The US is expected to include depleted uranium munitions for the first time in a military aid package to Ukraine, which is anticipated to be announced on Wednesday, a US official told CNN.
The munitions can be fired from the US-made Abrams tanks that are set to arrive in Ukraine this fall. The munitions can pierce armored plates like those found on tanks because they are made of a highly dense metal, a byproduct from fuel production for nuclear power plants. Depleted uranium rounds are nearly 70% denser than lead, which is the metal used in standard rounds of ammunition.
The munitions are mildly radioactive, raising questions about their safety and the risk they could pose to civilians — but they have been stripped of most of their radioactive matter and can't produce a nuclear reaction. The US has the munitions stockpiled around the world, a US official told CNN.
The UK defense ministry confirmed in March that it would be sending ammunition containing depleted uranium to Ukraine, which Russian President Vladimir Putin protested. “I would like to note that if all this happens, Russia will have to react accordingly,” he said during a press conference in March. “I mean that the collective West is already starting to use weapons with a nuclear component.” The British ministry said Russia was “deliberately trying to disinform.”
The International Atomic Energy Agency has said that depleted uranium is “considerably less radioactive than natural uranium.” The agency added that the “main conclusion” of studies done on the health of military personnel exposed to depleted uranium is that exposure could not be linked to any statistically significant increases in the personnel’s mortality rates.
Deputy Pentagon press secretary Sabrina Singh told CNN on Wednesday that the US is confident the Ukrainians would use the munitions responsibly if and when they are provided.
“I’m not going to get ahead of any announcements that the Pentagon hasn’t made yet today, but what I will say is these rounds are standard use in the tanks that not only the US uses, but that we will be providing the Ukrainians. And if they are included in the packages that are coming forward today or in the coming weeks, we have absolute confidence that the Ukrainians will use them responsibly as they fight to take back their sovereign territory in the east and the north, as well,” she said.
The move to provide the depleted uranium rounds comes after US President Joe Biden's administration decided to send controversial cluster munitions to Ukraine earlier this year. Both types of ammunition, the US believes, will help the Ukrainians break through Russian defensive lines and pierce Russian tanks amid the ongoing counteroffensive.
