In 2017, the Bombardment-6N first appeared in public view. The picture shows the test flight of the Bombardment-6N. The first tubing of the aircraft is clearly visible.
Bombardment-6K is the only special bomber in service in the PLA. Its history can be traced back to the 1960s. In 1957, the Soviet Union provided technical data and prototype of Tu-16 bomber for reference in order to realize localization. In 1968, Xian Aircraft Manufacturing Factory successfully tested the first localization Tu-16, i.e. Bombardment-6A, and entered active service the following year.
After more than 50 years of use and improvement, the Bomber-6 Bomber Family has included more than ten modifications, which reflect the technical requirements and tactical positioning of the Air Force for bombers.
Before the appearance of Bombardment-6N, the most important modification was Bombardment-6K. It first flew in January 2007, and its shape is quite different from the previous model. The glass hood of the aircraft head was cancelled, and the black radar cabin was replaced. Fire control radar was installed inside. The glass cockpit of the bomb-6 model was realized for the first time, and the total number of wing pylons was further increased to six.
Bombardment - 6K, one AKD - 20 cruise missile is mounted under each wing.
Most importantly, the engine was replaced with the D-30KP-2, and the domestic version of the WS-18 engine of the D-30KP-2 was used in the subsequent improvements of the bomb-6 and the Yun-20. With the addition of redundant equipment and the use of composite materials instead of traditional materials to make part of the fuselage, the overall weight of the bomb-6K has been reduced, thus the bomb-carrying capacity and range have been significantly improved.
In recent years, the PLA has continuously enhanced its anti-intervention/regional rejection capability. Among them, it is an important task for the Air Force and Naval Aviation Force to deliver precision guided ammunition through large-scale air platforms with heavy loads and large voyages, and to resist enemies outside the disputed areas.
The Air Force has gradually changed from flying out to attacking out, and the long-distance training of bombers will become more frequent. The picture shows the joint cruise exercises of the Chinese and Russian air forces in July this year. There will only be more and more pictures like this.
Although bomb-6 can also mount traditional aerial bombs for aerial bombing, its attack survivability and efficiency are not as good as tactical attack aircraft in the face of a perfect modern air defense network.
Taking the experience of the US military in Vietnam War as an example, the bombing of important targets in northern Vietnam was mainly accomplished by F-4 and other tactical attackers, while the B-52 strategic bomber was sent to bomb the sub-important targets in southern Vietnam. The total number of B-52 sorties was only 6%.
The J-7 can carry four Hawk Strike-83 or two Hawk Strike-91, but it will sacrifice mobility and voyage, and its survivability is worrying in the face of a well-organized air defense formation at sea. Moreover, the threat to large aircraft carrier formation is limited by the performance of these munitions, and more fighters need to be dispatched at a single time, which is a big test for coordination and logistics. At this time, the advantages of large bombers are highlighted.
This is mainly because strategic bombers such as the B-52 do not have the ability to break through the enemys dense air defense network. It is difficult to accurately target and drop bombs even if they luckily break into the target, but tactical attackers can achieve better bombing effect by virtue of their maneuverability and low-altitude flight performance. It can be said that the use of strategic bombers to carry out these tasks is a waste of resources, so the U.S. military equipped with B-2 stealth bombers at the end of the last century to solve this problem.
Today, with the emergence of new long-range guided ammunition as an opportunity, strategic bombers have re-possessed new powerful strike means, which is also an important reason why old-fashioned bombers like B-52 and Tu-95 are still active all over the world.
B-52 can carry AGM-158 cruise missile, so that it has the ability to attack outside the defense zone, and no longer need to risk air bombing.
In many modifications of Bombardment-6, its aerodynamic shape has not been greatly changed, so its high-speed flight performance, maneuverability and stealth performance have not been significantly improved. This also shows that Bombardment-6 has gradually turned to the role of missile air launch platform, mainly highlighting the large range, with perfect communication, navigation and detection equipment, and The advantage of large ammunition loading capacity is to execute precise strike tasks outside the defense zone. This change basically coincides with the development direction of the international mainstream.
Therefore, to continue to improve the Bombardment-6, it is necessary to expand the range, in the case of no major structural changes, equipped with air refueling equipment is the best way. ?
The number of dedicated tankers previously equipped by the Air Force is limited, and the refueling capacity of the modified bomb-6 is not enough, so even equipping the bomb-6 with refueling equipment is difficult to play a role. However, with the batch loading of domestic transport-20 transport aircraft in recent years, the large air refueling aircraft modified on the basis of it should also be in service soon, thus further extending the range of large missile-borne aircraft.
Above is the air refueling CG chart of the refueling engine refitted on Yun-20 platform. With the improvement of anti-intervention/area rejection capability, the combination of tanker and bomber will appear more and more frequently. We still have a long way to go to coordinate bombers, tactical attackers, refueling aircraft, electronic warfare aircraft, early warning aircraft and other functional aircraft into a perfect combat system in order to deal with potential threats in an all-round way.
Compared with land-based and sea-based cruise missiles, missiles launched by bombers have many advantages. Because of the higher initial speed given by the carrier aircraft, the range of air-launched models can be extended. The reaction speed and mission flexibility of bombers are also stronger than those of land-based and sea-based launch platforms.
Bombardment-6K, which is displayed at the air show, is loaded with AKD-63 and AKD-20 cruise missiles.
For example, the active Bombardment-6K cruise missile can be mounted AKD-20 or AKD-63, the former is the air-launched version of the land-based Long Sword-10 cruise missile, and the bombing-6K can mount six at a time. The ground-based version of the Long Sword-10 cruise missile has a range of about 1500 to 2500 kilometers, and the air-launched version may have a higher range. It is speculated that the operational radius of Bombardment-6N may be extended to more than 5000 km by single aerial refueling, and the combination of the two can effectively cover the targets within the Second Island Chain.
More interesting is whether the bomb-6N will mount the air-launched version of the Dongfeng-21D anti-ship ballistic missile. Dongfeng-21D is Chinas first land-based mobile anti-ship ballistic missile system, which was officially released in 2015.

According to foreign media, China has developed an air-launched anti-ship ballistic missile on the basis of Dongfeng-21D and carried out several tests. The US military has temporarily given the missile the symbol of CH-AS-X-13. If transplanted successfully, the theoretical longest range of the missile will approach the lower limit of the Intercontinental missile.
In September 2017, Russia launched the Kh-101 cruise missile Tu-95 to attack terrorist camps. The missile has a range of 2500 to 2800 kilometers and is a nuclear-conventional missile. The air-launched version of DF-21D may be capable of carrying nuclear warheads.
Although there is no public information, since the range has been increased and more new ammunition may be mounted, it can be inferred that besides refueling capacity, the communication and navigation equipment of bomb-6N should be improved to a certain extent than that of bomb-6K. Therefore, Bombardment-6N not only has the refueling capacity, it should undergo an all-round comprehensive upgrade.
In general, the potential of the platform will be explored through the continuous upgrading of avionics and weapon equipment. The improved bomb-6 still has strong Tactical Attack Ability and strategic deterrent force. Before the advent of the next generation of bombers, it was still a powerful pillar of our air combat and deterrence.
