The F-22’s supercruise allows it to maintain Mach 1.5 without afterburners, optimizing range, stealth, and tactical effectiveness. Find out why this changes everything.
The concept of supercruise in aviation technology
Supercruise is an aircraft’s ability to maintain supersonic flight without afterburners. Unlike most fighters, which can only exceed Mach 1 by activating their afterburners, the F-22 Raptor can supercruise beyond Mach 1.5 in combat configuration. This feature is a true technical and tactical revolution in air superiority aviation.
The mechanics behind the F-22’s supercruise capability
The supercruise technology on the F-22 is based on the synergy between several elements:
- Pratt & Whitney F119 engines, designed to provide high thrust (≈ 15,560 kN) while allowing sustained flight at Mach 1.8 without afterburners.
- A highly optimized aerodynamic structure, with air intakes, tapered shapes, and discreetly indented wings—everything is designed to reduce drag and promote radar stealth.
- A stealthy design, including internal weapon bays, which minimizes external drag and increases maneuverability and stealth even at high speeds.
Why supercruise is a decisive tactical advantage
1. Optimization of the range of a fighter jet in supercruise
Maintaining prolonged supersonic speed without afterburners translates into massive fuel savings. Even though flying at Mach 1.5 consumes more fuel than subsonic flight, the comparative savings from afterburners are significant. According to some calculations, a 100 nautical mile (≈ 190 km) stretch in supercruise would reduce the range from approximately 160 nmi to 120 nmi (≈ 830 km instead of 1,110 km) over the course of a mission—a modest reduction compared to the overwhelming impact of afterburner use.
2. Accelerated deployment speed
The F-22 can reach Mach 1.5 without afterburners, giving it a fighter jet deployment speed far superior to that of conventional aircraft (Mach 0.8–0.9 with load). This allows it to intercept more quickly or reposition with agility, reducing downtime and offering unmatched strategic responsiveness.
3. Enhanced aerial stealth
The use of afterburners generates a marked infrared signature and a plume that is detectable by radar. Supercruise and aerial stealth are mutually reinforcing: without afterburners, the aircraft becomes less visible across multiple spectra. This maximizes surprise and aerial superiority from the moment of engagement.
4. Air superiority and increased operational effectiveness
Thanks to supercruise, the F-22 has an effective internal weapons and sensor payload without compromising aerodynamic performance. This configuration allows it to be more tactically and operationally effective against modern threats. It combines stealth, supercruise, and integrated avionics to reduce enemy engagement windows and increase lethality.
Illustrated by specific data
- Supercruise speed: Mach 1.5 in combat configuration, with peaks of up to Mach 1.8 without afterburners.
- Internal fuel capacity: approximately 8,160 kg (18,000 lb), with additional external tanks available for transit missions.
- Ferry range (with external tanks): over 2,960 km (1,600 nautical miles).
- Structural materials: 42% titanium alloys, 24% bismaleimide/epoxy composites, to withstand the heat and stresses of supersonic flight.
The difference between supercruise and afterburners
Afterburners inject fuel into the exhaust gases to produce extra thrust, but at the cost of extremely high fuel consumption and a noticeable heat signature. The supercruise capability of a fighter jet such as the F-22 allows it to maintain high speed using the engines at full normal power, without resorting to this energy-intensive mode. This improves fuel management during supercruise, stealth, and tactical range, while maintaining advanced fighter aircraft maneuverability thanks to thrust vectoring.
The impact on the overall performance of the F-22
The supercruise of the F-22 is not just a marketing ploy. It illustrates the difference between supercruise and afterburner, based on supercruise technology, which is accompanied by more efficient fuel management during supercruise. The aircraft can benefit from:
- Extended supersonic flight without dramatic fuel consumption.
- Optimized range for a fighter jet in supercruise.
- Significantly increased deployment speed for a fighter jet.
- A tactical advantage of supercruise proven in simulations and combat.
- Operational efficiency, as aircraft can cover greater distances, maintain superiority for longer, and intervene more quickly.
The role of supercruise in modern air combat
In air combat, an F-22 in supercruise can:
- Intercept an adversary before they become threatening.
- Reposition quickly to engage or disengage at will.
- Minimize radar or infrared detection windows.
- Employ its long-range missiles more effectively, thanks to extended supersonic flight without afterburners, which offers a strategic advantage.
These capabilities make the F-22 a pillar of modern air superiority, with a unique combination of extended supersonic speed, stealth, and extreme maneuverability.
Supercruise remains an area of ongoing innovation. Aircraft such as the Eurofighter Typhoon and the Rafale can reach Mach 1.2–1.4 without afterburners, but the F-22 remains the benchmark in supercruise. In the future, engines such as the izdeliye 30 for the Su-57 aim to close this gap.
