All weather amphibious assault ship

On August 5, under the escort of many tugs, the bow ship of type 075 amphibious attack began its first trial voyage. Since the ship was officially launched on September 25 last year, the outfitting time is less than 11 months. It has overcome the adverse effects of shipboard production accidents and completed the installation of Shipborne weapons, electronic equipment and other shipborne systems. As the first ship of a new type amphibious attack ship, the construction speed of 075 is quite rapid.

As the largest tonnage warship built and launched in Huangpu River, there are still many difficulties for 075 to navigate safely in Huangpu River. Therefore, during the trial voyage of the type 075 first-made warship out of Huangpu River, the peoples Navy also did its best, including four type 072 tank landing ships and a number of frigates, which were originally berthed on the Whampoa side wharf, all left the Huangpu River for temporary shelter before the 075 first made warship set out, so as to make contributions to this future comrade in arms Out of more spacious waterway waters.

We have boarded five ships and sent out many ships to welcome the first voyage of new quality combat forces

From the perspective of construction progress, it took 10.5 months to make the bow of type 075 amphibious attack ship from launching to the first sea trial, which was shorter than that of the first domestic carrier Shandong warship from launching to the first sea trial for 1 year and 17 days. However, considering the complexity of aircraft carrier structure, this time gap is not surprising. Since the first sea trial mainly carried out power system test, some other equipment on board the ship It is normal that the equipment is not fully debugged or even installed.

However, compared with the status of the ships hull structure when it was launched and only a few angles of view in the outfitting process, the sea trial gives the outside world a rare opportunity to observe the appearance of this basically completed new amphibious assault ship from various angles, and obtain more information about this type of amphibious assault ship.

As an amphibious assault ship with huge internal space, although there is no doubt that the ship will be equipped with hangar, dock hold, vehicle deck and a large number of Marines cabins, the distribution of the above parts in the ship and the size proportion of the space occupied can not be clear at a glance, so we can only infer the interior of the amphibious assault ship from some features of its appearance and overall layout.

On the 075 amphibious attack ship, we can not only infer the approximate size of the hangar on the ship, but also infer the approximate space proportion of the other parts of the ship from the space occupied by the hangar on the ship, and further analyze the mission requirements of the Chinese Navy for various types of ships embodied in the 075 amphibious attack ship, and the distance of the 075 type amphibious attack ship The great value of naval amphibious combat ship formation.

The arrangement of elevator with smaller tonnage of northwest wind

For all kinds of flat deck aircraft carrier using elevators, the location of elevators is generally arranged at the edge of the hangar on the ship, and the distance between them is as far as possible, so that the carrier based aircraft in every corner of the hangar can be quickly lifted to the flight deck; at the same time, in order to take care of the take-off and landing, scheduling and servicing operations of carrier based aircraft on the flight deck, the elevator is in flight Attention should also be paid to the position on the deck to facilitate the dispatch and operation of carrier based aircraft and not to affect other normal operations on the flight deck.

On type 075 amphibious attack ship, two large elevators can be seen: the trailing edge of the front lift is flush with the front of the island, indicating that the starting point of the hangar may be at the front or rear edge of the lift; the rear lift is located at the stern, indicating that the trailing edge of the hangar is straight to the stern. In this way, the length of hangar deck on the type 075 amphibious attack ship with a length of 240 meters should be at least 130 meters, and its area is likely to exceed the US hornet class amphibious assault ship with similar tonnage, reaching the level of us class. The larger hangar area undoubtedly means more helicopter carrying capacity, which will naturally put forward higher requirements for the carriers aviation fuel carrying capacity.

For the Chinese Navys amphibious landing formation, in most cases, the amphibious attack ship will avoid fighting alone, but will form a formation with 071 integrated landing ship and even 072 tank landing ship, and act as the core of the formation for joint operations. In each formation, 075 amphibious attack ship must rely on its strong aviation operation ability to undertake the core task of launching air vertical landing operation, and as the core of formation to master the battlefield situation, and to undertake the heavy task of formation command ship.

In contrast, the plane landing combat capability of type 071 integrated landing ship is also among the top in the worlds dock landing ships. In addition, its large number of equipment is enough to make up for the relatively short board of 075 in this combat capability. From the point of view of balanced loading, the 075 has the ability of vertical landing and plane landing, which makes the warship have the ability to carry out amphibious operations independently, which increases its operational flexibility.

For the operational needs of the peoples army in the next few years, 075 and 071 are complementary to each other

Although the Chinese navy has the second largest amphibious transportation force in the world, and the high sea amphibious combat capability represented by the 071 integrated landing ship has taken shape, the weakness in the vertical landing operation capability represented by the amphibious assault ship is still very serious so far. As a result, compared with the state that the general state of building amphibious assault ship is shallow to stop or the United States maintains its normal rotation rhythm after forming a certain equipment scale, the construction speed of type 075 amphibious assault ship can be regarded as rapid -- just before and after the first 075 ready for sea trial, the hull structure of the third type 075 amphibious assault ship has been completed in Hudong Shipyard In the dock, the prototype was first seen.

This means that the Chinese navy will build and equip three 075 amphibious attack ships in a short period of time, so as to form the situation that amphibious attack ships can be used at any time, just like aircraft carriers. This will not only bring severe challenges to the rapid formation of combat effectiveness of the Chinese Navy, but also lead to the rapid expansion of the carrier based transport helicopter unit of the Chinese Navy aviation force. However, when all this dust settles, the PLA will no longer need to carefully plan operations to launch landing operations at the synthetic battalion level and amphibious landing operations at the synthetic brigade level in the east of Taiwan It can be the new normal that opponents have to consider in the Taiwan Strait situation, just like Dongfeng washing the ground.

