DONETSK REGION, Ukraine — Nearly four months after Russia invaded, the Ukrainian military is running low on ammunition for its Soviet-era artillery and has not received enough supplies from its allies to keep the Russians at bay, Ukrainian officials and artillery officers in the field say.
The shortage has put Ukrainian troops at a growing disadvantage in the artillery-driven war of attrition in the country’s east, with Russia’s batteries now firing several times as many rounds as Ukraine’s. While the West is sending in weapons, they are not arriving fast enough or in sufficient numbers to make up for Ukraine’s dwindling arsenal.
The Western weapons, heavy, long-range artillery pieces and multiple-launch rocket systems, are more accurate and highly mobile, but it takes time to deploy them and train soldiers to use them. In the meantime, Ukraine is running out of ammunition for the older weapons.
On the front lines in Donbas, Ukrainian soldiers are being forced to conserve shells, and are often unable to return fire one for one.
At one Ukrainian artillery position on Friday, several Russian shells had just sailed overhead, landing in a field with methodic thuds, when the gun’s crew was told to get ready to fire. Their drones had spotted a group of Russian howitzers a few miles away.
The soldiers scrambled, pulling branches from their 122-millimeter self-propelled gun camouflaged on the edge of a wooded area. The barrel angled skyward before firing only two shots, sending dirt and leaves into the air.
A few weeks ago, the gun would have been firing constantly, its crew said. Now, instead of blanketing Russian positions with ordnance, they can engage only specific targets, like the Russian howitzers.
“We’re running out of shells,” said Oleg, one of the soldiers in the crew, clad in dirty trousers and skateboard sneakers. “They are not supplied fast enough since we fire too often.”
Mariana Bezugla, a member of Ukraine’s Parliament who is the deputy head of the National Security, Defense and Intelligence Committee, said similar shortages of ammunition for Soviet-era weapons were occurring throughout the eastern theater, where Ukrainian forces have been battling to hold the resource-rich Donbas, which comprises the Luhansk and Donetsk regions.
“They have a lot of resources, a lot of ammunition,” Ms. Bezugla said of the Russians. “It is not comparable with ours.”
Ms. Bezugla said that Ukraine has received plenty of ammunition for its new NATO artillery pieces, it still does not have enough of those weapons to replace the older equipment. “We have munitions of the new type, but we still lack guns” to fire them, she said.
Pentagon officials say that they have exhausted all efforts to scrounge up available Soviet and Russian weaponry and munitions for Ukrainian troops to use, after months of horse-trading with allies who were still using the old systems. A senior American military official acknowledged that the well had run dry, and said that Ukraine would likely need to depend on Western munitions systems to defend against Russia in the East.
But that means speeding up training of Ukrainian troops on the new systems, the official said, which can take some time. Pentagon officials have sharply condensed the time for Ukrainian troops to train, compared to what American troops spend before being declared proficient on some of the weapons systems.
On Friday, Ukraine’s deputy head of military intelligence, Vadym Skibitsky, told The Guardian newspaper that Ukraine was losing the artillery battle with Russia on the front lines because of the shortage of artillery shells for its older guns. He said Ukraine was firing 5,000 to 6,000 artillery rounds a day and had “almost used up all of our ammunition.”
By contrast, Russian forces are firing about 60,000 artillery shells and rockets each day in the Donbas fighting, according to a senior adviser to the Ukrainian military command who was not authorized to speak publicly.
Michael Kofman, the director of Russia studies at CNA, a research institute in Arlington, Va., said ammunition supplies would be critical to the final outcome in the battle for eastern Ukraine.
“This war is far more about attrition by artillery than maneuver, which means one of the deciding factors is who has more ammunition,” he said.
That Ukraine was running low on ammunition has hardly been a secret. Ukrainian officials flagged the problem months ago. On the front lines, commanders watched, alarmed, as stocks dwindled mid-battle. Soldiers say requests for artillery support go unanswered, for lack of shells.
Vadym Mischuk, 32, a Ukrainian soldier who had just rotated off the frontline near the eastern city of Bakhmut, said Thursday that there is so much Russian artillery fire that “we don’t even hear ours.” One soldier, who declined to provide his name for security reasons, estimated that for every one Ukrainian shell fired, the Russians fired 10.
The Ukrainian military has been honest about the shortfalls — something an army would not typically telegraph to the enemy in a war — perhaps because doing so adds a sense of urgency to appeals for more powerful Western weaponry.
