Hope INS Viki will take his participation in next navy day.

Dhruv is very sexy

The lack of modern helicopters is glaring. The Seakings and Cheetaks are obsolete and probably worn out by now. The Navy has work to do.

Dhruv is very sexy

Indeed, this version with the gear retracted looks simply awesome!

Last week a couple of Air Force ones flew past my house !!! Were simply awesome !!

what this the use?

To ditch in sea?

It's just a drag reduction feature for the wheeled version, nothing specific for the navy or so, but it makes Dhruv looks much cooler.

Yes. Apart from some streamlining, its important for the Navalised Dhruv and hence its specific purpose. It provides what is known as "Augmented WPA (Water Plane Area)". This provides stability for the fuselage if the Helo ditches on water and provides resistance to capsizing. This will give more time to the crew and other occupants to escape.
Observe the Westland/Sikorsky Sea Kings too: the main gear is housed in outboard Outriggers. Same Purpose, additionally the Sea King also has a "boat-hulled" underbody to increase that ability even further. These sponsons also allow flotation gear to be in-built whch are inflated by CO2 bottles and increase the survivability.

It wasn't developed for a naval purpose with wheels, but the naval version is based on the wheeld version! At crash landings, the structural strenght of skids are even favourable, because they can absorb more energy of the crash and the emergency floating system will be the main feature for stability after crash landing at sea.
The main advantage of the wheeled version is it's moveability, since you don't need special wheels or tugs to move the helicopter around from the landing spots. That's an advantage at civil airports, small sized helicopters spots and logically also for ship based operations, where the helicopter must be moved from the landing spot to a hangar or parking position.

When we talk about naval specific changes, the emergency floating systems, that is not necessarily added at the normal wheeled varient (used by civil operators, IAF or BSF), the folding tail, or rotors, the winch, or specific avionics for IN or ICG could be named, but a wheeled design is not a naval specific feature. The naval versions of the Eurocopter Fennec, or the Bell 429 remains with skids, just like their land based versions.

Check with the Naviators who fly the Dhruvs and the Sea Kings.
While you are doing so; ask them how different the auto-rotation procedures for them would while ditching over water as over land. You may find the experience enlightening....

As usual, you are claiming things based on your "service", but that has nothing to do with the fact that the wheeled Dhruv version was developed first and a naval version was developed from it. So claiming it is naval specific is just wrong, no matter if you like it or not. Naval specific changes are only those that are not available at the varients for other operators as simple as it is.

Wheeled Dhruv of IAF

Wheeled Dhruv of BSF

Icing on the cake. The first prototype of Naval Dhruv without wheels.
