Reviews of M142 HIMARS and M270 MLRS: the long-awaited dual rocket launcher in Ukraine

 For several weeks now, the names of the American M142 HIMARS and M270 MLRS volley fire systems have repeatedly appeared in statements by Ukrainian officials and representatives of partner countries ready to provide weapons to Ukraine, wrote mezha.media .

First, President Zelensky listed the M142 HIMARS on the list of heavy weapons needed for Ukraine in this new phase of the war, then Deputy Chief of Staff Victoria Nuland mentioned "MLRS, which is already supplied by the United States," and the MOU Intelligence Directorate reported that the Armed Forces were provided by the states. partner country." What kind of magic weapon is this that everyone has been waiting for?

The M142 HIMARS and M270 MLRS are universal MLRS launchers that can use a wide variety of Multi Launch Rocket System Family of Munitions missiles. These include unguided missiles with cluster munitions, mines or "smart bombs", as well as guided cluster munitions, short- and medium-range guided missiles. The pearl of this family is the MGM-140 ATACMS medium-range ballistic missile with a combat radius of 300 km, which can reach frontline airfields and racist depots.

Distinguishing the chassis and novelty of the M270 MLRS and M142 HIMARS. The M270 MLRS was designed in the late 1970s, entered service in 1983 and has a chassis traced from the M2 Bradley BMP. The M142 HIMARS was developed in the second half of the 1990s, and entered the division in 2002. In addition, HIMARS was soon developed as a highly mobile system, the acronym HIMARS stands for High Mobility Artillery Rocket System - a highly mobile artillery missile system. Therefore, the M142 HIMARS is built on the chassis of the M1140 army truck (Austrian Steyr 12M18 modification).

The M270 MLRS carries two universal units on 6 guided missiles / missiles of 227 mm caliber each (or one MGM-140 ATACMS with a diameter of 610 mm); The HIMARS M142 is just one such package. The missile is in an integrated transport and launch case, which is convenient to store, transport and reload. The M270 MLRS can launch 12 package missiles per minute, HIMARS takes half the time. The use of a wheeled chassis, rapid deployment and complex disassembly, digital fire control allow the M142 HIMARS to employ the beat-and-run tactics that the Armed Forces love so much. The M270, which has a crawler chassis, is a little less mobile.

The M142 HIMARS is a fairly new system, so it doesn't require modification, but the M270 MLRS has been upgraded several times. In 2005, the M270A1 received a new fire control system and new mechanical parts of the launcher, which allowed the MLRS to use guided munitions. However the M270C1 generally accepts the fire control system from HIMARS. M270D1 - another update and another in terms of fire control - this time for missiles with GPS guidance, updated computer, display, GPS antenna, remote control system. That is, even the "old" M270 is a very modern weapon.

Depending on the modification of the 227 mm missile, the M270 MLRS and M142 HIMARS systems can hit targets at a distance of 32-70 km, and with the GMLRS-ER long-range missiles even 150 km, it is a pity that these ammunition began to be produced only in 2022.

The MGM-140 ATACMS is a completely different matter, this missile reaches 300 km. The Precision Strike Missile (PrSM) modification is currently being piloted, even at 499 km (instead of 500 km, as this is a violation of the Treaty on the Elimination of Medium-Range and Short-Range Missiles). The ATACMS flies on a ballistic trajectory, rises to an altitude of 50 km, at a speed of 1 km / s (Mach 3), has inertial guidance and GPS. A great addition to our "U-Point", which allows you to direct Russian aircraft from airfields near the Ukrainian border.

It is not known for certain whether the M270 MLRS and M142 HIMARS have arrived in Ukraine, or whether this is just an element of a psychological operation, as the shooters still need to be trained to work with American equipment. But after yesterday's meeting at the Rammstein base, there is no doubt that Ukraine will eventually receive the American MLRS. And this is good.
