The aid includes the first shipment of a precision-guided glide bomb called the Joint Standoff Weapon, with a range of up to 130 km. The medium-range missile gives Ukraine a major upgrade to the weapons it is using to strike Russian forces, allowing the Ukrainians to do it at safer distances.

Fighter jets will drop the bomb, which can strike targets with high accuracy. Biden will not announce that Washington would let Ukraine use U.S. missiles to hit targets deeper in Russia, a U.S. official said.

Supporting Ukraine, which Russia invaded in February 2022, has been a U.S. top priority, Biden said in a statement.

"That is why, today, I am announcing a surge in security assistance for Ukraine and a series of additional actions to help Ukraine win this war," said Biden, who leaves office in January.

The bulk of the new aid, $5.5 billion, is to be allocated before Monday's end of the U.S. fiscal year, when the funding authority is set to expire. Another $2.4 billion is under the Ukraine Security Assistance Initiative, which allows the administration to buy weapons for Ukraine from companies rather than pull them from U.S. stocks.

This will provide Ukraine with additional air defense, unmanned aerial systems, and air-to-ground munitions, as well as strengthen Ukraine’s defense industrial base and support its maintenance and sustainment requirements, Biden said.

Under his plan, the president said, the Defense Department will refurbish and provide Ukraine with an additional Patriot air defense battery and more Patriot missiles.

Biden also ordered the Pentagon to expand training for Ukrainian F-16 pilots, including by supporting the training of an additional 18 pilots next year.

Ukraine's defense has largely received bipartisan support in the U.S., but it was not clear how many Republicans would make time to sit down with Zelenskyy amid rising criticism of his government from party leaders, including Donald Trump, the Republican presidential candidate.
