Panic in the USA in connection with the fiasco of the Patriots led to an unexpected result. LTAMDS Project

32
It is no secret to anyone that the successful launch by Ansar Allah missile units of a massive missile attack on the key Arabian oil refinery in Abkayk and the Khurais oil production complex in September 2019 provoked frankly panicky sentiments among specialists of the US defense department and Industrial Corporation Raytheon.





It’s hardly worth showing any bit of surprise here, because literally overnight the prestige of the largest American manufacturer of advanced air defense systems and precision weapons, as well as a debilitating blow to the competitiveness of its main offspring - the multi-channel anti-aircraft missile / anti-missile systems "Patriot PAC-2 / GEM-T" and "Patriot PAC-3MSE". More than a dozen divisions of these air defense systems that September night did not even bother to partially cover the head infrastructure of the Arabian oil company "Saudi Arabian Oil Company" from the Houthis drones-kamikaze "Samad-1/3" and tactical long-range cruise missiles "Quds-1".

As you know, the low altitude flight paths of the latter left no chance for the multifunction radar AN / MPQ-53 and AN / MPQ-65 for the timely detection, stable linking of the tracks of attacking missiles, as well as for the illumination of anti-aircraft missiles MIM-104C / E GEM-T and target designation of promising MIM-104F PAC-3MSE missiles.

Failure after failure. Outdated "hardware" of AN / MPQ-53 / 65 radars makes itself felt


In our previous reviews, starting from the data published in the western and Russian segments of the Internet, we were able to accurately determine the “etiology of the genetic disease” of the AN / MPQ-53 / 65 family of multifunctional radars, which led to the failure of the Arabian Patriots.

It is connected, firstly, with a minimum beam elevation angle of the order of 1 degrees (the lower limit of the elevation viewing area for a given radar family), while, for example, the minimum beam elevation angle of a radar for target illumination of 9X36 Buk- M2 ”has a negative value of -5 degrees. It is logical to assume that this MPQ-53 / 65 radar index limits the minimum height of 30 meters to be detected, tracked and “captured” by targets, while the “Bukovsky” 9С36 radar operates on low-altitude targets operating in the range from 10 to 15 meters. Obviously, the trajectories of drones and cruise missiles launched by Husitian rocket-propelled gunners could have passed at “unseen” MPQ-53 / 65 radars at heights of 15-25 m, which no longer allowed the “Patriot” MIM-104F PAC-3MSE anti-ballistic missiles to successfully Aircraft AWACS E-3A Royal Saudi Air Force. As you know, at that time in the Arabian airspace aircraft of this type did not carry out combat duty.

Secondly, the AN / MPQ-53 / 65 family of radars do not have the ability to operate in a continuous all-angle scanning mode of aerospace with azimuthal coverage of 360 degrees. This drawback is observed in connection with the placement of the antenna array of the passive headlamp on a sedentary hardware container, the turn of which towards the new missile-hazardous sector is extremely slow, and even then at the time of the “time window” between the enemy’s massive missile attacks.

It is quite obvious that this state of affairs, especially against the background of the active improvement of low-altitude air attack systems of the enemy with low ESR, could not suit either Pentagon specialists and US ground forces, or the Raytheon corporation headquarters, whose missile defense rating over the past month was relegated to the level of "border".

Features of the LTAMDS project. Pentagon brainchild of Raytheon


A partial way out of this situation was a curtly designed project for the promising multi-functional AFAR-X / Ku-band radar LTAMDS (Lower Tier Air and Missile Defense Sensor) designed to re-equip existing Patriot PAC-2 / 3MSE anti-aircraft missile divisions having obsolete MPQ-53 / 65 stations with passive headlights.



After reviewing the full-size LTAMDS prototype presented at the AUSA-2019 US Army Association exhibition, you can pay attention to the full modular architecture of the new product. As you can see, to power the high-energy microwave gallium nitride PPM main antenna post and additional AFAR modules for viewing the side and back hemispheres, it was necessary to equip the platform with powerful power centers with 24 cooling coolers. Undoubtedly, the detection range of small targets with an EPR of the order of 0,01 sq. m through the main antenna post can increase to 90 — 100 km in comparison with 45 — 50 km for MPQ-65.

