News Background: 4 end of India’s first ship made invisible ships ‘Shivalik’ frigate formal service. Indian media said the effects of this stealth warships warships make India into the top ranks of the country of manufacture. Service ceremony, the Indian Defense Minister AK Antony said: “For the Indian Navy, the Indian army and the Indian shipbuilding industry, and today are worthy of letters of the day.” In this regard, countries have to vote to the attention. How stealth surface ship? What are the specific indicators of stealth? What is the future development trend of … … on this hot topic, newspaper correspondent recently interviewed the Naval Command College, Professor Pang following the first.
invisible urgent need to achieve more difficult
Q: stealth frigates for India’s first aircraft delivery, how do you interpret this?
A: This is the meaning of the Indian Navy does not generally. The success of the first ship built in India described the development of shipbuilding technology to a new level, master of the stealth of this new technology; followed by the Indian Navy combat ship put into service marks have been significantly improved.
Q: Why did the Indian government and the media reaction would be unusually warm?
A: The ships of the Western developed countries in terms of stealth technology, and not quite fresh, and for India to achieve from scratch, is a breakthrough. Surface ships with the urgent need for stealth and stealth to achieve the desired results are quite difficult. India to achieve a breakthrough, high-profile expression of feelings are understandable.
present, the invisible nature of naval surface ships has become one of the key technical indicators. It not only changed the surface ship design ideas, but also changed the way the use of surface ships.
Q: Can you invisible on the surface vessel, “needs urgent,” “very difficult” detailed explanation about it?
A: surface ships in the sea the most fatal weakness of the field is hidden hard, hidden poor means the defensive. Over the years, surface ships has always faced a serious threat, making it extremely urgent needs of the invisible. To really invisible, is technically very difficult. Make it clear that these problems, the best use of relevant terms of reference.
Q: Please explain further with reference?
A: In addition to surface ships, submarines, naval and ground planes of the main characters there, they already have good performance in stealth, to help them as a reference to a broader perspective and a high level understanding of the problem.
and submarines than the first. Coverage of sea surface ships no shelter, directly and prominently exposed to the radar, infrared, magnetic and optical and other detection equipment under. Due to technical constraints, surface ships is difficult to completely eliminate their target features, such as: radar, infrared radiation, visible light characteristics and magnetic characteristics, it was found that the probability of detection equipment, much higher than the submarine.
then compared with the aircraft. Was easily found and easy to hit the area, the major surface ships and aircraft of different platforms, including geometry, velocity and movement space in three areas. First, surface ships much larger than the dimensions of the aircraft, a few dozen tons of combat aircraft can be achieved through technical means better stealth, such as the U.S. F-117A stealth fighter, the radar cross section can be reduced to 0.01-0.02 square meters, only the size of an ordinary fighter with 1/300. And a few thousand tons of warships, in order to achieve a tactical sense of the invisible, very difficult, because the technical means to detect the huge ships were found to be reduced to a safe enough distance range, the difficulty is much greater than the aircraft. Second, the slower surface ships, and aircraft velocity is not an order of magnitude. Surface ships can not be like an airplane in three-dimensional space of free movement, only two-dimensional horizontal movement of the sea, so it is easier to be discovered and attacked.
Thus, surface ships to truly achieve a sense of stealth tactics, technical requirements much more difficult than the planes and submarines.
important indicators of the effect needs to meet the invisible
Q: how to achieve stealth surface ship?
A: The stealth ship is not in the usual sense that the other side completely invisible, but the tactical sense of the invisible – that is, before the ship was found in its combat mission has been completed. Therefore, simply remove the ships deck equipment porthole or reduce to some extent and thus reduce the ship’s radar reflection area, to take similar measures in a single stealth ships, can not be called stealth ship, stealth tactics to reach a certain tactical and technical indicators.
Q: There are uniform standards to define the invisible or not, and the stealth of it?
A: This relates to the quantitative expression of invisibility. Currently, I have not seen this very authoritative standards. Speaking specifically of the ship, can often only hear some of the more ambiguous statement. Such as a ship of the target features down to 500 from 5,000-ton-ton, you can think it is a stealth-type ships. Areas of expertise in the design of stealth, the stealth nature of the technical parameters should be complete. A type of warship stealth performance is usually confidential.
Q: So, the Indian-made stealth stealth frigates in the end to what degree is still a mystery?
A: You can say, because it is not known war on its key technical indicators. If the basis of media reports of the ship, “quietly in the high seas close to the enemy and basically not to be found,” saying that it can be regarded as a stealth warship. However, even a very good surface ships invisible, can not alone on their own tactical actions to achieve the desired effect.
Q: Why do you say?
A: In the fierce sea battle against the field, stealth technology is not isolated to function. Whether using stealth stealth aircraft or ships, but to each other determine the cause of illusion, so that the other late in finding the target, in order to obtain a variety of tactical victories must also match. If the war in Iraq, the U.S. military attack in the use of stealth aircraft, while suppression of information by means of attack and electromagnetic compatible. In contrast, in complete stealth warship combat missions when the need for more tactical coordination. For example, at what time, what direction the organization electromagnetic deception, electronic feint, these tactical measures well-organized, stealth warship to successfully complete the task.
Although there is no real precedent for the development of promising
Q: origin of surface ships when the stealth technology, which uses stealth technology warships earlier?
A: “The Art of War” said: “it is the extreme form of soldiers, as invisible,” and this truth has not changed. Generally believed that the modern sense of the origins of stealth technology during World War II. The use of stealth technology on surface ships, is a gradual process and not a landmark event. From the 1980s, the U.S. military services beginning in the design of new weapons and equipment is widely used in stealth technology, which ships with stealth technology began to rise. In the 1990s, the United States built the “Sea Shadow” stealth test ship, built in Sweden, “Secretary Mickey” stealth missile boats, the French built the “Lafayette” class stealth frigates, which are properties of the water earlier with stealth ships.
Q: surface ship stealth technology development status?
A: In India, before the world had the United States, Britain, Russia, France, Sweden, Japan, Italy, Germany and Israel and other countries have the ability to build stealth warships. Since the 1980s, to improve ship survivability and effective combat capability, increase investment in countries around the world have started on the surface ship stealth technology research and put forward a variety of surface ship stealth concepts, and translate them into practical technology. According to incomplete statistics, the world’s existing no less than dozen stealth surface ship models, a total of twenty-three one hundred.
Q: surface ship stealth development trends?
A: Despite the present, yet invisible surface ships into combat, but can predict the future, the development of stealth States Navy surface ships will be highly valued. Trend in the development, will continue to focus on the use of the latest stealth design, in materials to make a fuss, a lot of use of non-metallic materials and newly developed stealth coating materials and coatings. Meanwhile, the application of stealth technology to the “micro” development, a number of small parts such as masts, sensors, vents, antenna base, columns and other cable systems, a more comprehensive stealth design.
In addition, the sustained and rapid development of artificial intelligence technology and microelectronics technology will also be used in a lot of stealth design. In the future, the entire hull will be laid a variety of special sensors, and the formation of a complete system with adaptive capabilities of stealth. If the ship is sensitive to the detection, stealth system to detect the nature of real-time automatic identification, while the controller so that the shape of ships, stealth materials, corresponding changes in performance to offset or reduce the enemy’s detection capabilities.
