Russia Delivers First New Su-35S Fighters of 2026, Signalling Moscow Can Still Sustain Air War Despite Sanctions and Attrition

(DEFENCE SECURITY ASIA) — Russia has delivered another batch of newly-built Su-35S fighters during April, immediately signalling that Moscow intends sustaining tactical airpower pressure despite sanctions, attrition and mounting industrial strain.

The transfer represents the first confirmed delivery of newly-produced Su-35S multirole fighters during 2026, underscoring that Russian combat aviation manufacturing remains functioning after more than two years of uninterrupted wartime demand.

Because the aircraft will reinforce the Russian Aerospace Forces during continuing combat operations, the handover carries broader implications for regional force posture, logistics resilience and Moscow’s long-term military-industrial sustainability.

United Aircraft Corporation, which forms part of Rostec, confirmed on 17 April that the new-production fighters had formally entered service with the Russian Aerospace Forces, commonly known as the VKS.

The aircraft completed a full cycle of factory ground testing and flight evaluations before Ministry of Defence test pilots assessed them across multiple operating modes and mission profiles.

Only after those evaluations concluded were the aircraft ferried from the production facility toward their eventual operational base, following Russia’s established tactical aviation delivery procedure.

A VKS Su-35S pilot stated that the aircraft performs distant interception, strike-group protection, unmanned aerial vehicle destruction, reconnaissance and precision attacks using guided weapons.

Rostec First Deputy Chief Executive Vladimir Artyakov declared that the Su-35S remains among the world’s most effective combat aircraft, citing Russian claims regarding aerial interception performance.

United Aircraft Corporation Chief Executive Vadim Badekha added that unconditional fulfilment of state defence orders remains the company’s overriding priority despite continuing production pressures.

Small Deliveries, Strategic Continuity

Neither Rostec nor United Aircraft Corporation disclosed the exact number of fighters delivered, maintaining a longstanding Russian practice designed to conceal aircraft availability and production rhythms.

Nevertheless, official photographs and short video footage released during the handover visibly showed at least two new Su-35S aircraft taxiing from the production facility.

Independent defence observers studying the footage assessed that the batch likely consisted of two fighters, matching the limited-size delivery pattern established throughout 2025.

That pattern reflects a deliberate Russian preference for smaller but more frequent deliveries, allowing newly-built aircraft to enter service without waiting for annual production completion.

During 2025, United Aircraft Corporation completed seven separate Su-35S deliveries between late March and December, usually occurring at intervals between roughly six and ten weeks.

Those deliveries indicate that Russia preserved an annual Su-35S production rate estimated between seventeen and twenty aircraft despite international sanctions targeting aerospace supply chains.

The April transfer therefore appears less significant because of its numerical size than because it confirms uninterrupted industrial continuity entering a third wartime year.

By distributing deliveries across smaller batches, Moscow can replace operational losses incrementally while simultaneously avoiding production disruptions caused by component shortages or factory bottlenecks.

The approach also complicates foreign intelligence assessments because limited aircraft numbers and redacted tail markings obscure the precise growth of Russia’s frontline fighter inventory.

Why the Su-35S Still Matters

The Su-35S, designated Flanker-E by NATO, remains Russia’s most capable serially-produced non-stealth fighter and occupies a central position within the VKS combat structure.

Russian planners continue valuing the aircraft because it combines long-range interception, multirole strike capacity and advanced air-combat manoeuvrability within a single platform.

The fighter belongs to Russia’s so-called 4++ generation category, representing an extensively modernised evolution of the earlier Su-27 Flanker family.

Its most distinctive feature remains the twin thrust-vectoring engines, which provide exceptional manoeuvrability during close-range combat and difficult interception profiles.

The Su-35S also carries the Irbis-E passive electronically scanned array radar, enabling long-range target detection and simultaneous engagement of multiple aerial threats.

Complementing the radar, the aircraft employs the OLS-35 infrared search-and-track system, allowing passive detection of hostile aircraft without emitting detectable radar signals.

Russian officials additionally emphasise the aircraft’s electronic warfare suite, which is designed to complicate hostile missile guidance and suppress enemy air-defence radars.

The platform can employ a wide range of precision-guided munitions against ground and maritime targets, giving the VKS greater mission flexibility during prolonged operations.

Because of that combination of sensor reach, endurance and multirole capability, the Su-35S remains particularly valuable during large-scale, attritional air campaigns.

Production Under Sanctions Pressure

The newly-delivered aircraft were manufactured at the Komsomolsk-on-Amur Aviation Plant named after Yuri Gagarin, commonly known by its Russian abbreviation KnAAZ.

Located in Russia’s Far East, the plant serves as the principal production centre for the Su-35S and several other advanced tactical aircraft programs.

