US ocean robotics to lead MH370 search 11 years after Malaysia Airlines flight disappeared

Eleven years after Malaysia Airlines Flight 370 (MH370) vanished without a trace, the search for the aircraft is officially resuming. On 3 December 2025, the government of Malaysia announced that private marine-robotics firm Ocean Infinity will lead a new deep-sea operation starting 30 December, under a “no-find, no-fee” contract, reinitiating an attempt to locate wreckage from the missing Boeing 777. 

The upcoming mission will deploy unmanned robotic submersibles equipped with high-resolution imaging systems to scour a targeted 15,000-square-kilometre zone of the southern Indian Ocean, chosen by experts based on updated data analysis as having the highest probability of yielding the jet’s remains. The search will run intermittently over 55 days. 

MH370, a Boeing 777 carrying 239 people on board, disappeared on 8 March 2014 during its flight from Kuala Lumpur to Beijing. Contact was lost less than an hour after take-off; military radar later traced a turn — instead of heading northeast, the plane flew west across peninsular Malaysia before heading south over the Indian Ocean, where, investigators believe, it eventually ran out of fuel and crashed far west of Australia, thousands of miles from its intended destination. The Boeing 777’s last recorded transmission came at 1:19 am: “Goodnight Malaysian three-seven-zero.”

The aircraft was carrying 12 Malaysian crew members and 227 passengers, the majority of whom were Chinese nationals. Also on board were 38 Malaysian passengers and seven Australian citizens and residents, along with travellers from Indonesia, India, Iran, Ukraine, Taiwan, New Zealand, the Netherlands, Canada, France, Russia and the US. 

Over the years, MH370’s fate has remained one of aviation’s most haunting mysteries. Investigators have yet to determine the cause, with theories ranging from deliberate pilot action to a possible hidden intruder in the avionics bay. The official report notes that “flight simulator trials established that the turn back was made while the aircraft was under manual control and not using autopilot,” leading some experts to conclude the diversion was deliberate and carefully planned.

Despite extensive multinational searches that scanned over 120,000 km² of ocean and seabed, only a few small debris fragments have washed ashore — most famously a confirmed wing part on Réunion Island in 2015 — but no large wreckage or bodies have ever been found. A prior private expedition by Ocean Infinity in 2018 also ended without success.

What happened on July 29!

In 2015, the first suspected debris from Malaysia Airlines Flight 370 was found on Réunion Island in the Indian Ocean. The flaperon, part of a plane’s wing, was later confirmed to belong to the missing Boeing 777. MH370 vanished in 2014 with 239 people… pic.twitter.com/vckjRBCKQa

Under the new contract, Ocean Infinity will receive payment only if substantial wreckage is discovered. The company says that advances in underwater robotics and refined analysis of ocean data now offer a better chance at success. The contract stipulates that Ocean Infinity will receive payment — reportedly US $70 million — only if substantial wreckage is found. 

“The latest development underscores the government of Malaysia’s commitment in providing closure to the families affected by this tragedy,” Malaysia’s transport ministry said. 

For many families of the 239 people lost on MH370, the renewed effort reignites a faint hope: after more than a decade of uncertainty, there may finally be answers, or at least a chance of closure. Danica Weeks, whose husband, Paul Weeks, was among the passengers on MH370, expressed relief at the announcement. She said she was “incredibly grateful and relieved that the Malaysian government has committed to continuing the search.” She added, “We’ve never stopped wishing for answers, and knowing the search will go on brings a sense of comfort. I truly hope this next phase gives us the clarity and peace we’ve been so desperately longing for, for us and our loved ones, since March 8^th, 2014.”

While the southern Indian Ocean presents enormous challenges for search teams, the renewed effort offers families and investigators a long-awaited chance for answers.
