- This rare film shows the design and construction of the Alvin submersible DSV-2, made in conjunction with the Woods Hole Oceanographic Institute. A groundbreaking craft, Alvin was designed as a replacement for bathyscaphes and other less maneuverable oceanographic vehicles. Its more nimble design was made possible in part by the development of syntactic foam, which is buoyant and yet strong enough to serve as a structural material at great depths.
The vessel weighs 17 tons. It allows for two scientists and one pilot to dive for up to nine hours at 4,500 metres (14,800 ft). The submersible features two robotic arms and can be fitted with mission-specific sampling and experimental gear. The plug hatch of the vessel is 0.48 metres (1 ft 7 in) in diameter and somewhat thicker than the 2-inch (51 mm) thick titanium sphere pressure hull; it is held in place by the pressure of the water above it.
In an emergency, if Alvin were stuck underwater with occupants inside, the outer body, or cladding, of the submersible could be released and discarded using controls inside the hull. The titanium sphere would then rise to the surface uncontrolled.
Alvin, first of its ship class of deep submergence vehicle (DSV), was built to dive to 2,440 metres (8,010 ft). Each of the Alvin-class DSVs have different depth capabilities. However Alvin is the only one seconded to the National Oceanic and Atmospheric Administration (NOAA), with the others staying with the United States Navy.
Alvin's first deep sea tests took place off Andros Island, the Bahamas, where it made a successful 12-hour, unmanned tethered 7,500-foot (2,300 m) test dive. On 20 July 1965 Alvin made its first 6,000-foot (1,800 m) manned dive for the Navy to obtain certification. On 17 March 1966, Alvin was used to locate a submerged 1.45-megaton hydrogen bomb lost in a United States Air Force midair accident over Palomares, Spain. The bomb, found resting nearly 910 metres (2,990 ft) deep, was raised intact on 7 April.
Alvin (DSV-2) is a manned deep-ocean research submersible owned by the United States Navy and operated by the Woods Hole Oceanographic Institution (WHOI) in Woods Hole, Massachusetts. The vehicle was built by General Mills' Electronics Group in Minneapolis, Minnesota. Named to honor the prime mover and creative inspiration for the vehicle, Allyn Vine, Alvin was commissioned on 5 June 1964. The submersible is launched from the deep submergence support vessel RV Atlantis (AGOR-25), which is also owned by the U.S. Navy and operated by WHOI. The submersible has made more than 4,400 dives, carrying two scientists and a pilot, to observe the lifeforms that must cope with super-pressures and move about in total darkness, as well as exploring the wreck of Titanic. Research conducted by Alvin has been featured in nearly 2,000 scientific papers.

Alvin is almost 60 years old and is still going strong!
Yes although according to Wikipedia: The current Alvin is the same as the original vessel in name and general design only. All components of the vessel, including the frame and personnel sphere, have been replaced at least once.
And it can dive more than twice as deep now plus it is more roomy with replaced pressure sphere.
@@PeriscopeFilm It's like the enterprise refit from star trek lol
This was the Apollo command module of the sea. Ocean exploration had a lot of parallels to the space program in the 60s. The Trieste reaching the Challenger Deep was basically the moon landing and Alvin was a spaceship that could go anywhere humans wanted to take it.
The virgin Titan vs the Chad Alvin
Omg I have came across the blueprint for the Alvin. Crazy cool
Alvin is the reigning champion of submersibles 🏆
The only submersible I'd feel safe going down in
Now THAT is how to build a deep-diving submersible....
And Alvin is still doing its job at Woodshole Inst. almost sixty years and counting.
Proud of our Woods Hoke scientists, engineers, technicians and support personnel!
Woods Hoke lol
Woods Hole
Also used to recover the lost US hydrogen bomb off Palomares, Spain.. Gotta love US Naval research!.

This film goes back to the beginning of Alvin's operation, right?
Here's the thing most people don't understand. THERE ISN'T A SINGLE PIECE LEFT FROM THE ORIGINAL ALVIN THAT'S BEING USED ON THE CURRENTLY OPERATIONAL DSV-2 NAMED ALVIN!!!!
The Alvin has been rebuilt and modified enough times over the years that every piece of the original submersible has been replaced by newer parts. It's been completely rebuilt at least 2, 3 times. Every part HAS been cycled through with new components at least 2-3 times -- sometimes more.
I'm not kidding... what's in operation is Alvin in-name only using the same name and hull number. It's really an entirely new submersible.
The original sub couldn't even dive to 10,000ft. It had a depth limit around 8,000ft. If you look up its retired sister ship, DSV-3 Turtle, it's closer to the original configuration of the Alvin as it was built.
When Alvin explored Titanic, it did so with the SECOND pressure sphere installed in the vessel which increased its depth capability to approximately 15,000ft which was well within Titanic's zone (12,500ft approx). The latest pressure sphere on the revitalized Alvin takes its depth to just over 4 miles deep, over 21,000ft depth.
Interesting comments. The Alvin I suppose is similar to an aircraft, constantly upgraded and kept in new condition because -- failure is not an option.
And yet Alvin is still recognizably Alvin. My dad was involved in its early days (1963-1965, I think), and it was like a member of the family. I only saw Alvin in person once, disassembled unfortunately, though that was cool in its own way. Great to see this video of the incarnation I remember.
@@museislander what was your dad's name?
The Submersible of Theseus.
The second Sphere was Titanium the first was steel, the frame was aluminum a new titanium frame was installed in the 70's. A lot of upgrades over the years
I love every minute of it. Five years on Alvin and Lulu.
Gotta love US Naval research!
This little guy discovered the first hydrothermal vents in the 70s
+PeriscopeFilm, do you have a video on Pisces the submersible? I am doing a paragraph on the comparisons between Alvin and Pisces and would enjoy a video on Pisces
Pisces appears in this film

Any film of Aluminaut? The aluminium submersible that once recovered Alvin when it sank.

What do they use for the wires that pass thru the pressure vessel!! Thats gotta be one amazing cord grip to withstand that pressure. Even the cable that must be used to! Extremely curious
The pressure isn't that high. Look at Diesel injection systems. The pressure developed there is more than ten times higher. And the cabling and the pass-throughs have no problem with that.
Alvin whats up man.
I'm guessing that the CEO of ocean gate watched this and completely ignored it.
