, and Army Reserve. This investment is aligned with the Army Acquisition Objectives for each system. The program's distributed procurement ensures that all components of the Army have access to modernized survey and reconnaissance equipment, supporting both routine operations and contingency missions.
