The U.S. will announce a new security assistance package for Ukraine of about three billion U.S. dollars as early as Wednesday, a U.S. official said on Tuesday, in what would be the single largest tranche to Kyiv since the start of Ukraine crisis.

The package uses funds from the Ukraine Security Assistance Initiative appropriated by Congress to allow the Biden administration to procure weapons from industry rather than taking weapons from existing U.S. weapons stocks.

Speaking on condition of anonymity, the official said the new weapons did not appear to include types of arms that had not been provided previously to the Ukrainian military. The official said the amount and mix of weapons could change before the formal announcement.

Since the start of the Russia-Ukraine conflicts, Washington has provided 10.6 billion U.S. dollars in military assistance to Ukraine.
