Russia will use all its missile stockpile by 2023

A high-ranking official of the US Ministry of Defense said this at a briefing on Monday, Reuters reports.

"They have drawn from (Russia's) aging ammunition stockpile, which does indicate that they are willing to use that older ammunition, some of which was originally produced more than 40 years ago," he said on condition of anonymity.

According to Pentagon estimates, with the same intensity of fire and absence of supplies from other countries—in particular, Iran and North Korea—Russia will exhaust all usable ammunition by the beginning of 2023.

"We assess  that at the rate of fire that Russia  has been using its artillery and rocket ammunition in terms of what we would call fully serviceable artillery and rocket ammunition," official said.

He noted that Russia's use of old stockpiles carries certain risks: "In other words, you load munitions, cross your fingers, and hope that they fire, or when they land, that they explode."
