How ATACMS to help Ukraine Analysis by Kyiv Post

Kyiv Post has published an article claiming that a guide to the powerful Army Tactical Missile Missile Systems (ATACMS) which, recent news reports in the US suggest, might be soon on its way to Ukraine. Caliber.Az reprints the article.

The US media site ABC News quotes a US official saying, in relation to ATACMS, that “They are coming,” while at the same time hedging his bets by noting that, as always, such plans are subject to change until officially announced.

A second official said the missiles are “on the table” to be included in the next US military security assistance package for Ukraine, although a final decision has not been made. 

If they do come, ATACMS will potentially play a significant role in destroying Russian materiel and personnel and important command centres as well as in interdicting enemy logistics. 

Designed to destroy targets at ranges up to 300 km, these missiles could effectively target Russian military facilities in occupied Crimea and the high-profile Kerch Bridge. That is assuming the US would not place restrictions on their use against legitimate targets located on Ukrainian territory.  

It is possible that, as with F-16 fighter aircraft, the US might impose restrictions on the use of ATACMS against enemy forces located on.

What is ATACMS?

ATACMS (pronounced “attack’ems”) is a tactical ballistic missile manufactured by the US defence company Lockheed Martin. Development of the missile started in 1980, based on a US requirement for a long-range, non-nuclear capability to strike enemy rear-area logistic and reserve positions.

It has a solid propellant motor which gives it a range of up to 300 km. The missile is 4 meters high and 610 millimetres in diameter. 

It can be fired from the tracked M270 Multiple Launch Rocket System (MLRS), and the M142 High Mobility Artillery Rocket System (HIMARS), both of which are in use with the Armed Forces of Ukraine (AFU).

To date, there have been five variants of the missile produced:

• M39 cluster munition – inertially guided, carrying 950 M74 anti-personnel and anti‑materiel sub-munitions with a range of 25-165 km. Production ceased in 1997; total produced: 1,650;
• M39A1 – GPS-aided guidance added, the size of the engine increased resulting in the reduced payload of 300 M74 APAM sub-munitions but the maximum range increased to 300 km. Production ceased in 2003; total produced: 610;
• M48 – GPS-aided guidance fit with 230-kilogram WAU-23/B penetrating high-explosive blast fragmentation warhead (same as US Navy Harpoon anti-ship missile), maximum range 300 km. Production 2001-2004; total produced: 176;
• M57 – improved version of M48 with greater accuracy: Circular Error Probability (CEP) of 9 meters. Production 2004-2013, total produced 513;
• The M57E1 – upgraded M39 and M39A1 with improved motor, updated navigation and guidance software and hardware giving a CEP of 3 meters. It is fitted with the WAU-23/B warhead section instead of the M74 APAM sub-munitions with a proximity sensor for airburst detonation. Production commenced in 2017 with a total assessed quantity produced of 1,200.

Once delivered to Ukraine, the missiles will quadruple the 70 range of the current M142 HIMARS and M270 MLRS platforms, which have already become game changers.

Using the current weapons, the AFU has destroyed a number of enemy ammunition dumps and command centres along with hundreds of armoured vehicles, artillery, antiaircraft systems and radar stations and their crews. 

ATACMS will give Ukrainian forces the ability to destroy such targets far deeper into the enemy's rear.

In 2022, the average price of one ATACMS missile was approximately $1.5 million.

History

The XMGM-140A missile was first test-launched in 1986. In 1991, the modified MGM-140 was officially commissioned for use by the US Army with shortly afterwards, 32 of the missiles being used during Desert Storm against Iraqi facilities. Their effectiveness was assessed as very high.

A series of upgrades that followed, one of which being GPS guidance added to the inertial targeting system, significantly increased the speed, range and precision of the ATACMS. In 2003, Operation Iraqi Freedom saw the launch of more than 450 ATACMS missiles.

The Iraqi army's outdated air defences were simply unable to defend its important facilities, communications hubs and command centres against the American missiles that flew at a formidable speed of 5,000 kmph.

Work began on an ATACMS replacement in 2016, which became the Precision Strike Missile (PrSM) program in 2019, with a planned in-service date of 2023. PrSM, as currently envisaged will be fired from the same M270 MLRS and M142 HIMARS launchers with a range in excess of 500 kilometers.

Why does Ukraine need ATACMS?

While many Russian military bases, logistics facilities and other targets in Crimea are out of reach of Ukraine's HIMARS rockets, ATACMS would effectively overcome this shortcoming. In particular, they could neutralize the Russian ballistic missile complexes that frequently bombard Odesa.  

ATACMS is a high-speed ballistic missile that climbs as high as 50,000 m, changes trajectory in flight and accelerates up to Mach 3 making it extremely difficult to intercept.

The short-term provision of even a small number of ATACMS could radically change the situation because they can interdict Russia's key supply routes that run very far from the frontlines.

By destroying bridges and railroad facilities they would significantly debilitate the Russian forces. The loss of missile and radar complexes in the occupied territories would mean they could no longer terrorize Ukrainian cities.
