War analysts argue the West needs to break the supply chains keeping Russia's deadliest guns firing before it's too late

• Russia has an edge over Ukraine when it comes to artillery — which is still king.
• A new analysis identified several ways that the West can disrupt Russia's artillery supply chain.
• Analysts said the West needs to go after Russia's foreign imports before it's too late.

More than two-and-a-half years into the brutal, high-casualty war in Ukraine, artillery shells and the howitzer cannons that fire them continue to be among the more devastating weapons on the battlefield.

Despite international sanctions meant to cripple Russia's war machine, Russia has maintained an edge over Ukraine when it comes to artillery production and rate of fire.

Over a dozen analysts from the Royal United Services Institute wrote in a new report that Russia's artillery advantage "is the single greatest determinant of the distribution of casualties and equipment loss, the balance of military initiative, the calculus of what is operationally possible, and thus the political perception of the trajectory of Russia's full-scale invasion of Ukraine."

Russian artillery is estimated to be responsible for more than 70 percent of Ukraine's combat casualties.

The analysts at RUSI said that the West needs to disrupt the industries that are keeping Russia's deadly and destructive howitzers firing before it's too late for Ukraine.

Russia's defense industry is growing through new facilities, supply imports, and mass recruitment, the analysts said. They said that, without interruption, Moscow will be better poised to strengthen its position in Ukraine within the next few years.

The report explained that "Russia is self-sufficient in many of its needs, especially in raw materials like iron ore, and may have enough machine tools and stored howitzers from the Soviet era to support its war in Ukraine."

However, the analysts said, "the longer the war continues, the more Russia's dependencies on foreign suppliers will become a weakness."

It is difficult for Western countries to target the supply chain inside Russia because there are elements in place that can shield companies from measures like international sanctions, but the analysts identified several vulnerabilities in the process of importing foreign materials before they reach the country.

These vulnerabilities include placing sanctions on the supply of essential materials to Russia, preemptive purchasing of raw materials on the open market to prevent them from falling into the hands of hostile nations, or putting diplomatic pressure on countries to examine their domestic companies that are exporting goods to Russia.

One example the RUSI report gave was targeting chrome ore imports for barrel production. Another involved hindering the flow of machining equipment into Russia.

The analysts said that Ukraine's Western partners should immediately prioritize disrupting Russia's artillery supply chain because doing so for prolonged periods will make it more difficult for Moscow to maintain its howitzers and artillery ammunition.

This is critical for Ukraine. The analysts warned that "left on its current trajectory, Russian fire superiority will increase year-on-year and become less vulnerable to external disruption through pressure on the supply chain."

The task potentially becomes even more urgent for the West as Russia continues to increase its security ties with China, Iran, and North Korea. The US has publicly expressed concern over Moscow's deepening military relationships with its rivals and foes over the past few years.

Ukraine has managed to reduce Russia's long-held artillery advantage and is increasingly taking steps to degrade its stockpiles of shells by using long-range drones to attack ammunition depots inside Russia, but more is needed to break Russia's edge.
