The F-35 Lightning II and the F-22 Raptor: A Comprehensive Comparison
The F-35 Lightning II and the F-22 Raptor are two of the most advanced fighter jets in the world, representing the fifth generation of military aviation. Both aircraft are designed to dominate the skies and provide a significant advantage on the battlefield. However, they have distinct differences in design, capabilities, and purpose. In this article, we will delve into the details of these two aircraft and compare their features, performance, and operational characteristics.
Design and Development
The F-22 Raptor is a fifth-generation, single-seat, twin-engine supermaneuverable fighter aircraft developed by Lockheed Martin. The F-22 is a multi-role fighter designed to perform air-to-air and air-to-ground missions with advanced avionics and stealth capabilities. The first F-22 was delivered to the US Air Force in 2005, and it has been in service since 2007.
The F-35 Lightning II is also a fifth-generation, multi-role fighter developed by Lockheed Martin. The F-35 is designed to perform air-to-air, air-to-ground, and reconnaissance missions with advanced avionics and stealth capabilities. The F-35 has three variants: the F-35A (Conventional Takeoff and Landing), the F-35B (Short Takeoff/Vertical Landing), and the F-35C (Carrier Variant). The first F-35 was delivered to the US Air Force in 2011, and it has been in service since 2015.
Stealth Capabilities
Both the F-22 and F-35 are designed with stealth capabilities to reduce their radar cross-section (RCS) and evade enemy detection. However, the F-22 has a more advanced stealth design, with a reduced RCS of approximately 0.0001 square meters. The F-35 has a slightly higher RCS, approximately 0.001 square meters.

|---|---|---|
| Top Speed | Mach 2.25 (1,800 mph) | Mach 1.6 (1,200 mph) |
| Thrust-to-Weight Ratio | 1.09 | 0.97 (F-35A), 0.93 (F-35B/C) |
| Service Ceiling | 65,000 ft (19,685 m) | 50,000 ft (15,240 m) |
| Range | 1,600 nmi (2,960 km) | 1,200 nmi (2,222 km) |
Avionics and Sensor Systems
Both the F-22 and F-35 have advanced avionics and sensor systems, including radar, electronic warfare, and communication systems. The F-22 has the AN/APG-77 Active Electronically Scanned Array (AESA) radar, while the F-35 has the AN/APG-81 AESA radar.
Avionics Comparison:
| Feature | F-22 Raptor | F-35 Lightning II |
|---|---|---|
| Radar System | AN/APG-77 AESA | AN/APG-81 AESA |
| Electronic Warfare System | AN/ALR-94 | AN/ASQ-239 |
| Communication System | AN/ARC-231 | AN/ARC-231 |
Operational Characteristics
The F-22 and F-35 have different operational characteristics, reflecting their design purposes. The F-22 is primarily designed for air-to-air combat, while the F-35 is designed for multi-role operations, including air-to-air, air-to-ground, and reconnaissance missions.
Operational Comparison:
| Feature | F-22 Raptor | F-35 Lightning II |
|---|---|---|
| Primary Mission | Air-to-air combat | Multi-role operations |
| Secondary Mission | Air-to-ground | Air-to-air, reconnaissance |
| Takeoff and Landing | Conventional | Conventional (F-35A), STOVL (F-35B), CATOBAR (F-35C) |
🚨 Note: The F-22 is not designed for air-to-ground missions, while the F-35 has a more flexible design for various missions.
Conclusion
In conclusion, the F-22 Raptor and the F-35 Lightning II are two of the most advanced fighter jets in the world, with distinct differences in design, capabilities, and purpose. The F-22 is a highly maneuverable air-to-air fighter with advanced stealth capabilities, while the F-35 is a multi-role fighter with advanced avionics and sensor systems.
