Victor Vescovo

The Johnston was sunk during the Battle off Samar (1944) in one of the most lopsided naval battles in history.

In 2022 a submersible expedition piloted by Vescovo located the wreck of destroyer escort USS Samuel B. Roberts (DE-413) (also sunk in the Battle off Samar in 1944), in the Philippine Sea at a depth of 6895 m, making it the deepest wreck identified at this date.

In June 2023, Vescovo lost his friend Hamish Harding, whom he had been to space and sea with, when he died when trying to view the wreck of the Titanic inside OceanGate's Titan submersible. On Twitter Vescovo stated: "This has been a difficult week for the submersible community. Deep ocean diving is very safe when industry standard certifications and procedures are followed. I will miss my good friends PH Nargeolet, who I worked with closely, and Hamish Harding, my friend in sea and space."

Vescovo appeared in the 2024 ABC special Truth and Lies: Fatal Dive to the Titanic, which examined the Titan submersible implosion.

Victor Lance Vescovo (born February 10, 1966) is an American private equity investor, retired naval officer, sub-orbital spaceflight participant, and undersea explorer.

He was a co-founder and managing partner of private equity company Insight Equity Holdings from 2000-2023.

Vescovo achieved the Explorers Grand Slam by reaching the North and South Poles and climbing the Seven Summits.

Vescovo served 20 years in the U.S. Navy Reserve as an intelligence officer, retiring in 2013 as a Commander (O-5).

He visited the deepest points of all of Earth's five oceans during the Five Deeps Expedition of 2018–2019.

Vescovo grew up in Dallas, Texas, where he graduated from St. Mark's School of Texas.

He earned a bachelor's degree in Economics and Political Science from Stanford University, a master's degree in Defense and Arms Control Studies (Political Science) from the Massachusetts Institute of Technology, and an MBA from Harvard Business School where he was a Baker scholar.

In 2018, Vescovo launched the Five Deeps Expedition, whose objective was to dive to the deepest location in all five of the world's oceans by the end of September 2019.

This expedition was filmed in the documentary television series Expedition Deep Ocean.

This objective was achieved one month ahead of schedule, and the expedition's team carried out biological samplings and depth confirmations at each location.

Besides the deepest points of the five world oceans, the expedition also made dives in the Horizon Deep and the Sirena Deep, and mapped the Diamantina Fracture Zone.

In December 2018, he became the first person to reach the deepest point of the Atlantic Ocean, piloting DSV Limiting Factor, a reported US$50 million submarine system (Triton 36000/2) – including its support ship the DSSV Pressure Drop and its three ultra-deep-sea robotic landers – 8,376 m below the ocean surface to the base of the Puerto Rico Trench, an area subsequently referred to by world media as Brownson Deep.

On February 4, 2019, he became the first person to reach the bottom of the Southern Ocean, in the southern portion of the South Sandwich Trench.

For this attempt, the expedition used a Kongsberg EM124 multibeam sonar system to achieve accurate mapping of the trench.

On April 16, 2019, Vescovo dived to the bottom of the Sunda Trench south of Bali, reaching the bottom of the Indian Ocean.

Likewise, this was done aboard the Limiting Factor.

The team reported sightings of what they believed to be species new to science, including a hadal snailfish and a gelatinous organism believed to be a stalked ascidean.

The same dive was later undertaken by Patrick Lahey, President of Triton Submarines, and the expedition's chief scientist, Dr. Alan Jamieson.

This dive was organised subsequent to the scanning of the Diamantina Fracture Zone using multibeam sonar, confirming that the Sunda Trench was deeper and settling the debate about where the deepest point in the Indian Ocean is.

On April 28, 2019, Vescovo descended nearly 11 km to the deepest place in the ocean – the Challenger Deep in the Pacific Ocean's Mariana Trench.

On his first descent, he piloted the DSV Limiting Factor to a depth of 10,928 m, a world record by 16 m. Diving for a second time on May 1, he became the first person to dive the Challenger Deep twice, finding "at least three new species of marine animals" and "some sort of plastic waste".

Among the underwater creatures Vescovo encountered were a snailfish at 26250 ft and a spoon worm at nearly 23000 ft, the deepest level at which the species had ever been encountered.

On May 7, 2019, Vescovo and Jamieson made the first human-occupied deep submersible dive to the bottom of the Sirena Deep, the third deepest point in the ocean lying about 128 miles northeast from Challenger Deep.

The time they spent there was 176 minutes; among the samples they retrieved was a piece of mantle rock from the western slope of the Mariana Trench.

On June 10, 2019, Vescovo reached the bottom of the Horizon Deep in the Tonga Trench, confirming that it is the second deepest point on the planet and the deepest in the Southern Hemisphere at 10823 m. In doing so, Vescovo had descended to the first, second, and third deepest points in the ocean.

Unlike the Sunda and Mariana Trenches, no signs of human contamination were found in the deep, which was described by the expedition as "completely pristine".

Vescovo completed the Five Deeps Expedition on 24 August 2019 when he reached a depth of 5550 m at the bottom of the Molloy Deep in the Arctic Ocean.

He was the first human to reach this location.

In 2019, Vescovo escorted Titanic-historian Parks Stephenson to the wreck of the RMS Titanic for the first revisit of the wreck in 15 years.

Findings included continued extensive corrosion and bacterial growth on iron and steel surfaces.

In 2019, Victor Vescovo was recognized by Guinness World Records as the person who has covered the greatest vertical distance without leaving Earth's surface.

In February 2020, Vescovo piloted his deep diving submersible twice to the wreck of the French submarine Minerve in the Mediterranean Sea.

The retired French Rear Admiral Jean-Louis Barbier investigated the wreck of the Minerve on the first dive.

On the second dive, Vescovo was accompanied by Hervé Fauve, the son of the captain of the sunken submarine.

They placed a commemorative plaque at the wreck.

In 2021, Vescovo identified and surveyed the wreck of the USS Johnston (DD-557) at a depth of 6456 m in the Philippine Sea; at the time of identification this was the deepest shipwreck ever surveyed.
