The U.S. State Department says it will approve the potential sale of upgraded Patriot missile systems to Ukraine.

In a release on Tuesday, the State Department said it will green-light a proposed sale of upgraded Patriot missile systems to Ukraine.

"This proposed sale will support the foreign policy and national security objectives of the United States by improving the security of a partner country that is a force for political stability and economic progress in Europe," the statement read.

The total value of the sale is estimated at $105 million.

The release noted that the sale of missiles would not negatively affect U.S. defense readiness.

This is a developing story and will be updated.
