Elon Musk’s “Wild Boar” Sub: A Quick Dive into the Thai Cave Rescue
In the middle of a hot July morning in 2018, the world’s most famous rocket guy, Elon Musk, decided to put a dent in the latest Cave Rescue saga that had everyone on the edge of their seats. He tweeted, went to the flooded tangle, and brought along a prototype mini-submarine that he’d named “Wild Boar.” He even filmed it for Insta – but don’t worry, no more slide‑sharing allowed in this article.
What Exactly is the “Wild Boar”?
- Kid‑Size Submarine – fits within a narrow corridor, lighter than a decent pair of diving goggles.
- Built from Falcon rocket parts – because why not reuse rocket tech in a cave?
- Ready for rescue – can be carried by two divers and doesn’t require a user to know how to use oxygen bottles.
- “Plain English” in that it’s basically a little navy boat with a liquid oxygen transfer tube as its hull.
Why Did Musk Jump into the Cave Business?
He had originally floated the idea of a giant air tube or drilling into the rock with SpaceX radar, but the more practical solution he offered was a boat smaller than a swing or an open‑handed hovercraft.
Let’s talk logistics for a moment
He did a quick test run in a LA swimming pool – divers escorted the pod, who looked like a half‑full submarine – and everything looked good. Two divers could haul it, it wasn’t fragile, and the little pod could travel through almost any wounded space in that nasty cave system.
What happened on the ground?
By Monday night, a firing squad of elite divers had slipped out eight of the 12 boys and their 25‑year‑old coach from the inner part of the cave. The rescue was aided by world‑class teams and, sadly, was not without tragedy: a former Thai Navy SEAL diver died of a lack of oxygen on Friday.
The Thai forces had a base in Cave Three, two kilometres from the entrance. The squad of boys, however, were still deeper underground – also about 2 km from the entrance, a spot that was barely accessible.
Bottom line: Is the Wild Boar actually going to be used?
As of that month’s timeline, the Thai rescue crew had no concrete plan to enlist Musk’s prototype. But the mere presence of a mini-submarine that could fit into tight spaces was a reminder that rescue operations can go anywhere – from the depths of the Pacific to the-dark corners of a cave system.
Before we can say “thank you, Elon,” let’s hope the boys and the coach will soon be back in the sunlight, and that the wild boar‑tech stays for good engineering stories instead of a side‑kick gadget in the tech world.