“In early March we were already well aware that during intensive war with Russia our resources were depleting,” Ukraine’s defense minister, Oleksiy Reznikov, wrote on Facebook on Thursday. He added, “Relying solely on Soviet weapons was definitely a losing strategy.”
Even before the invasion, Ukraine’s ammunition depots had been targets for saboteurs, regularly blowing up like gigantic, lethally dangerous fireworks displays.
Russia-Ukraine War: Key Developments
In eastern Ukraine. As vicious street-by-street combat continues in the city of Sievierodonetsk, President Volodymyr Zelensky and other Ukrainian leaders are stepping up their pleas for the quick delivery of heavy weapons to help them. Last week, Ukrainian forces appeared to withdraw from Sievierodonetsk, only to later mount a counterattack.
E.U. membership for Ukraine. The European Parliament recommended that Ukraine be granted candidate status for membership in the European Union. The E.U.’s decision on Ukraine’s candidacy, which is expected in late June, will put to the test the bloc as it tries to figure out ways to bind vulnerable countries like Ukraine, Moldova and Georgia to Europe without creating security risks.
Prisoners of war. Russian investigators said they had opened more than 1,100 cases into “crimes against peace” committed by the Ukrainian government, paving the way for what could turn into a mass show trial of hundreds of Ukrainian service members. Two Britons and a Moroccan who had fought for the Ukrainian armed forces, meanwhile, were sentenced to death by a court in Russia-occupied eastern Ukraine after being accused of being mercenaries.
Power consolidation. As Russia continues to pound towns and villages across eastern Ukraine, the Kremlin is trying to deepen its hold on occupied territory in the south, restoring rail links and other key infrastructure to secure a “land bridge” from Russia to the Crimean Peninsula.
Spies or drones dropping incendiary devices were blamed in many cases. Between 2015 and 2019, six ammunition depots blew up in Ukraine, burning about 210,000 tons of ammo, or three times more than the Ukrainian army expended in the same time span fighting Russian-backed separatists, according to Radio Free Europe/Radio Liberty.
Following Russia’s invasion, NATO countries have stepped in to bolster Ukraine’s supply of ammunition, but the transfers have not always gone smoothly. Countries of the old Warsaw Pact and NATO countries used different calibers of ammunition — an enduring legacy that means much of Ukraine’s arsenal, built decades ago to Soviet specifications, cannot fire Western ammunition.
Ukraine’s newly acquired hoard of NATO’s 155-millimeter artillery shells is now larger than its entire artillery ammunition stockpile before the war started, Mr. Reznikov said. But the Ukrainian forces have too few guns at the front to fire the munitions, and are facing extensive logistics challenges not only to get them into the fight, but also to maintain them once there.
Some European countries have shipped so many of their own ammunition reserves to Ukraine — in some cases up to 30 percent — that they’re increasingly anxious about replenishing their stocks, European Union officials said.
Officials said that while there was still a relatively steady flow of military equipment from the E.U. and its allies, Ukraine was not receiving as much heavy artillery as it needs.
With artillery shells in short supply, Ukrainian forces have adjusted their tactics to compensate for the lack of artillery support. On Friday, for example, a tank unit in Donbas was using a Ukrainian T-64BV tank more like an artillery piece than a main battle tank.
Instead of attacking targets directly, the tank drove several kilometers toward the front, positioned itself in a tree line, and lobbed shells at Russian positions while a Ukrainian officer adjusted its aim over the radio and using a drone head overhead — the procedure typically used with mortars or howitzers.
“It is a fact already that the tanks are used because there is not enough artillery,” said the artillery unit commander, who asked to go by his nom de guerre, Razor. His unit of 122-millimeter, self-propelled howitzers had run out of Ukrainian ammunition and was now using Czech-supplied shells.
But ammunition can be fickle. Decades-old ammunition can become unreliable if not stored properly over time, potentially leading to more duds. Another soldier, who spoke on the condition of anonymity, said that a batch of Czech-supplied rockets were faulty, with only three out of 40 firing.
Ukrainian soldiers wounded in combat have also voiced dismay about the paltry artillery support, which they blamed on a lack of ammunition.
“There is not an hour with a pause” in Russian bombardments, Lt. Oleksandr Kolesnikov, who was wounded late last month, said in an interview in an ambulance while being evacuated to a hospital to the west. “The artillery is very intense.” He said his commander called in artillery in response but received only one salvo.
The Russian artillery superiority has frightened soldiers, he said. “In war, everything is scary and we fear everything. Only idiots are not afraid.”
