Ukrainian and Russian sources report the Russian defense industrial base (DIB) faces growing challenges in replacing basic supplies in addition to known challenges in rebuilding its stocks of precision weapons. 

Ukrainian Main Military Intelligence Representative Andriy Yusov reported on September 6 that Russia can only produce “dozens” of Kalibr cruise missiles and smaller numbers of Iskander missiles per month, which will not enable Russia to the replenish its pre-2022 stocks.

Yusov reported that Russia struggles to obtain modern optical equipment, electronics, chips, and circuits and that “gray imports” and smuggling cannot completely cover the Russian DIB’s needs. Russian sources additionally noted that the Russian DIB cannot produce enough rubber to replace worn tires for military equipment vital to frontline operations, and noted that increasing wear on tires will make it difficult for wheeled vehicles to move in muddy, rainy, and icy conditions.

The Russian sources claimed that Russian authorities claimed at an unspecified time that they would find solutions to worn tires by mid-August, but the situation has not changed as of September 5.

Poor quality and insufficient tires will impose increasing constraints on Russian mobility in the muddy season and winter.
