Russia has stockpiled 300 Kh-101 and Iskander-K cruise missiles each: How this will affect attacks on Ukraine

Russia has stockpiled over 300 Kh-101 cruise missiles and nearly 300 Iskander-K cruise missiles, which could influence the nature of future attacks on Ukraine, potentially making them more massive.

This is reported by Defense Express analysts, citing data from Ukraine’s Defence Intelligence in response to a request from NV.

By mid-May 2025, the Russian military-industrial complex has significantly ramped up the production of long-range missile armaments. Russia has accumulated over 300 Kh-101 missiles, intended for use by strategic bombers Tu-95MS and Tu-160, as well as nearly 300 Iskander-K cruise missiles.

These figures suggest a potential shift in Russia’s approach to missile strikes on Ukraine, particularly in terms of the intensity and type of munitions used.

Assessment of Russia’s missile production rates (May 2025)

• Iskander-M (ballistic missiles) — 60–70 units/month

• Kh-101 (cruise missiles) — 60–70 units/month

• Kalibr — 25–30 units/month

• Iskander-K — 20–30 units/month

• Onyx/Zircon — 20–30 units/month

• Kinzhal — 10–15 units/month

• Kh-32 — up to 10 units/month

Russia’s missile stockpiles (May 2025)

• S-300/400 missiles — 11,000 units

• Onyx/Zircon — approximately 700

• Iskander-M — 600

• Kalibr — 400

• Kh-101 — over 300

• Iskander-K — nearly 300

• Kh-22/Kh-32 — up to 300

• Kinzhal — over 100

• KN-23 — 60

How Russia will use the missiles: situation analysis

Based on the data, it can be concluded that Russia is focusing on ground-based missiles and air-launched aeroballistic munitions. Given the limited air defense resources in Ukraine, particularly the shortage of Patriot systems, the threat of new massive attacks using high-precision and difficult-to-intercept missiles is increasing.