In short, as 075 moves towards maturity, it is not good news for Ilan 153 brigade

What kind of new light tan India needs

Due to the fact that the military confrontation between the Chinese and Indian armies in the western part of the border has not ended, and the Indian government and military are trying to take this opportunity to meet their actual needs, the Indian army has carried out preparation procurement activities on the ground of tense border situation. Recently, there is a new wish list - as many as 300 light tanks that can be maneuverable in the air.

For the Indian army, the military pressure of the eastern line is greater than that of the western line, and the rapid armor of a certain brigade is unimpeded in the east line

From the perspective of the Indian army itself, the demand for light tanks has existed for a long time to some extent: the relatively weak infrastructure construction in India, especially in the border areas, is not friendly to the effective use of T-72 and T-90 main battle tanks with a total combat weight of more than 45 tons. Although India claims to have more than 8 million kilometers of roads, most of them are not hardened The gravel road or even dirt road on the road is not suitable for the rapid movement of armored forces. Although Indias railway lines extend in all directions, their extremely low operational efficiency makes it difficult to guarantee the speed of armored forces as a means of campaign and strategic maneuver. In addition, there are many areas in India where light tanks are needed, so the Indian army has been dealing with light tanks for a long time The indifference of equipment is a little strange.

However, according to the Indian media reports and the statement of the Indian Ministry of defense, the purpose of Indias light tank purchase this time is not to mend the wounds after a sheep is lost, but a pure mentality of comparison. Because the Indian army learned from the public reports of China that the PLA has listed type 15 light tanks equipped with excellent plateau mobile combat capability in the Tibet Military Region, the tit for tat should be equipped with the same equipment Class.

The Indian army does not have a T-90 on the east line, nor does it have a T-90 in the direction of Liecheng

It was a bit unreliable to carry out arms construction with a childs family mentality, and then the media reported that the Indian armys model selection in purchasing light tanks was even more confusing.

The preferred light tank of the Indian army is the Russian made Octopus light tank. Although this equipment has entered the active service of the Russian army and the system itself is relatively mature, the Indian army can theoretically obtain a batch of finished products for use in a short period of time. Moreover, the 2a75 125 mm gun and cartridge type automatic loader with the same diameter as the Indian armys active tank also facilitate its logistics support, and the 18 ton battle The full weight can also be easily transported by air or even dropped by air. However, the low weight adopted by the vehicle for airborne landing leads to its extremely low protection combat capability, and the fire control system of its active model is also quite simple. Even if the improved model introduced by the Russian army, its information warfare capability is lower than that of the 15 type light tank.

In addition, in terms of the most critical maneuverability, the octopus, which can achieve a power to weight ratio of 28 horsepower / ton in low altitude areas, has not been optimized for plateau environment, and its engine power will be reduced by 30-40% at altitudes above 3500 meters, fuel consumption will be increased by 30-50%, and the maneuverability will be greatly reduced. As an equipment designed to fight against type 15 light tank, the overall performance of octopus is almost unqualified.

Octopus does not have a high ton power ratio, and its supercharged engine is difficult to play in plateau environment

Perhaps because of this consideration, the defense research and Development Organization (DRDO), which represents Indias light of China, has also proposed two self-developed light tank schemes and proposed to develop three prototype vehicles within 18 months. One of them originated from the plan of Indias own light tank, which was put forward in 1983 and was abandoned as early as 1996. It uses the chassis of BMP-2 infantry combat vehicle which can be produced by India and carries the 105 mm gun turret of legal system. However, this scheme has been abandoned for a long time, even if its performance is restored, it is seriously behind the times.

As a result, another more advanced and bolder solution has been proposed: to use the chassis of Korean K-9 self-propelled gun, which is being licensed by India, and to replace the modular turret developed by John Cockerell defense company of Belgium, which can use 105mm or 120mm guns.

DRDO light tank scheme in PPT state

From the perspective of technical feasibility, it is possible for India to convert the K-9 self-propelled gun into a light tank by outsourcing the turret. The modular turret developed by John Cockerell defense company and its artillery performance are of good international level. With the K-9 self-propelled gun chassis and 1000 horsepower engine, it can also have good maneuverability in theory.

However, on the one hand, the original weight of the K-9 self-propelled gun is as high as 47 tons. Although the replacement of the turret can reduce its weight, its total weight is difficult to be greatly reduced. In particular, as a self-propelled gun, in order to facilitate the operation of the gun crew, the internal space of the K-9 is relatively large. When it is converted into a light tank, the space utilization is not complete or the vehicle structure is not enough Another problem that can not be solved is its protection capability. Due to the origin of the K-9 self-propelled gun, the protection capability of the vehicle itself is quite limited. Moreover, due to its large weight, it is also difficult to further enhance the protection. In addition, considering the problem of engine power reduction on the plateau The prospect of replacing the K-9 with a light tank is clearly not optimistic.

The K-9 self-propelled gun with x1100-5a3 integrated hydro mechanical transmission system and hydro pneumatic suspension is the best combat vehicle of Indian army, and naturally becomes the alternative of light flat chassis

How to choose between protection, firepower and mobility has become the main problem of modern lightweight MBT

In this series of light tanks, only Chinas type 15 light tank is taken as a special case. From the very beginning, it emphasizes its special operational environment, develops new light tanks around the operational requirements in plateau environment, and strengthens the tanks protection capability as much as possible while ensuring the firepower and mobility. Finally, the type 15 light tank becomes a kind of light tank that can meet its expectation At the same time, it has strong protection ability and survival ability of superior equipment. To a certain extent, this kind of attitude of equipment research and development, which starts from the beginning, is exactly what Indias weapons and equipment research and development, which is targeted, short and quick, lacks.

Can India catch up with Chinas tank industry in 60 years
