Intro
Discover the ultimate showdown between two iconic fighter jets: the F-15 Eagle and the Su-27 Flanker. Learn about the 5 key differences between these air superiority heavyweights, including design, performance, avionics, armament, and operational history. Get a detailed comparison of these legendary jets and their unique characteristics.
The F-15 Eagle and the Su-27 Flanker are two of the most iconic and technologically advanced fighter jets in the world. Both aircraft have been in service for decades and have undergone numerous upgrades and modifications to stay relevant in the ever-evolving landscape of modern air warfare. While both planes are highly capable and have their own strengths and weaknesses, there are several key differences between them.
Aerodynamic Design
One of the most noticeable differences between the F-15 and the Su-27 is their aerodynamic design. The F-15 has a distinctive twin-tail configuration, with two vertical stabilizers and two horizontal stabilizers. This design provides exceptional stability and maneuverability, particularly at high speeds. In contrast, the Su-27 has a single vertical stabilizer and a pair of horizontal stabilizers, which are canted outward at an angle of 30 degrees. This design allows the Su-27 to maintain stability at high angles of attack and provides exceptional maneuverability at low speeds.
Propulsion Systems
The F-15 is powered by two Pratt & Whitney F100-PW-229 turbofan engines, which produce a combined 46,000 pounds of thrust. The Su-27, on the other hand, is powered by two Saturn AL-31F turbofan engines, which produce a combined 47,000 pounds of thrust. While both engines are highly efficient and reliable, the AL-31F has a slightly higher thrust-to-weight ratio than the F100-PW-229.
Avionics and Electronics
The F-15 has a highly advanced avionics system, featuring a Hughes AN/APG-70 pulse-doppler radar and a highly integrated electronic warfare system. The Su-27 also has a highly advanced avionics system, featuring a N001VE Pulse-Doppler radar and a comprehensive electronic warfare system. However, the Su-27's avionics system is more modular and easier to upgrade than the F-15's.
Armament and Payload
The F-15 has a range of air-to-air and air-to-ground munitions, including the AIM-120 AMRAAM, AIM-7 Sparrow, and AGM-84 Harpoon missiles. The Su-27 also has a range of air-to-air and air-to-ground munitions, including the R-27 Alamo, R-77 Adder, and Kh-31P missiles. However, the Su-27 has a higher payload capacity than the F-15 and can carry a wider range of munitions.
Operational History and Upgrades
The F-15 has a longer operational history than the Su-27, having first entered service in 1974. The Su-27 first entered service in 1984, but has undergone more extensive upgrades and modernizations over the years. Both aircraft have been upgraded with advanced avionics, new propulsion systems, and improved armament and payload capabilities.

FAQs
What is the top speed of the F-15?
+The top speed of the F-15 is approximately Mach 2.5 (around 1,800 mph or 2,900 km/h).
What is the range of the Su-27?
+The range of the Su-27 is approximately 2,500 miles (4,000 km), although this can be extended with in-flight refueling.
Which aircraft has a higher payload capacity?
+The Su-27 has a higher payload capacity than the F-15, with a maximum payload of around 22,000 pounds (10,000 kg) compared to the F-15's 16,000 pounds (7,300 kg).
In conclusion, the F-15 and Su-27 are both highly advanced fighter jets with their own unique strengths and weaknesses. While the F-15 has a longer operational history and a more advanced avionics system, the Su-27 has a higher payload capacity and a more modular design. Ultimately, the choice between these two aircraft will depend on the specific needs and requirements of the military or air force.
