This is India's one of the most ambitious and important defence projects...

The last I read was in IDRW in October 29. It said that design is finalised and keel will be laid in this year.

This news says it was February itself. I am confused

The IN and the ICG love the Dhruv. Especially the Rudra variant for its advanced sensors and weapons package. The Dhruv is thoroughly reliable and was extensively used (still being used ) for SAR off the Western coast recently for Op Sahayam.

But there's a huge issue that prevents it from being used on board ships. The blades don't fold automatically. Deploy kaise karoge?!!!

This article says that Dhruv has been modified to have foldable blades. Please check.

Also, isn't Dhruv too small compared to medium lift choppers?

India needs a bit larger choppers to replace Seakings. Seakings have been a good platform but many officials are calling for replacements. If HAL comes out with another prototype just like they did as Dhruv , it would be awesome.

This is a very old article (2015) what is the current status for a naval version of Dhruv?????

In which weight class does the sea king belong too????

 

[Anikastha]

In which weight class does the sea king belong too????

Medium lift transport and utility Helicopter.

 

[kstriya]

Medium lift transport and utility Helicopter.

And what weight class does Dhruv belongs too??! I am sure the light utility role belongs to HAL LUH which is under development...,

 

[Anikastha]

And what weight class does Dhruv belongs too??! I am sure the light utility role belongs to HAL LUH which is under development...,

Yes , Dhruv is based on light weight Helicopter program. What I say is HAL must kick start another project for multi-role / medium weight copper. Seakings are bit old by now. Better make our own toys. During war re-supplys won't happen that much easily ( I mean spare parts...if enemy gets an info that you are importing spare part from xyz country , he willl lay an ambush . You will lose your money. You won't be able to make that toy fly eventually lose the war.)
We need Medium weight helicopters for Anti-Sub warfare.
Lighter one for special-ops/rescue...etc

And what weight class does Dhruv belongs too??! I am sure the light utility role belongs to HAL LUH which is under development...,

LUH is ultra light helicopter while Dhruv is light helicopter. Sea king is medium helicopter while Mi17 is heavy helicopter. Mi26 etc are ultra heavy helicopter.

LUH is single engine with Max take off weight 3.1 ton. It has 1200kW engine.

ALH is variant of Rudra which has 2 engine of 900kW each and a total take off weight of 5.5 ton.

So, both the chopper have the word "light" in their names but are different

Although the sea king is a superior design of its time, the difference in performance is close to 30% in terms of range & payload, Thr difference can be narrowed down by HAL if an attempt is made, like some additional design changes to accommodate more fuel for range. My suggestion is that Indian Navy can start induction of ALH in ASW role on a stop gap basis till we have the IMRH ready for induction later the ALH’s can be used on other naval platforms or retrofitted for other roles..

Did you see how heavy Sea king is? It has the payload of ASW operations. It is not just about the fuel but about heavy engine. India is making IMRH for the same reason - to replace Sea King and medium lift helicopters. It will take time. From 2004-2014, nothing ever moved on

Delivery of navy's destroyers delayed
DH News Service, New Delhi, Dec 19 2017, 22:48 IST

The first two ships, to be named INS Visakhapatnam and INS Mormugao on commissioning, were released into the water in April 2015 and September 2016, respectively.

Delivery of the Indian Navy's three most modern destroyers is delayed by nearly three years due to a hold-up on the part of foreign vendors to supply vital arms and equipment for these warships.

As a result, the ships that were to come to the navy between July 2014 and 2018 under project 15B, would now be delivered by dockyard between 2021 and 2022, defence ministry officials said.

The first two ships, to be named INS Visakhapatnam and INS Mormugao on commissioning, were released into the water in April 2015 and September 2016, respectively.

Defence ministry and navy officials informed lawmakers that procurement of arms and sensors for these ships have been delayed.

According to the navy's Rs 29,300 crore contract with the Mazgaon dockyard, the four ships under Project 15B were to be delivered between 2014 and 2018. The first three vessels were to be delivered in 2018, 2020 and 2022.

Late delivery of long-range surface to air missile from Israel and its radar (MFSTAR) also contributed to the deferment of the final delivery of the Visakhapatnam and Mormugao to the navy.

In May, the Indian Navy for the first time fired a Barak-8 missile from INS Kochi - one of its new destroyers. It was followed by another firing in November.

With a delay at the supply end, the defence ministry decided to indigenously manufacture some of the items like the sonar system developed by DRDO and the ship surveillance radar, which would be manufactured by Bharat Electronics Limited.

A decision has also been taken to manufacture the main gun of these ships in India, after Italian company Oto Melara was barred from supplying guns to the navy because of the VVIP helicopter scam that involved its parent company Finmeccanica.

Navy’s Rs 2,000 crore order is wind in HSL’s sails


Visakhapatnam: Hindustan Shipyard Ltd has won a contract to build two diving support vessels (DSV) for the Indian Navy, chairman and managing director of HSL, Rear Admiral (Retd) LV Sarath Babu said on Monday.

Talking to TOI, Admiral Sarath Babu said each of the DSVs would cost Rs 1,000 crore. The DSV is used by the Indian Navy to help in emergencies like a submarine sinking, or to provide material to submarines. He said HSL had won the contract through a competitive bidding process.

"We have completed the price negotiations, and expect to sign the work contract soon," Admiral Sarath Babu said.

The first DSV would be delivered within three years of getting the contract, and the second one will be due for delivery within 12 months of the delivery of the first vessel.

Asked whether HSL had the capabilities to build the specialised vessels, the HSL chairman said the shipyard, which was set up in 1941, had the wherewithal in terms of technology and manpower to design, construct and deliver the vessels to the Indian Navy on time.

"For highly specialised technology and labour, we will bring in outside consultants for the purpose, but we will deliver the vessels to the Indian Navy's satisfaction and also on time," Admiral Sarath Babu said.

The Navy contract has come at the right time for HSL, which is struggling to stay afloat as orders for ships dried up several years ago forcing it to depend mainly on ship repairing works to stay in business.

The retired rear admiral said apart from the DSV contract, HSL was also being considered to repair an Indian Navy submarine. "The repair work is for medium-term retrofit and life certification. As part of the contract, we will increase the life span of the submarine's service by seven years," he said.

The submarine retrofit contract is expected to last for at least three years. HSL is expected to get the contract in early 2018. "HSL will now have enough work for the next few years. The only major issue we have to handle is the legacy issue of the company's losses," he said. The company had appealed to the Union government for a financial restructuring package.

If the government approves the restructuring, HSL's negative net worth of Rs 750.51 crore would be erased from its books. In FY 2016-17, HSL posted revenues of Rs 650.08 crore with an operational profit of Rs 38 crore. Operational profit of a company is the profit before interest and taxes.

Cabinet approves Constitution of Indian Naval Material Management Service (INMMS) as an Organized Group ‘A’ Engineering Service

The Union Cabinet chaired by the Prime Minister Shri Narendra Modi has approved constitution of an organized Group ‘A’ Engineering Service, namely Indian Naval Material Management Service (INMMS) and consequent changes in cadre structure of existing Group ‘A’ cadre of Naval Store Officers of the Indian Navy.
