At the moment, the US Army and Marine Corps are armed with the ATACMS operational-tactical missile system based on serial MLRS. A long time ago he was recognized as unpromising, as a result of which the development of a new OTRK for replacement was started. With the successful completion of work, rearmament starts by the middle of the decade.

Obsolete Samples

At the moment, the OTRK class in the American army is represented only by the ATACMS (Army Tactical Missile System) family of several major modifications. Products MGM-140, MGM-164 and MGM-168 are single-stage solid-fuel ballistic missiles with a range of up to 300 km and a combat load of several types. Missiles are launched by MLRS M270 MLRS and M142 HIMARS launchers.

OTRK ATACMS was developed in the second half of the eighties, and in 1991 the first MGM-140A missile was put into service. Subsequently, several other ammunition appeared with these or those features. Production continued until 2007. By this time, the customer received approx. 3,7 thousand missiles of four modifications. A substantial part of them was used during exercises and real operations.

Purchases were discontinued due to an unacceptable cost-effectiveness ratio weapons. By 2007, ATACMS rockets were considered obsolete and did not justify acquisition costs. However, the operation continued - the Pentagon planned to spend the accumulated reserves without replenishing them. In the future, the availability of stocks led to the need for modernization of missiles from warehouses.

Plans for the near future are fully related to the ATACMS SLEP (Service Life Extension Program). It provides for the replacement of a number of key components of the rocket in order to extend the life and some increase in combat characteristics. The main goal of the SLEP program is to ensure the operation of cash missiles until the mid-twenties.

In the years 2023-25. A new PTRC is expected to enter the troops, designed to replace the existing ATACMS. For some time, the MGM-140/164/168 missiles will remain in service, but they will be decommissioned as new ones arrive. The whole process can stretch for several years and be completed by 2028-2030.

Perspective development

In 2016, the US Army issued requirements for the promising Long Range Precision Fires (Long Range Precision System) program, which aimed to create a new OTRK to replace ATACMS. Soon Lockheed Martin and Raytheon joined the program. In June 2017, companies received orders for development work worth $ 116 million. In the future, it was planned to compare two projects and choose a more successful one.

At the design stage, the LRPF program changed its name to PrSM (Precision Strike Missile - “High-precision strike missile”). In addition, over time, the tactical and technical requirements have changed. So, initially the maximum range of the new OTRK was limited to 499 km - in accordance with the requirements of the current Treaty on intermediate and shorter-range missiles. After the collapse of the agreement, it became known that the actual range may exceed 550 km; according to some estimates, it will reach 700-750 km. Due to these characteristics, PrSM can move from the operational-tactical category to the short-range missile class.

As with ATACMS, the new missile should be used with standard launchers M270 and M142. At the same time, more stringent dimensions are required. Two missiles should be entered in one standard transport and launch container. Thus, MLRS should carry four PrMS missiles instead of two ATACMS, HIMARS - two new ones.

Initially, flight tests were planned to begin in mid-2019, but these dates have moved. The first launch of an experimental Lockheed Martin development rocket took place on December 10. March 10, 2020 held a second launch; the third is scheduled for May. Lockheed Martin PrSM starts with the M142. A flight range of 240 km was obtained.

A project from Raytheon, codenamed DeepStrike, has run into serious technical problems. The first launch was postponed several times. According to the latest data, it was supposed to take place in the 1st quarter of 2020, but this did not happen.

March 20, it became known that the Pentagon refused to support the PrSM project from Reyteon. Financing of work is terminated, which actually means the closure of the project. The reason for this decision was the failure of the timing of work and the start of testing. All customer attention will now be focused on the Lockheed Martin project.

The future of PrSM

According to earlier plans, in 2019-2020. flight tests of two new missiles were to take place, as a result of which the Pentagon could choose the winner of the program. This would happen at the end of 2020, and soon a contract was expected to be finalized, and then for serial production of new missiles.

Raytheon and its DeepStrike project have virtually dropped out of the PrSM program, which is why its results are now more than predictable. If the army does not dare to close the program for one reason or another, Lockheed-Martin will be the winner with its missile already put out for testing.

The next few years are allocated for the completion of the project. According to current plans, mass production of PrSM starts in 2023. The first rocket battery will reach initial operational readiness in 2025. This will be the first step in a rather lengthy process of transferring rocket artillery to new missile weapons. Will it be possible to fulfill all these plans - time will tell. While the situation as a whole does not favor pessimism.

Likely opponent

The Lockheed Martin PRSM PrSM project provides for the development of a ballistic solid fuel rocket compatible with existing MLRS. In accordance with customer requirements, a two-fold increase in ammunition in comparison with ATACMS.

Declared the possibility of firing at a range of 60 to 499 km. The missile is equipped with controls that provide high accuracy of hitting the target. The modular architecture of the systems should simplify the creation of new modifications and future upgrades. It is possible to carry different types of warheads.

The promising American OTRK compares favorably with its predecessor. In addition, it makes sense to compare it with foreign samples - primarily Russian ones. From the point of view of the tactical role and tasks, PrSM can be considered an analogue of the Russian Iskander OTRK line, and it should be compared precisely with them.

PrSM has some advantages over its foreign counterpart. The first of these is compatibility with existing MLRS launchers, due to which there is no need to create new combat vehicles. Transferring parts to new ammunition will be quick and not too complicated.

