Some Info on the MiG-29Ks...

MiG-29Ks RD-33MK engines have a Take-off re-heat thrust of 10,500kgf each! http://www.youtube.com/watch?v=qCIJtfSPQg0 (time 3:55 - 4:05) . Normal re-heat thrust is 9000kgf which is what is widely reported. So it would give the MiG-29Ks awesome payload carrying capability taking off from a ski-jump.

In comparison the RD-33 Series 3 on IAF MiG-29UPG has a normal re-heat thrust of 8300kgf(same as the old RD-33 engine if I may add) and a Take-off re-heat thrust of 8700kgf - http://klimov.ru/f/download/press-kit/2 ... 100054340/

Based on the diagrams, here are some load-out variations:
  • 11 x MiG-29K (below deck)
  • 7 x Ka-28/Ka-31 (below deck)
  • 7 x MiG-29K (upper deck)
  • 3 x Ka-28/Ka-31 (upper deck)

Total: 18 x MiG-29K + 10 x Ka-28/31

  • 13 x MiG-29K (below deck)
  • 4 x Ka-28/Ka-31 (below deck)
  • 8 x MiG-29K (upper deck)
  • 2 x Ka-28/Ka-31 (upper deck)

Total: 21 x MiG-29K + 6 x Ka-28/31

  • 13 x MiG-29K (below deck)
  • 4 x Ka-28/Ka-31 (below deck)
  • 10 x MiG-29K (upper deck)
  • 0 x Ka-28/Ka-31 (upper deck)

Total: 23 x MiG-29K + 4 x Ka-28/31

  • 12 x MiG-29K (below deck)
  • 5 x Ka-28/Ka-31 (below deck)
  • 8 x MiG-29K (upper deck)
  • 2 x Ka-28/Ka-31 (upper deck)

Total: 20 x MiG-29K + 7 x Ka-28/31

  • 12 x MiG-29K (below deck)
  • 5 x Ka-28/Ka-31 (below deck)
  • 4 x MiG-29K (upper deck)
  • 2 x Ka-28/Ka-31 (upper deck)

Total: 16 x MiG-29K + 7 x Ka-28/31

Roughly, we can estimate the hanger space below deck to hold around 17 aircrafts (MiG-29K and Ka-28/31) and the upper deck to hold around 10 aircrafts comfortably (without disrupting the air-operations by not putting them on the runways).

gents its a total myth spread by pakistani spies, traitors and double agents that conventional steam plants are not efficient/incompatible with the idea of heavy duty catapults. let me present the evidence.
there were no less than *eight* fleet carriers in the USN with steam propulsion plants and operating heavy fighters that used more or less the same type of cat as in the nimitz class

Kitty hawk, Constellation, America, John F kennedy
60,000t empty , 80,000t full load
280,000shp steam plant geared steam turbines, 30 knot top speed
24 Tomcats, 24 a7 corsair, 10 a6 intruder + 4 refuelers, 4 hawkeye, 4 prowler, 10 viking, 6 sea kings = 86 airwing
all had 4 cats

forrestal, saratoga, ranger, independence
60,000t empty, 80,000t full load
260000-280000shp steam plant geared steam turbines
airwing identical as above except replace tomcats with phantoms.
all had 3-4 cats

as you can see Tomcats/Phantoms and hawkeyes were being operated at the heavy end of the airwing. the A6 while being slow could also carry a lot of bombs.

maybe they overbuilt the steam plant a little to account for the cats

NONE of these were austere air defence carriers only. they were all strike carriers expected to see thick of action in the article kola peninsula, norway, soviet far east, GIUK, mediterranean in the event of war.

so we need to convince ourself that nuclear is not a must and a large CV can very well do it.

even the much smaller types like vikrant and minas gerais used steam cats. there is no moon rocket stuff about it if we apply the resources and work on it.

instead of being in over our heads attempting a EMALS, let us get steam cats working reliably first.

carrier costs $2-3 billion and airwing another $1b. there is no point carrying on with this game if we are locked out of being a 1st rate carrier power without cats. instead invest the same money in getting Russians to build a fleet of 100 Blackjacks for us, armed with brahmos-A and nirbhay. enormous strike power. ofcourse fleet air defence will suffer but one cannot have both sides of coin. seek bases in mauritius, develop the andamans....

why do we cry because of some old-school toggle switches and control panels in such iron-sided war horses?

In all the excitement, I would rather punch a sturdy metallic button that frugally says "Panda Fry" than a beautiful touch-screen interface that has a check box for "check if you want launch confirmation mailed to your email id" next to the buttons that says "Submit for Approval" and "customer support"

I dont care how it fries, as long as it serves fry..... :evil:

Singha-saar, steam cats are apparently leaky and break down at sea, due to the abuse from kicking out nearly 30 tons every 30 seconds. Khan carriers has huge redundancies on such systems and sit smug due to the 2 reactors they tote around for steaming up. Their older carriers were steam turbine powered. So they already have steam generation paraphernalia for feeding that.

