How Russia Replaces Its Lost Su-34 Jets Amid Heavy Attrition

Ukrainian Naval Forces Target Marinovka Airfield With Long Neptune Missiles

The Ukrainian Armed Forces have destroyed two Russian Su-34 fighter-bombers in a long-range missile strike on the Marinovka military airfield in Russia’s Volgograd region, News.bg reported, citing the Ukrainian agency UNIAN. The strike utilized a long-range modification of the Ukrainian Neptune missile, known as Long Neptune, targeting a facility operated by the 11th Mixed Aviation Regiment of the Russian Aerospace Forces near the settlement of Oktyabrsky.

According to Ukrainian naval forces, the targeted regiment belongs to the 4th Mixed Aviation Division within Russia’s 4th Air Force and Air Defense Army. While a Russian anonymous Telegram channel reported an attack on the airfield on October 29 involving Su-24M bombers, Su-24MR reconnaissance aircraft, and Su-34s alongside two reported fatalities, the exact scale of the damage remains unconfirmed by independent sources, and the Russian Ministry of Defence has not verified the claims.

Main Intelligence Directorate Assesses Total Su-34 Fleet Losses and Production Rates

Ukraine’s Main Intelligence Directorate (HUR) reported that Ukrainian forces have destroyed 47 frontline Su-34 bombers and seriously damaged seven others since the start of the full-scale invasion, according to military analysts at Defense Express. These aircraft serve as the primary platforms for guided aerial bombs utilized in mass strikes against front-line positions and urban areas.

Despite heavy attrition, Russian defense manufacturing continues to replenish the fleet at high volumes. Between October 2025 and October 2026, the Russian army received 22 new Su-34 aircraft, surpassing traditional industrial capacity. Dnes.bg reported that Russia’s total inventory near the end of 2025 included approximately 125 Su-34 and Su-34M bombers, alongside 135 to 140 Su-35S fighters, roughly 20 Su-57s, and 140 to 145 multirole aircraft from the Su-30 family.

Novosibirsk Aviation Plant Manufacturing Pressures and Critical Component Imports

Serial assembly of the Su-34 is concentrated at the Novosibirsk aviation plant, where standard baseline capacity ranges from 14 to 18 airframes annually, with military command prioritizing the upgraded Su-34M variant. Production output must also balance domestic front-line demands against fulfilling a 2019 export contract with Algeria for 19 aircraft, as reported by Defense Express.

Russian manufacturing sustains its accelerated output by relying on microelectronics, navigation systems, electronic warfare equipment, and specialized measurement technology imported through third-party nations. Defense Express concluded that this production pace highlights the pressing need for tightened international sanctions targeting dual-use import networks and strengthened Ukrainian air defense capabilities.
