Singapore dispatched a troop landing ship with a crew of 180 to Iraq on Saturday.
The ship Resolution will stay in the Persian Gulf three months, the city-state’s Defense Ministry said.
The crew’s mission is to monitor the waters around key oil terminals, provide logistical support for coalition vessels and helicopters, and conduct patrols and boarding operations, the statement said.
The wealthy Southeast Asian island has been a staunch supporter of the U.S.-led effort in Iraq.
Singapore earlier deployed another troop landing ship, a C-130 transport plane and a KC-135 tanker aircraft to the gulf to aid the Iraq reconstruction effort. It also sent 32 police officers to Baghdad in July for two months to train Iraqi police.
