The United States is sending additional military assistance to Ukraine - White House 

An initial four units of the rocket system have already been delivered

The $450 million shipment includes additional rocket systems to use against Russian invasion forces, Qazet.az reports.

“This package contains weapons and equipment, including new High Mobility Artillery Rocket systems,” White House spokesman John Kirby said.

Other military equipment includes tens of thousands of rounds of artillery ammunition as well as patrol boats.

The rocket systems known as HIMARS are at the top of Ukraine’s wish list as it attempts to fight off Russian forces advancing through the east of the country with the help of a significant advantage in heavy artillery.

With the latest shipments, the US contribution to Ukraine’s military will amount so far to $6.1 billion, Kirby said.
