Learn about the evolution of air superiority and which aircraft reigns supreme in the skies.
The F-15 Eagle and the F-22 Raptor are two of the most advanced fighter jets in the world, with a long history of development and deployment by the United States Air Force. While both aircraft are designed for air superiority and multi-role capabilities, there are significant differences between them. In this article, we will explore the 5 key differences between the F-15 and the F-22, highlighting their design, performance, and operational characteristics.
1. Design and Aerodynamics
The F-15 and F-22 have distinct designs, reflecting their different development periods and design philosophies. The F-15, first flown in 1972, has a conventional, twin-engine design with a rectangular fuselage and a distinctive twin-fin tail. In contrast, the F-22, first flown in 1997, features a more advanced, stealthy design with a curved, faceted fuselage and a V-tail. The F-22's design incorporates advanced materials and shaping to minimize radar cross-section, making it more difficult to detect.
Design Evolution
The F-15's design has undergone several upgrades and modifications over the years, including the addition of advanced avionics, engines, and radar systems. The F-22, on the other hand, was designed from the outset with advanced stealth capabilities and has undergone fewer significant design changes.
2. Propulsion and Performance
The F-15 and F-22 have different propulsion systems, which impact their performance and capabilities. The F-15 is powered by two Pratt & Whitney F100-PW-229 engines, producing a combined 28,000 pounds of thrust. The F-22, on the other hand, is powered by two Pratt & Whitney F119-PW-100 engines, producing a combined 35,000 pounds of thrust.
Thrust-to-Weight Ratio
The F-22's more powerful engines give it a higher thrust-to-weight ratio, allowing it to accelerate faster and climb more steeply than the F-15. The F-22 can also maintain supersonic speeds without afterburners, reducing its radar signature and improving fuel efficiency.
3. Radar and Avionics
Both the F-15 and F-22 have advanced radar and avionics systems, but the F-22's systems are more sophisticated and integrated. The F-22's AN/APG-77 radar system is a highly advanced, phased-array radar that provides unparalleled air-to-air and air-to-ground capabilities. The F-15's AN/APG-63(V)3 radar system is also highly capable, but less advanced than the F-22's system.
Network-Centric Warfare
The F-22's avionics system is designed to support network-centric warfare, allowing it to share data and coordinate with other aircraft and ground systems in real-time. The F-15's avionics system is also network-capable, but less advanced than the F-22's system.
4. Stealth and Survivability
The F-22's stealth design and advanced materials make it significantly more difficult to detect and engage than the F-15. The F-22's radar cross-section is estimated to be 1/100th that of the F-15, making it a much harder target to detect and track.
Survivability Features
The F-22 has several survivability features, including its stealth design, advanced electronic countermeasures, and a robust self-protection system. The F-15 also has self-protection systems, but they are less advanced than the F-22's systems.
5. Operational Experience and Costs
The F-15 has a long history of operational service, with over 30 years of combat experience in various conflicts. The F-22, on the other hand, has seen limited combat service, but has demonstrated its effectiveness in several exercises and deployments.
Operating Costs
The F-15 is generally considered to be less expensive to operate than the F-22, due to its lower purchase price and lower maintenance requirements. However, the F-22's advanced capabilities and lower radar signature make it a more effective aircraft in many scenarios.

What is the primary difference between the F-15 and F-22?
+The primary difference between the F-15 and F-22 is their design philosophy and capabilities. The F-15 is a multi-role fighter with a focus on air-to-air combat, while the F-22 is a fifth-generation stealth fighter with advanced air-to-air and air-to-ground capabilities.
Which aircraft has better stealth capabilities?
+The F-22 has significantly better stealth capabilities than the F-15, due to its advanced design and materials. The F-22's radar cross-section is estimated to be 1/100th that of the F-15.
Which aircraft is more expensive to operate?
+The F-22 is generally considered to be more expensive to operate than the F-15, due to its advanced capabilities and higher maintenance requirements.
We hope this article has provided a comprehensive overview of the key differences between the F-15 and F-22. Both aircraft are highly capable and have played important roles in the US Air Force's fleet, but they have distinct design philosophies and capabilities that set them apart.
