The Biden administration is set to send its 15th security assistance package to Ukraine, bringing the tally of U.S. military and humanitarian aid to more than $7 billion since Russia invaded Ukraine in late February.
A senior U.S. Defense official, who spoke on condition of anonymity in order to share details of the additional security assistance, said the $400 million weapons package was coordinated with Ukrainian officials and is tailored to the wider Russian assault in eastern Ukraine.
Heavy artillery platforms, like howitzers and High Mobility Artillery Rocket Systems, or HIMARS, sit high on Ukrainian military wish lists.
