One of the main U.S. allies in Europe is deepening its commitment to an integrated air and missile defense system that is made primarily in Huntsville.

Northrop Grumman Corp. announced this week it had secured an $899.6 million contract to supply its Integrated Battle Command System (IBCS) to Poland’s short- and medium-range air defense programs. The arrangement will help Polish and U.S. forces operate better together, the company said, creating in the former nation, “one of the world’s most advanced air defense systems.”

“Expanding IBCS capabilities will keep the U.S. Army and U.S. allies, such as Poland, ahead of evolving threats and capabilities, giving warfighters more decision time to save lives,” said Kenn Todorov, vice president and general manager for global battle management and readiness at Northrop Grumman, in a news release.

IBCS is a next-generation command-and-control system for anti-air and anti-missile units. The Army selected Northrop Grumman as prime contractor in 2010, and the system was authorized for full production in 2023.

IBCS will be deployed to Army units and will also form part of Guam’s air and missile defense efforts. In 2018, Poland became the first U.S. ally to adopt IBCS, according to Northrop Grumman.

The recently awarded contract follows a $4 billion military sale agreement with Poland, announced in 2023, for IBCS and related equipment. The country said its first medium-range missile-defense battery passed a key operational milestone in December.

Northrop Grumman in Huntsville was awarded a $1.38 billion contract in 2021 to produce the IBCS, according to an AL.com report. The company employs about 2,000 locally.

Its footprint has been expanding in the Rocket City recently, with a facility to support the Air Force’s ICBM program opening in Cummings Research Park in 2021 and a $100 million expansion at Redstone Gateway coming online in 2023.

Northrop Grumman was awarded a separate contract in January valued at $481 million for software improvements to IBCS, The Huntsville Times reported.
