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, the RSAF said its KC-135R Stratotanker (foreground), a military aerial refuelling plane, supported the multinational 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.
