Who designed arihant ?!

ARIHANT is not ssk it is ssbn

It's a submarine , isn't. It ?
If they can design arihant , they can design a ssk also
A conventional submarine too

Now even indonesia has also started developing their own Submarine but here we keep giving out RFI for imports.

Navy Submarine design Bureau is full of third class reserved chutiyas who even failed to design midget Submarine. Better fire them all and do fresh hiring of competent people.

We don't fully have submarine design capability on our own but we could always ask for consultancy from foreign sub designer. Navantia, Naval, Fincantieri, Daewoo and other would love to do that for some money yet here we are. BTW Arihant and S5 class are both Russian design, not ours.

Lol aa gaye PKS blog waale did Russians specially told you this ,the hydrodynamic Model of SSBN was seen in NSTL.

Do u know how does conformal antenna works , i mean if the radiating element is any of these aesa array ,so will they just cover it with a conductor sheet shaped to blend with surface or some different mechanism ?

Similar like normal anteena , but the controlling microprocessor is little bit of complex , they must adjust for the varying length and phase of the circuit. For that the phase shifter and microprocessor must adjust . The phase shifter focuses the radar waves infront of the Conformal Anteena and produces strong signals. Each Conformal Anteena is for working differently but the principal is same. The design is based on the structure and shape of the Mother Aircraft , UAV Missile or anything other. It is same for both radiating and receiving Anteenas . And the Aerodynamic loads on the Anteenas also diminishes the performance.

Eventhough Conformal Anteenas increases the Stealth features but there are many features of the antenna that can contribute to the RCS of an aircraft. These include the
shape and geometry of the anteena outerline( u know every stealth fighter uses Zigzag shape), orientation of radar reflective structure including that buried below radar transparent structure, orientation of discontinuities in the skin (panel joints,
fastener holes and external mountings) and the material properties of external surfaces. These factors mean that simply replacing protruding antenna with Conformal Anteena is not sufficient for a LO/VLO Aircraft.

It works better in UHF/VHF bands

So what's the next step in this field ?

No this is a Soviet sub , I forgot the name

Better performing radiating elements for even at high speeds, shape changing anteena for shape memory alloy etc etc

I believe this was the initial design of borei class. Read in some Russian blog.

Now as per the PKS (in the link shared), he says Russia junked initial design as it didn't have more vls and took borei-A design.

So we took this as per him
