... they concluded that they would do more harm then good - because of the tight space they would have to sit close to aircraft engines and their angle to deck would have to be low (something like 45 degrees) . Furthermore , plane would have only few seconds in after-burning mode before take off (there is only so much heat deflectors could handle ) . On the other hand , without deflectors jet stream would simply go overboard and not towards people and other aircraft.

The discussion about deflectors not being adequate does not make sense to me. Clearly, they can be designed to be adequate with the proper material and angles. There is room on the Virkamaditay to install proper deflectors, but there would also be a cost. Of course no one would install an inadequate deflector, it would make no sense.

They just did not believe it was worth the money it would take.

Behind those two launch positions (both of which can be seen in the photo below), there is ample deck space, catwalks along the side of the carrier near the outboard position, but there obviously will be no aircraft parked behind either without a deflector. That's the point. Where they might have spotted additional aircraft, there will be zero chance for that now.

Goa-Shipyard-Hands-Over-Second-NOVP-to-Indian-Navy.jpg

INS SARYU CLASS NOPV
​

World Maritime News said:
Goa Shipyard Ltd. (GSL) on Monday handed over the second state-of-the-art Naval Offshore Patrol Vessel (NOPV) INS Sunayna to the Indian Navy.

Rear Adm (retd) Vineet Bakhshi, VSM, chairman and managing director of Goa shipyard handed over the vessel to Cdr Aftab Ahmed Khan, commanding officer designate of INS Sunayna during a ceremony in Goa, reports the Times of India.

This 105 meter vessel is the second in the series of four new class NOPVs designed and built by GSL for the Indian Navy. The vessel is suitable for monitoring sea lines of communication, defence of offshore oil installations and other critical offshore national assets. Besides, the vessel can be deployed for escorting high value ships and fleet support operations.

INS Sunayna is powered by twin diesel engines and fitted with state-of-the-art Navigation, Communication and Electronic Warfare Equipment. One 76mm SRGM two 30mm CIWS Guns with fire control system together with six Chaff launchers form the main weapon package of the vessel. Sporting a flight deck, the vessel supports embarkation and operation of a multi role helicopter.

The vessel accommodates 8 officers and 105 sailors. With 25% reserve fuel capacity and an extended mission duration capability of 60 days, the vessel is designed to operate all year round.

Very nice Offshore Patrol Vessels the Indian Navy is receiving here. Not major combatants, but good enough to relieve current frigates and other combatants of thee lighter duty. And with their embarked helo, capable of assisting in ASW activities too.

I found some deck schematics on globalsecurity.org for INS Vikramaditya , I do not know are they reliable , I will assume they are . :D

Looking at the back launch position , it is clear it would be main launch position . It is placed very close to the edge of the deck , to maximize take-off run and increase possible payload . Now , I suppose you could squeeze deflector somewhere there , but what would be the point ? Sole purpose of deflectors is to put something behind them and there is no place on Vikramaditya to put anything of value behind back launch position .

As for front launch position , it could use deflector . But again , I'm guessing it wouldn't be used much operationally . Take-off run is to short , it could only support Mig-29K with let's say 4 AAMs and 50% fuel . That means it would be only used in emergency (unidentified bogey approaching fast and there is no one to intercept) . I guess they concluded it would not be worth of trouble , considering what they intend to do with that carrier (i.e. launch air strikes on targets without much air support , and intercept occasional patrol aircraft ) .

No need to rely on schematics. Here's how she looks at sea.

BTW, this picture is shown on this thread just a few posts earlier than our current discussion.

Aircraft could be spotted behind the outboard position, but would be in jeopardy of the jet blast. So they could use a blast deflector there. Admittedly only a couple of aircraft and only the front or rear portion of those aircraft (depending on why they were spotted there) but on a deck where space is such a premium, every inch helps.

Then we have the launch stripe running down the center and ending near the middle of the Island (which is clearly a second launch point the Indians established, not shown in the older schematics), that position clearly could also use a jet blast deflector for anything behind it, particularly so close to the Island.

Maybe the Russians wanted to rip the Indians off with grossly overpriced jet deflectors that they decided to install them themselves. ;)

Not sure if it's because of the smaller size of the carrier or the planes or smaller angle of the ramp, but I feel that Mig-29 requires a longer take-off run compared to Su-33 despite being smaller and lighter.

New video of INS Vikramaditya (from 4:10 ) including some night (evening :D ) ops from 7:02 . Location of launch position is shown on 05:51 and 07:12 . Indian sailors steering ship at 07:21 .
