Okay , I have a fre***** problem everytime somebody puts up Chinese Navy numbers especially in the Destroyer/Frigate category.

Just because they classify a 2000 ton piece of shit ( many of them obsolete and with no real sea legs) as a frigate or destroyer doesn't make it thus. The Type 053Hs are utter crap and yet they are included in the destroyer/frigate numbers. Even the type 053H3 is basically a corvette.

Much more beneficial would be to consider the Type 054As which are true frigates, the sovremenny's and some of the new AAW destroyers.

Please also note that most the 6k plus destroyer classes that they built recently have only 1 or 2 of the type which shows that they were experimenting and trying to perfect the ship.

this is different from us building 3 DDGs in a tranche.

Overall in surface fleet terms we are still better off then them.

And if we just get our act together even in absolute numbers we will continue to do very well indeed.

Me think that a few persons on BR are over rating the Chinese Navy. This chart shows that they still have a long time to go before they will have a sustained presence in the BoB, IOR or AS.

In case of any (percieved or real) hostilities in a far away place if the Taiwanese also start playing some nauti games, I am sure that the Chinese ships would be immediately recalled towards their "mainland".

As of now the Chinese Navy is not capable of policing the South China Sea, as well as the BoB, IOR or AS areas

Dragon Slayer

Extreme care has been taken for safety after the August 2000 disaster that killed all 118 crew of the Russian nuclear submarine Kursk. The Chakra has been retrofitted with a fin-mounted spherical escape sphere. In an emergency, the entire 100-member crew can fit into the 20-foot wide, 50-foot tall sphere and ascend to the surface.

The Chakra displaces over 12,000 tonnes underwater. That's roughly three times the displacement of a conventional 2,300-tonne Kilo class submarine currently operated by the navy. Crewmen say they are overawed by the size of their vessel. "It's incredible," says one submariner. "It's like being on board a large surface ship. One of our Kilo class submarines could fit into the Chakra's control room," he says. Crewmen can walk erect instead of crouching. The larger submarine allows for more comfortable living spaces. Conventional submarines provide bunks for only half their crew. Every crewmember of the Chakra has a bunk. Size clearly has its comforts.

I am confused. Totally Confused

How can I have a 20-foot wide, 50-foot tall sphere !!! My miniscule knowledge of maths tells me that a sphere can have only one unit i.e. radius / diameter. And every point on the surface is equidistant from its centre.

Simplest example a ball (IPL is going on !) I have not yet seen a cricket ball (a sphere) which is say 75 mm wide AND 150 mm tall.

Please clarify this escape hatch dimensions. It cannot be a sphere.

Kersi , SNaik had posted the picture of Akula escape hatch in last page here it is

From what i understand the way it works is , incase the subs gets stranded deep inside the water and it cannot come up , all crew gathers inside the escape hatch and by a mechansim they release the escape hatch from the sub and rise to the surface to be rescued by ships.

Navy sails into nuke club atop Chakra
Visakhapatnam, April 4: The Indian Navy today announced that it has gone nuclear with the INS Chakra berthed at the “Jetty X” here after a 40-day voyage from Vladivostok in Russia.

The nuclear-powered Akula II class INS Chakra has been leased from Russia for 10 months for an estimated $1 billion. Originally known as the K-152 Nerpa, it has been re-christened Chakra after the first nuclear submarine that was also leased from 1987 to 1990. The name has been invoked from the Hindu god Vishnu’s Sudarshan Chakra, a spinning disk used as a weapon in Hindu mythology.

“I have been commanding officer of two conventional (diesel-electric) submarines. I wished I could take on extra knots (nautical miles, indicating speed and endurance), play around with targets and discharge my weapons at them,” the new INS Chakra’s first commander, Captain P Ashokan, said, explaining what the submarine adds to the navy.

The INS Chakra is an SSN (sub-surface nuclear) submarine that is powered by reactors generating 190MW, not an SSBN (sub-surface ballistic nuclear) that are submarines not only nuclear-powered but also carry nuclear weapons. The Chakra will be able to stay under water longer than conventional submarines that have to surface every two days (or even every 24 hours) to re-charge batteries. The more submarines surface the more they become detectable.

