Indian Navy Sticks with DRDO Developed AIP, for Better or Worse!

Scorpene cutaway scale model with DCNS AIP plug at DefExpo 2014

The Business Standard reported on July 20, 2015 that because of delay in DRDO's Air Independent Propulsion (AIP) project, which is almost 4 yr behind schedule, only the sixth Project-75 Scorpene would be fitted with an AIP plug. It is also possible that all six Scorpenes would be built without AIP.

The Indian Navy had earlier asked Mazagon Docks Limited (MDL) to equip the fifth and sixth boats with AIP by fitting an additional 300-t section on the last two Scorpene submarines built at MDL under Project 75.

MDL and French firm DCNS, which developed the Scorpene, are responsible for fitting the new hull section and safely integrating the DRDO-developed AIP plug to the submarine.

DCNS initially offered its first generation MESMA AIP with the Scorpene, but the Indian Navy opted to go with a second generation DRDO developed 300-t AIP based on fuel cell technology.

DCNS has since developed and demonstrated to Indian journalists a fully tested second generation operational-scale fuel cell AIP that would allow the Scorpene to stay submerged for 3 weeks, but the Indian Navy hasn't been swayed from its decision to go with the DRDO AIP.

(Without AIP, Scorpene can stay submerged for 4 days. With a  MESMA AIP, it would be able to stay submerged for 2 weeks.)

DRDO has demonstrated its AIP technology on a land based prototype. Trials on a land based submarine section were to commence from March 2015 and full scale operations of a AIP System was to be demonstrated within 2015.

One good reason why the Navy has stuck with the  DRDO AIP is because it could later be reconfigured for the submarines to be acquired under Project 75I. Also, the four Scorpenes launched earlier could be retrofitted under an upgrade program.

The Navy's penchant for sourcing its systems from within India is well appreciated in the country, but there can be no denying the risk that the Navy is taking by adding to its fleet, in this day and age, new submarines without AIP! India's adversaries, China and Pakistan, have been operating AIP subs for years now!

The following comparison may help readers assess the risk for themselves. Please feel free to your your views through the comments section.

DCNS and DRDO AIPs Compared


The MESMA AIP from DCNS mimcs nuclear propulsion. It uses heat generated through combustion of ethanol (grain alcohol) and stored oxygen at a pressure of 60 atmospheres to power a conventional steam turbine power plant. It doesn't use fuel cells.

The DRDO AIP uses fuel cell technology. A fuel cell converts chemical energy from a fuel into electricity through a chemical reaction of positively charged hydrogen ions with oxygen or another oxidizing agent.

There are many fuel cell types, but the principal ones include the alkaline fuel cell (AFC), proton exchange membrane (PEM) fuel cell, direct methanol fuel cell (DMFC), molten carbonate fuel cell (MCFC), phosphoric acid fuel cell (PAFC), and solid oxide fuel cell (SOFC).

DRDO's AIP uses PAFC, which has some advantages over other fuel cell types. PAFCs offer a broader choice of fuel being more tolerant of fuel impurities. It can operate using reformed hydrocarbon fuels (Methanol) or biogas.

PAFC operating temperatures (150 to 200 °C) are higher and as a result they generate steam as byproduct, besides electric power for propulsion. The steam can be used to meet other heating requirements, pushing up operating efficiency to as high as 70%.

PAFC fuel cells were one of the earliest to be developed and are commercially available of the shelf (COTS).

The only downside of PAFCs is the use of phosphoric acid as electrolyte. However, use of modern materials makes PAFC safe enough for commercial use at hospitals, schools, office buildings, and grocery stores.

It's likely that the DRDO plug uses commercially available PAFCs.

The second generation fuel-cell AIP developed by DCNS usees hydrogen produced from diesel fuel by hydrocarbon reforming.

One obvious advantage of the DCNS AIP is the easy availability of diesel at any port around the globe. The absence of pure-oxygen in the cells allows longer life cycle. DCNS claims that the life cycle of its new AIP plug roughly matches the life-cycle of the submarine, which isn't the case with other fuel cell types.

There is no doubting the sophistication of the DCNS 2nd generation AIP, which has to be weighed against the higher initial cost, high recurring cost from the need to use AIP is all future conventional subs, and the continued dependence on foreign technology. But then DRDO has a well earned notoriety of delays!

Lakshya ToT to L&T


The IE reported on July 18, 2015 that MoD has approved a DRDO proposal for transfer of technology (ToT)  of Lakshya-2 to Larsen and Toubro (L&T) for commercial production.

L&T will pay DRDO a royalty on domestic sales and exports of the PTA. Exports would require MoD approval. Potential export customers include Singapore, Malaysia and Israel.

Lakshya PTA at Aero India 2011

Lakshya ToT to private sector L&T for royalty based sales is a first involving a major defense system. In the past such ToT has been made exclusively to public sector units and with no royalty.

The landmark deal will serve as a model for private sector involvement in marketing, maintaining and upgrading DRDO developed systems, allowing DRDO to focus on R&D.

DRDO Working on Directed Energy Weapon (DEW) Systems


DRDO's CHESS (Center for High Energy Systems and Science), Hyderabad is developing Directed Energy Weapon (DEW) systems.

One of the DEW weapon systems being developed would target UAV's.

On March 2, 2015 CHESS invited tenders for Off-axis concave and convex parabolic mirrors.

