Biden visits factory making the Javelins Ukraine is using to kill Russian tanks

President Biden is visiting an Alabama Lockheed Martin facility that makes Javelins, the weapon known as a "tank killer." The U.S. has donated more than 5,500 Javelins to Ukraine since the Russian invasion began.

Videos of the missiles destroying Russian tanks have spread online, including by the Ukrainian military. The Javelin is known as the "tank killer" because its top attack capability means it pops up into the air before diving down and targeting the top of tanks, where the armor is the thinnest.  

Mr. Biden's visit on Tuesday comes as the Pentagon and Congress are discussing the long-term impact for the United States of giving so many of these and other weapons to the Ukrainians so quickly.
