Another Russian submarine fire.

That said, it is a high performance pressure hull.

But think of the crew stuck inside. Wonder how quickly the "Hot in here?" joke got old.

Not all hulls are titanium. It's really expensive to manufacture and use. IIRC only the Alfa was an all-titanium hull (mostly because they thought it'd help with MAD), and I think Typhoons use it as well (mostly because they thought it'd stand up to the ice) though it's used in varying degrees in other subs.

Only the Alpha and Mike class boats had a full titanium hull.

Btw could somebody explain why in case of Projekt 705 class usually term 'Alfa class' is used in? I see that NATO phonetic alphabets include both 'Alpha' and 'Alfa' for letter 'A'. Is there some specific reason for use of 'Alfa' instead of 'Alpha' in case (like other sub having 'Alpha')?

According to this listing only 'Alfa' is correct.

I consider myself nowhere near an expert on Russian subs but my understanding was that it was the Alpha only

I was also in that understanding.




P.S. Couldn't resist urge to correct your post.
P.S.S. ...to form pointed to be correct by Steve. Thanks Steve!

The Papa also had a Titanium hull as did the project 865 Piranha boats. The Project 1910 Uniform class might have it as well.

Edit: Project 865 not 855. Typo on my part.

Okay.. Okay.. I forgot about the Papa Class..

Age does catch up with me eventually....

Alfas were cool... Had a neat reactor design using liquid lead. Loud as hell though, but fast as hell too...

I stand corrected. Thanks TLAM!

Look at this photo taken before the fire ... : http://www.barentsobserver.com/subma...663-58932.html





Doesn't that look like a crude cut in the hull on the bottom left of the port bow?

Perhaps an explosion earlier somewhere else was being reparied ...

Why such a huge cut on a very important area such as a torpedo room?

Are the russians into module replacements?

I don't think so

[phil21]

i think this looks more like the bow sonar array. The torpedotubes are located above this section. The crude cut is interesting, as is the 'damage' to the sound insulation panels. Maybe they were installing new insulation and as they had to replace the lighthull anyway, they were not really careful when cutting it open.

Just my thoughts...

Looks like a patchwork quilt to me
