| Re: New INS Vikrant Launched Lift size or not one thing is for sure, India needs to move very quick on the acquisition of carrier capable aircrafts. Once this behemoth is operational in an year or two the existing lot of 29Ks are not going to be sufficient to service both the carriers. Any news on this and the aircrafts which will have the honour of the flight from Vikrant. |

| Re: New INS Vikrant Launched I hear the officer Rear Admiral Philipose George who landed the Sea King 42B helo on the Vikrant during the maiden sea sortie has a unique distinction of landing a helo on all the IACs we have had. Quite something! |

* the exception were small Soviet ships such as the Petya's and Osa's which had rather thin hulls that did not take well to our warmer waters. Quote:

Cochin Shipyard must have done regular drydocking to ensure all steel which has thinned out is renewed, (which is a significant cost in itself, plus it is superior steel, which is costlier than regular MS) but that is the point I am trrying to make in the first place. The maintenance and upkeep are capital costs which are not reaping any outcome, just keeping a hull stationary. It cannot be used for power projection, it cannot be used in case of a war. It is money which is stuck, not working for the country. In this day and age of CAD and simulations, there has to be a better way. | |

| Re: New INS Vikrant Launched The beauty of our country is that every drawback, lesson, mistake, error etc. is publicised and discussed. Whether it's delays or struggles in indigenously developing a weapons system or a vaccine. These challenges are not unique, similar experiences are shared by American and other western counterparts when they underwent similar issues. The transparency helps us paint a true picture. Some countries on the other hand are reluctant to discuss this and hide relevant facts (I respect the intelligence on this thread to know who they are, clue: we share borders with a few). For them such news can only be used for the purpose of nationalistic propaganda and any discussion otherwise are met with severe consequences. Eg. when a new oriental aircraft carrier, fighter aircraft, drone etc are revealed, I am sure in the back of my mind that it has a long way to go before reaching complete operational capability irrespective of what 'Gobar Times' says. I am also sure they have had to undergo plenty of short term fixes to overcome many serious drawbacks. As the old phrase goes, 'the proof is in the pudding', but rest assured no one has made a perfect pudding in their very first attempt! |

I believe both the Navy and HAL are committed and working towards a twin engine naval variant, nicknamed the 'TEDBF' or Twin Engine Deck Based Fighter. This proposal is for a canard delta wing, twin-engine, carrier based, multirole combat aircraft. I think the design has been fixed, dimensions ready and a scaled model revealed by HAL. Smarter minds on this thread might have more details. | |

Hull architecture of a AC varies very highly compared to that of other ships. For starters there is a huge cavity (aircraft hangar) on which rests an aircraft deck which has to manage loads (static and dynamic) and momentary loads to the tune of 1000+ kN when an aircraft lands (of course load is distributed) the bracing has to be that much stronger – while also being light enough. In addition to that the hull also has a ‘cantilever’ load to manage (e.g. lifts). This puts additional stress on the hull bracing. In the case of armament, esp. on ships what you see ‘topside’ is literally the tip of the iceberg. Most weapon systems have just the 30 percent you see topside, rest of the 70 percent is below deck. This means factoring for additional loads, clear LOS, non interference,etc. The ship management system was also built in house – a mean feat!. Quote:

The critical thing that we miss in terms of the size of the lifts is that the lifts have to be optimized in line with the overall ship design. Imagine a cantilever load of hundreds of tons which has to be managed even when the ship is moving – add to that a big hole in the side of the ship in all sea states! Additionally, the below deck space is tight! A difference of 1meter – combined with 16 aircraft is 16 meters across, considered a folded size of 8m – could mean the ability to carrying two or more additional aircraft (I am over simplifying this – but just trying to give an example) . Space optimization on a ‘medium size’ carrier will drive a lot of decisions. Some current aircraft (folded wingspan wise) - F/A18 SHornet (8.38m), MiG29K (7.5m), F35C (9.1m), Rafale (10.9m – non folding wings) So, other than the Rafale M, we can accommodate existing all contemporary naval aircraft! The F35 is a tight fit, but I think it is not a fighter we are considering. Quote:

The TEDBF is what the Navy is betting on and with it sharing a lot with the AMCA/ ORCA will mean that there will be a quicker delivery timeline. Having said that we have 45 Mig29 frames. That’s about 3 squadrons worth – and manufacturing is ongoing for the RuN (they are retiring the Su33) – which means that we should be able to buy a few frames with accelerated delivery timelines if required. The VikAd will carry about 2 squadrons when at sea. The Vikrant will carry one squadron plus (when we order it). Considering that the Vikrant will take a couple of years (2022/3) to still see active service I think we have enough to cover both ships for now. Quote:
It is a learning process – IAC 2 will be probably built quicker, maybe enlarged slightly, have different propulsion (CODOG/ CODAG instead of the current COGAG) – making it a better long range cruiser. Note: I am just a student of this subject – if I have made mistakes please do correct me! | |||||||

| Re: New INS Vikrant Launched Sansad TV came out with a short documentary on INS Vikrant, giving a quick glimpse into what's life like inside. It's not on the level of some US documentaries about their aircraft carriers, bit it's still good. |
