Already the U.S. has shipped more than 1.5 million rounds to Ukraine, but Kyiv is still seeking more.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A look at why this particular munition is so commonly used, and why it\u2019s been so critical to <a href=\"https:\/\/www.militarytimes.com\/flashpoints\/ukraine\/\" target=\"_blank\">the war in Ukraine.<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is the 155mm?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Essentially, the 155mm round is a very big bullet, made up of four parts: the detonating fuse, projectile, propellant and primer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Each round is about 2 feet (60 centimeters) long, weighs about 100 pounds (45 kilograms), and is 155mm, or 6.1 inches, in diameter. They are used in howitzer systems, which are towed large guns that are identified by the range of the angle of fire that their barrels can be set to.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The 155mm shells can be configured in many ways: They can be packed with highly explosive material, use precision guided systems, pierce armor or produce high fragmentation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Past variants have included smoke rounds to obscure troop movement and illumination rounds to expose an enemy\u2019s position.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThe 155mm round and the similar Soviet-era 152mm rounds are so popular because they provide a good balance between range and warhead size,\u201d said Ryan Brobst, a research analyst at the Foundation for the Defense of Democracies. \u201cIf you have too small a shell, it won\u2019t do enough damage and go as far. If you have a larger shell, you can\u2019t necessarily fire it as far. This is the most common middle ground, and that\u2019s why it\u2019s so widely used.\u201d<\/p>\n\n\n\t<aside class=\"smg-interstitial-link wp-block-smg-interstitial-link\">\n\t\t<a href=\"https:\/\/one.sightlinemg.com\/defensenews\/video\/2023\/02\/13\/go-inside-the-plant-making-artillery-rounds-for-us-and-ukrainian-armies\/\" class=\"smg-interstitial-link__inner\">\n\t\t\t\t\t\t\t<div class=\"smg-interstitial-link__media\">\n\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"169\" src=\"https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/06\/video-poster-04297762-b2ab-4c03-8b41-8b55b1d02865.png?w=300\" class=\"smg-interstitial-link__image wp-post-image\" alt=\"\" \/>\t\t\t\t<\/div>\n\t\t\t\t\t\t<div class=\"smg-interstitial-link__content\">\n\t\t\t\t<span class=\"smg-interstitial-link__kicker\">Related<\/span>\n\t\t\t\t<h3 class=\"smg-interstitial-link__title\">Go inside the plant making artillery rounds for U.S. and Ukrainian armies<\/h3>\n\t\t\t\t\t\t\t\t\t<p class=\"smg-interstitial-link__excerpt\">Want to see how glowing metal is turned into a lethal artillery shell?

After the war, the new NATO alliance adopted the 155mm as its artillery standard.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">By the Korean War, the round had been modified again, with a cluster munition variant. \u201cThe round contained 88 submunitions, which were dispersed over a wide area to destroy vehicles, equipment, and personnel,\u201d Pleasant said.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Its use in Ukraine<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Howitzer fires can strike targets up to 15 to 20 miles (24 to 32 kilometers) away, depending on what type of round and firing system is used, which makes them highly valued by ground forces to take out enemy targets from a protected distance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cAdversaries don\u2019t have much warning of it coming. And it\u2019s harder to hide from incoming rounds that are arcing in from the top, which makes it highly lethal,\u201d Brobst said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In Ukraine, 155mm rounds are being fired at a rate of 6,000 to 8,000 a day, said Ukrainian parliamentary member Oleksandra Ustinova, who serves on Ukraine\u2019s wartime oversight committee. They are eclipsed by the estimated 40,000 Russian variant howitzer rounds fired at them, she told reporters at a recent Washington event sponsored by the German Marshall Fund.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Pentagon previously had said how many rounds it was providing in each of the security assistance packages being sent about every two weeks to keep weapons and ammunition flowing into Ukraine. But it stopped specifying the number of 155mm rounds shipped in each package in February, citing operational security.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, in its <a href=\"https:\/\/media.defense.gov\/2023\/Apr\/04\/2003192566\/-1\/-1\/1\/UKRAINE-FACT-SHEET-APR-4.PDF\" target=\"_blank\">overall count<\/a> of assistance provided to Ukraine since Russia invaded in February 2022, the Pentagon says it has sent more than 160 155mm howitzers, more than 1.5 million 155mm rounds, more than 6,500 precision-guided 155mm rounds and more than 14,000 155mm Remote Anti-Armor Mine (RAAM) Systems \u2014 essentially a 155mm shell packed with four mines that scatter on the ground and can take out a Russian tank if it drives over them.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Other countries have also provided howitzers, but Kyiv has continually asked for more. As of last year Ukrainian officials were requesting <a href=\"https:\/\/apnews.com\/article\/russia-ukraine-zelenskyy-nato-sergey-lavrov-dd7bc9324e465a15209940c146a859b3\" target=\"_blank\">as many as 1,000 howitzer systems<\/a> to push Russian forces back.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Spring offensive<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">As Ukraine prepares for an intense counteroffensive this spring, it will likely need to fire 7,000 to 9,000 155mm shells a day, said Yehor Cherniev, a member of Ukraine\u2019s parliament who spoke to reporters at the German Marshall Fund event.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In recent months, the Biden administration has been using presidential drawdown authority to send ammunition directly from U.S. military stockpiles to Ukraine, instead of having to wait and buy rounds from defense firms, so they can get there in time for the anticipated Ukrainian counteroffensive.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/www.militarytimes.com\/news\/your-military\/2022\/12\/15\/us-to-begin-training-hundreds-of-ukrainian-troops-every-month\/\" target=\"_blank\">U.S. has also been training Ukrainian troops in Germany<\/a> on how to better use the 155mm rounds in combined arms tactics \u2014 coordinating strikes with targeting information provided by forward-based troops and other armored systems to maximize damage and reduce the number of rounds needed to take out a target.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><i>Associated Press writer Nomaan Merchant
