Air combat keeps evolving, but getting weapons on target first still depends on position—and position favors the jet that can point, turn, and recover faster than the rest. The Su-35 (Flanker-E) was built around that idea. Its airframe, engines, and flight control logic are optimized for post-stall control, high-alpha turns, and rapid nose pointing that compress engagement timelines in close-in fights while preserving energy for the next move.
Dr. Maya Chen, Fighter Dynamics Analyst: “Supermaneuverability is not just airshow flair. In a merge, the ability to hold control beyond the normal stall angle opens firing windows that don’t exist for conventional fighters.”
Su-35 Fighter Jet
The Su-35 is a deep modernization of the Su-27 family with a new digital flight control system, modern cockpit, high-power radar, and thrust-vectoring engines. Compared with earlier Flankers, the Su-35 removes canards, reduces drag, and adds more composite materials. The result is a cleaner airframe with better energy retention and a wider controllability envelope.
Between 2024 and 2026, incremental blocks emphasized mission software, electronic warfare hardening, and weapons integration, while keeping the jet’s signature advantage—3D vectoring—front and center in tactics and training.
Col. (Ret.) Arman Petrov, Former Test Pilot: “What pilots notice first is the jet’s balance. It can pivot aggressively, yet the flight control laws prevent you from painting yourself into a corner.”
Overview Table

Prof. Laura Ibrahim, Aerodynamics & Controls: “Think of the Su-35 as a choreography between vectoring and vortex lift. The flight control system blends both to keep lift and control authority where most jets are out of options.”
Who Should Consider the Su-35
- Mission Profile: Air forces needing air dominance with credible WVR (within visual range) edge and strong BVR reach.
- Training Pipeline: Willingness to invest in high-alpha maneuver syllabi, HMS + HOBS missile tactics, and energy-maneuver decision training.
- Support & Sustainment: Capable maintenance ecosystem for vectoring engines, radar LRUs, and EW systems.
- Doctrine Fit: Forces that value deterrence through agility and endurance, including long-range patrols and complex escort missions.
- Budget & Industry: Openness to local MRO, spare pooling, and simulator infrastructure for high-fidelity maneuver practice.
What Operators Gain?
- Post-Stall Control Windows: The jet can point the nose where the missile needs—even at extreme alpha—then recover energy quickly.
- Symbiosis with HOBS Missiles: Pairing helmet cueing with high-off-boresight missiles turns fleeting nose authority into real kill opportunities.
- Energy Retention: Cleaner aerodynamics and engine thrust mean the Su-35 can regain speed after high-drag moves, ready for the next pass.
- Sensor Fusion for the Merge: IRST + radar + HMS reduce reaction time from detect to cue to shot.
- Deterrent Presence: Long endurance and visible supermaneuver displays contribute to air policing and strategic messaging.
Rina Kapoor, Air Combat Tactician: “The Su-35’s trick is not only to turn harder—it’s to recover faster. That turn-then-sustain cycle is what keeps you alive through multiple merges.”

How the Su-35 Stacks Up?
| Feature | Su-35 | F-15EX | Rafale F4 | F-16V |
|---|---|---|---|---|
| Design Emphasis | Supermaneuverable air-dominance with 3D vectoring | Payload, sensors, range, networked roles | Agility + advanced EW + compact footprint | Cost-effective multirole with modern avionics |
| Maneuver Edge | Post-stall control, high-alpha nose pointing | Strong but conventional (no 3D TVC) | Excellent instantaneous turn; no 3D TVC | Good energy fighter; no 3D TVC |
| Sensors | High-power radar + IRST + HMS | AESA + powerful mission systems | AESA + SPECTRA EW + HMS | AESA + HMS options |
| Best Use Case | WVR dominance with sustained agility and long endurance | Heavily networked strike/air defense | Agile multirole in dense EW theaters | Budget-sensitive air policing and multirole |
| Takeaway | Wins on nose authority + recovery | Wins on payload/networking | Wins on EW agility balance | Wins on cost/upgradability |
Bottom line: If your doctrine prizes merge superiority and kinematic deterrence, the Su-35’s supermaneuverability is a differentiator. If your priority is payload + network effects, F-15EX-style platforms may fit better.
Recent Updates (2024–2026)
- 2024: Mission software refinements enhance high-alpha stability margins and improve HMS-to-missile handoff timing, shortening the shot cycle in close-in fights.
- 2025: EW suite updates add better threat libraries and jam-resilient datalink behavior; cockpit symbology tweaks reduce pilot head-down time during aggressive maneuver sets.
- 2026: Engine and vectoring control logic receive minor updates for smoother nozzle transitions at very high angles of attack, reducing energy bleed during nose-pointing bursts.
“Sable,” Operational Test Pilot (pseudonym): “The latest block feels like a software ‘polish pass.’ Transitions in and out of high-alpha are cleaner, so you spend less time slow and more time setting up the next shot.”
Operational Impact
- First-Shot Windows in the Merge: Post-stall control means shorter time-to-nose-on, converting surprises into valid shot cues.
- Missile Defeat Geometry: 3D vectoring supports abrupt out-of-plane jinks and high-rate break turns, complicating missile end-game solutions.
- Deterrence Through Demonstration: Persistent CAP endurance and visible agility can discourage escalations and bolster air policing credibility.
- Training Multiplier: A jet that rewards skill pushes pilot proficiency, raising the overall standard of an air arm’s WVR tactics.
How the Su-35 Achieves Supermaneuverability?
- Relaxed Static Stability: The aircraft is designed to be naturally “twitchy,” then stabilized by digital flight controls, allowing it to pitch and yaw aggressively without losing control.
- 3D Thrust Vectoring: Engine nozzles steer the thrust, not just the airflow over control surfaces. This keeps control authority even when wings are near stall.
- Vortex Lift & Lifting Fuselage: The airframe generates useful lift at high angles, so the jet can hang the nose and still produce controllable forces.
- Energy Management Logic: The flight computer and pilot technique work together so that after a dramatic move, the jet rebuilds speed and avoids becoming a target.

FAQs
Is the Su-35’s supermaneuverability only for airshows?
No. Post-stall control and high-alpha pointing compress the time to a valid firing solution in real WVR fights.
Does extreme maneuvering bleed too much energy?
It can, but the Su-35’s engines and clean airframe help it recover speed quickly, letting pilots re-enter the fight.
How important is the helmet-mounted sight?
Critical. HMS + HOBS missiles convert brief nose authority into reliable shot opportunities at extreme angles.
Can the Su-35 defend against modern missiles?
Agility aids kinematic defeat, while EW suites and decoys disrupt missile guidance. Tactics combine both.
What training pays off most?
High-alpha entry/exit, energy management after post-stall moves, and HMS cueing under high g.
Where does the Su-35 fit in a mixed fleet?
As an air-dominance spearhead with strong WVR credibility and solid BVR capability, complementing heavier strike platforms.