Vikditty went for diesel and Vikrant-class for gas turbines. So extra steam is an issue. EMALS looks promising in that context - buy from Khan, power it up with electricity fluted from the four LM2500 (throw in one more if need be) and be done with.

That is why I wondered why no one explored using waste heat steam boilers to power the Cats and no one even seems to have done preliminary studies on it.

>> due to the abuse from kicking out nearly 30 tons every 30 seconds

to be realistic thats momentary "top gun" stuff. the peak sortie rate/airframe is very sustained stress exercises (extra pilots, crew, spares, UNREP tankers on standby probably) was found to around 1.5-2/day iirc. around 175-200 sorties/day/supercarrier. so they have 4 cats and thats a huge plus in taking 1 or 2 out of service periodically for minor repairs.
if we have only two cats off the bow onlee, need to be very reliable EM cats perhaps.

but right now the Qa khan appears in no mood to share such secrets.

for serious standup fights vs the soviets, the USN had a strategy of massing together 4 carriers for a huge 360 plane airwing, with maybe a dozen missile cruisers and 20 frigates and 10 subs as "escort" and sending that armada in harms way. I believe thats the mode they exercises north of the artic circle to practice attacks on the kola peninsula which as we know crawls end to end with soviet bases and assets.

Austin, how is the construction of the "Carrier" dry dock (270 by 45) in Mumbai Naval Dockyard going? The contract to Hindustan Construction Company was issued in April 2010 to be completed in 48 months. Should be about halfway now?

if its only 270x45 - means we are downsizing ourself to only ADS1 sized carrier for forseeable future and these things need to earn their keep and handle all carriers.

I would have thought minimum 330m x 70m should have been spec size at some incremental cost, so that 300mx60m carrier could be nicely scoped out.

Unless it is mandatory to have the ADS built & repaired at MDL, there are other places in India where we could do this. Maybe MDL thanks to its location in Bombay is facing space constraints.

Pipava Shipyard is one such yard that boasts of such capabilities ...
http://www.pipavavshipyard.com/drydocks.html

Quote:
The Pipavav Shipyard originally consisted of two wet basins – one approximately 680 meters long and 65 meters wide, and the other approximately 680 meters long and 60 meters wide.

The first of these has been converted into a dry dock measuring 662 meters longs, and 65 meters wide.


need to check if L&T have something similar.

Aircraft carrier project delay to hit naval preparedness Project runs two years behind schedule due to gearbox incompatibility
Quote:
India's project to build a seaborne aircraft carrier of its own has been delayed by two years, raising questions on the Indian Navy's ambition to emerge as a dominant player in the Indian Ocean region. China is also keen to establish itself in this area.

About two weeks ago, the US had announced its new military policy to station more naval assets, including six aircraft carriers, in the Asia-Pacific region.

The Indigenous Aircraft Carrier (IAC), being built at Cochin Shipyard Limited, is facing delay in the installation of gearboxes for the four powerful engines of the 40,000-tonne warship. As per estimates arrived at by the apex committee of the Ministry of Defence (MoD) last month, the warship can now be launched by the end of this year. This will be almost two years behind its original launch deadline of October 2010.

Once the hull of the warship is launched at the sea, the outfitting is likely to take another four years, hence the warship is expected to be delivered to the Navy only by 2016, which is two years behind its original schedule. Defence Minister AK Antony had laid its keel in February 2009.

In January this year, the under-construction ship was taken out of the dry dock and stationed in the waters without some of the equipment that should have been in place.

Sources said one of the gearboxes had been fitted while another one arrived at the yard a few weeks ago. To get it fitted, the ship will have to be taken back to the dry dock. An Indo-German collaboration that supplied gearboxes for the 5,000-tonne stealth warship, INS Shivalik, was chosen in this case also. The aircraft carrier is almost 10 times bigger. The first lot of gearboxes provided by the company was unacceptable and had to be designed afresh.

The contract was to have around 18,000 tonne of the warship ready at the time of the launch, but it is still short by around 4,000 tonne, sources said. The MoD and the Navy have conveyed their displeasure to the shipyard and asked it to get the warship back to the dry dock and simultaneously continue with other works till the gearbox issue is sorted out.

The MoD had allocated Rs 230 crore for the modernisation of the shipyard. Since a modular-style construction has been adopted, it is possible to work on other equipment at another site.

