Recently allowed for publication pics of first of Project 955 sub, Yuri Dolgorukiy, christening event published at web-log of Sergey Kuznetzov, presenter of Smotr military TV-show at Russian NTV channel.

http://pilot.strizhi.info/2007/04/17/3111#more-3111 - what everyone saw (sub's curtained tail)
http://pilot.strizhi.info/2007/05/04/3373#more-3373 - what not everyone was allowed to see (other parts of sub)
http://pilot.strizhi.info/2006/10/25/1105#more-1105 - 955 factory model at Sevmash

I advise you to visit his weblog quite often for really cool stuff.

She looks a very clean design.
The Russians have come a long way!

Why are Russian subs always so interesting looking and US subs are tubes with fins? :'(

The reason for the difference in looks is that the US subs are a single hull construction. With this methodology, the outside of the hull is the pressure hull (except for the tapered portions of the bow and stern). Russian subs tend to be a double hull, basically a pressure hull with a fairing on it. This allows them to have slightly more streamlined shapes at higher manufacturing and materials costs. The slight gain in hydrodynamics has not been worth the extra cost for the US subs. In fact if you look at the current Russian boats, they too are moving towards the US design.

I know the technical reasons. It was a rhetorical question. Sorry. ;)

Now that was something I _didn't_ know, so that was useful to me, :)

cheers,

This is a link to a Russian news story about the recent test of the new missile to be deployed on the 955 "class" and its failure. Of the last 11 test 6 of them have ended in failure. It will be interesting to see how this effects the 955's as the class was delayed because the the first missile slated to be used with the boat also had a handful of failures and it was decided to go with the current missile.

This failure of first stage seems to be Quality control issue , seems more to me like a deliberate attempt to sabotage or delay the program perhaps by rival design bureau.

They have first stage failure before and its impossible that post failure analysis this is a fundamental design flaw issue.

Found these computer-generated models of the Project 955 Borey while surfing.

Those models show the Borey with a full complement of 4*65cm, 4*53 cm and 6 outside tubes remensicent of your modern Russian attack sub.... Wouldn't that be a little overkill for a boomer?

Maybe they were planning a companion SSGN class at one time?

The external tubes are probably only be used for large submarine simulator type decoys. IIRC some earlier commie submarines had dedicated tubes for this too, in contrast to the USN which fires its submarine simulator out of the normal tubes (displacing weapons internally as a resulting) while having only small dedicated tubes for smaller types of decoys and noisemakers.

The mix of 65cm and 53cm tubes is logical enough for the Russians. They have some very long range anti submarine missiles you can only shoot out of 65cm, but most of the main anti submarine torpedo types they have are 53cm. So you need both. This is just what you get when you let the Russians design weapons, they love specialization. They'd design a different torpedo and torpedo tube caliber for each class of western SSN if given the chance.

Yup they still got much life in them yet and are great boats with fascinating history.
