Nobody in his right senses is going to RAM the ice layer. Instead you carefully blow the ballast and PUSH. Russian subs are double-hull, thus having bigger buoyancy, this helps a lot in such kind of operations. Double hull also means added safety for pressure hull against mechanical damage.

Ah thanks once again , I thought Gepard was the first Russian submarine to have an integrated Combat Management System.

Any idea what makes Gepard unique among Akula SSN ?

First BIUS Tucha (Soviet term for Integrated Combat Management System) was created was created in 1967 and installed on Pr.667 boomers. In later years several more advanced systems like Brest, Akkord, Almaz, Uzel (for diesel subs) appeared. In 1981 Omnibus system was created as a universal BIUS to be installed on all nuclear subs.
Gepard is not unique, it has modernized versions of equipment of earlier Akulas (or rather Schuka-B). The most visible element is much smaller tailplane container for VLS. Also it has modified version of SOKS, BIUS and other electronic equipment. In other terms it isn’t different from Vepr.

The Design Bureau may have been in Russia. Yet, that was many decades ago and only one true carrier was designed at that. Which, is again a hybrid design with a ski-jump. Further, Russia has invested little in the development of Carrier Design or Aviation in all of those years since. As a matter of fact the Kuznetsov has deployed just a few times in the last couple of decades. Then of course we can talk about the Su-33’s. Which, have yet to receive any worth while upgrades at all in all of those many years.

The truth is France has only one Carrier. Yet, it is light years ahead of Russia in Carrier Design, Development, and Naval Aviation.

Yes. It may have been in Soviet Union. As well as the shipyard. During the last 50 years that designer has come up with at least three designs of full scale carriers including both ski-jump and catapult.

Russia did not build and develope much of her Carrier Force. As they came from Ukraine and even then only one was totally completed (Kuznetsov) and the other (Varyag) laided derelict for years before being sold to China. So, Russia is hardly a expert by any means……..
Let’s also not forget the ex-Gorshkov is a conversion of a hybrid Cruiser/Helocopter Carrier. Which, of course gets back to my point…….:(

Would you care to name the Ukrainian design bureau which designed Project 1143?
This is really amazing…

Wanshan the 22350 frigate looks so much like Talwar class , infact if you just put aside the single arm Shtil-1 launcher on the talwar , nothing looks dissimilar.

I though 22350 will be a larger displacement size frigate/destroyer and would be far more stealthier , what is the source of this image ?

snake65 point taken 😉

22350 will be around 4000-4500 tons, there’s no doubt of that. And general design will have 11356 as basis.
The first hull may be quite different ship from the next ones (that’s normal Russian practice – the desired equipment and weapons are never ready when the first hull is already in the water).
This all depends how soon they will get ready the coveted Polinom/Redut-K air defence system. A reduced version will go on second hull of 20380, the full version is slated for 22350.

Task Fincantieri to finish Vikram and after that order second IAC from them:diablo: Vikram will be in water in a couple of days anyway

Can someone help me on this:

-when the accident occurred, was the Sub submerged or on the surface?

-Is it correct that the freon sistem is MANUALLY Actuated on all subs of the RuN, being the automatic sistem a requirement from the Indian Navy????

thanks in advance

– persicope depth, returning to base

– manual only.