The concave mirror is required to have a parent focal length of 2000mm and mirror diameter of 150mm, while the convex mirror is required to have a parent focal length of 200mm and a mirror diameter of 25mm.

In early July 2015, DRDO's IRDE (Instruments Research & Development Establishment), Dehradun invited tenders for supply of High Resolution thermal imager for CHESS platform.

The IRDE tender seeks a Thermal Imager based on Pelican-D 640x512 MWIR IDDCA with 14.5X zoom capability. The Imager is required to have recognition range capability of 5-km against a 1.5m x 3m  UAV target.

IDDCA (Interleaved Double Dynamical Clustering Analysis) is a sampling algorithm based on clustering.

It appears that the imager being sought by IRDE would be used to aim a DEW developed by CHESS for use against UAVs.

Goa Shipyard Limited (GSL) Finalizing Tech Tie-ups for Minesweeper Project


Goa shipyard is negotiating technology tie-ups for building mine sweepers  with South Korean yard Kangnam Corporation and Italian shipbuilder Intermarine. The two firms competed in the 2008 global tender for supply of 8 Mine Counter Measures Vessels (MCMVs) to the IN. The contract was awarded to Kangam but the procurement process was cancelled due to alleged irregularities by Kangam. The MoD has since "nominated" GSL to build the MCMVs with foreign collaboration through a fresh tender.

GSL chairman Rear Admiral Shekhar Mital (retd) had told the press in March 2015, "We don't have the technology. That is why we are going to import it. GSL has a capacity to absorb the technology,"

"We will take minimum possible technology from abroad," he added.

GSL estimates that the minesweepers would have at least 60% indigenous content.

Mittal told HT on July 15, 2015 that the Navy is finalizing specifications for the vessels and GSL should be ready to issue a tender by September-end.

GSL estimates that it will be able to start constructing the vessels in 2018 with the first ship rolling out in 2021.

Russia's Yantar Shipyard Seeks Indian Partner for Make-in-India Project 11356 Frigates


India and Russia have been negotiating a third contract for supply of 3 additional Project 11356 class frigates since 2009.

India has earlier procured 6 ships of the class through two contracts for 3 ships each.

RIA Novosti reported on May 20, 2015 that the Indian government wants to jointly produce project 11356 frigates in an Indian shipyard.

Oleg Shumakov, director of the Yantar Shipyard, told RIA Novosti that the Indian Navy "needed three-four more vessels of that class. Currently, they are examining a scenario to produce such ships at home, of course, with our participation and under our guidance."

Shumakov added, "According to our plan, those ships will be of the same class, but with different weapons. Weaponry progresses non-stop, so, I think, the new vessel will be equipped with something more advanced. However, as for its seagoing capabilities, it will be the same."

According to the Business Standard Yantar shipyard is negotiating with Larsen & Toubro's Katupalli shipyard, at Ennore, Tamil Nadu; Pipavav Shipyard in Gujarat; and Cochin Shipyard Ltd (CSL) in Kochi, Kerala for building the three warships.

Once Yantar formalizes a tie-up, the Indian navy will initiate procurement by releasing a tender.

There maybe an interesting twist to the Make-in-India theme of the additional procurement on account of the Ukraine crises.

Project 11356 ships are powered by 4 x Zorya Gas Turbines in a (Combined Gas and Gas) COGAG arrangement with two FP propellers. The Zorya Gas Turbines are supplied by Ukraine.

Yantar Shipyard is in the process of building 5 Project 11356 warships for the Russian Navy. The ships are in different stages of construction. Three ships have already been fitted with the Ukrainian engines. Kiev, which is at loggerheads with Moscow over the secession of Crimea) has refused to supply engines for the fourth and fifth frigates!

Recently, there were reports in the Russian press that the two ships might be transferred to India. A source in the Defense Ministry told  Lenta.ru that once the ships are in India, Ukraine will have no problems supplying engines for them.

The Indian Navy initially acquired three Project 11356 Talwar Class stealth Missile Frigates (Russian modified Krivak III class) from Shipyards of St. Petersburg in Russia - INS Talwar (2002), Trishul (2003) and Tabar (Jul 2004).

The Navy procured three more ships of the class through a follow-up order for three more Talwar Class Missile Frigates - INS Teg (2012), INS Tarkash (2012), and INS Trikand (2013).

The new missile frigates, built by Yantar shipyard in Kaliningrad, are designed to accomplish a wide range of maritime missions, primarily hunting down and destroying large surface ships and submarines.

The ships procured against the follow-up order differ in their sensor and weapon fit. Most significantly, the new ships feature the vertical launch version of the Brahmos missile instead of Russian VLS Klub.

Negotiations are also underway for the overhaul of the first lot of three ships supplied to the Indian Navy.

Vara Prasad, project director for HeliNa, told the press that the missile was test launched from a HAL Rudra 3 times and it hit the target on 2 occasions.

The target range varied from 4-km to 7-km.

"The observations are yet to be evaluated," said Prasad, adding that these development trials would pave the way for the 'deliverable stage' in the near future.

MoD's end of year report for 2014 states, Helina was successfully integrated with ALH (Rudra) after successful trials.

The missile with capability to defeat futuristic armors underwent successful ground launch field trials in June 2014. It was earlier tested in September 2013