KnAAZ has operated under significant sanctions pressure since the beginning of the Ukraine conflict because many aerospace components historically depended upon imported technologies.

Despite those restrictions, Russia has continued maintaining output through stockpiled components, supply-chain substitution and the gradual localisation of previously imported systems.

The continuing flow of Su-35S deliveries therefore suggests that Russian aerospace factories still retain sufficient capacity to satisfy immediate wartime procurement requirements.

At the same time, the relatively small size of individual deliveries indicates that production remains constrained compared with peacetime ambitions announced before sanctions intensified.

No new long-term procurement agreement accompanied the April announcement, indicating that these aircraft probably originated from existing state defence orders already underway.

That absence is strategically significant because it suggests Moscow presently prioritises fulfilling current operational commitments rather than unveiling ambitious future expansion programmes.

United Aircraft Corporation consequently appears focused upon maintaining predictable output rates, preserving logistics stability and ensuring uninterrupted support for the VKS operational fleet.

Force Posture and the Ukraine Air War

Although Russian officials avoided directly connecting the delivery with the war in Ukraine, the broader operational context leaves little doubt regarding intended employment.

The Russian Aerospace Forces continue operating under high sortie requirements, particularly for long-range interception, escort duties and precision attacks behind frontline positions.

The VKS pilot quoted during the announcement specifically highlighted missions involving distant interceptions, unmanned aerial vehicle destruction and deep battlefield reconnaissance.

Those mission descriptions closely correspond with Russian combat aviation requirements across the Ukrainian theatre, where drones, dispersed positions and layered air defences dominate operations.

Su-35S fighters have repeatedly been used to escort strike packages, patrol contested airspace and employ long-range missiles against aerial threats.

The aircraft’s ability to identify hostile positions at significant depth from the combat line also strengthens Russian battlefield awareness and targeting coordination.

Because the VKS remains engaged within a sustained attritional conflict, even a two-aircraft delivery materially improves rotational availability and force endurance.

Small reinforcements become especially important when maintenance cycles, combat attrition and pilot training requirements continuously reduce the number of immediately deployable fighters.

Consequently, the April delivery represents not merely an industrial announcement but a direct reinforcement of Russia’s operational airpower posture during continuing conflict.

Strategic Signalling Beyond the Aircraft Numbers

The political messaging surrounding the handover proved almost as important as the aircraft themselves because Russian officials framed the delivery as evidence of resilience.

By publicly announcing another successful transfer, Rostec and United Aircraft Corporation sought demonstrating that sanctions have not halted Russian fighter production.

Artyakov’s description of the Su-35S as one of the world’s most effective combat aircraft reinforced that broader narrative of industrial confidence and battlefield credibility.

Badekha’s emphasis upon state defence orders similarly highlighted that Moscow still considers tactical aviation procurement a strategic national priority.

The carefully-managed release of photographs and short video footage followed the same communication pattern visible during previous Su-35S deliveries throughout 2025.

Those images usually show aircraft taxiing or flying while concealing identifying numbers, balancing propaganda value against operational security concerns.

For external observers, the April announcement therefore delivers two simultaneous messages regarding Russian military power and industrial capacity.

First, it confirms that the Kremlin continues sustaining combat aircraft production even under wartime conditions, sanctions pressure and repeated battlefield demands.

Second, it demonstrates that Russia intends preserving a long-term tactical aviation force structure rather than merely consuming existing fighter inventories.

The continuing delivery rhythm also carries implications beyond the immediate battlefield because Russia must simultaneously preserve pilot conversion, maintenance training and spare-parts availability across an expanding Su-35S fleet.

Each additional fighter requires corresponding stocks of engines, avionics modules, radar components and precision-guided munitions, creating a logistics burden extending far beyond simple aircraft production numbers.

That burden becomes especially significant because Russia is attempting maintaining high operational tempo while supporting aircraft already deployed across multiple military districts and forward operating locations.

Although neither Rostec nor the Russian Ministry of Defence disclosed the financial value of the latest batch, a single Su-35S is commonly estimated internationally at approximately US$85 million to US$100 million.

Using those estimates, even a two-aircraft batch would represent a procurement value between US$170 million and US$200 million, equivalent to roughly RM646 million and RM760 million.

Those figures underline why Moscow continues favouring incremental fighter deliveries because smaller batches distribute financial pressure while preserving stable aircraft output under wartime economic constraints.

The absence of any accompanying announcement regarding larger annual procurement targets nevertheless leaves uncertainty regarding whether Russian fighter production can expand substantially during later stages of 2026.

Until additional deliveries appear, the April handover should therefore be interpreted as evidence of sustained industrial endurance rather than proof of a major increase in Russian tactical aviation capacity.
