The amount includes a drawdown of around $200 million in weapons and a Pentagon allocation of another $1.5 billion in security assistance money.
The White House has prepared around $1.7 billion in new weapons and military funding for Ukraine.
The Department of Defense (DOD) also announced another $1.5 billion in funds for the Ukraine Security Assistance Initiative. This funding, the department said, will help Ukraine sustain weapons systems that the United States has already allocated.
The DOD said the $200 million weapons package would include new shipments of National Advanced Surface-to-Air Missile Systems, various short and medium-ranged air defense munitions, new High Mobility Artillery Rocket Systems, 155 mm and 105 mm tube artillery shells, 120 mm mortar rounds, various anti-tank missile launchers and anti-tank missiles, small arms, explosives and demolition equipment, communications equipment, electronic warfare equipment, and other spare parts and maintenance tools.
This latest package of weapons and funding for Ukraine draws from the approximately $61 billion that Congress allocated for Ukraine in April.
“Since the national security supplemental passed Congress in late April, President Biden and the United States government has delivered for Ukraine,” Mr. Kirby said.
“The president has authorized nine security assistance packages since late April, and the men and women of our armed forces have been working around the clock to get those weapons and that equipment into Ukraine as quickly as possible.”
Mr. Kirby said the aid has helped Ukrainian forces shore up their defenses and stave off fears of a major Russian strategic breakthrough on the battlefield.
Although battlefield reports suggest Russian forces are making incremental advances, the White House spokesman said those Russian forces are paying “extraordinary costs” in terms of personnel losses for “very little gain.”
This past week, the European Union transferred $1.6 billion to Ukraine, drawing from frozen Russian assets.
“The Biden–Harris administration will continue to work together with more than 50 allies and partners in the global coalition that we’ve assembled to help Ukraine prevail against Russia’s aggression,” Mr. Kirby said on Monday.
