DHAKA: Malaysia will send more equipment to the southern Indian Ocean to join the search for Flight MH370 which went missing four months ago.

A minister said on Sunday, reports The Straits Times.

Defence Minister Hishammuddin Hussein said a Malaysian navy ship equipped with a multi-beam echo sounder, a device to map the ocean floor, would set sail on August 4 for the deep-sea search zone far off western Australia.

State energy firm Petronas, together with Deftech and Phoenix International, would deploy a towed device called a synthetic aperture sonar to scan the ocean floor, he said.

Shipbuilder Boustead Heavy Industries, together with iXBlue Australia, would send a deep towed side scan sonar with a remotely operated vehicle.
