Russia Sukhoi
Su-35S
Heavily upgraded single-seat derivative of the Su-27 Flanker family, featuring thrust-vectoring engines, an AESA-hybrid radar and extreme aerodynamic agility for within-visual-range combat. Serves as Russia's primary 4++ generation air-superiority fighter pending wider Su-57 fielding.

Procurement snapshot
Availability & export
Russian state channel
Rosoboronexport monopoly; Western sanctions exposure and payment/logistics risk for many buyers.
Channel: Rosoboronexport (state)
Fielded & proven
Limited · 3 operators
In service since 2014. Status: active · ~140 built.
Lifecycle cost (est.)
$163M – $228M
Acquisition is only ~30% of lifecycle cost — operating & support dominate over ~30 yrs. Rough 2.5–3.5× the unit price.
Interoperability
No standardised NATO calibre / datalink detected in public specs.
Derived guidance from public data — export regime by country of origin, lifecycle from the GAO ~30% acquisition rule. Verify eligibility, pricing and offsets with the manufacturer and your acquisition authority.
Full specifications
Performance
Speed, range, altitude and engagement capability.
- Max speed
Maximum level speed. For aircraft this is at optimal altitude; for ground vehicles, top road speed. Higher means faster response and better kinematic performance.
- 2,500 km/h Stronger than 89% of fighters
- Max speed (Mach)
Maximum speed as a multiple of the speed of sound. Mach 2+ is typical for air-superiority fighters.
- 2.25 Mach Stronger than 80% of fighters
- Range
Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence.
- 3,600 km Stronger than 72% of fighters
- Combat radius
Distance an aircraft can fly, complete its mission and return without refueling. Roughly a third of ferry range.
- 1,600 km Top 8% of fighters
- Service ceiling
Maximum operating altitude. Higher gives energy advantage and sensor horizon.
- 18,000 m Stronger than 72% of fighters
- Rate of climb
How fast the aircraft gains altitude. Higher means better energy recovery in combat.
- 280 m/s Stronger than 56% of fighters
- Thrust-to-weight
Engine thrust divided by loaded weight. Above 1.0 the aircraft can accelerate going straight up.
- 1.13 Top 5% of fighters
Firepower
Armament, payload and guidance.
- Main armament
Primary weapon: main gun, cannon or missile type.
- 30 mm GSh-30-1 cannon
- Hardpoints
External stations for weapons and pods. More means bigger and more flexible loadouts.
- 12 Stronger than 86% of fighters
- Weapons payload
Maximum ordnance weight the platform can carry. Higher means more strike capacity per sortie.
- 8,000 kg Stronger than 63% of fighters
Protection
Armor, countermeasures and survivability.
- Countermeasures
Self-protection: chaff, flares, DIRCM, towed decoys, smoke dischargers, jammers.
- Khibiny electronic warfare pods, chaff, flares
Physical
Dimensions, weight and crew.
- Length
Overall length including gun/probe where applicable.
- 21.9 m
- Wingspan
Wingtip-to-wingtip span.
- 15.3 m
- Height
Overall height. Lower profile is harder to spot and hit for ground vehicles.
- 5.9 m
- Empty weight
Weight without fuel, ammunition or crew.
- 19,000 kg
- Combat weight
Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor.
- 34,500 kg
- Crew
Personnel required to operate. Fewer reduces exposure; autoloaders trade a loader for mechanical complexity.
- 1
Propulsion
Engine, power and fuel.
- Engine
Powerplant model and type.
- 2x Saturn AL-41F1S thrust-vectoring afterburning turbofans
- Engines
Number of engines. Twin-engine gives redundancy at higher cost.
- 2
- Thrust
Total engine thrust (with afterburner where applicable).
- 142 kN Stronger than 85% of fighters
- Fuel capacity
Internal fuel volume.
- 11,500 L
- Propulsion type
Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet…
- Turbofan
Sensors & avionics
Radar, sensor suite and datalinks.
- Radar
Primary radar. AESA (active electronically scanned array) is the current state of the art.
- Irbis-E passive electronically scanned array (PESA)
- Sensors
IRST, EO/IR turrets, laser designators, sniper pods, thermal sights.
- OLS-35 infrared search and track, Khibiny EW suite
Program
Cost, production scale and operators.
- Unit cost
Approximate flyaway/unit cost where public. Defense pricing varies hugely by contract, offsets and configuration. Lower is cheaper.
- $65,000,000 Stronger than 42% of fighters
- Units built
Total production run. Higher means proven manufacturing, mature logistics and spares availability.
- 140 Stronger than 34% of fighters
- Operator countries
Number of countries operating the system. More operators means broader support ecosystem.
- 3 Stronger than 61% of fighters
