Fairly sure the MIG's were included in the price, but even if they werent, 2.3 Billion is still half the price of a new carrier of similar size like the Queen Elizabeth class.

2.3 billion was the ship and refit - migs were another 1bn on top. So, no, 2.3 billion for a ship that was over ten years old when deactivated and which sat a further eight years as scrap.

It's also 2/3 the displacement of a QE. I'm finding it very hard work to see this as anything other than a total feckup in procurement.

It was most definetly a bad deal in the long run, If India had started construction of a carrier in 2001 when gorshkov dicussions started, then we would have had a functional carrier now to take over from viraat.
However cancelling the deal now wouldn't be smart either because then the navy would be without a carrier once viraat goes out. Wish people had more forethought back then.

Also as is typical with any Indian Defence procurement the needs/expectations/additions on the AC kept changing from the Navy. Plus the russian initial estimates on the condition of the ship and the amount of rework to be done was also wrong.

Currently its on track and this week there was an announcement reported from the shipyard tht the Ship will be handed over to the IN in Dec of 2012.

India was not technically strong enough to start carrier construction in 2001, the basic infrastructure needed for a task of this complexity was missing from Indian shipyards.

true true, but right now only 4 Otobreda 76mm guns have been confirmed, which is kinda surprising because they have a relatively slow RTF when compared to the PHALANX or other Gatling-based point defense systems.
Has India indicated any interest in Oto Melaras guided munitions?

And a 76mm derivative of the Vulcano range of guided rounds has just been announced.

India could have started construction in a foreign yard (Italy would seem to be a good choice), with Indian personnel being seconded to learn, & by now the IN would have a new carrier in commission, with a second building in India, & probably more advanced in construction than Vikrant (ain't that what the ship building at Cochin is called?). In a few years the IN would have a class of two ships in service, one foreign-built with Indian involvement, a second Indian-built with foreign assistance, with the advantages in logistics & crew training (particularly for cross-decking) of commonality, & be able to build further ships unaided.

10 years back fixing Gorshkov was a similar idea, lets get an aircraft carrier quick until the shipyards back home muster up the technology to do so :).

Anyhow I have a feeling that the next aircraft carrier project might not be handed to CSL. There are now two major private sector shipyard, Pipavav and L&T. Pipavav already has a JV in place with Mazgaon Docks Ltd and L&T has already had experience with Hindustan Shipyards on the Arihant class submarines. Both of these shipyards are among the largest shipyards in the world and have the latest technologies. What they don't have much experience in is integration of military systems on to the ships, and that is where the expertise of CSL, HSL and MDL would be needed. Now L&T might not be that big a name outside India, but when it comes to heavy engineering in India, there is no conglomerate that even comes close to their performance. The turn around time on L&T projects is impressive, almost every project they handle is delivered before time, and this is how they make a profit by reducing their overhead costs. Next 15 years are going to be interesting times for Indian shipbuilders with 25-30 submarines, 1 or 2 aircraft carriers and dozens of frigates, destroyers and support ships to be made :)

But an extremely ill thought out one. The condition of the ship wasn't ascertained prior to starting work, so it was not known if the contract was achievable. There was obviously no provision made for a follow-on second in class, which would have been the logical way to transfer skills gained assisting in construction, & I've not been able to discover any real, useful, provision for transfer of skills via secondment of Indians to the build.

Fincantieri or DCNS, on the other hand, could have built you a carrier which you could then have built a second & maybe third of class of.

Gorshkov will always be an orphan, a unique ship with technologies no other IN ship still has.

That is...ASSUMING, this rebuilt, grafted on ski-jump lump DOES actually work! DFO ;)
Why wouldn't it? There's anough material available from multiple ski-jump users to work out the parameters - on top of which they would have simmed this before cutting and welding metal.

the ramp would have been crunched against the actual tech parameters of the aircraft (ie not Janes public domain material). eg IHS (Janes/Lloyds) provides multiple levels of detail to clients, there is public domain, Janes Naval etc.... and then there's the classified material which is only released to Govt agencies.

I seriously doubt that they would have grafted anything on as it would have to be simmed to not only deal with launching aircraft but also factored into to ship handling requirements which would also impact on the CONOPS not only for the carrier but also on accompanying escorts....

ski jump

Take a good look at public photos of that ski-jump: instead of smoothly "fairing" the shape-on sides-into the hull, it has a "ledge" at its bottom that appears to jut out 6-12inches; should be wonderful in heavy seas?? DFO :rolleyes:

the issue is about relevance of the angle and how the overall shape impacts turning into the wind etc...

I'd be less concerned about the issue of final join up of hull mods to new and more concerned about issues of uninvited lift.

without understanding or knowing the design requirements and/or constraints given to the maritime engineers I'm unable to give qualified comment.

aesthetics don't come into it. the CONOPs and absolute technical performance issues that inform the CONOPs are the primary issues. I would seriously doubt that the engineers did not have access to the approp design data, sim data and tank tests.

if they did and they designed around those three core elements then the aesthetics are academic

functionality

Actually, as an Industrial Designer, I'd consider that grafted on ski jump to be what I would term FUNCTIONAL aesthetics (or lack of...), given what heavy seas can do to mere steel.
For example, when the USN did the various SCB 127 mods to the Essex class CVs, including the enclosed hurricane bows, function was the driving force behind smoothly fairing the new bow shape into the existing hull. Also, given the sleek hull forms Soviet/Russian warships typically have, this "tacked on" approach seems strange for them. Given the modified carrier was "FREE", I guess to much shouldn't be expected!!

