The new aid package, which was first reported by Reuters, will include for the first time Hornet surveillance drones made by FLIR Systems.

It also includes munitions for Patriot air defense systems and National Advanced Surface-to-Air Missile Systems (NASMS), Stinger anti-aircraft systems, more ammunition for High Mobility Artillery Rocket Systems (HIMARS), Stryker Armored Personnel Carriers and a variety of other missiles and rockets.

The package is funded using Presidential Drawdown Authority, or PDA, which authorizes the president to quickly transfer articles and services from U.S. stocks without congressional approval during an emergency. The material will come from U.S. excess inventory.

This is the 43rd security assistance package approved by the United States for Ukraine. More than $43 billion in U.S. military aid has been provided since Russia's invasion in 2022.

Commenting on the aid announcement, Secretary of State Antony Blinken noted Russia's attacks on Ukraine ports and Ukrainian infrastructure since withdrawing from the Black Sea Grain Initiative last week.

"Russia could end this war at any time by withdrawing its forces from Ukraine and stopping its brutal attacks against Ukraine's cities and people. Until it does, the United States and our allies and partners will stand united with Ukraine, for as long as it takes," Blinken said in a statement.

The Black Sea grain deal was brokered by the United Nations and Turkey a year ago to combat a global food crisis worsened by Russia's invasion. Ukraine and Russia are both leading grain exporters.

Britain said on Tuesday it had information indicating Russia's military might start targeting civilian shipping in the Black Sea, while the European Union pledged to help Ukraine export almost all its farm produce via rail and road.
