# MH370 search resumes in the southern Indian Ocean with new deep-sea technology
A fresh search for Malaysia Airlines flight MH370 has begun in the remote southern Indian Ocean, reopening one of aviation’s longest and most painful mysteries nearly 12 years after the aircraft disappeared.
The renewed effort is being led by Texas-based Ocean Infinity under a "no find, no fee" arrangement with the Malaysian government, according to the transport ministry. The company will be paid only if it locates the wreckage. The new search phase is expected to last up to 55 days and focuses on a smaller target area of about 5,800 square miles, shaped by updated satellite data, drift modelling and expert analysis.
MH370 vanished on March 8, 2014, shortly after taking off from Kuala Lumpur for Beijing with 239 people on board. Less than an hour after departure, its transponder went dark and the aircraft vanished from civilian radar. Military radar later showed the plane veering west over Malaysia before heading south over the Indian Ocean, sending investigators into a vast and expensive search effort that eventually covered more than 46,000 square miles off Western Australia.
That first multinational hunt ended in 2017 without a breakthrough. The absence of a confirmed wreck site has fuelled years of theories, frustration and repeated appeals from families for the search to continue. Since 2015, fewer than 30 pieces believed to belong to the aircraft have washed ashore in locations scattered thousands of kilometres apart, from Réunion to Mozambique.
Ocean Infinity is deploying autonomous underwater vehicles capable of diving to nearly 19,700 feet and remaining underwater for days. The robots use side-scan sonar, ultrasound imaging and magnetometers to build three-dimensional maps of the seabed, detect debris and identify metal signatures. If the scan finds something promising, remotely operated vehicles can descend for closer inspection.
The Malaysian government’s decision marks another attempt to turn improved technology and tighter targeting into an answer that previous searches could not deliver. Malaysia’s official probe in 2018 said the aircraft was likely deliberately diverted from its route, but it stopped short of assigning responsibility.
For families of the passengers and crew, the restart matters because the search is still tied to a larger need for closure. The report says relatives from China, Australia, Europe and elsewhere have argued that finding the aircraft is important not only for the dead but also for aviation safety. China and Australia have both welcomed Malaysia’s move, underscoring how the case remains globally watched even after years of silence.
