Stealth Fighter Showdown: F-22 Raptor vs. China’s J-20 (Who Wins?)

A U.S. Air Force F-22 Raptor from the 95th Fighter Squadron, Tyndall Air Force Base, Fla., moves into position behind a KC-135 Stratotanker from the 100th Air Refueling Wing, RAF Mildenhall Air Base, England, to conduct aerial refueling Sept. 4, 2015, over the Baltic Sea. The U.S. Air Force has deployed four F-22 Raptors, one C-17 Globemaster III, approximately 60 Airmen and associated equipment to Spangdahlem Air Base, Germany. While these aircraft and Airmen are in Europe, they will conduct air training with other Europe-based aircraft. (U.S. Air Force photo by Tech. Sgt. Jason Robertson/Released)

The U.S. Air Force remains the sole operator of the stealth Lockheed Martin F-22 Raptor, an aircraft widely regarded as the most dominant fighter in the world. It is especially respected for its dogfighting ability and air-to-air maneuverability attributes. Primarily designed as an air superiority fighter, it also offers ground attack, electronic warfare, and signals intelligence capabilities.

Ask many aviation experts, and they’ll be quick to tell you that the F-22 is unrivaled in the world. Of course, not everyone agrees with that assessment, notably those in China’s People’s Liberation Army Air Force (PLAAF), and instead touted the capabilities of its Chengdu J-20 “Mighty Dragon.”

It is true that the J-20, which came about from Beijing’s J-XX program in the 1990s and only made its maiden flight on January 11, 2011, is a newer platform. In fact, it only began test flights a year before production ended on the F-22 Raptor. As the world’s third operational fifth-generation stealth fighter, after the F-22 and the Lockheed Martin F-35 Lightning II, the J-20 had the advantage of building on what worked.

It also likely didn’t hurt that China likely stole U.S. technology to develop the J-20. Yet, there is a problem with simply copying (stealing), and as has been seen in almost everything that comes out of China the result is an inferior product. Reverse engineering doesn’t result in an improvement. This is true whether it is golf clubs, smartphones, athlete shoes, or aircraft carriers.

The J-20 thus lacks the capabilities of the F-22, and despite the boasting from Beijing, it was also simply meant to be a starting point to serve as a stepping stone for more advanced aircraft to come. That’s the Chinese way of innovating. Copy first, improve after.

Comparing the Designs

The J-20 and F-22 do share many similarities. The J-20 fuselage appears to resemble that of an F-22 with two engine exhausts and a blended, curved, or rounded main body exterior. At 69 feet, seven inches, the Chinese J-20 is slightly larger than an F-22, which is 62 feet, one inch in length. However, the wing configurations of a J-20 and F-22 are decidedly different, with the J-20 having a slightly smaller wingspan and total wing area.

Both combat aircraft utilize internal weapons bays, allowing them to maintain higher performance than fourth-generation combat fighters. The J-20 is also a lighter aircraft but has a larger internal fuel capacity.

While the exact capabilities of the Chengdu J-20 haven’t been largely disclosed, the Chinese have struggled to provide an adequate powerplant for the fighter. It was initially powered by the Russian-made Al-31F engines, as well as the indigenously-produced WS-10B. Each of those engines was designed for less advanced aircraft. Moreover, efforts to produce a new engine, the WS-15, also came up short when it failed its final evaluation in 2019.

As a result, engineers have been fitting the aircraft with the WS-10C, an upgraded version of the original WS-10. With the WS-15 engine, the J-20 is believed to have a range of 1,200 miles (2,000 km) and a servicing ceiling of 66,000 feet (20,000 meters), and a maximum speed of Mach 2.55 or higher.

The first Raptor assigned to the Wing arrived Jan. 7, 2005. This aircraft was allocated as a trainer, and was docked in a hanger for maintenance personnel to familiarize themselves with its complex systems. The second Raptor, designated for flying operations, arrived Jan. 18, 2005. On Dec. 15, 2005, Air Combat Command commander, along with the 1 FW commander, announced the 27th Fighter Squadron as fully operational capable to fly, fight and win with the F-22.

Powered by two Pratt & Whitney turbofan engines, the F-22 Raptor is capable of reaching speeds of Mach 2 (1,534 mph/2,469 kph). It has a ceiling of 50,000 feet (15 kilometers) and a range of 1,841 miles (2,962 km) without refueling. Unlike the J-20, however, the F-22 is able to reach supercruise speed and more importantly sustain it without the need of afterburners.

It is possible that the J-20 will be improved – including finally being equipped with an engine worthy of the airframe – yet for now, the Mighty Dragon seems to be a mere facsimile of the Raptor. Both are likely capable aircraft, but the Raptor’s claws and better maneuverability could give it an advantage in a match-up with the Mighty Dragon.

    And the other piece of the puzzle is that the chicoms have never been pressure tested as it were.

    What a stupid comment to call J-20 a copy of F-22 when they employ completely different aerodynamic configurations. When you copy, you have to go the full 9 yards, not bits and pieces as minor changes would have ruined the flight characteristics. Such throw away line of Chinese copying F-22 shows the author has a complete lack of understanding in aeronautical engineering

      There is no doubt the Chinese stole and copied the TECHNOLOGIES applied to the F-22. That would apply to material apps and construction techniques, along with stealth and avionic tech.
      However, they couldn’t get their theivin’ paws on the propulsion tech- reliance was first on antiquated Russian tech, now that useless, inefficient Chicom power.

    After winning the dogfight vs Raptor & J-20, J-20 (WS-10G engines) should be called as MIGHTY DRAGON.
