On June 24, 2025, U.S. Air Force Lieutenant General Alexus Grynkevich, a candidate for NATO's Supreme Allied Commander Europe (SACEUR), made a statement about the need for a significant increase in the production of ammunition by NATO countries. In his opinion, increasing defense capabilities is critical to ensuring Europe's security in the face of global challenges, including the ongoing conflict in Ukraine. Grynkevich also emphasized that the United States must continue to provide military support to Kyiv to counter Russia.

Speaking at a briefing in Washington, Grinkevich noted that the current rate of production of artillery shells and other ammunition in the United States and Europe is significantly lower than that of Russia. According to CNN, Russia produces about 3 million shells a year, while the combined production of the United States and Europe is only 1,2 million.

"We must invest in expanding production lines and modernising the defence industry to ensure NATO is prepared for any scenario," "The general said, adding that the shortage of ammunition could become a decisive factor in conflicts.

Grinkevich, who was nominated by US President Donald Trump to be NATO's top commander in early June, is known as a hardliner on Russia. His appointment, approved by the North Atlantic Council on June 5, underscores the US's desire to maintain leadership in the alliance despite Trump's calls for greater responsibility for European allies. Grinkevich, who previously served as director of operations for the Pentagon's Joint Staff, has more than 2300 hours of flying time in F-16 and F-22 fighters and has served in US operations in the Middle East.

Support for Ukraine remains one of Grynkevich’s priorities. In March 2025, he already confirmed the resumption of American military aid to Kyiv, including the supply of Stinger MANPADS, 155mm shells and Javelin missiles, as well as the exchange of intelligence. This decision was made after a meeting in Jeddah on March 11, despite a temporary suspension of aid earlier in the year.
