Ukrainian Presidential Advisor Oleksandr Kamyshin stated on September 15 that Ukraine has started domestic serial production of 155mm artillery shells.[18] Kamyshin stated that Ukrainian production of defense products doubled while he oversaw the Ministry of Strategic Industries (March 2023 to September 2024) and will triple by the end of 2024.
