US Secretary of State Antony Blinken on Tuesday announced a new $400 million tranche of security assistance for Ukraine, which includes air defense munitions and armored vehicles.

The assistance includes “air defense munitions, artillery rounds, armored vehicles, and anti-armor capabilities, as well as other equipment essential to strengthening Ukraine’s brave forces on the battlefield, helping them retake Ukraine’s sovereign territory, and defend their fellow citizens,” according to a statement announcing the latest drawdown – the 43rd to date.

Blinken also slammed Russia’s withdrawal from the Black Sea Grain Initiative, noting that Moscow “continues to attack Ukrainian ports and grain infrastructure," including in the southern port city of Odesa.

The strikes – the latest in a wave of attacks on Odesa – killed at least one person and injured several others, Ukrainian officials said. At least 25 architectural monuments were destroyed and a historic Orthodox cathedral was badly damaged, a regional military official said.

“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,” Blinken said. “Until it does, the United States and our allies and partners will stand united with Ukraine, for as long as it takes.”According to a State Department spokesperson, some of the specific capabilities in this pacakge are:

• Additional munitions for Patriot air defense systems and National Advanced Surface-to-Air Missile Systems (NASAMS)
• Stinger anti-aircraft systems
• Additional ammunition for High Mobility Artillery Rocket Systems (HIMARS)155mm and 105mm artillery rounds
• Javelin and other anti-armor systems and rockets
• Hornet unmanned aerial systems
• Demolitions munitions for obstacle clearing
• Over 28 million rounds of small arms ammunition and grenades
• Night vision devices and thermal imagery systems
