Sanctions that prevent Russia from obtaining electronic parts have taken a “bite” out of its ability to replenish precision-guided weapons, a Pentagon official said.

The official, who is not authorized to speak publicly about intelligence assessments, said there are signs that Russian supplies of precision weapons are dwindling, forcing the Russians to rely on older bombs that are not guided to their targets with satellites or lasers, the official said. So-called “dumb bombs” are being dropped in Mariupol, causing hundreds of civilian deaths and devastation to homes and businesses.

The assessment, revealed Tuesday, came as the House of Representatives passed a package of about $40 billion in additional aid money for Ukraine, $7 billion more than President Joe Biden requested from Congress.

“The additional resources included in this bill will allow us to send more weapons, such as artillery, armored vehicles, and ammunition, to Ukraine,” Press Secretary Jen Psaki said in a statement Tuesday night. “And they will help us replenish our stockpile and support U.S. troops on NATO territory.”

The bill now goes to the Senate – and Biden urged passage as soon as possible, saying he has “nearly exhausted” the existing aid money for Ukraine.
