US President Joe Biden’s administration announced Wednesday $325 million in new military aid to Ukraine to support its military in its war against Russia, including additional ammunition for High Mobility Artillery Rocket Systems (HIMARS), advanced missiles and anti-tank mines.

It is the 36th security package for Ukraine since the Russian invasion in February 2022, bringing total US military aid to the Kyiv government to more than $35.4 billion at that time.

“This security aid package includes more ammunition for HIMARS and artillery shells provided by the United States, as well as anti-armor systems, small arms, logistics, support vehicles and maintenance support, essential to reinforce Ukraine’s defenders in the field of battle,” US Secretary of State Antony Blinken said in a statement.

The HIMARS is a truck-mounted missile launcher that can rapidly fire multiple guided missiles. The missiles supplied to Ukraine have a range of up to 80km, and Ukrainian forces have had great success using them to attack Russian positions.

“Russia could end its war today. Until Russia does, the United States and our allies and partners will remain united with Ukraine for as long as it takes,” Blinken stated.

In addition to HIMARS ammunition, the package includes artillery ammunition, TOW (tube-launched, optically tracked and wire-guided) missiles, anti-tank mines, port security equipment and more than 9 million rounds of small arms, according to a spokesman of the Department of State.

The package will be financed using the Presidential Redeployment Authority, or PDA, which authorizes the president to transfer items and services from US reserves without congressional approval during an emergency.
