Newly announced work in Huntsville will help bolster the air defenses of a key U.S. ally in Europe.

Northrop Grumman Systems Corp. was recently awarded $481,329,816 for updates and improvements to its Integrated Air and Missile Defense Battle Command System’s software, according to the Department of Defense. Work will be performed in Huntsville, as well as McLean, Va.; Linthicum Heights, Md.; and Orlando, Fla., with an estimated completion date of Dec. 30, 2029.

The lion’s share — $347.6 million – comes via foreign military sales funds from Poland, which made an early commitment to the technology.
