Pentagon: Used depleted-uranium rounds in ISIS raids
Months after the Pentagon said it wouldn’t use a type of armor-piercing ammunition that has been blamed for long-term health complications, U.S. aircraft fired thousands of the rounds during two high- profile air raids in Syria in November 2015, the Pentagon acknowledged Wednesday.
The use of the ammunition, a 30mm depleted-uranium bullet called PGU-14, was first reported by a joint Air Wars-Foreign Policy investigation Tuesday. The 5,265 rounds of the munition were fired from multiple A-10 ground attack aircraft on Nov. 16, 2015, and Nov. 22, 2015, in airstrikes in Syria’s eastern desert that targeted the Islamic State group’s oil supply during Operation Tidal Wave II, said Maj. Josh Jacques, a U.S. Central Command spokesman.
The strikes, which involved 30mm PGU-14 cannon fire, rockets and guided bombs, destroyed more than 300 vehicles, mostly civilian tanker trucks, the Pentagon said at the time. The two instances were championed by the Pentagon, and footage of trucks being destroyed were posted online.
The Pentagon said no civilians were present during the bombardment because fliers had been dropped before strafing runs warning those in their trucks to flee.
Before the November strikes, the Pentagon said it would not use depleted-uranium munitions in the campaign against the Islamic State, which also is known as ISIS. In response to a query from a reporter in February 2015, Capt. John Moore, a spokesman for the U.S.-led anti-Islamic State coalition in Iraq and Syria said in an email that “U.S. and Coalition aircraft have not been and will not be using depleted uranium munitions in Iraq or Syria during Operation Inherent Resolve.”
Later that year, the Pentagon’s stance toward depleted uranium changed. As U. S.- led forces ramped up their campaign to go after the Islamic State’s cash flow, U.S. planners for Operation Tidal Wave II decided that depleted-uranium ammunition would be the most effective weapon for targeting hundreds of Islamic State oil trucks in the Syrian desert.
Jacques said U.S. forces wanted to ensure that trucks would be rendered inoperable, adding that depleted-uranium rounds were the best way to achieve that, rather than the A-10’s standard high explosive cannon rounds. Typically, depleted-uranium rounds are used on armored vehicles, such as tanks and troop transports, and there is no international treaty or rule that explicitly bans their use.
Depleted uranium is the byproduct of the enriched uranium needed to power nuclear reactors. Depleted uranium is roughly 0.7 percent times as radioactive as natural uranium and its high density makes it ideal for armor-piecing rounds such as the PGU-14 and certain tank shells. Depleted uranium is also used to reinforce certain types of armor and has a number of nonmilitary uses, such as being used for ballast in ships.
In a 2014 United Nations report on depleted-uranium munitions, the International Atomic Energy Agency said “the existence of depleted-uranium residues dispersed in the environment, when observed as confined contamination of soils, vegetables, water and surfaces, does not pose a radiological hazard to the local populations.”
The agency did say, however, that direct contact with larger amounts of depleted uranium through the handling of scrap metal, for instance, could “result in exposures of radiological significance.”
Jacques did not rule out the possibility that the U.S.led coalition might use depleted-uranium rounds again, adding that the locations where it was used in November 2015 have been marked for cleanup in the future. Sanitizing the areas where the ammunition was fired might prove difficult, however, as the area is still primarily controlled by the Islamic State group and whatever scrap left behind from the strikes likely has been recovered and sold.