Moreover, the use of individual low-noise microwave transistors based on semiconductor gallium nitride in the transmitting and transmitting modules will allow expanding the radiation pattern in the lower sector by reducing the elevation angle of the beam of the new station to -3 / -5 degrees, which will allow to detect and effectively track targets at altitudes 3 — 5 m. According to this indicator, LTAMDS will be compared with domestic radars 9С36 of Buk-M2 systems, and possibly unique low-altitude detectors Podlet-K1, adapted for operation with goals, loitering over mountainous terrain with belittling of several hundred meters. Equipping two additional stationary AFAR modules with a total azimuthal viewing sector of about 200 degrees will provide the new LTAMDS station with the ability to view the entire airspace without any delay in the rate of updating radar information, which is observed with a low-altitude detector such as Podlet-K1 or a centimeter high 96L6 detector, which is part of the S-400 Triumph air defense system.

Meanwhile, a noticeably smaller area of ​​antenna canvases (and, therefore, a lower energy potential) of additional radar modules of the LTAMDS station will still limit the detection range of small targets approaching LTAMDS from the rear hemisphere, which cannot be said about the Russian Vityaz 50Н6A multifunctional radar. Moreover, the LTAMDS concept still does not provide for the placement of antenna posts on a universal tower, which indicates a small radio horizon of the promising “Patriot” radar, reaching only 25 — 29 km, which is one and a half times less than Russian illumination radars 30Н6Е / 92Н6Е included in the structure of complexes C-300ПМ1 and С-400 "Triumph".

          For manipulation, they take constantly decreasing periods of time, while the moment in time when the turtle is caught is artificially taken out of consideration.

        Radio engineering is a key discipline in air defense systems, and Russia since the time of Alexander Sergeyevich Popov, the inventor of radio, has always been, is and will be an advanced radio engineering power.
        The United States uses the best practices and brains of Russian scientists, be it Ufimtsev in matters of "stealth", Zvorykin in television, Kotelnikov in optimal radio reception ... Bonch-Bruevich and Mints in powerful radio transmitters ....

      The mistake is that with a negative angle of the beam, the detection height will also be negative.

    As it became known, not the Patriot, but the Swiss Skyguard air defense system was responsible for the air defense of the oil complex at low altitudes. Patriot for medium and large heights.

      You would have looked at least with one eye what modifications are and what they are responsible for, and not bravado arranged:

      The modification of the Patriot PAC-1 air defense system (Patriot Advanced Capability, "Patriot" with promising capabilities) increased the effectiveness of the destruction of the tactical ballistic missile (TBR) systems. The software of the complex was first of all improved, and the radar scanning angles were also increased.

      SAM Patriot PAC ‑ 2 is designed to provide cover for small areas from tactical ballistic missile attacks. The air defense system not only deflects missiles from the target, but also completely eliminates them. During the upgrade, changes were made to the software, the warhead of the rocket, which received a new fuse, and the striking elements of increased mass were improved (the mass of fragments was increased from 2 to 45 grams).

      As part of the second phase of the modernization of PAC-2, a missile was developed that has an improved targeting system, including an improved radio fuse.

      At the same time, radar software was finalized to improve the ability to intercept tactical ballistic missiles. During the modernization, according to experts, they managed to increase the area defended by the Patriot air defense system from the TBR four times.

      The Patriot PAC-3 air defense system is designed to intercept the warheads of tactical ballistic and cruise missiles, including those made using stealth technology (reduced signature).

      The complex uses a highly maneuverable direct hit missile ERINT (Extended Range Interceptor). It is a single-stage solid-fuel projectile made according to the normal aerodynamic design with wings of small elongation and aerodynamic rudders-ailerons.

    I am, of course, not air defense. But. If we are building a defense, then we need echelons: Someone is beating the enemy on the distant lines, someone is directly at the trench, someone is silently sitting behind, to help the trench. The Patriots are not to blame, they are not sharpened for that. There is no defense system. And it won't. I'm not familiar with: "Air raid". At least our grandfathers could tell our engineers what it is.