The primary reason for the delay is the highly complex nature of the warship that India is attempting along with its simultaneous efforts to localise production. India is the fifth country attempting to make such a warship, which will have fighter aircraft stationed at its deck. So far, only the USA, Russia, the UK and France have produced such warships. China is re-fitting the one that it purchased from Ukraine after the USSR broke up.

Strategically, this delay will affect the Indian ambition to have two aircraft carriers in its Naval fleet. At present, India has only one, the INS Viraat, which after a life extension, is slated to retire in 2015. It is 50-year-old and the fighter aircraft on its deck, the Sea Harriers, are no more produced now. The second aircraft carrier, the Russian-origin Admiral Gorshkov, is undergoing sea-trials in Russia and is set to join the Indian fleet early next year under its new name, the INS Vikramaditya. In case the IAC is not delivered till 2015 - which is unlikely as per the present status - the Navy will be left with only one aircraft carrier, INS Vikramaditya.

Indian aircraft carrier "Vikramaditya" in the trials in the White Sea has exceeded the required handling characteristics

Quote:
MOSCOW, June 21. (ARMS-TASS). The aircraft carrier "Vikramaditya" Indian Navy (former Russian aircraft carrier "Admiral Gorshkov") this week successfully completes sea trials of the factory in the White Sea. This was reported by Itar-Tass source in the shipbuilding industry.

"Experts" Sevmash ", where the upgraded aircraft carrier, are deeply gratified that during the trial which began June 8 in a sea of ​​running the required characteristics of the spacecraft were not only sustained, but even exceeded," - said the source.

"The ship operates in the test crew of our Navy, on board are also commissioning team, representatives of the" Sevmash "and the officers of Indian Navy," - he added.

The source said that next week, "Vikramaditya", after loading the fuel, water and food to take a course from the White Sea to the Barents Sea, "where he will begin test flights of the deck on a ship-based aviation group decked Russian MiG-29K."

Previously, the spokesperson of the "Sevmash" Anastasia Nikitinskaya reported that "the testing program is designed for 124 days."

A source in the shipbuilding industry confirmed that the aircraft carrier "Vikramaditya" will give the Indian Navy in December of this year.

As previously reported the official representative of the United Shipbuilding Corporation Alexei Kravchenko, sea trials on factory aircraft carrier "Vikramaditya" in the White Sea, "will test the ship's main systems and components, main and auxiliary power systems, communication systems, navigation and others."

the gearbox maker would be Elecon of Pune, who supply and service the RENK gearboxes in India.
they seem to have a jinx. for the P17 also, a truck carrying one such gearbox caught fire and was gutted when the straw packaging caught fire!
this one is a bigger goof up....the LM2500 comes in 3 models. maybe the model on Vikrant and the model they assumed did not match :(

Yes,my point too.The width of the flight deck poses limitations as to ops.The problem is that even IAC-1 cannot launch and recover aircraft simultaneously.It is why a STOVL versuion of the FGFA is an absolute,as it will be easier to operate from our med. sized carriers,cost a couple of billions less having no cats (UK ests),and be cutting edge stealth aircraft,the best that we will have at the time.

With a tanker tugging along this must be a long voyage of the ship with few port visits and refueling at midsea .

The chinese frigate out there ahead of P-17 looks so similar to Indian ship , Shanghai sky line looks good at night.

The takeoff runways are of 140m and 200m as compared to 110m and 170m of INS Vikramaditya. Thus mig29k will be able to take of with higher payload on shorter runway of IAC as compared to the shorter runway of INS Vikramaditya.

Russia completes India’s submarine modernisation programme

The INS Sindhurakshak submarine came off the slips at the Zvezdochka shipyard in Severodvinsk on Saturday, marking the completion of a mid-life refit programme for the Indian Navy’s Kilo-class diesel-electric submarines in Russia.

During a two-year in-depth modernisation the torpedo-firing INS Sindhurakshak, built in 1997, has been equipped with the tube-launched Club-S cruise missiles effective against surface vessels and submarines at a range of about 200 km. It has also been provided with some Indian-made systems, including a hydro-acoustic "USHUS" complex, a CCS-MK radio-communication system and Porpoise Electronic Support Measures. After going through sea trials and firing tests the submarine will be handed over to the Indian Navy later this year.

The INS Sindhurakshak is the seventh and the last of the 10 Kilo-class submarines that India bought from Russia between 1986 and 2000 to have undergone mid-term repairs and modernisation in Russia. Of the remaining three submarines one was repaired in India and the two others are currently under repair in India.

Even as Russia prepares to deliver the last retrofitted submarine to India, Russia’s top shipbuilding official has come up with the idea of a second mid-life repair of the Indian Navy’s Kilo-class submarines.

