General Information

F22: The Lockheed Martin F-22 raptor is an American single-seat, twin-engine, all-weather stealth tactical fighter aircraft. The aircraft first flew in 1997.

Su-57: The Sukhoi Su-57 is a twin engine stealth Russian multirole fighter
aircraft developed by Sukhoi. The aircraft first flew in 2010.

J-20: The Chengdu J-20 (a.k.a the mighty dragon) is a twinjet all-weather
stealth fighter aircraft developed by China’s Chengdu aerospace
corporation. The J-20 first flew in 2011.


F22: In 1981, the U.S Air force identified the need for a advanced tactical fighter aircraft. Code named “senior sky” the aircraft was suppose
to replace the f-15 eagle and the f-16 fighting falcon.

Su-57: In 2004, Sukhoi anticipated that the Su-57 could become the basis
for a family of combat aircrafts for the Russian aerospace forces,
similar to the Su-27 family. The development took place under the
program name megalopolis.

J-20: The aircraft emerged from the late 1990s J-XX program. The
aircraft went under several changes and it was the 3rd prototype
which was considered to be final

Design and Build

F22: It is a fifth-generation fighter aircraft, it is the first operational
aircraft to combine super cruise, supermaneuvrability, stealth and
sensor fusion in a single weapons format. It has clipped diamond like
delta wings. The raptor has 2 engines each of them having a
maximum thrust capacity in the 156kn class. Maximum speed
without external burners is Mach 1.8 and with afterburners Mach 2.
Titanium alloys and bismaleimide/epoxy composites comprise 42%
and 24% of the structural weight respectively. The aircraft also has
an excellent angle of attack.

Su57: It is a fifth-generation stealth fighter aircraft, the fighter
emphasizes supermaneuvrability in all aircraft axes, capacious
internal payload bays for multirole versatility, and advanced sensor
systems. It has a wide blended wing body, it has 2 engines and
reaches a maximum speed of Mach 2. The structural composition of
the aircraft is 40.5–44.5% Aluminum alloys and 18.6% titanium

J-20: The aircraft has a long body with a chiseled nose section and a
frameless canopy. Having a delta wing body with canard surface
provides it excellent supersonic performance. The maximum speed
of this aircraft is said to be Mach 1.8. the design also helps in
reducing supersonic drag without compromising the lift to drag

In conclusion, the Su-57, J-20, and F-22 represent the cutting edge of modern fighter aircraft technology, each with its own unique strengths and capabilities. The Su-57, developed by Russia, boasts impressive maneuverability, advanced avionics, and a sophisticated sensor suite, making it a formidable opponent in air-to-air combat scenarios. China’s J-20, with its sleek stealth design and long-range capabilities, emphasizes the importance of penetrating enemy airspace undetected and delivering precision strikes from afar. On the other hand, the F-22, a product of the United States, has set a standard for unmatched stealth performance, superior situational awareness, and unrivaled dogfighting capabilities, solidifying its reputation as the world’s most advanced and dominant fifth-generation fighter. Each aircraft brings a unique set of advantages to the skies, and the ongoing competition between them drives continuous innovation and advancement in the field of aerial warfare. As technology evolves and nations strive for air superiority, these remarkable aircraft will continue to shape the future of modern warfare and redefine the boundaries of aerial dominance.
