The Economist reports that Russia has significantly ramped up its production rate of ballistic missiles, and is now producing approximately 100 units per month, including Iskander-Ms and RM-48U modified S-400s.
Last month, Ukrainian intelligence estimated that Russia produced 65 Iskander-M ballistic missiles in July. If the Ukrainian intelligence and Economist figures are both correct, it would indicate Russia is producing around 35 RM-48U modified S-400 ballistic missiles per month.
When taking into account the new Kn-23 ballistic missiles delivered to Russia by North Korea, Russia now has the capacity to launch weekly medium-sized attacks on Kyiv (~15 missiles per attack) without ever decreasing their total missiles in reserve, while still retaining 40 additional newly-produced missiles, as well as all of their Kn-23 ballistic missiles for attacks on different targets.
For reference, in 2022, it was estimated by Ukrainian intelligence that Russia produced just 3 Iskander-Ms per month. They also did not have any RM-48U modified S-400 or Kn-23 ballistic missiles at this time.
