The ongoing evolution of military aviation has placed the Lockheed Martin F-22 Raptor and the Sukhoi Su-57 Felon at the forefront of fifth-generation fighter jets as of 2025. While the F-22 has been operational since December 15, 2005, the Su-57, which entered service in December 2020, represents Russia’s latest advancements in aerial combat technology. Both aircraft are designed for stealth and multirole operations, but they exhibit distinct capabilities and operational philosophies that reflect their respective military objectives.
The F-22 Raptor is often hailed as the stealthiest fighter jet available today. Its advanced design allows the United States Air Force (USAF) to maintain air dominance. With a radar cross-section of just 0.0001 m², the F-22 is nearly invisible to enemy radar systems. This aircraft, powered by two Pratt & Whitney F119-PW-100 engines, achieves a maximum speed exceeding Mach 2 and can supercruise at Mach 1.82 without afterburners, making it a formidable adversary in aerial engagements.
In contrast, the Su-57 Felon, equipped with either Saturn AL-41F1 or Izdeliye-30 engines, also reaches speeds above Mach 2, but emphasizes versatility and adaptability. The Su-57 excels in a range of roles, from air superiority to ground attack, accommodating various weaponry in its internal bays. This flexibility is crucial for the Russian Aerospace Forces (VKS), especially given the current geopolitical climate.
Comparative Analysis of Capabilities
Both aircraft feature advanced avionics, but their designs reflect different strategic priorities. The F-22 prioritizes stealth and first-strike capabilities, while the Su-57 emphasizes multirole versatility. The Su-57’s radar cross-section measures approximately 0.5 m², reflecting a design that balances stealth with operational effectiveness.
The F-22’s AN/APG-77 radar system integrates seamlessly with US military networks, providing superior situational awareness and targeting capabilities. This integration allows the F-22 to adhere to its “first look, first shot, first kill” doctrine, ensuring effectiveness in combat scenarios.
Conversely, the Su-57’s N036 Byelka radar system enhances its target acquisition and tracking capabilities, although it does not match the F-22’s stealth profile. The Su-57’s versatility in armament allows it to carry a diverse arsenal, including air-to-air missiles and precision-guided munitions for ground attacks, making it a valuable asset for a range of missions.
Cost and Operational Efficiency
Economic considerations play a significant role in the operational viability of these fighters. The F-22 Raptor is the most expensive fighter jet in production today, with a unit cost exceeding $140 million. When factoring in development and lifecycle costs, the total can reach up to $350 million per aircraft. The USAF’s initial production goal of 750 units was drastically reduced to just 195 due to these soaring costs and the decision to restrict foreign sales.
In comparison, the Su-57 offers a more affordable option for the Russian military, with an estimated unit cost of around $50 million. This lower price point is crucial for Russia, particularly as it faces economic sanctions and production challenges. Reports suggest that the Su-57 has an operational cost of approximately $24,000 per flight hour, in stark contrast to the F-22’s estimated costs that can exceed $80,000 per hour.
Despite the Su-57’s lower production numbers—around 40 units as of November 2025—the aircraft’s operational costs make it an appealing option for Russia if it can overcome production hurdles exacerbated by international sanctions.
Both aircraft face challenges in production scalability. The F-22’s production halted over a decade ago, while the Su-57 remains in limited production due to technical complications and material shortages. The future of both programs will depend on their ability to adapt to the evolving demands of aerial warfare and production capabilities.
In conclusion, while the F-22 Raptor continues to set the standard for stealth and air dominance, the Su-57 Felon offers a cost-effective alternative with a focus on versatility. The ongoing development of these jets illustrates the dynamic landscape of modern military aviation, where technological advancements and economic constraints will dictate future capabilities and operational strategies.
