NEW DELHI: Private shipyard Pipavav is facing a stiff penalty from the Ministry of Defence over a significant delay in the production of naval patrol vessels, a Rs 2,500 crore project that was signed in 2011. A top naval officer told ET that the Naval Offshore Patrol Vessel (NOPV) project is running almost 18 months behind schedule and that the ministry could take penal action as per the rules.

The NOPV project was the first ever Indian warship construction project that was handed over to the private sector and the first of five vessels under the plan was to be delivered by early this year. However, due to multiple reasons - one of them being a midterm change in the foreign design partner - the first vessel is now expected to arrive by June 2016.

Navy's Controller of Warship Production and Acquisition Vice Admiral AV Subhedar confirmed to ET that the delay has occurred and as per the new timeline, all five vessels are to be delivered within a two year period starting June next year. A senior Navy officer said that the delay is likely to incur a penalty from the Defence Ministry as per the rules. The penalty would however not exceed Rs 125 crore. Despite attempts, Pipavav did not respond to queries on the matter that were sent by ET. Reliance Infrastructure which has recently acquired the shipyard did not comment as it is yet to take over the management of the company. The defence ministry is also believed to have made queries on the new ownership pattern of the shipyard as it is presently undertaking a military project.

Sources said that the NOPV project - the first naval order to be won in a competitive bidding by a private yard - has run into trouble due to a delay by Pipavav in finalizing a design partner. While a contract was initially signed with a Russian firm, negotiations broke down over differences on pricing and was terminated.

No Follow-On Orders For Scorpene Submarines

NEW DELHI: There will be no follow-on orders for the Scorpene submarines under Project 75, Indian Navy’s Controller of Warship Production and Acquisition Vice-Admiral Ashok Subhedar declared on April 16, 2015 in New Delhi.

He said the effort in Project 75 was focused on adherence to the revised deadlines for the delivery of six Scorpene submarines under construction at Mazagon Docks Limited (MDL). The first of these submarines, named Kalvari, was recently undocked from MDL and moved on a pontoon to the Navy Dock for further fitment.

After a four-year delay, the Kalvari is finally scheduled for commissioning in September 2016. The subsequent five Scorpenes are to be commissioned successively after nine-month gaps.

It is not yet clear how the Navy will make good its requirement of 18 conventional submarines under the 30-year submarine building plan. Of the 24 originally approved for construction in 1999, six have recently been earmarked to be nuclear-powered boats (SSNs). While the Scorpenes under Project 75 will provide the first six, a new tender under Project 75 (I) for another six conventional diesel-electrical submarines is in the works.

The Vice Admiral said the report recommending a shortlist of Indian shipyards for this Project would be submitted to the Ministry of Defense by April-end.

Subhedar heads a seven-member multi-disciplinary committee appointed to identify Indian shipyards, which can be invited to bid for the Project 75 (I) tender, worth over Rs.50,000 crore ($8 Billion), in collaboration with foreign companies.

"Over the last three months, we have visited all shipyards. We're hopeful of submitting our report to the Ministry of Defense by end-April," he said.

Land based Prototype for Air Independent Propulsion (AIP) System : This is a land based prototype for fuel cell AIP for submarines. It aims to package the AIP plant sub-systems, reactant tanks and waste tanks inside the simulated hull section of the P-75 submarine. The system has in-situ provisioning of hydrogen through hydrolysis of borohydride and oxygen through liquid oxygen. The design part is completed and pre-production floor model has been tested. Hull model has been integrated and is under trials

The Advanced Light Torpedo (TAL) Shyena is the first indigenous advanced lightweight anti-submarine torpedo of India, developed by Naval Science and Technological Laboratory of the DRDO and manufactured by Bharat Dynamics for the Indian Navy.

Shyena is a processor based torpedo which incorporates solid-state electronics, digital technology and has been equipped with an integrated Active/Passive sensor package for multiple search patterns. It is designed to be capable of launching from both a helicopter or from a triple-tube launcher from ships. Its key design feature are maneuverability and ability to transition from warm to cold medium to ensure a hunt and kill.

I am aware that we are using pump jet propulsion system in our surface boats. Can't say the same for underconstruction subs.

Navy League 2015: Boeing developing kit to upgrade Harpoon missiles for extended range

Key Points

• Boeing aiming to double the range of its Harpoon missile
• Harpoon Next Generation will consist of a fuel-efficient engine, additional fuel, and a 300-pound class warhead

Boeing is developing a kit to upgrade existing Harpoon Block II missiles for extended range, in the hope of attracting interest from the US Navy's (USN's) new frigate programme, officials announced on 14 April.

Called Harpoon Next Generation, the new version would include a more fuel-efficient engine, additional fuel, and a smaller 300-pound class warhead, company officials told reporters at the Navy League Sea-Air-Space symposium in National Harbor, Maryland.

"We're looking at doubling the range of Harpoon from 67 nm to 134 nm," said Jim Brooks, director of cruise missile systems weapons programmes for Boeing Global Strike Weapons and Missile Systems, a division of Boeing Defense, Space and Security.

Existing customers, such as the USN and 27 international partners, would be able to upgrade their Harpoon Block II inventory with the kit, which could be supplied to a customer's depot for installation, or the customer could opt to have the kit installed by Boeing.

So far, the company has delivered 7,500 Harpoon Block II missiles, and the USN's Naval Air Systems Command (NAVSEA) let a contract to Boeing in 2013 for the production of 40 Block IIs.

According to USN data, the unit cost for a Harpoon Block II is USD1.2 million. Boeing officials said the cost to upgrade to the Harpoon Next Generation is competitive, and that customers can choose to retrofit their existing inventory or opt for the new missiles to be built from scratch.

"A new Next Gen would be approximately the same [cost] as for one of our Harpoons," said Brooks. "A retrofit would be half the cost of a new missile."

Offering up an extended range capability for Harpoon at an affordable cost has been a driving force behind the upgrade kit, officials said.

"It's really looking at leveraging that installed base of existing Harpoon," said Beth Kluba, vice-president of weapons and missile systems for Boeing Military Aircraft. "That's one of the key affordability tenets we're offering with Harpoon Next Generation."

Officials noted that the Harpoon missile system has proceeded through 10 upgrades over the years, with concerted effort focused on the front end of the missile with improved guidance capabilities, navigation, and seeker capability. Brooks said that while Harpoon Next Generation is considered the next logical upgrade in the missile's evolution, its improvements are focused on the back end of the system; adding more fuel, moving to a more fuel-efficient engine, and bringing in a lighter warhead to compensate for the increased fuel load.

The kit is expected to be ready in 2018, officials said, and the team is working towards a possible demonstration of the improved missile in 2016 for the USN.

A ground test of the back half of the missile in 2014 proved that the kit could double the range of the existing Harpoon, officials added. For the test, the team installed a high-efficiency turbo jet engine in the missile section as well as an expanded fuel capacity system, as a representation of Harpoon Next Generation's full fuel system volume.

I does. The CGI looks pretty much the same though, wait and see I guess.
