The idea of aircraft generations, which only refers to jet fighter aircraft as opposed to propeller-driven fighter aircraft, first surfaced in the 1990s in an effort to explain the dramatically improved performance of jet fighter aircraft brought on by significant advancements in aircraft design, avionics, and weapon systems.
Jet Fighters Generations Development
First-generation jet fighters (1940 – 1950)
First-generation jet fighters like the F-86, MiG-15, and MiG-17 featured primitive avionic systems without radars or self-defense countermeasures and were armed with cannons, unguided bombs, machine guns, and rockets. This generation of fighters lacked afterburners and flew subsonically.
Second-generation jet fighters (the 1950s – 1960)
Second-generation fighters introduced air-to-air radar, infrared and semi-active guided missiles, and radar warning receivers. Advances in engine design and aerodynamics allowed this generation’s fighters to approach supersonic speeds in level flight. Air-to-air combat was still within visible range, but radar-guided missiles extended engagement ranges.
Third-generation jet fighters (1960 – 1970)
This generation saw improved maneuverability, avionics, and weaponry. They also had the first MiG-23, F-4, and Mirage III multi-role jets. Doppler radar assisted ‘lookdown/shoot-down,’ and off-bore-sight targeting and semi-active guided radio frequency missiles advanced aerial confrontations beyond the visible range. This generation’s aircraft eliminated the need to acquire enemies to neutralize them and achieve air control visually.
Fourth-generation jet fighters (1970 – the 1980s)
In the 1970s and 1980s, improvements in avionics, such as head-up displays and aerodynamic design, led to the development of fly-by-wire fighters such as the MiG-29, Su-27, F/A-18, F-15, F-16, and Mirage-2000. Most of this generation’s fighters could transition between air-to-air and air-to-ground, unlike prior aircraft. This muddled air and strike mission control.
Fifth-generation jet fighters (2005 – present)
Since this article is about 5th-generation jets lets us understand what they are.
So what is the 5th generation of jet fighters?
The Fifth Generation Fighter is the current standard naming convention for ‘next-generation’ fighter aircraft. While there are no truly defined, widely-accepted features of this generation, the aircraft considered for the title often utilize proven features of 4th Generation Fighter designs and introduce all-new levels of performance, stealth profiles, and advanced avionics with integrated all-digital flight systems. The first 5th Generation fighter to reach service was the American Lockheed F-22 Raptor. There are currently several high-profile developments being undertaken in Russia, China, Turkey, South Korea, Japan, and Europe.
With the Lockheed Martin F-22 Raptor, the United States became the first country on earth to field an operational fifth-generation fighter in 2005. When you look at the F-22 compared to its 4th-generation predecessors, the aircraft clearly stands out, but what exactly made it the first of a new generation rather than a more advanced approach to the existing generation of fighters?
The F-22 Raptor stood out from its 4th generation rivals most significantly by incorporating stealth into every aspect of its construction. The F-22’s development targeted stealth from the start, as opposed to first building a fighter for aerodynamics and performance and then looking for ways to lower its radar signature.
So, what, exactly, sets fifth-generation fighters apart from other older generations? A stealthy flying router? Or a multi-role vessel capable of ultra-fast travel?
Generational designations typically emerge from within the aviation community itself. Each generation comes with a somewhat subjective list of qualities that may have existed in some particular aircraft before but becomes necessary across the board for fighters of the next generation.
Since defining “generations” of fighter aircraft is somewhat arbitrary, the Air Force has provided the following breakdown of the technological advancements that led to each new generational label.
- 1st Generation: This generation of fighter jets made use of innovations created during World War II, particularly the jet engine and the sweeping wing.
- 2nd Generation: Range-finding radar, swept wings, and infrared-guided missiles. It included improvements to their first-generation counterparts in terms of speed, armament, and sensors.
- 3rd Generation: Third-generation fighters included more sophisticated radars that could monitor targets at greater distances and semi-active radar-guided missiles that allowed engagements beyond visual range.
- 4th Generation and beyond: High levels of maneuverability, pulse-doppler radar, some degree of sensor fusion, reduced radar signature, look-down/shoot-down missiles, fly-by-wire, and more.
The main feature that set the first 5th-generation fighter apart from other generations was the way stealth was integrated into the design of the aircraft. Additionally, the vehicle had the ability to “hyper cruise,” or maintain supersonic speeds without using its afterburner.
As a result, for a while, super-cruise capabilities were thought to be a component of what makes a fighter of the fifth generation. That is until no other fifth-generation fighter with that capacity entered the air.
Lt. Gen. Jeffrey Harrigian, a former head of the Air Force F-35A Lightning II Integration Office, provides the best definition of “fifth-gen,” in my opinion. He stated, “There are several characteristics of fifth-generation aircraft that separate them from older aircraft,” in an article. Features like radar, infrared sensors, and visual situational awareness tools, as well as self-protection and radar jamming, all work together to make it difficult, if not impossible, for adversary systems to detect, track, and engage the aircraft.
Additionally, the integrated avionics of these aircraft autonomously fuse and prioritize data from the aircraft’s multi-spectral sensors and offboards it, giving the pilot a clear picture of operations in real time and allowing for the download of data for post-mission analysis.
Now, we’ll be looking at the best 15 fighter jets of the fifth generation in the list below. Jet will keep getting better and better as we do down the list.
Top 15 5th Generation Jets
Boeing–Saab T-7 Red Hawk
The Boeing-Saab T-7 Red Hawk is an American/Swedish supersonic advanced jet trainer built by Boeing in collaboration with Saab. It was originally known as the Boeing T-X (later Boeing-Saab T-X). The United States Air Force (USAF) declared it the winner of the T-X program on September 27, 2018, and it will take the position of the Northrop T-38 Talon as the service’s advanced jet trainer.

