SINGAPORE - The Republic of Singapore Air Force (RSAF) has completed a three-month deployment to the Middle East to support the fight against the Islamic State in Iraq and Syria (ISIS).

In a Facebook post on Sunday (Sept 3) evening, the RSAF said its KC-135R Stratotanker, a military aerial refuelling aircraft, supported the multi-national coalition against the extremist threat, including during the fights for Mosul in Iraq and Raqqa in Syria.

It performed over 50 missions, refuelling the coalition aircraft in the US Air Force Central Command's area of responsibility.

It was the third time the KC-135R Stratotanker had been deployed since 2015.

Lieutenant-General Jeffrey Harrigian, Commander of the US Air Force Central Command and Combined Forces Air Component Commander to the US Central Command and Combined Joint Task Force for Operation Inherent Resolve, commended the RSAF's contribution to the cause.

"Singapore's KC-135R helped fuel the fight and strengthen the blows we directed at ISIS over this summer. I am thankful for their continued commitment to support the fight to defeat a global threat like ISIS and bring stability to the region," he said.
