The United States has approved a potential $108.1 million foreign military sale to Ukraine to help sustain the country’s HAWK air defense systems, the State Department announced this week.
The HAWK, or Homing All the Way Killer, is a U.S.-made medium-range air defense system that Ukraine has used to defend against Russian missile and drone attacks.
The proposed package is intended to keep the systems in operation by providing equipment and services, including spare parts and technical, software and contractor engineering support, the State Department said in a statement Thursday.
“This proposed sale will support the foreign policy and national security objectives of the United States by improving the security of a partner country that is a force for political and economic stability in Europe,” the State Department said.
The Defense Security Cooperation Agency notified Congress of the proposed sale, which must still be approved before it can proceed.
The principal contractor will be Sierra Nevada Corp. of Englewood, Colo.
More than four years after Russia launched its full-scale invasion of Ukraine in February 2022, fighting continues with both sides regularly launching long-range drone and missile strikes.
The Trump administration temporarily paused military aid and intelligence sharing with Ukraine in March 2025 while reviewing its policy toward the war, though some assistance later resumed and the United States has continued approving certain military support packages for Kyiv, according to Reuters.
The U.S. began shipping HAWK interceptors to Ukraine in 2022, Reuters reported. In 2024, the State Department approved a $138 million package for HAWK sustainment and upgrades, including missile recertification, refurbishment work and spare parts.
Washington has provided more than $66 billion in defense articles and services to Kyiv between the start of the invasion and December 2025, according to the latest figures posted on the website of the Special Inspector General for Operation Atlantic Resolve, a U.S. European Command military operation aimed at deterring Russia and reassuring NATO allies in eastern Europe.
According to the State Department, that aid has included Patriot and National Advanced Surface-to-Air Missile System (NASAMS) air defense systems, High Mobility Artillery Rocket Systems (HIMARS) rocket launchers, Abrams tanks, Bradley Fighting Vehicles, Stinger anti-aircraft missiles, Javelin anti-armor systems and Army Tactical Missile System (ATACMS) long-range missiles.
