Denmark secured authorization for an $8.5 billion acquisition of Integrated Battle Command System-enabled Patriot units, including a wide range of missiles, radars, engagement control stations, and supporting equipment, while Ukraine obtained approval for $179.1 million in sustainment services for its existing Patriot systems.