In the proposed form, the PrSM product and various Iskander missiles have a range of up to 500 km. In the absence of restrictions on the INF Treaty, American weapons can be upgraded with a noticeable increase in range, which will give it advantages over Russian. However, it is necessary to recall the accusations from the United States regarding the Russian 9M729 missile. It supposedly has a range of more than 500 km (according to various estimates, up to 2-2,5 thousand km). Accordingly, from an American point of view, even after modernization, the PrSM may be inferior to the Iskander missile.

According to well-known data, Lockheed Martin offers a “clean” ballistic missile. As part of the OTRK "Iskander" the so-called quasi-ballistic missile, capable of changing the trajectory and making interception difficult. In addition, the Russian family includes a cruise missile. Such breadth and flexibility of ammunition is an absolute plus, absent in the American project.

The combat qualities of the two complexes as a whole are still extremely difficult to evaluate. The PrSM system is now at the testing stage and has not yet had time to show all its capabilities. In particular, only half of the declared maximum range has been achieved so far. However, new tests are planned, and in the near future, the development of Lockheed Martin will be able to show its best.

Better, but not the best?

According to the results of ongoing work, the US armed forces will receive a new tactical missile capable of replacing a number of obsolete models. It will hit further and more accurately, and standard launchers will be able to carry twice as much ammunition. Thus, the ongoing work will have obvious positive consequences for the combat effectiveness of the army.

However, against the background of advanced foreign systems of its class PTRK, PrSM looks ambiguous. Over the past years, progress in this area has managed to go forward, as a result of which the new American complex is at a disadvantage. Will we be able to cope with the existing lag and surpass competitors - we will find out later.

    The author's passage about "... in the proposed form the PrSM product and various missiles of the Iskander family have a range of up to 500 km. In the absence of INF restrictions, American weapons can be upgraded with a noticeable increase in range, which will give it advantages over the Russian."

    The Russian Iskander was created on the basis of the Soviet Oka OTR. In the USSR, there was a project for the development of a two-stage MRBM Volga based on the Oka (the design documentation for which was not destroyed). In addition, the 450-kg conventional Iskander warhead can be replaced at any time by a 130-kg nuclear warhead with a TNT equivalent of 250 Kt and a range of +1000 km.

      Read nuclear warhead treaties.
      Read about the places (bases) of storage of nuclear warheads.
      About the minimum distance of the places (bases) of storage of nuclear warheads from the places of deployment of carriers of nuclear warheads.
      About the warning system of all parties to the treaties when working with nuclear warheads.
      And so on.
      And if you read it, you will understand the nonsense that you write about "can be replaced at any time" ...

        You just wrote nonsense ... the treaties regarding control over nuclear weapons relate exclusively to strategic nuclear forces, nuclear weapons of both parties were not even considered and it is not really known how much we have .... or 10 or 15 times more than in the USA. ... the actually overwhelming quantitative superiority in the quantity and quality of carriers is our trump card in the confrontation with NATO ...

      Worse is another: some people believe that such tricks can bring victory in a nuclear war!
      And they will bring only complete and final defeat.

        For questions of faith, you can contact the nearest church. And Russia in the global nuclear conflict is intensely preparing not only to survive, but also to win. The main thing is to delay this moment until 2025-2030

          The peak of preparation and "delaying" through a frenzied arms race in the USSR Russia had already taken place by the summer of 41. The result was the largest military catastrophe of the Red Army in world history, which, of course, became a "great victory." Since the catastrophe remained unpunished for the "organizers of our victories", and the lesson was not for the future, it is quite possible to expect a repetition of the unlearned in the 21st century. 27 million killed in a war against a relatively weak enemy - a "great victory"? Now, in the war against the strongest military-political blocs in the world - it will be even more "great" ... Prepare a festive fireworks.

            The result was a red banner with a sickle and a hammer over the Reichstag and the largest catastrophe in the world history of the Wehrmacht, bg-g-d.
            the strongest military-political blocs of the world

            Are you talking about NATO now, which is empty space without the USA, lol?
            lesson - did not go to anyone for the future

            You can also add about hatred and puten off the coils of Puten. Turn over the page, what's next in your oh training manual?

      In the INF Treaty it is cunningly written about the tested range .... The Iskanders (both) honestly did not experience more than 490 km :)))

    We also need what is easier than Iskander and cheaper ... In addition. On the Kamaz chassis, for example, and with a caliber of 300-400mm
    1. aristok
      aristok April 1 2020 13: 12 New
      on the chassis of Kamaz and Iskander will fit 1 pc.
      Initially, I don’t understand why it was necessary to fence an expensive and bulky carrier for 2 pcs.

      The same with Smerch (Tornado-s).
      300 mm deserve a manageable version as the main one.
      And you can get by with carriers for 2-6 rockets without building expensive monsters for 12 pcs.

        I'm talking about a simpler and more accurate missile ... like "Smerch" 300mm corrected. Moreover, there is a PU Typhoon 8x8 with 6 pieces of guides

    A huge plus for the Americans is the use of so many rockets from a conventional at first glance MLRS. We would not be hurt by something like this. Based on Tornado for example.

      The Americans initially made a modular MLRS system with a batch change of module-packages.
      We initially have a different system. Not modular.

      Accordingly, nothing "additional" can be done on the basis of the Tornado.
      There is of course a version of Hurricane-1M,
      In extremely small quantities delivered to our troops.
      But it will be an analogue of HIMARS in combat load.
      It is necessary to completely create a new modular MLRS with large ammunition from scratch.
      And of course, make universal modules of all possible variations.