The Chakra’s medical officer, surgeon commander Gokul Krishnan, said it had sailed from Vladivostok to Visakhapatnam without surfacing in 40 days. He said the endurance of the submarine is “human” not “technological”. Such long missions in the closed confines of a submarine can be taxing on sailors.

The crew of 80 under Captain Ashokan wear a “dosi meter” on the breast pocket of their blue overalls that measures exposure to radiation. A radiation safety officer takes these readings on a specially rigged machine. The “dosi meter” is like a miniature Geiger counter.

There was indeed an accident on the Nerpa two years ago when about 20 Russian sailors and dockyard workers were killed during trials. The accident was not traced to the reactors but to faulty electrical equipment. That was far less than the damage caused by the Russian sub, the Kursk, that went down in the Barents Sea after a reactor was apparently hit from the backfire of a torpedo. The submarine went down with its entire crew of 100. The reasons for the accident were never officially disclosed.

Larger than any of the submarines that the Indian Navy currently has, the Chakra has more recreation space inside its “double hull” and more places for the crew to shower in. It even has a sauna and a gym. The “rescue sphere”, a capsule that is released from the bridge of the vessel in the event of an emergency, can accommodate the entire crew.

The INS Chakra reached Indian waters on Sunday. The vessel also had eight Russian submariners on board. It was received by four ships of the Eastern Naval Command about 100 nautical miles from the coast from where it sailed on the surface.

More than anything else, the INS Chakra emphasises that Russia is the only country from which India can source strategic platforms, a fact that the Russian ambassador underlined here today.

“There is no other country than Russia that will share with India in this way. This (pointing to the submarine behind him) is a shining example of very confidential strategic information exchange between India and Russia,” Alexander Kadakin said.

But defence minister A.K. Antony used the opportunity to highlight that there were irritants in the relationship even if Russia was India’s long-time and largest defence supplier.

“I want to tell you that the INS Vikramaditya (the aircraft carrier, Admiral Gorshkov) should be here by early next week,” he told the ambassador.

“Russia should extend requisite technical support for the INS Chakra.”

He acknowledged that “the lease of the INS Chakra is a true reflection of strategic ties between Russia and India”.

I don't know about acidity.But wrt human endurance the author is probably trying to say that Nuclear submarine endurance is almost unlimited in staying underwater( measured in decades) , but due to the presence of sailors the submarine has to surface once in a while( 3 months or so for replacement).

Eric , this range is not the technical range. The technical range is exhausted only when nuclear fuel aboard is exhausted which depending on nuke submarine is usually some multiple of a decade.So theoretically you could go to moon and come back if only there was an ocean between earth and moon.Nuke subs/ships are not limited by range.

The only problem is that humans serving aboard cannot stay in confined environs(even if it is a large ssn/ssbn) for long periods of time.So they have to be replaced periodically by fresh batches.For that the Submarine has to surface accordingly.

Here 100 days has been taken as human staying capability in submarines.

And yes we can play cat and mouse games in the yellow sea easily. Or for that matter , we can play cat and mouse games in Southern pacific ocean , gulf of mexico , arctic waters etc etc . You name it.If it is a water body on the Earth(excluding inland ones) you can do it.

I believe nuke subs have a desalination plant to convert sea water into drinkable water, but food carried in the freezers might also be enough for say 100 days. thats another limiting factor.

http://englishrussia.com/2009/04/14/wor ... submarine/

in this pic of a decrepit typhoon sub you can see the crew lounge, video game and sauna. I hope our Akula has been refitted with something less ratty because these are very sub par for today's std.

another link in that page has a good feature on a TopolM crew launching a test shot from Plesetek.

Have a former colleague who served aboard two USN subs as the chef (or rather, Mess Specialist was his official designation). He said that when they would leave on patrol, they would stuff all possible nooks and crannies in the sub with food. During the first week or two of patrol, they would have fresh food to serve. After that, it was all canned/dried/frozen food all the way. Towards the end of the patrol, he was forced to improvise some interesting combinations of food. One time, the replacement sub was a little late in coming over and so they had to stay on patrol a little while longer than expected, so he ended up making sandwiches for a while until everyone on board got sick of them. However, no one starved on board, as they pack supplies for more days than they expect to patrol.

yes I have read even some spaces below the grating used in the floors of corridors are stuffed with cartons of food when moving out. people work hard in shifts and surely eat plenty. and theres no easy way to transfer food in the high seas unlike say using a pipe to feed in diesel from a tender.

