Over the past few years, every countries has been trying to bring about changes in fighter jets and they are also succeeding in them. For example, the fourth generation fighter jets have evolved into the 5th generation, which has technologies like stealth, embedded sensors, data networking and sensor fusion. But Today, several countries are developing or planning sixth-generation fighter programs as they seek to introduce more advanced capabilities.

So, in this article, we'll compare 5th-generation and 6th-generation fighter jets in areas such as stealth, sensors, artificial intelligence, weapons, electronic warfare, networking, drone integration, and combat capabilities. We'll explore what makes the 6th generation unique and what changes will occur compared to the 5th-generation fighter jets. 

 So, let's get started : 

First, let's understand what a 5th-generation fighter jet is ?

5th gen jet

5th-generation fighters are among the most advanced fighter jets currently in service. These jets were designed with a focus on embedded sensors, stealth, sensor fusion, networking, and the ability to detect and intercept threats. One of the special features of these 5th-generation jets is that they are not easily detected by their opponents, which reduces their chances of being detected during combat.

The strength of 5th generation fighter jets compared to previous fighter jets lies not only in their speed or structure, but also in the combined work of its various systems such as radar, infrared sensors, electronic warfare systems or various information resources, which provide the pilot with a clear picture of his mission objectives on the battlefield, with the help of which the pilot can easily achieve his target.

5th generation fighters are different from each other in each country, they have different capabilities in terms of design, technology and required quality. For example, we have the F-22 Raptor and the F-35 Lightning II. You can guess their characteristics and power.

Key Features of 5th-Generation Fighter Jets :

1 - Stealth Technology :

Stealth Technology  info-graph

Stealth technology is actually a technology that helps avoid detection by opponent's radars, meaning that with this stealth technology, A fighter jet is not 100% protected, but stealth can reduce its chances of being detected and targeted by an opponent..

2 - Advanced Sensors & Sensor Fusion :

AESA radar, infrared sensors and other radar systems collect information and provides to the pilot with clear picture of the battlefield for his mission, allowing him to easily acquire his target.

3 - Network-Centric Warfare :

5th Generation Jets can use Network Centric Warfare to receive or share information with friendly/authorized network's, aircraft, ships, other fighters, drones, AWACS and both land and naval systems. That is, Network Centric Warfare helps in sharing information with different friendly forces, in simple words it means getting or giving information by talking to every branch of the military.

4 - Advanced Electronic Warfare :

Advanced electronic warfare can actually evade an adversary's radar, detect, jam, or deceive an adversary's radar by tracking and engaging the target, that help jet's to improve its chances of successfully completing its mission and returning safely.

5 - Internal Weapons Bays :

5th generation fighters have compartments built into the interior of the jet to store weapons, and these compartments are called internal weapons bays. While in conventional fighter jets, weapons compartments are built outside the IBs, which are called external hardpoints or pylons.

6 - Advanced avionics and cockpit systems :

Advanced avionics and cockpit systems are systems installed in front of the pilot in the cockpit of a fighter jet, such as the HUD (Head-Up Display)screen and other electronic systems, which help the pilot understand and manage navigation, sensors, communication, and targeting and flight information, so that the pilot understands the battlefield and operates the flight accordingly.

7- Multi-role combat capabilities :

In multi-role combat capabilities, fighter jets are not only used for air-to-air combat. Instead, fighter jets can be used for various missions, such as air-to-ground attacks, surveillance, reconnaissance, and air defense, meaning they are also used to protect our borders. This capability is called multi-role combat capability.

Now, Let's Understand What a 6th Generation Jet is ?

6th gen jet

6th generation fighter jets are being developed for the air war of the future. These 6th generation aircraft include capabilities such as sensors, advanced stealth, electronic warfare, artificial intelligence, unmanned technologies and networking. The United States, China, Japan and Italy (GCAP) and other countries are also working in this race to build the 6th generation.

As I have explained the definition of 5th generation stealth technology, here in 6th generation the same stealth technology is being modernized to keep the jet safe from the adversary's radar and other detection systems. That is, 6th generation fighter jets are being designed in such a way that their radar signature and other detectable signals become more difficult for the adversary to detect and track.

(Main) Key Features of 6th Generation Fighter Jets :-

1- Artificial Intelligence (AI) and Machine Assistance :

An important feature of 6th generation fighter jets is AI, which will greatly assist the pilot. AI will actually collect information from sensors and systems. That is, the information received by the AI ​​from the sensors and aircraft systems will be processed quickly and will help the pilot understand threats, targets, and battlefield conditions.

2- Advanced Sensors and Sensor Fusion :

Advanced sensors will play a key role in 6th generation jets. This means that these 6th generation aircraft will collect information from various sensors, such as radar, infrared sensors, and other detection systems.

Sensor fusion works by combining information from different sensors to create a clear picture of the battlefield, helping the aircraft's AI systems track threats and targets for the pilot.

