Ukraine isn't 'one system away from some massive breakthrough,' but there are things it can't get enough of, White House official says

• A White House official says Ukraine needs a consistent flow of capabilities, not one decisive weapon, to defeat Russia.
• Russia is believed to be producing artillery shells three times faster than Ukraine's NATO partners.
• The US is co-producing with Kyiv to boost defense industry and compete with Russia.

Deputy National Security Advisor Jonathan Finer said there isn't a specific single weapon Ukraine needs to defeat Russia. Instead, Ukraine needs a consistent flow of certain capabilities.
