HUNTSVILLE, Alabama, — June 11, 2026 : The U.S. Department of Defense has awarded Northrop Grumman Systems Corp. a $30.76 million contract modification to provide sustainment and logistics support for Poland’s WISLA Integrated Air and Missile Defense Battle Command System (IBCS).
The contract modification was awarded by the U.S. Army Contracting Command at Redstone Arsenal, Alabama, and increases the total value of the sustainment agreement to approximately $78.4 million. The work will be performed primarily in Huntsville, Alabama, and is scheduled for completion by December 31, 2029. Funding is being provided through Fiscal Year 2026 Foreign Military Sales (FMS) funds from Poland.
The WISLA program is Poland’s national effort to establish a layered air and missile defense capability capable of countering ballistic missiles, cruise missiles, aircraft, and other aerial threats. The system combines the Patriot air defense system with Northrop Grumman’s Integrated Battle Command System (IBCS), creating a networked command-and-control architecture that links sensors and interceptors across multiple platforms.
Unlike traditional air defense systems that rely on individual radars, IBCS enables operators to use data from multiple sensors, including ground-based radars and airborne surveillance assets, to create a unified air defense picture. The system allows any connected interceptor to engage a detected threat, improving coverage, flexibility, and resilience if individual sensors are disrupted or destroyed.
Poland became the first U.S. ally to acquire and deploy IBCS. Following the achievement of Initial Operational Capability (IOC) in 2024, the Polish Ministry of National Defense declared Full Operational Capability (FOC) for the IBCS-enabled WISLA system in December 2025. The system is considered one of the most advanced integrated air defense networks within NATO.
Under the modified contract, Northrop Grumman will provide ongoing support for the WISLA network, including materials maintenance, threat library updates, engagement algorithm improvements, communications support, hardware sustainment, and Air Defense Artillery Reconfigurable (ART) training. The company received the contract on a sole-source basis as the original developer of the IBCS architecture.
Poland’s investment in the WISLA program is part of a broader military modernization effort driven by regional security concerns. The country shares borders with Russia’s Kaliningrad exclave and Belarus and has accelerated defense spending since 2022. Poland plans to allocate approximately 4.8 percent of GDP to defense in 2026, the highest level among NATO member states.
The WISLA program currently includes Patriot-based air defense batteries, with plans for further expansion through additional launchers, interceptors, and advanced radar systems. Parts of the program are also being produced in Poland under industrial cooperation agreements.
The U.S. Army declared IBCS Initial Operational Capability in 2023 and began fielding the system domestically in 2024. Northrop Grumman continues to support both U.S. and international IBCS programs, including Poland’s WISLA and NAREW air defense initiatives.
The latest contract modification ensures continued operational readiness and modernization of Poland’s WISLA air and missile defense network through the end of 2029.
