re: Argentine submarine missing at sea

This sank a year ago. They found it today in 2600 feet of water...

(no message)

An interview with a family member said that family members were to be shown photos of the ships and that their family members were in side it.

The Seabed Constructor, a vessel owned by US search firm Ocean Infinity, which set out in September on the latest attempt to find the San Juan, made the discovery.

The Seabed Constructor is equipped with cameras that can be submerged to a depth of 6,000 meters. It was to receive a reward of $7.5 million if it found the missing sub.

At 2600 feet, arent we talking about compacted debris at this point? What does pressure do to the sub at that depth?

Depends on when the hull was compromised. Deep enough and everything inside just kinda instantly blows apart and burns, basically. The mechanical impact of the pressure change just pulps and crushes everything. But, do you remember how your bike pump would get hot when you'd use it to fill your bike's tire by raising the pressure quickly? Or, even better, how a diesel engine operates by compressing the fuel/air mix until it gets hot enough to burn? Same idea with the air inside the sub, so all that smashed stuff just basically goes WOOF before it mixes with the sea.

If the hull were shallower when it let go, maybe those sailors were blown apart and killed instantly by the impact of the pressure change and the water hitting them and didn't have to drown, but the temperature wouldn't rise fast or high enough for WOOF. Just "squish".

If it were shallower still... well, that's a less messy, but far more terrible death. The LUCKY ones would drown immediately when the hull opened. The trapped ones...

Its roughly 40 psi for every 100 ft of depth... so at 2600 ft that would be a little over 1000 psi.

TR1700 class subs have a test depth of 900-1000 ft according to Google search. So they normally operate at 400 psi max. I'm sure there is some significant hull damage/compression at 2600 ft.

Interesting that this thread was bumped exactly one year from the OP. Did you have this thread bookmarked or did you search and find this thread?

---

Searched. I remember it from last year and knew it officially went missing a year and 2 days ago.

They had a ceremony for the families 2 days ago and the President vowed to never stop looking until they found it. Pretty crazy

Argentina has a submarine?

When I saw this thread had been bumped, it gave me a sinking feeling.

Someone mentioned the Sub (U-505) at the Science Museum in Chicago...the one you technically cant take pictures of. I seen it!
