Back in the water...

It appears that the real Alvin is now prepping for sea trials after the largest refit in its history:

and

I think these are the first real photos of its final appearance after the refit...

according to navsource.org, its official cruising speed is 2 knots, but i don't know how accurate that is.

Thats really cool, one of the original deep sea vessels is still being modernized after nearly 50 years of service

I agree and that is the way it should be. I would like to see an Alvin II someday like the mir one and the mir two.

If the Alvin only goes 2 knots,, they need to bring the Alvin real close to where they want to observe ? how long can the Alvin be on a dive before the Alvin runs out of power?

I hope you're not going to refit your bueatiful model Tim. I saw it last year at Carmel and it is awesome.

no, not a refit of the existing sub...

but i have always thought it would be cool to have one of each of the 4 major refits.

41 million for the refit? Sounds like the $150.00 hammer and the $200 toilet seat rises again.

I don't know,, if you think about it,, look at what people want for RC subs, The only production RC sub is the Neptune and they aren't cheap. but when you have three people's lives at stake being 16,000 feet deep, (have no clue as to what pressure that would be) I would think that 41 mill is believable. Plus there is only one Alvin in the whole world and every piece and part must be custom made for that only Alvin and it is almost comparable to space travel. It is as dangerous Heaven forbid that hull gave way to that pressure, it would be like the space station loosing it's seal. how much would a space craft the size of the Alvin cost? built by NASA? but yeah you're right ,, a lot of money for sure.

current price of titanium per lbs is around $50, the hull started as more than 40,000 lbs, so just the cost of raw material is over $2M alone. add in all that machining time on two 20,000 pound parts, and its going to be a @#% load

The union labor and inflated costs for government spec parts are what the money was spent on. Look at how much is spent on a nuclear sub refit. The game is played by submitting a lowball bid, then go over budget by 1000 %. It's obscene. Alvin, with her 41 million refit, can't go below her depth before the refit because of batteries. So why even do the refit?

Well I don't know,, the one thing I like though, is that the hull has been replaced and she made over 4000 dives, how much can that hull take?? It don't matter to me what it costs. I love that sub and it will live on. thank God. I think the Alvin looks even cooler. If I had enough money ( I don't have it ) I would love to go on a shallow dive on her. but anyway the Alvin looks even better.