a interesting entry:
http://www.navy.mil/navydata/cno/n87/faq.html

What does the crew do during its free time?
At sea, the typical submarine day is 18 hours long, not 24 hours. Submarine crews are divided into three watch sections. Each section is on duty (on watch) for 6 hours, and then spends 12 hours off watch. When on watch, the crew members are actively operating their assigned equipment. Examples of watch stations that are manned continuously at sea are: Radioman of the Watch (operates radio equipment), Quartermaster of the Watch (determines the submarine's position in the ocean), Engine Room Lower Level Watch (operates all equipment located in the lower level of the engine room), Throttleman (operates the throttles which control the main engines, which, in turn, control the speed of the ship's propeller) and Planesman (operates the submarine's diving or steering controls). Under normal conditions, there are approximately 25 crew members "on watch" at the same time. Under special conditions, such as battle stations and when entering or leaving port, everyone has a watch station.

During the 12 hours out of each 18-hour day that submarine crewmen are not actually on watch, they engage in a wide variety of activities. Crew members who are off watch eat, attend training sessions and study, both for advancement examinations, and in order to become qualified to stand other watchstations. Others may perform routine preventive maintenance on the equipment that they are responsible for (e.g., a radioman periodically changes emergency batteries on some of his radio gear, an electrician periodically inspects the ship's wiring for problems, etc.). A wide variety of activities are available during free time. The ships carry about 400 movies, which are exchanged for newer ones in each port. Card games and various board games, such as a Backgammon or Cribbage, are also popular. There are also some athletic equipment on board, such as an exercise bike, versa climber, rowing machines, and free weights. U.S. fleet ballistic missile submarines have more athletic equipment than SSNs because they have more space. SSBNs are so large that some people even run marathons by running around the perimeter of the missile compartment many thousands of times!

What do you eat?
Being a cook on a submarine is a very important and demanding job. The quality of food served has a great impact on crew morale. Imagine shopping for 120 men for six months and planning every meal! Submariners eat the same food as you would find at almost any table in an American home. They have ongoing contests to determine which ship cooks the best meals. The fresh fruit, vegetables, eggs, and milk usually don't last for more than a few weeks, but the creative cooks on submarines work wonders with canned and frozen foods to supplement the meals they create. Submariners have four meals per day - breakfast, lunch, dinner and midnight rations, commonly known as "midrats." Menus include eggs, hotcakes, and cereal for breakfast; deli sandwiches, hamburgers, and pizza for lunch; pasta, steak, chicken, and pork dishes for dinner; and leftovers for midrats.

Where do you keep all the food stored?
Submarines have several storerooms, refrigerated rooms, and freezers. On long deployments, however, the amount of food required exceeds available storage space. Cans of food are stored on the floors in the passageways throughout the ship and people simply walk on the top of the cans.


Where do Submariners sleep?
On U.S. Navy submarines, living quarters are called "berthing areas" that provide no more than 15 square feet of space per man for sleep and personal belongings. On most submarines, each crewman's bed (called a bunk, berth or rack) has a reading light, a ventilation duct, an earphone jack for the ship's audio entertainment system, and a curtain to provide a small (but welcome) measure of privacy. The crewmen store their clothing and personal belongings in a sturdy pan-like locker beneath their mattress. When a U.S. Navy submarine is at sea, lights in the berthing areas are normally dimmed. About one third of the crew is asleep at a time because submarines operate 24 hours a day. The crew works in shifts, normally six hours on, 12 hours off. Only the captain and executive officer of the submarine have private rooms, called staterooms, in which to work and sleep. Sometimes, there are more people onboard than there are regular bunks. When this happens, a few of the crewmen have to sleep in makeshift bunks in the torpedo room. These temporary bunks are fitted on storage racks where torpedoes and missiles are normally kept. Space is always very limited on submarines, and there are very few large or open spaces where people can make a bed.

What clothes do you wear?
When in port, crew members wear regular Navy uniforms. At sea, members wear one-piece blue coveralls called "poopy suits." They are very comfortable to wear and reduces the number of clothes the sailor has to bring to sea. Submarine crews usually wear sneakers or other soft bottomed shoes when at sea, as sound quieting and stealth are always foremost in a submariner's mind.

