One way to help the situation is for Congress to pass the Bipartisan Innovation Act that would propel domestic design and manufacturing of microprocessors, reducing the reliance on foreign supply, Taiclet said. Each Javelin requires about 250 microprocessors, he added. Lockheed is working with partners including Intel Corp. to support the defense industry’s needs.

U.S. President Joe Biden visited the Javelin factory in Troy, Alabama, last week and urged Congress to authorize an additional $33 billion in aid for Ukraine — with lawmakers warning that stockpiles of the U.S. Army and Marine Corps’ premier anti-tank weapon are becoming depleted due to the war.

The self-guided portable missile system — which weighs just 49 pounds (22 kilograms) — has proved invaluable to Ukrainian fighters, who can fire on Russian vehicles from as far as 4,000 meters (2.5 miles) away and then quickly flee. The U.S. has already delivered about 5,000 of the 5,500 Javelins the White House has committed to provide to Ukraine, a senior defense official told reporters last week.