“A second repair will add another 5 to 7 or even 10 years to the submarines’ scheduled 20-year service life,” said Andrei Dyachkov, Director General of Sevmash shipyard, who is expected to take over as the head of the United Shipbuilding Corporation, which controls 70 per cent of Russia’s s shipbuilding assets, next month. “This will help the Indian Navy maintain its submarine strength in view of delays in the induction of French-built Scorpene subs and in floating a tender for six more diesel-electric submarines,” he said.

The Indian Navy issued Request For Information (RFIs) under the P-75 (I) project way back in 2008. However, it is yet to open a global tender for the submarines. Russia is expected to take part in the tender with its new Amur-1650 submarines, along with France’s Scorpio, Germany’s Type-214 and Spain’s S-80 submarines.

Mr. Dyachkov, who also heads the Rubin Naval Design Bureau, which designed the Amur-1650, thinks the Russian submarine stands a good chance of winning the Indian tender.

“We hope for success and are confident of fulfilling all terms of the tender in the required timeframe,” he told The Hindu.

The Amur-1650 makes far less noise than the Kilo-class submarines, which the NATO nicknamed “Black Holes” for their stealth qualities.

The shipbuilder denied media reports that said Russia was trying to have the demand for the submarines to have onboard Air Independent Propulsion (AIP) system removed from the tender requirements.

“We have designed and built an advanced and safe AIP that generates hydrogen onboard and enables the submarine to stay underwater for much longer time,” Mr. Dyachkov said.

Can the ShiniMaywa be adapted for aerial fire fighting roles? before somebody goes with a non-chalant NO, wouldn't that capability be of great use in coastal places and places close to large water bodies? as the Mumbai mantralaya episode shows, it would have helped even in 26/11 hotel fire fighting, with big high rises being given permission ...

from wiki,

One PS-1 was experimentally modified for aerial firefighling in 1976 with an internal capacity of 7,350 litres (1,940 USgal) of water.

PS-1 is the older version of the current ShiniMaywa

MoD sits on tender for new submarines
http://www.sunday-guardian.com/investig ... submarines

Quote:
Ministry of Defence (MoD) has delayed the order for six additional (second lot) submarines to be bought for the Indian Navy. The decision comes at a time when the submarine fleet is getting depleted. The Defence Acquisition Council last year cleared the acceptance of necessity (AoN) for this Rs 50,000 cr deal, which will lapse in August, before which the tender has to be floated. The contract is for six submarines under Project 75 (I), which are a follow-on of the first six submarines currently being built in the Mumbai-based Mazagon Docks Limited (MDL) by French company DCNS.All six submarines under the P-75 (I) contract are supposed to have the AIP (air independent propulsion) system onboard. The AIP is a technology which allows a conventional diesel submarine to operate without the need to surface and helps it to remain submerged for a longer period of time.Four global vendors are in the fray: Navantia of Spain, Rosoboronexport of Russia, DCNS of France and HDW of Germany. India has been operating Kilo-class submarines of Russian origin and German HDWs and has them in its inventory. The Spanish and Russian submarines do not have the AIP system onboard, which is why, according to sources, Russia is trying to have this clause removed from the tender requirements.Retired Vice Admiral B.S. Randhawa told this newspaper, "Two lines of different designs of submarines were supposed to run concurrently and then an evolutionary design of our own, but there has been a delay and this will affect force levels which are coming down. As AIP only helps in underwater patrols, its efficiency depends on the distance from the operating base and also on the expending stores of a submarine has to be taken into account as the storage capacity is very limited."Already grappling with a shortage of submarines, the Indian Navy is currently left with just 14 submarines comprising 10 Kilo-class and four 209-German HDWs, out of which one Kilo-class (INS Sindhurakshak) has left for Russia for overhaul and modernisation.Under the original six-submarine order, called Project-75 (worth Rs 18,798 cr), French firm DCNS is building the Scorpene at MDL. The project is already facing time and cost overruns. The order was signed in October 2005. The first submarine would be delivered in June 2015 and the last one in the second half of 2018, the Defence Minister said in Parliament last year. The government also sanctioned an additional amount of Rs 4,764.00 cr for the project.Delay in the scheduled delivery was due to initial teething problems, absorption of technology, augmentation of MDL infrastructure, etc., Parliament was informed.

For P-75 (I), along with MDL, there will be participation from the Vishakhapatnam-based Hindustan Shipyard Limited (HSL), which will have a private Indian partnership. Hindustan Shipyard Limited was taken over by the MoD in 2009 to build the indigenous Arihant-class nuclear submarines. L&T is already collaborating with the navy, DRDO and HSL in manufacturing the indigenous nuclear submarines. Out of the six, two will be bought from the original equipment manufacturer (OEM), three will be made in MDL and one at HSL.
