(CNN) -- Australia said Wednesday that it has chosen a Dutch company to carry out the next phase of the underwater search for Malaysia Airlines Flight 370, which mysteriously disappeared five months ago this week. Australian Deputy Prime Minister Warren Truss announced at a news conference that Fugro Survey will use two vessels for the search in the southern Indian Ocean, where the Malaysian plane is believed to have gone down after it flew off course and dropped off radar. The two ships will be equipped with towed deep-water vehicles and will also use side-scan sonar, multi-beam echo sounders and video cameras in the search, Australian authorities said.
