Lockheed Martin delivers first five Sentinel A4 radars to US Army

In the near future, the US Army will begin experimental testing of the new Sentinel A4 radars. The first five radars were delivered by contractor Lockheed Martin at the end of May 2022.

Lockheed Martin calls the delivery of radars an important milestone for strengthening air and missile defense, and these areas are considered by the command of the US Armed Forces as strategic.

Lea Cook, Sentinel Product Director of the Army Sentinel A4 Program Office at Lockheed Martin, said the company is now one step closer to delivering enhanced capabilities to the Army. Earlier it was reported that operational testing of radars will take up to 12 months. The military will test the mobility, performance, environmental impact of radars.

The Sentinel A4 radar is an upgraded version of the earlier A3 radar. The radar is capable of tracking cruise missiles, helicopters and aircraft, artillery and mortar shells, unmanned aerial vehicles. It can track and classify types of threats at the same time.

The Sentinel A4 radar is also known to be combined with the Army's Integrated Air and Missile Defense Combat Control System (IBCS). Its creation is part of the implementation of the plan for multi-domain operations, within which it is necessary to ensure the exchange of data between the platforms of various branches of the American armed forces.

Last year, the Army decided to purchase five more Sentinel A4 radars to send directly to operational units. The company's press release emphasizes that these deliveries are scheduled for March 2023. The contract for the supply of radars was concluded in 2019.

News "nothing". I still didn’t understand what kind of radar this was - what it was intended for, what performance characteristics it had, what was new compared to existing radars. Just a set of stamped phrases.

It’s a secret, it’s normal if the product doesn’t go outside, until, and the adoption by the Pentagon, with a high degree of probability, confirms that the product is working, necessary.
One thing is clear, they are striving to improve the effectiveness of intelligence and other control systems for everything and everything. It is necessary, everyone does it, if possible.

I was not too lazy to go to the Lockheed Martin website and read - although there are mostly advertisements, there is still more information, and the author did not even bother to translate it. No one talked about secret information.

And it says in black and white that this is the country's air defense radar (in our classification), which received the functions of a counter-battery radar (capable of detecting the location of artillery and mortar batteries and rocket launchers). Why it was impossible to add this to the article, I sincerely do not understand.

[Sexton]

Detection range of at least 75 km. It detects everything from UAVs and shells of all MLRS, to shells and mines, missiles and aircraft ... Reception = transmitter based on a cooled AFAR on an external 2-axle trailer. The control point on a car with a 6x6 wheelbase ... The station can be part of a general air defense system or control attached weapons itself ... Judging by the low location of one locator, when used independently, low-flying and inconspicuous targets will be detected at a closer distance. ..

Autonomous operation of the system is provided by an additional power supply station on a skid with a capacity of 10 kW, which is not included in the package?!

AN/MPQ-64A4

I translate: Sentinel A4, in the common people AN / MPQ-64A4, it's almost like AN / MPQ-64A3, but made on the basis of TPS-77 and Q-53 gallium nitride (GaN) technologies☝️
It's the most important.
It can be used as the main airborne target detection station for short and medium range air defense systems, such as Avenger, C-RAM (Phalanx-on-trailer), M-SHORAD, iHAWK latest versions, NASAMS-2), as well as an object air defense radar .
in addition to "classic" air targets (airplanes, helicopters, aviation cruise missiles), it will also be able to detect small-sized UAVs, as well as, like specialized complexes such as AN / TPQ-37 or AN / TPQ-53, unguided missiles of 122 ... 300 mm caliber , artillery shells of 122 and 152 mm caliber, and artillery mines of 60, 82 and 120 mm caliber.
Three-coordinate pulse-Doppler radar AFAR (of course), with a circular view (in azimuth).
Operating frequency band: X (~ 8-12 GHz)
Target detection range: not less than 75 km
The radar station will be equipped with means of identifying "friend or foe" (radar interrogator) and electronic protection (REZ).

Software: based on Mil-COTS (roughly speaking, an open architecture, with military restrictions).
The counter-battery mode (COBRA) has been greatly improved.
Because all available AN / MPQ-64A3 radars can be converted to A4, take all the data on A3 and don’t worry too much

Components:
(1) control and communication vehicle (mobile control center) on a truck chassis (capacity 5 t, 6x6, with armor protection kit) type M1083A1 FMTV
- means of integration (interfaces) into army command and control systems (IBCS system, etc.); means of navigation and geolocation (including the receiving equipment of the SNA GPS / NAVSTAR); means of radio communication; advanced radar control terminal; means of state identification (requestor); target tracking/classification equipment (Composite Tracker & Classifier)
-- power source (electric generator (specific - untranslatable American accent☝️), power not less than 10 kW

(2) radar station (towed by vehicle (1))
-- two-axle trailer M1095 (*) of the FMTV family
-- antenna system (АHEADLIGHTS) + transceiver (receiver + transmitter) + power supply system + cooling system.

