Shipments of American weapons could begin flowing to Ukraine again soon after House approval of a long-stalled aid package, U.S. officials say, with goods from the Pentagon’s stockpiles in Germany shipped quickly by rail to the Ukrainian border.

The measure would provide the Ukraine war effort with about $60 billion. A sizable amount is set aside to replenish U.S. defense stockpiles, and billions more would be used to purchase U.S. defense systems, which Ukrainian officials say are badly needed.

The Senate was expected to pass the legislation, and President Biden has said he would sign it into law.

For months, Ukrainian military officials have complained that political paralysis in the U.S. Congress had created critical munitions shortages in the war against Russia. Ukrainian troops on the front lines have had to ration shells, and morale has suffered.

U.S. officials have not explicitly said which weapons the United States will send to Kyiv as part of the package, but Maj. Gen. Patrick Ryder, the Pentagon press secretary, told reporters on Thursday that more air-defense and artillery ammunition would probably be included.

“We have a very robust logistics network that enables us to move matériel very quickly as we’ve done in the past,” General Ryder said.
