The Biden administration announced a new weapons package for Ukraine worth $150 million, as the war-weary country enters its 11th week of conflict with Russia.

The Pentagon said the next tranche of weapons will include 25,000 155mm artillery rounds, three AN/TPQ-36 counter-artillery radars and electronic jamming equipment.

The latest military aid package, the ninth security assistance installment, brings the U.S. military aid commitment to $3.8 billion since Moscow invaded its neighbor in late February.

The $150 million pledged on Friday comes from the remaining $250 million in presidential drawdown authority, which allows the president to transfer excess weapons from U.S. arsenals without congressional approval.

Last month, Biden requested $33 billion from Congress after he exhausted his remaining drawdown authority. He reiterated his request on Friday by saying that for Ukraine to succeed against Russia, the U.S. and its allies must continue to flow weapons and ammunition into the country.
