The NATO ally Turkey began sending the first batches of so-called dual-purpose improved conventional munitions (DPICMs) in November 2022, which were made during the Cold War era under a co-production agreement with the United States. The weapons are designed to destroy tanks by bursting into smaller submunitions, which can linger on the battlefield for years if they do not immediately explode. Each round scatters about 88 bomblets. The United States is barred from exporting DPICMs under U.S. law because of its high dud rate, according to the Foreign Policy.

Foreign Policy wrote that the move, which Turkey has sought to keep quiet for months, also highlights the high-wire act that Ankara has played throughout the conflict: supporting Ukraine with armed Bayraktar TB2 drones that helped break Russia’s advance on Kyiv and playing diplomatic middleman for the United Nations-brokered deal to export grain from the Ukrainian port of Odesa, all while purchasing Russian weapons for itself and angering NATO in the process. It was not immediately clear if the Turkish surface-to-surface weapons had been used in combat. 

“After the U.S. denied [Ukraine] access to cluster munitions, Turkey was the only place they could get them,” one source briefed on the matter, who spoke on condition of anonymity told Foreign Policy. “It just shows how even as Turkey cozies up to Russia in some respects, it’s become a really important supporter for Ukraine militarily.”

Neither the Turkish Embassy in Washington nor the Ukrainian defense ministry responded to Foreign Policy’s request for comment.

Foreign Policy highlights that Turkey’s delivery of DPICMs showcases how Ankara has played an outsized role in supplying weapons to Ukraine to break Russia’s full-scale invasion at critical moments in the war since Russian President Vladimir Putin ordered the assault in February 2022. 

“The Turkish-made Bayraktar TB2 drones helped halt Russian armored convoys converging on Kyiv in the early days of the war, and they reportedly had a role in assisting Ukraine’s sinking of the Russian cruiser Moskva, then the flagship of the Black Sea fleet. Turkish analysts also believe that Turkey is quietly running a drone bridge from Corlu air base near the Bayraktar TB2 factory, where weapons are shipped to Poland and moved to Ukraine. And Turkey has walked a tight line on weapons deliveries: Even as Turkish President Recep Tayyip Erdogan and his brass in Ankara have tried to keep them quiet, some of their close confidantes—including the president’s son-in-law, who is chair of the board of the company that manufactures Bayraktar TB2s—have openly championed the drone’s prowess on the battlefield,” Foreign Policy reported.

Although Turkey has not shared information on the quantities of cluster munitions in its stockpile, the Ankara-based Mechanical and Chemical Industry Corporation has produced an extended-range artillery projectile in the past that can be fired out of 155 mm cannons with self-destructing DPICM submunitions as well as similar projectiles that are under license from the United States. Roketsan, another major Turkish weapons producer, once made TRK-122 rockets for 122 mm artillery systems that also scatter DPICM submunitions. Slovakia, Chile, and the United States have transferred cluster munitions to Turkey in the past, according to Foreign Policy.

“But the move still is a reversal of sorts for Turkey, after it made pledges to the international disarmament community that it would not use cluster munitions. In a letter sent to the president of the Convention on Cluster Munitions, a Geneva-based international organization, in October 2021 and obtained by Foreign Policy, Turkey insisted that it had not used, produced, imported, or transferred cluster munitions since 2005—when the convention was implemented—and did not intend to do so in the future.”