Who does the laundry?
On U.S. Navy submarines, there is an area designated for laundry, typically with one washer and one dryer. Laundry is done weekly by division on a rotational basis. Each division appoints someone weekly to perform this task.

Quite a few difference , Torpedo Tube was increased ( Relodable & Non-Relodable ) ,length of submarine was increased by few meters and most significantly noise reduction in the order of 3-3.5 times was achieved over Akula-1.

Here is a newer ONI Graph showing Relative Detectability of Akula-1 and Improved Akula.

The huge advantage of the double hull,where both hulls can if need be have acoustic cladding.The Alfa reportedly had its inner hull acousticallty treated.IT would be fascinating to compare the Chakra with the ATV,but we would never know.

but double hulls carry the penalty of increased weight for a given internal volume vs single hull. this will affect the speed and need a more powerful reactor...might have some effect on noise levels.

nerpa is akula2...the first after gepard.

if you believe the noise graph posted, Irbis (if finished to Akula1 std) and the readymade Tigr (posted as available for lease by Snaik) are still better than the latest chinese SSBN/SSN classes Jin and Shang.

the Irbis could likely be finished up with quieter akula2 std internal machinery and control systems.

the Tigr would undergo some form of refit but retain pretty much the same level of machinery probably as its a functioning sub.

in either case - we get a sub better than the best in chinese hands even better than their next follow-on class....with *40 heavy torpedo/Klub mix*

methinks its cheaper and less risk to just go with a refurbed Tigr, equipped with Klub and HWT. Russian submarine patrol tempo has been low the last 15-20 yrs so these machines would still have a lot of life

or dont choose - take both Tigr as a quick delivery option and fund the completion of Irbis as the 3rd boat....after all IN always does everything in threes, just as the Ramans of AC clarke books
:twisted:

sooner we lay in these puppies the better. spread some love and brotherhood far across the IOR.

The problem with the low patrol tempo is the question of how well the Russian subs have been mentioned. Note that till just a while back the Russian navy didnt have much money even for maintainance. The condition of the Tigr would be in question. It would need a major overhaul.

The double hull has another advantage,apart from a lot of reserve displacement and better survivability.A lot of eqpt. can be located between the two hulls instead of within the pressure hull in a single hulled boat.Some designs have had missile silos in between the outer and inner hull.Since power is from a powerful N-reactor the extra weight,etc. shouldn't be a problem.Why,even our conventional Kilos that have performed yeoman service over two decades have a double hull!

Having not been used at sea at all,the hulls sections of the unfinished Akulas should be in pretty good condition.from reports,the Russians themselves cannibalised the sections and used them as parts for their newer SSGN and SSBNs The problem will be with the eqpt. already fitted into the hulls,which could be obsolete,need replacing or tinkering with.We know the story of wiring in the Gorshkov! The Akula design has come a long way with the Gepard,quite an advancement from the first lot.So one would expect the later std. of eqpt. to be fitted and hopefully the future Akulas will come with a full inventory of sensors and weaponry.

The extra space aboard an N-boat used for crew comfort is really needed especially as deployments can last upto 90 days/3 months.With increased automation and AIP,some newer designs are trying to provide crew members with their own mini-cabins/compartments instead of just "3-tier" cattle class bunk beds! It is amazing how one can get accustomed to living in small confined spaces within a very short time.

Tx a million for these clear pics Arijit.It answers one big Q,why there are no doors for the decoys above the torpedo tubes as in regular Akulas.If one looks at the first pic in particular,it is very clear that the tubes for the decoys do exist! They have just been plated over with the acoustic cladding and their distinctive outline and shape can clearly be seen underneath.Along with the plate on the fin that can later on house the SOKS sensors,it means that the boat has been built to Ak-2 std. and these two key features can easily be added at any future date.The location of the large forward flank passive sonar array can also be seen between the two white lines on the port beam.

Most likely the SOKS and Big Countermeasure suite are just too sensitive to be shared across , else see no reason why it cant be on Chakra.

no hydroplanes on the bow, none of the sail. how exactly does the front end control itself?

The Akula do have hydroplanes in the bow , they can be unfolded in the bow when not in used.

Austin I don't think they fold as such , they are retractable just like the ones on Astute and Seawolf.