*TPS-77 is 3D fno at X frequency), in Russian 3-coordinate, like shampoo, rinse and conditioner on one setting
*Q-53 is counter-battery mode

What are they dreaming about? Happiness happened?

... combined with the army's integrated air defense combat control system
and missile defense (IBCS).

Our detection systems, from drones to radars similar to the "guard" should be built into a single tactical control system "ESU TZ" with a short target designation arm, for example, a commercial drone of the Novorossi militia detected a target - the operator transfers the target to the self-propelled gun battery of the Russian army without unnecessary intermediaries, the target unable to change location.
The problem now, in my opinion, is poor equipment with modern, secure means of communication and a mess, which, I hope, will be eliminated (according to the results of the JI) together with the carriers of this mess.

should be built into a single tactical level control system "ESU TZ"

There is no such system in the Russian Armed Forces and never has been .. There were only Wishlist with unreasonable and changing requirements for a non-working system! Under the guise of preventing a scandal in connection with the failure to implement the president's program from 2000 to 2020 and the loss of allocated funds, the Sozvezdie-M ESU TZ was quickly transformed into a useless Sozvezdie-M automated command and control system (Automated Troop Control System) to automate the exorbitant work of headquarters to collect information about their troops and the transmission of orders to them, in the latter there are no means of reconnaissance and target designation for combat .. No one has seen it either and it is not used anywhere, only for show, like another miracle in the Airborne Forces ACS "Andromeda-D" ...Everywhere there is nonsense and fraud about network-centric systems, because the General Staff of the Russian Armed Forces does not even have the concept of such systems, IN GENERAL ...

[rtv]

In my opinion, this is that "system" at the very beginning of the development of which a large number of Elbrus and Kamaz vehicles were immediately purchased, and a few years later the developers said that they would not be able to develop such a system on Elbrus. Who said cut?

[Volkof]

Once again, how can a system be created if there is no understanding of what it is intended for and what tasks it should perform? There was no technical task, and a civilian concern, collecting information on the Internet, began to create something for the money of the Moscow Region ... Then the military began to formulate requirements that also changed and increased ... It turned out some kind of shit! And for money and terms under Putin's presidential program it was necessary to report! Gerasimov took this shit personally! This circus began in 2014, something somehow worked and was very expensive and useless and allegedly put into service ... Several window dressings using mobile operator stations for communication ... Now they are making ACCS from ESU TZ again and again no one don't know what for! The General Staff of the Air Force still does not have the concept of such systems ... But they are needed yesterday and much easier, and should have been in service for a long time ...Geniuses and luminaries in the General Staff of the Armed Forces of Russia, when will this mess end?

I have no idea. But there was some kind of "system" under which Elbrus and Kamaz were purchased, and then it turned out that it was not possible to implement the "system". And, I remembered, it was the ACS "Perspective", for the air defense of the country. I'm not 100% sure, somewhere around 95%, that it was about "Perspective".

mess, which, I hope, will be eliminated (according to the results of the CO) together with the carriers of this mess.

When the mess is systemic, it reproduces itself, eliminating (in various ways, up to radical ones) its carriers will not help much. However, after three months, even the personalities remained the same. Perhaps everything really goes according to plan.

You hope, but the deadlines for elimination are shifted to the right (not earlier than 2024). I look at some, and I assume that they have dog brains: I understand everything, but I can’t say. At meetings, everything seems to be clear and understandable, but there is not enough mind to formulate the idea ...

Maybe on the contrary, the influence of the environment on the radar. Not?

The United States continuously develops and implements the latest military technologies on land, in the ocean, in the air and in space. Even if only half of American innovations justify themselves, then this is enough for a very serious separation from competitors. At least in the field of intelligence, communications, battlefield automation and information technology. Today, Russia can compete with the United States only in the field of strategic strike weapons. But there is a danger of the appearance in space of American orbital means of intercepting ballistic missiles. And then the US will become virtually invulnerable. Is it necessary to say that Russia and China will perish at the same moment?

Therefore, today it is necessary to seek from the United States an end to the escalation of the arms race. And in doing so, the threat of using the most deadly arguments will have to be used. It's time for us all to realize that if the Americans are not stopped today, it will be too late tomorrow.

Comrade, do all hypersonic missiles fly only along ballistic trajectories?
And what about the "calibers" with special warheads, how? ... It must be so raving in reality ... And about space, it's just insanity ... I wanted to play tricks and so ........

Because of the hatred of such talkers as you, Russia approached all wars extremely unprepared, and therefore each time paid for the victory with millions of lives of its best defenders. It seems that history teaches you nothing.

It doesn't hurt to grab a couple of samples on the Ukrainian front. Arestovich just needs to make a show of hysteria.

The radar is capable of tracking cruise missiles, helicopters and aircraft, artillery and mortar shells, unmanned aerial vehicles.

Station wagon, one replaces several radars.
