Intro
Uncover the differences between the J-35 and F-35 fighter jets. Discover the 5 key distinctions in design, capabilities, and performance that set these two advanced aircraft apart. Learn about their unique features, including stealth technology, propulsion systems, and combat roles, to understand which jet reigns supreme in the skies.
The world of military aviation is filled with advanced aircraft, each designed to perform specific tasks and protect national interests. Two of the most notable fighter jets in the world today are the Saab JAS 39 Gripen, commonly referred to as the J-35, and the Lockheed Martin F-35 Lightning II. Both aircraft are multi-role fighters, capable of air-to-air combat, air-to-ground strikes, and reconnaissance. However, despite their similarities, the J-35 and F-35 have several key differences that set them apart.
Design and Development
The J-35 and F-35 have distinct design philosophies. The J-35, developed by Saab in Sweden, is a smaller, lighter aircraft designed for agility and maneuverability. In contrast, the F-35, developed by Lockheed Martin in the United States, is a larger, more complex aircraft designed to be a multi-role fighter with advanced stealth capabilities.
Size and Weight
The F-35 is significantly larger and heavier than the J-35. The F-35 has a length of 51.4 feet (15.67 meters) and a wingspan of 35 feet (10.67 meters), while the J-35 has a length of 46.3 feet (14.1 meters) and a wingspan of 27.6 feet (8.4 meters). The F-35 also has a maximum takeoff weight of 70,000 pounds (31,751 kilograms), compared to the J-35's maximum takeoff weight of 31,000 pounds (14,061 kilograms).
Engine and Propulsion
The J-35 and F-35 have different engine configurations. The J-35 is powered by a single Volvo Aero (now GKN Aerospace) RM12 turbofan engine, which produces 22,000 pounds of thrust. In contrast, the F-35 is powered by a single Pratt & Whitney F135 turbofan engine, which produces 22,000 pounds of thrust in the F-35A and 40,000 pounds of thrust in the F-35B and F-35C.
Thrust-to-Weight Ratio
The J-35 has a higher thrust-to-weight ratio than the F-35, which allows it to accelerate faster and climb more steeply. The J-35's thrust-to-weight ratio is 1.28, while the F-35's thrust-to-weight ratio is 0.93.
Avionics and Electronics
The J-35 and F-35 have advanced avionics and electronics, but with different configurations. The J-35 has a Saab Avitronics (now Saab Defense and Security) avionics system, which includes a digital fly-by-wire flight control system and a pulse-doppler radar. In contrast, the F-35 has a Northrop Grumman (now Northrop Grumman Innovation Systems) avionics system, which includes a digital fly-by-wire flight control system and an active electronically scanned array (AESA) radar.
Radar and Sensors
The F-35 has a more advanced radar and sensor system than the J-35. The F-35's AESA radar provides improved range, resolution, and targeting capabilities, while the J-35's pulse-doppler radar has more limited capabilities.
Stealth Capabilities
The F-35 has advanced stealth capabilities, designed to reduce its radar cross-section and make it more difficult to detect. The J-35 does not have the same level of stealth capabilities as the F-35.
Radar Absorbent Materials
The F-35 is coated with radar-absorbent materials (RAMs) to reduce its radar cross-section. The J-35 does not have RAMs, which makes it more visible to radar.
Operational Costs
The J-35 and F-35 have different operational costs. The J-35 is generally considered to be less expensive to operate than the F-35.
Life Cycle Costs
The F-35 has higher life cycle costs than the J-35, primarily due to its more complex design and advanced technologies. The F-35's life cycle costs are estimated to be around $1.5 trillion over its lifespan, while the J-35's life cycle costs are estimated to be around $10 billion.
