The Biden administration is concluding its military aid efforts with a final package worth approximately $500 million for Ukraine.
Details were expected to be provided by Defense Secretary Lloyd Austin during a meeting at Ramstein Air Base in Germany.
The package includes missiles for air defense and equipment for Ukraine's F-16 fighter jets, reflecting US support ahead of possible negotiations to end the conflict.
Despite the ongoing aid, U.S. officials note there are significant manpower issues facing Ukraine, while weapon stocks remain stable.
The announcement coincides with the White House's plans to impose additional sanctions on Russia, reinforcing U.S. commitments before the handover of power.
