Since the beginning of a full-scale Russian invasion of Ukraine, the U.S. gradually began to increase production capacity in the area of 155 mm artillery ammunition. [In February 2023](https://defence24.pl/war-on-ukrainie-report-special-defence24/us-produces-above-ammunition-155-mm-for-sil-gun-Ukraine) The Pentagon granted 2 companies - Northrop Grumman Systems and Global Military Products - government contracts worth a full of $522 million to produce specified missiles. This was straight related to the very large usage of this ammunition at the front, where estimates of about 20,000 missiles a day fired by the Russians. By comparison, Ukrainian capabilities usually closed below 10 000 and were frequently within 5 000 pieces per day.
