"The Javelin system will help Ukraine build its long-term defense capacity to defend its sovereignty and territorial integrity in order to meet its national defense requirements," it said.
Ukraine’s government has asked to buy 210 Javelin missiles and 37 Javelin Command Launch Units, the statement said. The prime contractor will be a joint venture of Raytheon Co and Lockheed Martin Corp, it added.
The United States said in December it would provide Ukraine with defensive weapons.
Since Moscow’s annexation of Crimea in 2014, Ukraine and Russia have been at loggerheads over a war in eastern Ukraine between pro-Russian separatists and Ukrainian government forces that has killed more than 10,000 people in three years.
Ukrainian President Petro Poroshenko said in December the weapons would be used to protect Ukrainian soldiers and civilians, but Russia said the U.S. decision would encourage those who support the conflict in Ukraine to use force.
