Andriy Yusov, a spokesman for the Main Intelligence Directorate of Ukraine’s Defense Ministry, Russia was producing about 50 Iskanders per month and was also increasing its stockpile of other types of missiles. This appears to align with RUSI’s conclusion.In addition to upgrades, Russia will produce 750 Iskander-M and 560 X-101 cruise missiles for 2025, according to RUSI. That's like 62 Iskanders and 46 X-101 per month. The explosive warhead is doubled for the Iskander and improvements are made to the X-101's optical guidance system and trap shooting system to defeat SAMs.