3- Advanced Electronic Warfare :

Advanced Electronic Warfare, which is being developed to be more advanced than 5th generation fighter jets, aims to detect, monitor, jam or deceive an adversary's radar, electronic systems and communications. This will provide the pilot with better protection against the adversary's electronic systems, giving the pilot an advantage in achieving his target.

4- Unmanned and Optionally Manned Capability :

Unmanned and optionally manned capabilities could also be a key feature in 6th generation fighter jets. This means that some next-generation jets could be designed to operate autonomously or remotely without a pilot. In the future, this feature could allow some missions to be performed with a pilot and some missions without a pilot.

5- Drone and Loyal Wingman Integration :

6th Generation jets are designed to operate alongside loyal wingman aircraft and drones. This means that drones will be able to work alongside fighter jets to perform surveillance, reconnaissance, electronic warfare, and engage adversaries.

The primary job of a Loyal Wingman would be to operate a manned fighter with multiple unmanned aircraft, i.e. drones. The pilot would be able to coordinate and direct these drones, allowing the pilot to direct them to dangerous areas rather than going there themselves.

6- Advanced Networking Data Sharing :

Advanced networking and data sharing will also play a key role in the 6th generation. This will allow the fighter jet to share information from its sensors and systems with other platforms, such as other jets, AWACS, ships, ground systems, and drones. This networking will allow the mission-ready jet to remain connected to other platforms, giving the pilot a more complete picture of the battlefield/mission.

7- Human-Machine Teaming (AI)

Human-Machine Teaming In the future, pilots, AI, and unmanned systems will work together as a team. As mentioned in the text above, AI will help the pilot understand the mission target situation and make decisions by quickly processing the information data received from the aircraft’s sensors and systems. This feature will allow the pilot to use the capabilities of AI and drones for their mission instead of performing each task/mission alone, which will significantly improve situational awareness and combat effectiveness.

Overall Difference of 5th Generation vs 6th Generation Fighter Jets :

Difference of 5th Generation vs 6th Generation Fighter Jets 

5th generation Difference:

5th generation, Designed with stealth, improved sensors, sensor fusion, super cruise, and network-centric warfare as a focus. The pilot is the decision maker and the plane provides information and support to him/her.

6th Generation difference:

6th generation, Expected to take this concept much further by transforming the fighter into a highly integrated combat system. AI, autonomous capabilities, advanced networking, unmanned teammates, and human-machine teaming could allow the aircraft to coordinate with multiple platforms rather than operating primarily as a fighter.

Main Difference of Both : 

5th generation = highly advanced individual combat aircraft

6th generation = potentially a connected combat system built around a crewed or optionally unmanned fighter

Now, Let’s Compare the 5th and 6th Generation Fighters

Comparison of 5th and 6th Generation Fighters

As you have understood the characteristics of these two generations, let's now directly compare the 5th and 6th generation fighters and see what the real difference is between them.

The biggest difference between 5th-gen fighters and 6th-gen fighters is not just advanced sensors, better weapons, or better stealth. Rather, the real difference lies in the combat environment and battlefield role that these aircraft are being built with in mind.

5th generation fighters were developed to give pilots an advantage in their missions on the battlefield through advanced sensors, stealth, networking, sensor fusion, and highly integrated combat systems. 5th generation aircraft are designed to detect threats, take immediate action and share information, and engage targets. These capabilities make these aircraft difficult for adversaries to detect and track.

6th-generation fighters are expected to take this concept further. They will focus not just on being a highly capable fighter, but on being part of an integrated combat ecosystem. A 6th-generation fighter could in the future work in conjunction with unmanned aircraft, drones, other fighters, satellites and ground or naval systems, while AI and advanced networking could play a key role in integrating information and missions.

Simply put, the 5th generation focused on making the fighter itself highly capable, while the 6th generation focuses on operating the fighter and its associated systems as an integrated combat network.

The role of the pilot in 6th-generation fighters could also change in the future. With the help of AI and autonomous systems, aircraft systems will be able to perform more data analysis, mission support, and coordination tasks, rather than requiring the pilot to handle everything manually.

In 5th generation aircraft, the pilot maintains the primary decision-making role in the flights while the onboard systems assist him through analysis and enhance his domain awareness. 

6th generation aircrafts are likely to involve more artificial intelligence in the process of analyzing situations and providing support to the pilot for decision-making. This is likely to free the pilot to concentrate on making more important choices.

This does not mean that 6th-generation jets will do away with human pilots. In fact, the trend appears to be towards human-machine teaming in which humans and machines work in concert. There is likely to be a blurring of roles between autonomous machines and humans in future combat.

In short, 5th generation fighters are likely to herald the era of stealth, advanced sensor technologies and network centric warfare. By contrast the 6th generation programs are expected to lead to a more connected, autonomous, distributed and intelligent form of warfare.

If you want to know what upcoming 6th-generation fighter jets will be like in the future and what features they are expected to have, then this post can be very informative for you.
