The US Army has introduced a new mortar fire control application that allows soldiers to operate mortar systems directly from smartphones and tablets.
Designed to replace older laptop-based software, the app simplifies battlefield operations and speeds up access to major fire control functions.
The system marks a major step in the Army’s effort to modernize artillery technology with more flexible and user-friendly digital tools.
Known as the Mortars App, the software works on multiple operating systems, including Android and Windows. This allows units to use a wider range of devices already available in the field. The app combines several fire control functions into one integrated platform.
Mortars are indirect-fire weapons used to strike targets from a distance. Fire control software helps crews calculate aiming data and coordinate engagements. By placing these functions on mobile devices, the Army aims to improve speed and ease of use during missions.
The application was built using a modern software architecture designed for reliability and future upgrades. According to the Army, the system features a simple interface that soldiers can learn quickly. The design also makes it easier to add new capabilities over time.

Unlike traditional fire control programs, updates to the Mortars App require fewer resources and less development effort. This allows improvements to reach operational units faster. The approach supports the Army’s broader modernization strategy across combat systems.
The project is led by computer engineer Julia Gustafson and her development team. She said additional software advancements are already in development. These future enhancements are expected to expand the app’s capabilities and improve battlefield performance.
Mortar App Modernizes Battlefield
Planning for the Mortars App began in 2020 as part of a broader effort to modernize artillery fire-control systems. Development was completed ahead of schedule in 2023 alongside related Army software programs. Early versions lacked some features but were still considered ready for field use.
Soldiers testing the first releases reported that the software performed better than expected. Many users highlighted the advantages of its modern design and flexibility. Their feedback helped developers refine the system and improve interoperability.

The latest version, known as Version 4.0, entered service in 2024. Troops familiar with older mortar software adapted quickly with minimal training. Users have praised the app for making fire control tasks more efficient while maintaining the core functions they already understand.
The introduction of the Mortars App reflects a growing shift toward mobile-based military technology. As digital tools become more important on the battlefield, systems that are easier to deploy, update, and operate are gaining strategic value. Future upgrades are expected to further strengthen the Army’s ability to deliver faster and more effective fire support.