Even tho the CLG Kerch was not a carrier, this view certainly shows what seems to be their normal approach to hull design. DFO :D

I've worked on a variety of weapons, systems and platform programs over the last 30 years, both in govt and in the private sector as a consultant/contractor. functional aesthetics has never come into it. OTOH, the push in the last few years has been Human Factors, which takes functional layout considerations into how operators use the gear - but whether its pretty or not is not an issue. It's about form and function. The days of grace and form probably died with the US and Russian maritime engineers/shipwrights with the last of the clippers. (battleships/battlecruisers/cruisers)

CREF above. I can tell you that aesthetics is the last design priority, the notion that if it "looks nice" then it "fights nice" basically died in the 70's

Human Factors design elements are far more important than functional aesthetics - esp in contemp platforms and weapons systems.

In fact I call on military scientists to assess HF, I never call on industrial designers to tell me whether a combat system looks nice, or whether a platform looks nice.

Its all about practical benefit in its operational environment.

ergonomics

Yes, I'm well aware of ergonomics (Human Factors) as I have worked those into every design project that had any need for them for 38+ years. Many times though expieranced Engineers didn't have a clue as to what I was talking about! DFO :D

Human Factors is not about ergonomics though, ergonomics is part of the evaluation structure in HF, but its only a small component.

I haven't seen too many industrial designers or engineers who understand what it's meant to establish in a military environment.

in fact I've seen quite a few commercial entities now start to call on military HF analysts and contract them in. Entities like DARPA, DSTO. Qinetic, SAIC are the kinds of shops where HF analysts/specialists exist. Ergonomic analysis tends to be seen as a sidekick to OH&S in most of the private companies I've dealt with.

Its not just about "people are familiar with green as on or go so dye the start button green, make it big enough for someone with gloves to use and make sure that we design all gear to have the big green start/go button in the lower right hand quadrant of all our equipment so as to build in associated familiarity" etc.....

Meanwhile BACK to the subject of the carrier...has anyone seen newer photos of her? DFO ;)

The issue of HF and design directly related to the discussion on the carrier.

Part of my job as a Mod is to is to manage the debate as well as assist in providing technical detail and accuracy where approp. :)

Sorry it is not simply down to shape and other ships with similarly flared bow strcutures can manage quite well. A flared bow has the advantage of providing a massive increase in bouyancy a the bow dips limiting the risk of drivng the bow in.

This does increase the risk of slamming in very severe conditions but there are structural solutions (frame spacing, plate thickness, panting frames etc) to deal with this combined with 'semanship' precautions. If the vessel is slamming badly you will not be flying and a reductions in speed and/or alterationof course are useful tools to mitigate the ris of damage.

I not the comment with regard to the step. Depending on how this has been achieved structuarlly it may not be an issue. It is appropriate to presume that this will be bad in heavy weather unless you have access to the design of the bow structure and how the elements are connected.

I agree it is ugly........ does not mean it will not work or will be weak.

Sorry to come in again so soon but I am reading through the thread. Sorry HF is not ergonmoics, athough this element of design does play a part in some contributory mechanism. As noted in the paper below, HF, cover a very broad range of issues that lead to risk to safety or adverse performance.

Human factors identifed by the NTSB include

  • Fatigue (where there is an ergonmics element)
  • Inadequate communcations
  • Inadequate general technical knowledge or knowledge of systems
  • Poor design of automation (again this has an ergonomics element)
  • Decisions based on poor or inadequate information
  • Poor or inadequate standards and/or procedures and practices
  • Poor maintenance
  • Hazards in the environment (including heavy sea ways and protection of crew)
to suggest HF is just ergonomics is quite wrong and as noted by GF this is a broad area of consideration.

The discipline of human factors is devoted to understanding human capabilities and limitations, and to applying this information to design equipment, work environments, procedures, and policies that are compatible with human abilities.

Perhaps they got their ergonomics confused with the Human Factors:

Sea trails of upgraded aircraft-carrier set for 20122011-09-28




Indian navy and Sevmash shipyard agree that it will be inappropriate to start testing at sea with “Vikramaditya” this November as earlier scheduled.
Russia and India agreed in 2004 to upgrade and sell the former Soviet aircraft-carrier “Admiral Gorshkov” to the Indian navy under the name “Vikramaditya.”

After years of delays and disagreements between the two countries on the final price tag, a 2010 agreement stipulated delivery of the modernized vessel for December 2012. But, first the Indian crew will take the vessel out in the Barents Sea for testing. That was supposed to happen this November.

New date for sea trail of the huge aircraft-carrier is now May 2012.

The vessel is now 85 percent ready, reports the portal of the Sevmash shipyard in Severodvinsk following delegation of inspections of the Joint Staff of the Indian Navy.

- Today, the works are on schedule, but there are technical problems can be solved largely through Rosoboronexport, which always supports us. I am sure that in December 2012, the ship will be delivered to the customer, President of JSC United Shipbuilding Corporation Roman Trotsenko, says in the press-note posted on the portal of Sevmash.

oh my, another delay...........DFO :eek
