Fourth generation fighters are still widely produced around the world and are often divided into sub-generations such as 4, 4+ and 4++. Improved versions of the fourth generation are often equipped with some features of fifth generation aircraft.

In 2005, the United States became the first country to field a fifth-generation fighter with the F-22 Raptor. Compared to previous generations of aircraft, the F-22 stands out thanks to its outstanding technological improvements.

As the first representative of the 5th generation, the most important difference between the F-22 and 4th generation aircraft is stealth technology, which is integrated right from the design stage instead of focusing only on aerodynamics and flight performance.

However, stealth is not the only thing that makes the F-22 special. The aircraft also possesses a number of core 5th generation features, including a highly integrated computer system that can connect and interact with other network platforms.

With its superior performance and multi-mission capability, the F-22 provides a significantly higher level of situational awareness than previous generation fighters.

The F-22 is also capable of supersonic flight without using boost combustion, allowing it to maintain high speeds without rapidly burning fuel.

For an interceptor like the F-22, this capability allows it to approach its target at extremely high speeds while still maintaining enough fuel to engage.

Meanwhile, the F-16 Fighting Falcon – the US Air Force's fourth-generation mainstay fighter – can run out of fuel in just a few minutes if using turbo-burn mode.

Currently, there are three lines of fifth-generation fighter aircraft in operation in the world: the US F-22 and F-35, China's J-20, and Russia's Su-57, which is still in the process of being completed.

6th Generation Fighters: Breaking Technological Boundaries

The 6th generation fighter is in development and is expected to make technological breakthroughs compared to all previous generations.

Advances in core technologies are the foundation for revolutionary changes, not only in the design but also in the way new-generation fighters are operated and used.

These cutting-edge machines represent a fusion of cutting-edge technology, strategic thinking and groundbreaking design, pushing the current limits of air power.

Not simply combat vehicles, they are “smart” systems, equipped with artificial intelligence capable of processing huge amounts of data in real time, supporting quick and accurate decision making.

The 6th generation fighter will have high maneuverability and superior combat performance. They are equipped with advanced engines, modern flight control systems and optimized designs, making them effective in both short-range and long-range air combat.

In addition, they are also capable of flexibly adapting to many different missions such as air defense, ground attack, reconnaissance, and operating in many different combat conditions, providing significant strategic advantages in the deployment and use of military forces.

In terms of design, stealth technology will still play a core role. The 6th generation fighter can be equipped with advanced skins that control heat distribution, reduce the possibility of detection by radar, infrared sensors and heat-seeking systems, providing stealth capabilities across different signal spectrums. Modular design will allow for quick component replacement and easy upgrades in the future.

In terms of features, 6th generation aircraft will be able to operate without a pilot. They can operate fully autonomously or be remotely controlled, opening up completely new air combat tactics.

Advanced artificial intelligence systems will play a key role, not only supporting aircraft control but also commanding drone squadrons in both defensive and offensive missions.

In addition, they will be designed to generate a powerful electrical power source, enough to operate modern weapons such as lasers and hypersonic weapons.

Overall, the 6th generation fighter marks a new step forward in the field of air combat, combining advanced technology, high performance and flexibility.

They are a testament to the relentless advancement of military technology, helping to shape the future of global air power.
