UPDATE: February 15 2017. After Airwars and Foreign Policy revealed that in fact the US has started using Depleted Uranium, I was asked by a couple of people for the full quotes where they pledged not to use it. In the interests of transparency I produce them in full below.
Q1: Given that A10s have carried out around 10 percent of attacks on ISIS so far, can you confirm whether any of them have been equipped with PGU 14 Armor Piercing Incendiary?
A1: CJTF can confirm that the A-10 Thunderbolt II attack jet has been conducting dynamic strikes in support of Operation Inherent Resolve since late November on a regular basis. They are not equipped with PGU 14 Armor Piercing Incendiary.
Q2: The Iraqi government has called for a global ban on the use of Depleted Uranium munitions. Can you explicitly confirm that no DU has been used in any attacks within Iraq and/or Syria during Operation Inherent Resolve?
A2: CJTF can confirm that US. and Coalition aircraft have not been and will not be using depleted uranium munitions in Iraq or Syria during Operation Inherent Resolve.

In recent weeks there has been growing chatter about fears of the potential use of depleted uranium in Syria and Iraq as the Americans and their allies bomb the so-called Islamic State (ISIS).
In particular, an article (Arabic) in the Syrian publication “Raqqa is being slaughtered” recently claimed that residents in the ISIS-run town of Raqqa were fearful that the Americans would use DU as they seek to knock the Islamist militants back.
While potentially effective militarily depleted uranium has long been criticised for being incendiary and having potentially long-term effects on civilians.
The US allegedly used depleted uranium in civilian areas in the 2003 Iraq war in breach of their own protocols. The country has suffered from high rates of birth defects ever since, with allegations that the depleted uranium was to blame.
The only type of plane with the capacity to deploy depleted uranium is the A10. So far, the Americans confirmed, around 10 percent of the strikes carried out have been by A10s – the vast majority in Iraq. But to do so they must be equipped with PGU 14 Armor Piercing Incendiary.
So I asked the U.S. military whether the A10s had been equipped with PGU 14 and whether they would consider using depleted uranium in ‘Operation Inherent Resolve’ – the name for the campaign against ISIS.
John Moore, a captain in the U.S. army and a media relations guy for Operation Inherent Resolve, was unequivocal in his reply.
He said he could confirm 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.”
He also said that none of the A10s had been equipped with PGU 14.
This follows NATO confirming that they did not use DU in Libya. It seems that the pressure by campaigners around use of DU may have convinced militaries to stop its use.
