S-70 Okhotnik-B is a Russian heavy stealth unmanned combat aerial vehicle developed by Sukhoi within United Aircraft Corporation programs to complement manned fighters such as the Sukhoi Su-57 and strategic aviation assets like the Tupolev Tu-160. Conceived amid post-Soviet modernisation efforts and contemporary unmanned aerial vehicle competition, the aircraft is intended for strike, reconnaissance, and pilot-augmentation roles under doctrines associated with Russian Aerospace Forces modernisation and Serdyukov reforms-era procurement trajectories. Development has intersected with industrial policy initiatives involving United Aircraft Corporation, Rostec, and research institutes tied to the Moscow Aviation Institute and Tupolev Design Bureau.

Design and development

Design and development began within Sukhoi design bureaus leveraging stealth concepts explored by the Soviet Union’s earlier experimental programmes and influenced by foreign platforms such as the Northrop Grumman X-47B, Lockheed Martin RQ-170 Sentinel, and concepts from China’s Chengdu J-20 studies. The programme brought together teams from Mikoyan, Ilyushin, and Yakolev subsidiaries under the United Aircraft Corporation consolidation to align with procurement plans by the Ministry of Defence (Russia). Wind tunnel testing occurred at facilities used by TsAGI while engine integration drew on work by United Engine Corporation and serial powerplants related to the Saturn 117S family. Political support from figures linked to Vladimir Putin’s defence modernisation initiatives and export ambitions coordinated development with research contracts awarded during sessions of the State Duma defence committees.

Technical specifications and avionics

The flying-wing airframe features low-observable shaping and internal bays consistent with stealth objectives pursued by Lockheed Martin and Northrop Grumman programmes, combined with Russian materials research from Rosatom-linked composites initiatives and Koncern Radioelektronika avionics suites. Reported dimensions and mass place it in the heavy UCAV class alongside proposals by Baykar Makina and General Atomics; propulsion testing has employed engines derived from Saturn AL-31 family development work, with future plans to use higher-thrust turbofans influenced by Salyut design centres. Avionics integration includes multifunction sensors and datalinks intended to network with Sukhoi Su-57 fighters, A-50 Mainstay systems, and command nodes used by Russian Aerospace Forces tactical networks; secure communications aim to interoperate with GLONASS and encrypted links overseen by specialists previously associated with Roscosmos research. Flight-control software development involved teams with experience from MiG-31 upgrade projects and autonomous algorithms referencing work from Higher School of Economics-affiliated laboratories.

Operational history and testing

Initial taxi trials and first flight milestones occurred at Komsomolsk-on-Amur and test ranges used by Russian Aerospace Forces; the prototype's maiden sortie in 2019 was observed by delegations from United Aircraft Corporation and the Ministry of Defence (Russia). Subsequent flight-test campaigns took place at Akhtubinsk and other ranges employed in Soviet-era trials such as those used by the Central Aerohydrodynamic Institute (TsAGI) and Chkalov State Flight-Test Center. Testing phases have included weapon-release evaluations and cooperative control trials with Sukhoi Su-57 prototypes, attracting commentary from analysts at institutions like Carnegie Moscow Center and researchers formerly with RAND Corporation and International Institute for Strategic Studies. Program milestones were periodically announced during exhibitions such as MAKS Air Show and Army Forum while budgetary reviews appeared before the State Duma defence budget committees.

Armament and mission capabilities

Armament options under evaluation include precision-guided munitions from domestic lines produced by Tactical Missiles Corporation and internal carriage concepts similar to stealth designs used by Lockheed Martin F-35 programmes. Proposed mission profiles encompass deep strike, suppression of enemy air defenses (SEAD) in coordination with Sukhoi Su-34 and Su-35S assets, intelligence, surveillance and reconnaissance tasks alongside Orlan-10 and strategic ISR platforms like the Tupolev Tu-214SR. The aircraft’s internal bays are intended to carry air-to-surface missiles and guided bombs compatible with Russian ordnance families endorsed by Ministry of Defence (Russia) procurement lists; electronic warfare and signal-intelligence payloads draw on technology developed at KRET and Radioavtomatika-linked enterprises.

Variants and production

Developmental work envisions baseline strike variants, reconnaissance-optimized versions with enhanced sensor suites, and optionally manned/autonomy-upgrade paths resembling concepts considered by United Aircraft Corporation and comparable to modular plans from Northrop Grumman. Production plans have been discussed at industrial assemblies hosted by Rostec with serial manufacture projected at facilities co-located with KnAAPO or Komsomolsk-on-Amur Aircraft Production Association, contingent on funding authorised by the Ministry of Defence (Russia). Scale-up scenarios reference supply-chain coordination with subcontractors such as Klimov and Saturn in engine production, while potential future iterations may incorporate lessons from Su-57 operational feedback.

Export proposals and international interest

Though primary intent remains national service with Russian Aerospace Forces, export interest and diplomatic discussions have been reported with partners engaged in defence cooperation such as India and prospective outreach to states aligned with S-400 Triumf purchases. Proposals for foreign sales would involve export controls regulated by agencies associated with Rosoboronexport and intergovernmental agreements similar to prior deals for MiG-29 and Su-30 families. International analysts from Stockholm International Peace Research Institute and commentators at Jane's Information Group have tracked the programme as part of broader shifts in unmanned combat aviation markets across Europe, Middle East, and Asia regions.
