DRDO Technology Demonstrator Vessel (TDV)

HSL did steel cutting for Submarine Support Vessels indented to host the DSRVs in future, few weeks ago i think.

And now that we are actually coordinating with USN to keep a tab on Chinese Subs in IOR, i think, this will be our contribution to help maintain the underwater sensors which US has/may have in IOR.

Now that reminds me. Didn't the Japanese offer help to set up deep undersea sensor network(I think it was called the fish-hook system) around the seas surrounding the Andaman & Nicobar Islands sometime back ? What happened to that ?
 
So the fog clears..........a bit.

Technology Demonstration Vessel or ATV-2 : January 2020 Update and Images

January 2020 - TDV is either a missile tracking ship or a naval radar test-bed

With Vikrant getting all the attention, the TDV was conveniently ignored. I received these pics today and I was surprised to see a weird structure (pointed by a red arrow) on the TDV. It's clearly a support structure of a radar array i.e. this is where the antenna of a radar goes. It's significantly larger than the two similar structures present on the Vikrant, also visible in both pictures. While it's clear that it's a radar ship, the presence of A-frame indicates that this ship could be stationed downrange to assist debris recovery. Dr. Y. Srinivasa Rao is the project director of 'Ship No. 20', he is scientist-G at Research Centre Immarath, DRDO, Hyderabad. He is also associated with Program-AD (PGAD) i.e. Indian BMD.

I previously identified the photo above as LB-MFSTAR. But it is possible that it might be our own design and just happens to look like the MF-STAR. The ship above is clearly going to carry the LRMFR :

Something/someone was there recently and it was in news indirectly couple of times just in last two months. Let's wait for official confirmation. Thank you.
 
India’s technology demonstration vessel receives new radar as it nears completion

Kerry Herschelman, Washington, DC - Jane's Navy International

A technology demonstration vessel (TDV) being built for India’s Defence Research and Development Organisation (DRDO) at Cochin Shipyard Limited (CSL) has been fitted with a housing for a new type of dual-panel long-range radar system.

There is limited publicly available information on the radar, but details on the sensor, known as the Long-Range Multi-Function Radar (LRMFR), emerged in 2016.

Indian sources have described the radar as an active phased array radar with a range in excess of 500 km. Like the Elta MF-STAR, it features octagonal faceplates that are approximately 5.5–6 m in diameter.

The TDV project was contracted on 11 August 2015 with a value of INR3.65 billion (USD50.2 million), and this was subsequently increased to INR3.9 billion as the scope of work expanded.

But on the same shipyard. Did IAC-1 get Selex RAN-40L though ? :(

That is a volume scan radar isn't it ? For ATC and AD situational awareness purpose. This one is a domestically designed and made AESA FCR with secondary AD and other uses. Also the LRMFR is still under testing.

I know. It's still not clear about Selex after the ban.

DRDO project 20 ship / DRDO technology demonstration vessel details -connecting the dots

LR-MFR ( long range multifunction radar ) and SLS ( ship launch system ) launchers for supporting the launch of AD series interceptors ( and other missiles if required ).
