The U.S. Army has announced the award of contracts worth $522 million to two companies to manufacture artillery ammunition for Ukraine. The orders went to Northrop Grumman Systems and Global Military Products and come amid worries that Ukraine was fast depleting its stockpiles of artillery shells. Deliveries of the new ammunition are scheduled to begin in March, the army said in a statement on February 14. The contracts are funded by the Pentagon's Ukraine Security Assistance Initiative.