Northrop YF-23
The single-seat, twin-engine Northrop/McDonnell Douglas YF-23 stealth fighter technology demonstrator was created for the US Air Force (USAF). The design competed against the Lockheed YF-22 for a manufacturing contract in the USAF’s Advanced Tactical Fighter (ATF) competition. The YF-23 prototypes known as “Black Widow II” and “Gray Ghost” were constructed.
The USAF started seeking a replacement for its fighter jets in the 1980s, particularly to compete with the USSR’s sophisticated Sukhoi Su-27 and Mikoyan MiG-29 aircraft. The USAF chose design ideas from Northrop and Lockheed out of those provided by a number of corporations. While Lockheed, Boeing, and General Dynamics created the YF-22, Northrop collaborated with McDonnell Douglas to create the YF-23.

Mikoyan MiG-LMFS
The MiG-XX, also known as the Mikoyan LMFS (Light Multi-Function Frontline Aircraft), was a light Russian single-seat all-weather stealth multi-role combat aircraft. The company’s PAK FA design, which was turned down in favor of Sukhoi’s, and the lessons discovered from the scrapped Mikoyan MiG-1.42/1.44 are both used to create the final product.
It was intended to take the place of the Mikoyan MiG-29 and MiG-35 and serve as a more cost-effective upgrade to the PAK FA, which later evolved into the Sukhoi Su-57. When Sukhoi debuted its own LTS medium-weight single-engine stealth fifth-generation fighter in 2021, the project had stopped being worked on.

HAL Sukhoi PMF/FGFA
The Sukhoi/HAL Fifth Generation Fighter Aircraft (FGFA) was a fifth-generation fighter concept being developed jointly by Sukhoi and HAL for the Indian Air Force. It was based on the Russian Sukhoi Su-57. Earlier known as FGFA, the united project was then known as Perspective Multi-Role Fighter (PMF).
The finished FGFA was supposed to have 43 upgrades over the Su-57, such as cutting-edge sensors, networking, and combat avionics. The Indian version would include a pilot and co-pilot or a weapon systems operator, and it would have two seats (WSO).
India reportedly left the FGFA program in 2018, although there was also a hint that the project would be picked back up later after the Su-57 becomes fully operational in the Russian Air Force. Yuri Slyusar, General Director of United Aircraft Corporation, asserted that India and Russia are still collaborating on the FGFA development and that it has not been canceled.
