Promising air defense system LOWER AD. Cheap addition for the Patriot
Layer system
The development of new means of operational-tactical air defense is still carried out mainly at the level of general concepts and the development of requirements for equipment. The Combat Capabilities Development Command (CCDC) plays a leading role in this process. Last fall, the CCDC announced the main considerations on this topic and revealed possible ways for the development of air defense. Over the past time, development has progressed noticeably, and one of them will soon be tested.
The concept of air defense is formed in connection with the emergence of new characteristic threats. In recent years, there has been a steady increase in the risks associated with unmanned aerial vehicles - single or group. The development of precision weapons of all classes also continues. To counter such threats, new defenses are required.
The new concept of defense from CCDC provides for the creation of a layered system, including six "layers" or "domes" that protect a given territory and objects on it. Different "layers" include different means. It is proposed to use new radar systems, laser and missile interception systems. The largest sixth "dome" is proposed to be created using the promising LOWER AD air defense system. Its task is to detect and intercept targets at maximum ranges.
Project LOWER AD
Currently, the most long-range and effective air defense system in the US Army is the Patriot air defense system. This complex is proposed to be supplemented with a new one, so far known as Low-Cost Extended Range Air Defense (LOWER AD). The first mention of this development refers to the fall of last year. Since then, CCDC and related enterprises have managed to carry out part of the necessary work and are now preparing for testing.
The main idea of the LOWER AD project is to create a new simplified and cheaper air defense system, inferior to the Patriot in a number of parameters. A less expensive complex will carry a larger number of missiles with a shorter range. Its task will be to defeat subsonic cruise missiles or attack unmanned systems. More complex targets of other types are proposed to be left for the Patriot air defense system. The combined use of Patriot and LOWER AD is expected to provide an advantageous ratio of combat effectiveness and cost of operation.
Technical details of LOWER AD have not yet been reported, but the main goals of the project, as well as ways to achieve them, have been named. To improve the combat qualities of the air defense system, it is necessary to create a reduced-sized missile defense system, which will increase the portable ammunition load of the launcher. It is required to find the optimal combination of existing and new components. It is planned to use a simpler and cheaper homing head and warheads with the characteristics at the right level.
Possible appearance
Last year, the Pentagon published a presentation on the further development of various tactical missile systems. Together with other developments, this document described a new layered air defense system with six "layers". The slides included images of some components of the LOWER AD air defense system.
The shown self-propelled launcher is made on the basis of a three-axle automobile chassis and is equipped with a lifting device for mounting transport and launch containers. According to various sources, such a launcher will be able to carry up to 25 missiles of a new type. From the point of view of a ready-to-use ammunition load, this LOWER AD variant can become a real champion among modern American air defense systems.
SAM for LOWER AD looks similar to other products in its class. She can get a cylindrical body with a pointed head fairing, on which two sets of planes will be installed. The technical characteristics of the rocket are still unknown. However, it is clear that in some respects it will lose the Patriot missiles.
Apparently, last year's presentation reflected only approximate views of the CCDC on the appearance of a promising air defense system. At that time, the LOWER AD project was under development and it cannot be ruled out that its appearance had not yet been determined. Real samples of new types of equipment may differ markedly from those presented earlier.
Test plan
A few days ago, CCDC announced the completion of part of the design work on LOWER AD. The current state of affairs allows the first tests of air defense systems in a significantly simplified configuration. The first events of this kind may take place in the coming weeks.
The first test launches of the prototype rocket are scheduled for the fourth quarter of fiscal year 4. This means that such tests should take place before the end of September. It is quite possible that an experimental SAM of a simplified design has already been sent to one of the test sites, where tests are being prepared. Carrying out throw launches will allow collecting the necessary data for the further development of the project.
The next year is planned to be spent on further development of the project. Full flight testing will begin in FY2021. Their main goal will be to test the capabilities of missiles to hit air targets of designated classes. The timing of the completion of these activities has not yet been specified. Accordingly, the timing of the adoption of LOWER AD into service remains unknown.
SAM as a solution to problems
Currently, the US Army is armed with several types of anti-aircraft systems that provide a solution to a wide range of tasks. At the same time, the existing air defense has shortcomings and weaknesses. To solve such problems, it is proposed to develop a number of promising samples, incl. using new operating principles.
Weapons based on new principles are proposed to be supplemented with "traditional" missile systems - in this capacity, the LOWER AD product is considered. Its main task will be to help the Patriot complexes in organizing air defense facilities. "Patriot" can hit different targets, but in some cases it is redundant and unnecessarily expensive. It is proposed to transfer targets of this kind to the LOWER AD air defense system with an increased ammunition load of cheaper missiles.
This approach to the development of air defense is of particular interest. The army plans to continue the operation and further development of the Patriot air defense system, but in parallel, new systems of various classes and types will be created. The result of the LOWER AD project should be a noticeable restructuring of air defense, capable of providing a solution to all combat missions with greater flexibility of use. An important factor is the possibility of using effective, but cheaper missiles.
However, the desired savings are very limited. It is proposed not to modernize existing air defense systems with the use of cheaper missiles, but to create a new anti-aircraft system. Thus, the technical and economic conclusions from the simplified rocket are partially offset by the costs of developing and manufacturing all other LOWER AD elements. For what reason they did not begin to create a new missile for existing air defense systems - it is not clear.
The promising LOWER AD project is currently in its early stages. Apparently, the main shape of the future air defense system has been determined and some necessary solutions have been found. In the very near future, the experimental missiles will undergo throw tests, which will allow the design to continue. More serious results will appear only in 2021 or later.
Information on the results of the LOWER AD missile drop tests may appear in the very near future. It will allow you to more fully consider the new project and more accurately predict its future. However, the most complete and accurate conclusions can only be made at the beginning of the twenties - after at least part of the main tests have been carried out and the real qualities of the new air defense system have been determined. Whether LOWER AD can become a solution to the urgent problems of American air defense - time will tell.
