introduction of f-15 Eagle
For over five decades, the F-15 Eagle has been the gold standard for air superiority. With an unmatched combat record of 104 victories and zero losses, it remains the only fighter in history to never be shot down by an enemy aircraft in air-to-air combat. From the Cold War era F-15A to the 21st-century F-15EX Eagle II, the platform has evolved from a pure dogfighter into a multi-role digital powerhouse.
1. Performance & Propulsion: The Physics of Power
The F-15’s "secret sauce" is its High Thrust-to-Weight Ratio (greater than 1:1), which allows it to accelerate even while in a vertical climb.

F-15EX vs Su-35 Comparison Table
| Feature | Boeing F-15EX (America) | Sukhoi Su-35 (Russia) |
|---|---|---|
| Role | Multirole / Air Superiority Fighter | Air Superiority Fighter |
| Estimated Cost (per flight hour) | Approximately US$27,000–32,000 | Approximately US$15,000–23,000 |
| Estimated Unit Cost | Approximately US$90–110 million | Approximately US$85–100 million |
| Maximum Speed | Mach 2.5 (around 2,656 km/h) – Faster | Mach 2.25 (around 2,400 km/h) |
| Maximum Payload | Approximately 13,300 kg (23 hardpoints) – Significantly higher | Approximately 8,000 kg (12 hardpoints) |
| Primary BVR Missile | AIM-120D AMRAAM (160+ km) | R-37M (up to 300 km) / R-77-1 |
| Radar System | AN/APG-82 AESA (Active Electronically Scanned Array) | Irbis-E PESA (Passive Electronically Scanned Array) |
| Ferry Range | Approximately 4,800 km (with conformal fuel tanks) | Approximately 4,500 km (with external fuel tanks) |
Combat Capability Differences
1. Exceptional Payload Capacity
The F-15EX is often described as a flying "missile truck" due to its extraordinary payload capacity. It can carry up to 13,300 kg of weapons across 23 hardpoints, allowing it to deploy a much larger mix of air-to-air missiles, guided bombs, and stand-off weapons than the Su-35, which is limited to 12 hardpoints and approximately 8,000 kg of payload.
2. Dogfighting and Maneuverability
While the F-15EX is a highly capable and agile fighter, the Su-35 is widely regarded as one of the world's most maneuverable combat aircraft. Thanks to its 3D thrust-vectoring engines, the Su-35 can perform extreme post-stall maneuvers, including the famous Pugachev's Cobra, giving it a distinct advantage in close-range dogfights.
3. Radar and Electronic Warfare
The F-15EX holds a clear technological advantage in avionics. It features the AN/APG-82 AESA radar together with the advanced EPAWSS (Eagle Passive/Active Warning and Survivability System), providing outstanding electronic warfare, radar jamming, threat detection, and missile survivability. In comparison, the Su-35 relies on the powerful Irbis-E PESA radar, which offers excellent detection range but is generally considered less resistant to modern electronic countermeasures than an AESA radar.
4. Beyond-Visual-Range (BVR) Combat
The F-15EX primarily employs the AIM-120D AMRAAM, an advanced BVR missile with an estimated engagement range of 160+ km and a proven track record for accuracy and reliability. The Su-35, however, can carry the R-37M, a very long-range air-to-air missile with an estimated range of up to 300 km against suitable targets, giving it a significant reach advantage in certain engagement scenarios. However, actual combat effectiveness depends on factors such as radar performance, target detection, electronic warfare, and pilot proficiency—not missile range alone.
Conclusion
The F-15 Eagle has successfully bridged the gap between the Cold War and the digital age. While stealth fighters like the F-22 and F-35 hide from the enemy, the F-15EX is built to stay in the fight longer, carry more weapons, and dominate through sheer power and advanced electronics.
