New Search for MH370 Launches: Ocean Infinity Returns to the Indian Ocean

More than a decade after the disappearance of Malaysia Airlines Flight MH370, a new, privately funded search operation has officially commenced today, December 30, 2025. According to reporting by ABC News, the mission aims to solve one of aviation’s most enduring mysteries, focusing on a refined search zone in the southern Indian Ocean.

The operation is led by US-based marine robotics firm Ocean Infinity, operating on a “no find, no fee” basis. If the wreckage or flight data recorders are located, the Malaysian government has pledged a reward of $70 million. This renewed effort follows a previous attempt by the same company in 2018, which ended without success after covering 112,000 square kilometers.

Operational Details and Methodology

Unlike previous wide-area sweeps, this mission is described as a surgical strike on high-probability targets. Operational data indicates the search will focus on a 15,000 square kilometer zone, significantly smaller than the vast areas covered in 2014 and 2018.

The Vessel and Technology

Ocean Infinity has deployed the Armada 86 05, a specialized “lean-crewed” vessel designed to launch and monitor autonomous underwater vehicles (AUVs). This marks a shift from the vessel used in earlier phases of the 2025 campaign, the Armada 78 06. The search is expected to last approximately 55 days, conducted intermittently to account for weather and logistical factors.

The primary tools for this search are HUGIN 6000 series AUVs. These drones are capable of operating at depths of up to 6,000 meters and are equipped with Synthetic Aperture Sonar (SAS). This technology provides ultra-high-resolution imagery of the seabed, potentially allowing the team to identify small debris fields that older, lower-resolution sonar systems may have missed.

Scientific Basis for the New Zone

The decision to resume the search is driven by new flight path modeling and credible evidence that has emerged since the official Australian-led search concluded in 2017. Two primary theories have shaped the current search area.

The Marchand & Blelly Theory

The primary focus of the Armada 86 05 is a zone centered around 35.7°S latitude, 93°E longitude. This target is derived from analysis by former ESA researcher Jean-Luc Marchand and former Air France pilot Patrick Blelly. They posit that the aircraft was hijacked and underwent a controlled ditching to minimize debris, a theory that narrows the search radius significantly.

WSPRnet Analysis

Complementing this is data from aerospace engineer Richard Godfrey, who utilizes Weak Signal Propagation Reporter (WSPR) data to track radio disturbances caused by the aircraft. While Godfrey’s analysis points to a site slightly further north (29.12°S, 99.93°E), the consolidated 15,000 square kilometer search area is designed to encompass high-priority targets derived from a synthesis of these modern models.

Stakeholder Reactions

The resumption of the search has brought renewed hope to the families of the 239 people who were on board the flight when it vanished on March 8, 2014. Grace Nathan, whose mother Anne Daisy was a passenger, expressed the families’ sentiment in a statement regarding the launch.

“We have waited for so long. We just want answers.”

Ocean Infinity CEO Oliver Plunkett has previously described this mission as “arguably the most challenging” search operation globally, noting that the company’s technology has improved drastically since their 2018 attempt.

AirPro News Analysis

The return of Ocean Infinity to the southern Indian Ocean represents a significant gamble on the evolution of subsea technology. In 2014, the search for MH370 was likened to finding a needle in a haystack with the lights off. In 2025, the use of Synthetic Aperture Sonar changes the analogy: the lights are now on, and the resolution is high enough to distinguish the needle from the straw.

However, the “no find, no fee” structure places immense pressure on the private operator. By narrowing the search box to just 15,000 square kilometers, roughly 12% of the area searched in 2014–2017, the mission relies entirely on the accuracy of the new Marchand/Blelly and WSPRnet models. If the wreckage is not found in this specific high-probability zone, it may force the global aviation community to confront the possibility that the fundamental assumptions regarding the Inmarsat satellite data were flawed.
