Scintillating Submersibles.

Wow some great pics there, thanks for sharing, I find this stuff very interesting and the engineering always impresses me.


I think the Pakistani Navy had some of these, when my late dad took me on one, in the late 60s !!!!!



Impressive.....thanks for posting up, gts.:cool:


Yes, yes. All of this is most impressive.

But where the hell are the pictures of the NEW CAR, dammit ?!?!?!?!?!?

I traded my 2010 Subaru STI in for a new car for the wife and kids,
2015 Volvo XC60 R Design with Polestar tune.....325 HP and 354 lbs Torque, nice and safe kid and grocery hauler.

The Type VII was an outstading design.
At a time when American boats were made with riveted construction, the Type VII used all welded hulls with modular construction.
The high quality steel used in the pressure hull allowed diving depths that exceeded anything the Allies had, even at the end of the war.

At the early part of the war, US boats had max depth of 300 feet, at the end of the war, had increased that depth to 450 feet through by adopting welded construction and higher tensile steel.

The Type VII routinely dived to 600 feet, and as described in the book (and movie) DAS BOOT, was able to dive to 300 meters/1000 feet in emergencies.

Post-war Type VIIs were studied intensively by US and Soviet navies.
For the US, that led to the Tench class diesel boats, and to the Russian Foxtrot class diesel boats.

In the submarine community, DAS BOOT is regarded as THE most realistic submarine movie yet.
I read the book while at sea years before the movie was made. The book has photos of that war patrol.
There's also a companion book called U-Boot Wars that documents the next ar patrol by the author, Lothar Gunther Buchheim.

While the Type VII was a great design, the boat could have turned the tide for Germany was the Type XXI, which the most advanced submarine in the world at that time.

The Type XXI was a superlative design which was built for underwater speed and endurance.
Faster than any destroyer, and able to stay submerged for days, it could have inflicted huge damage on Allied fleets.

Fortunately, like many of Germany's wonder projects, it came too late.
Here's a link to the only surviving Type XXI, which is in Stockholm.
http://www.ipmsstockholm.org/magazine/2003/11/detail_uboot_xxi.htm

The Type XXI was the pattern for all post-war submarines up to 1953.
Up to that point, all submarines (non-nuclear and nuclear) used a variation of the Type XXI hull form.
Even the USS Nautilus, and the Skate class looked similar externally to the Type XXI.

It was only after 1952, with the development of the USS Albacore, did the US and eventually the world, shift to the now common modified teardrop hull.

As far as submarine design, I rate the Type XXI as:
1) A decisive paradigm design shift towards major underwater performance as opposed to mixed surface/submerged operation as with the US during WWII.
The next major design leaps are:
2) Nuclear propulsion (USS Nautilus),
3) The teardrop hull (USS Albacore research submarine, and USS Barbel class, which was the first warship using the teardrop hull, though diesel-electric),
4) The marriage of the pure teardrop hull with nuclear propulsion (USS Skipjack), which had speed and maneuverability that was breathtaking, and held the Atlantic crossing speed record by any vessel for over 20 years.
5) Modified teardrop hull, nuclear propulsion, much greater diving depths, and spherical bow sonar array with mid-mounted torpedo tubes (USS Tullibee and Thresher). A more practical design than the pure teardrop hull like the Skipjack and easier to construct. All US submarines are based on this basic design.

cool, nice write up Sub. The German U-Boats always fascinated me. Das Boot has always been a favorite, never read the book but i will purchase it tonight.

Right across the street was the German Naval memorial built in 1926. Amazing place with a beautiful underground ceremonial hall. There were wreaths down there from the Tirpitz, Bismarck, and Prinz Eugen. The really neat part is that it is an international memorial, with several wreaths and plaques dedicated the US Navy sailors and ships. Beautiful place if any of you are ever in the Kiel area.

Thanks for posting the picture of the VERY nice SUV, Paul. And a beautiful color, I might add. To my eyes it looks like "gun" metal gray.

I'm at work (as is usual whenever I post), & you have just made a little contribution to helping me sleep in my Call Room tonight.

Now, what about pictures of the front, back & the interior.
By the way. The Subaru WRX STi remains one of my all time favorite cars. I still have a goofy smile plastered on my face, just remembering the time I last drove one !
You are obviously a better & less selfish Man than I am.

Take Care, Paul.



P.S. Picture of an area of the Atrium at the airport in Riyadh. (King Khaled International).

Mercedes Makeover.

Hey, Paul.
I've been waiting for more shots of your Volvo for the last hour or so.
I assume that you've gone home from work, just so that you can take more pictures of the SUV & then post them from work.

Meanwhile, guess what I've dug up from visiting my Mom in Lahore, just a few days ago ?

I'd like to give SubSailor first shot at letting all of us know which vehicle this is. My colleague in Lahore, who is an IVF specialist, restored it after buying it from the Pakistan Army at an auction & got recognition from this particular vehicles' club in Germany.
I've been told that Mercedes made just 2500 of these, out of which the Pakistan Army bought 1500. About 1000 working examples survive in the world & I was fortunate enough to have a ride in one, thanks to my dear friend & colleague, Dr. Salman, who proceeded to take me for an ice cream cone from McDonalds', at my request. I'm such a kid !

Fire away, Sub !!!






P.S. Shan Jee !! Check out my best "Chaudhary" (Landlord), pose. What else did you expect ?!?
I'm in the Punjab, Man !!!!

Not at all, honestly i didn't give much up. The Volvo is a blast to drive and it's quick. With the Polestar tune and paddle shifters its pretty damn cool. Handles the autobahn much better then the Subaru. Right now i'm driving a beater BMW wagon, but am looking for an older Volvo Amazon as a daily driver/project as well.

Plus i have all the bikes....i have more then i need. Some of the bikes will go when i get back. It's just too much to have, especially with 3 kids.

Yes. Alright. Very good.

But where the HECK are the pictures of the vehicle from the front, back & the interior, Paul ?

Hello ?!?
