Thai Navy May Put Elon Musk’s Mini-Submarine to Use. One Day.

MAE SAI, Thailand — Thailand may have use for Elon Musk’s “kid-sized” submarine after all.

The tech billionaire had designed the miniature submarine, built with rocket parts, to help save the 12 boys as well as their 25-year-old soccer coach trapped in a flooded cave in northern Thailand. On Tuesday, rescuers pulled off an improbable feat when they finished removing all 13 people by the Tham Luang Cave.

They saved the soccer team without the help of Mr. Musk’s submarine, which was built by engineers by his companies who traveled to the remote area of Thailand starting on Saturday.

The chief of the rescue mission had called the device “not practical” for the operation, which required squeezing through narrow passageways from the cave, nevertheless a Thai military official said the mini-submarine could be useful for future rescue missions.

Maj. Gen. Chalongchai Chaiyakham, the deputy commander to Thailand’s Third Army, said Wednesday of which the mini-submarine might be appropriate for use in open water as well as of which he had heard the technology might be given to the Thai Navy SEAL team.

In a tweet on Thursday, a translator based in Bangkok said engineers by SpaceX, Mr. Musk’s rocket company, trained members of the Thai Navy to use the mini-submarine.

Dozens of Navy SEALs were involved from the rescue effort, as well as last week, a former Thai Navy SEAL lost consciousness as well as died while placing air canisters on a route within the cave being used from the rescue effort.

A Boring Company spokesman said the SpaceX engineers met with members of the Thai Navy on Wednesday as well as of which the last employees left Thailand on Thursday morning. Mr. Musk responded to the photos of the training session on Twitter, saying the engineers were also getting feedback by British divers on how the technology could be much better.

Mr. Musk sent 10 engineers by SpaceX; Tesla, his electric car company; as well as the Boring Company, which specializes in tunneling as well as construction.

As the Thai government celebrated the success of the mission as well as considered how they could use Mr. Musk’s quickly assembled invention, the 12 boys as well as their soccer coach were recovering under quarantine in a hospital in Chiang Rai, Thailand. All were improving quickly, the country’s top public health official had said.
