Russia In development Sukhoi
Su-75 Checkmate
Single-engine, single-seat lightweight stealth fighter unveiled by Rostec/Sukhoi at MAKS 2021 as a lower-cost, export-oriented complement to the Su-57. Caveat: performance figures and export interest are Russian state/manufacturer claims and not independently verified; the program has slipped its first-flight target three times (2023 to 2024 to 2025 to a planned 2026), lost UAE co-funding, and faces sanctions-driven supply constraints on semiconductors and machine tools, leading Western analysts (including RAND) to question whether it will fly on the stated timeline.

Lifecycle cost (est.)
$69M – $96M
Acquisition is only ~30% of lifecycle cost, operating & support dominate over ~30 yrs. Rough 2.5–3.5× the unit price. How we estimate this →
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 (Mach) Maximum speed as a multiple of the speed of sound. Mach 2+ is typical for air-superiority fighters. | 1.8 Mach |
|---|---|
| Range Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence. | 2,900 km |
| Service ceiling Maximum operating altitude. Higher gives energy advantage and sensor horizon. | 16,500 m |
| Thrust-to-weight Engine thrust divided by loaded weight. Above 1.0 the aircraft can accelerate going straight up. On a standalone engine record, this is the engine's own thrust divided by its dry weight, the standard figure of merit for jet engines. | 1 |
Firepower
Armament, payload and guidance.
| Hardpoints External stations for weapons and pods. More means bigger and more flexible loadouts. | 11 |
|---|---|
| Weapons payload Maximum ordnance weight the platform can carry. Higher means more strike capacity per sortie. | 7,400 kg |
Physical
Dimensions, weight and crew.
| Length Overall length including gun/probe where applicable. | 17.7 m |
|---|---|
| Wingspan Wingtip-to-wingtip span. | 11.8 m |
| Height Overall height. Lower profile is harder to spot and hit for ground vehicles. | 4 m |
| Combat weight Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor. | 26,000 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. | 1x NPO Saturn AL-51F-1 afterburning turbofan |
|---|---|
| Engines Number of engines. Twin-engine gives redundancy at higher cost. | 1 |
| Thrust Total engine thrust (with afterburner where applicable). | 162 kN |
| Propulsion type Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet… | Turbofan, afterburning |
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. | $27,500,000 |
|---|---|
| Units built Total production run. Higher means proven manufacturing, mature logistics and spares availability. | 0 |
| Operator countries Number of countries operating the system. More operators means broader support ecosystem. | 0 |
