Despite acknowledging that the US has almost no visibility into what happens to American weapons supplied to Ukraine (they might as well disappear into a black hole), President Joe Biden is planning to announce even more security assistance to Ukraine during remarks from the White House on Thursday.

It has been reported that the Biden Administration is preparing an additional package of approximately $800 million following a similarly sized package sent earlier this month. 

That package included artillery and anti-artillery radar for the first time. The White House is searching for strategies to help deliver the military aid to Kiev as quickly as possible because the White House and Biden's military advisers believe the conflict has reached a 'critical stage'.
