Stealth technology is the modern advancement in military aircraft and other weapons. It involves the use of advanced technology and modern design to prevent the aircraft from getting caught by the radar. It also makes use of technical materials that helps the aircraft in deceiving the radars. In short, this technology makes the aircraft and different equipment less visible to radars and other detection devices. In this article, you will get the entire information about how does stealth work.
So How Does Stealth Work?
The use of stealth technology has increased to a great extent in the military equipment. The continuous rise in it can be attributed to the advantages that it gives. The ability to hoax the radars and making the movement of aircraft easier are beneﬁcial for military operations. It makes the aircraft, submarines, missiles, and ships less visible to the radars, infrared rays, and other detection devices. It has gained popularity in recent days as most of the countries want to attain protection from their enemy countries.
But it is interesting to know how this stealth works and accomplish the different missions. First of all, it is better to know about how does the radar works. The radar sends the radio pulse in the direction in which it ﬁnds the object. In other words, it transmits the signals in that direction and checks for the presence of the target.
In case, these signals get reﬂected back to the radar, then it will be caught by a receiving antenna. The collected signals are then interpreted into the form of a blip on the radar screen. It is found that the size of the blip depends upon the volume of signals reﬂected back by the target. It means that the more the signals received by the antenna, the bigger the blip will be and vice-a-versa.
The way stealth works is that it is designed to hoax this radar and ensure that the speciﬁc object can easily move and accomplish its target. It works in two ways:
- Absorption of the signals, and
- Deﬂection of the radio pulses
In the ﬁrst method, the stealth works its magic by absorbing the radio waves emitted by the radar. It means that the waves that come from the radar reach the object but don’t get reﬂected back to the radar antenna. It is absorbed by the stealth aircraft and doesn’t get back to the radar system.
This absorption is done either through the radio-absorbing material such as dielectrics and composites or through the paint. Both these things work effectively in this purpose. All this happens through a mechanism. The coming radio waves are converted into heat energy and get absorb within that material or paint.
In another way also, the stealth work by absorption of signals. The aircraft with stealth technology has small pyramids like structures on the exterior of the plane. Between these pyramids, the radio signals absorbent material is present that fulﬁls this task. It works in the way that these pyramids make the radio waves bounce towards the radio absorbent material. Then, it stops the waves from getting reﬂected back to the radar.
The second method involves the deﬂection of the radio pulses. The aircraft deceives the waves by the process of deﬂection. The aircraft contains a lot of angles which make the radio pulses bounce in different directions other than the normal path. This makes the particles of the waves weaker and is reﬂected in a very small amount. It is not possible for the radar to use them and track the object. Also, no ﬂat surfaces are present in it. It provides a great beneﬁt to the aircraft to ﬂy closer to the radar without being detected.
The above ways don’t make the aircraft invisible to the radar but it delays the entire procedure of the radar system. This means that the radar will catch the aircraft after a speciﬁc time. But it is enough for the aircraft to complete its mission and is about to return to its place. So, it is better to say that stealth technology is a ‘low-observable’ technology.
Future Advancements in The Way Stealth Work
The way stealth work is constantly evolving. The use of this technology is extending from the aircraft and ships to missiles and satellites. It helps in getting protection from the enemy countries as well as receiving upgraded equipment for the military. However, there are some disadvantages also, which are against the stealth technology such as:
- With the rapid changes in the technology of the radar systems, stealth technology is working for only a certain range of radar pulses. The modern radar systems like L-Band radar are capable of tracking the location of aircraft with stealth technology.
- Many radars have the capability to search for the objects in a particular area. The advanced system of Infrared Search and Track is making possible the task of tracing the stealth aircraft. Even it has the potential to detect it quickly. It makes use of the Infrared Signatures of the aircraft to complete this task.
- Another minus to the stealth technology or stealth aircraft is that it becomes visible whenever it releases its missiles or weapons.
- Another drawback of this technology is that it requires a very huge cost for manufacturing. Also, the cost of operating and maintaining it involves a large expenditure.
In the future, stealth technology is believed to get more advance and accurate. This means that it will be able to counter modern radars and reduce its limitations to a great extent. In the future course of time, the use of this technology will be extended to more of the military weapons. The transport aircraft, rotary wings, and other military bases will come under the inﬂuence of this technology. Its use will expand and play an important role in air weapons.
The advancement will come which can beat the radar systems and use some other devices to deceive them. Efforts will be made to reduce the costs of the stealth-based weapons. However, the challenge of beating future radars will also remain. As the radar systems will also get more advanced and quicker and thus, may fail this technology. Overall, it is expected that both stealth technology and radar systems will be developed in the way that they can counter each other.
They way stealth work is one of the best secret for the stealth technology companies. Beyond the basic working, not much is available in the public domain. However, stealth technology is an integral part of the aircraft and other military weapons.
The thing behind its increasing use is that it can protect them from the radars and further retaliation of the enemy country. This increases the safety of the military resources and also improves the possibility of proper completion of the mission. In the future also, the use of this technology will continue and even expand to most of the equipment. It is expected that the use of this technology will continue for many years and serve the aircrafts with its service.
