Ukraine Intelligence Estimates Russia Has 140 Su-34s Left After Recent Strikes

Key points

• DIU estimates Russia has 140 Su-34s in service, including upgraded Su-34M variants, as of October 22, 2026.
• Russia has lost 43 Su-34s destroyed and seven damaged since the start of the full-scale invasion.
• On October 29, a strike on the Marinovka airfield in Volgograd region destroyed two Su-34s and killed two servicemen.
• Zelenskiy stated Ukraine has intelligence regarding new Russian ballistic missile preparations and requires more Patriot missiles.
• DIU notes that replacing lost Su-34s is difficult due to a production capacity of only 14-18 aircraft per year.

Background

This development follows a series of Ukrainian strikes on Russian airfields in October 2026. On October 14-15, Ukraine claimed the destruction of six Su-34M bombers at the Borisoglebsk airfield in Voronezh region using Neptune missiles, a claim Russian officials denied. These recent losses add to the cumulative toll reported by Ukrainian intelligence, highlighting the strain on Russia's aviation replacement capabilities.

How outlets are covering it

Ukrainian sources, including the Defense Intelligence Unit and President Zelenskiy, emphasize the strategic impact of recent strikes on Russian air power and the difficulty Russia faces in replacing lost aircraft. Ukrainian naval forces confirmed the destruction of two Su-34s at the Marinovka airfield. In contrast, Russian state corporation Rostec announced the delivery of a new batch of Su-34s in October but did not specify the number, suggesting an effort to maintain fleet size despite losses. Russian officials have previously denied specific strike claims, such as the Voronezh incident, citing only minor damage from intercepted drones.

Why it matters

The depletion of Russia's Su-34 fleet impacts its ability to conduct sustained strike operations against Ukrainian frontline settlements. The high cost and long production cycle for these aircraft mean that continued losses may degrade Russian tactical air capabilities, potentially shifting the balance of air power in the conflict. Zelenskiy's request for more Patriot systems underscores the urgency of countering anticipated Russian missile strikes while Ukrainian forces continue to target Russian air assets deep within its borders.

What to watch

Ukraine expects to receive decisions regarding additional air defense weapons, specifically Patriot missiles, from Western allies. Russia is likely to continue producing and modernizing Su-34s to replace losses, though this process is constrained by production capacity and technological component availability. Further Ukrainian strikes on Russian airfields may result in additional Su-34 losses, while Russia may prepare new ballistic missile strikes as indicated by Ukrainian intelligence.
