BS reported that although the craftsmen from Garden Reach Shipbuilders & Engineers swarm over what will be the Indian Navy’s most high tech stealth warship, Project 28 is two years behind schedule.
The first corvette was to join the fleet early next year. Business Standard discovered, during a first ever media visit to this secretive project, that it will be delivered only in June 2012. The other three corvettes of Project 28 will follow at one year intervals.
The major reason for the delay the Indian Navy has stipulated such unprecedented standards of stealth for every piece of equipment on board that suppliers have struggled to develop engines, transmission, air conditioning and power-generating systems that work silently enough to meet those requirements. Furthermore, the navy mandated that Indian suppliers would provide much of that equipment.
The Project 28 corvettes are 2,500 tonne warships that will protect Indian Navy battle groups and coastal installations from lurking enemy submarines. In the deadly cat and mouse game between ASW corvettes and submarines, the stealthier vessel is usually the winner, detecting and destroying its opponent after sneaking up undetected. The challenge of Project 28 has been to minimize vibrations and noise from the ship’s machinery, propellers, and from water swirling past the hull.
Success has come late in developing some of this equipment. The Kirloskar group has delivered the engines, albeit after a delay. Earlier this year, DCNS of France supplied the Raft Mounted Gearbox, which almost completely suppresses noise from the power pack. But Wartsila India is still struggling to reduce vibration in the four diesel alternators that will power the corvette’s electronics.
Once all this is in place, six huge spaces will have to be cut open in the corvette’s hull, through which giant cranes will lower monster-sized equipment like the 65 tonne engines. Then the hull will be welded shut once again.
The Navy chief Admiral Sureesh Mehta told Business Standard the navy had carefully laid down stealth standards that were absolutely necessary in war. Admiral Mehta explained that “We cannot compromise operational requirements for suppliers who are having difficulties meeting standards. We cannot come second in war.”
Rear Admiral M K Badhwar said that the navy is determined to nurture an Indian supplier base, to develop increasingly high-tech products for warships. He points out that “Initially, they had real problems in meeting the sophistication levels that we were demanding. But we insisted and now most of them have done so. This is vital for an indigenous shipbuilding industry.”
All this has taken the cost of Project 28 from a sanctioned INR 2,800 crore to an estimated INR 7,000 crore now. This is approximately in line with cost increases for previous Indian-built warships.
The Project 28 corvettes when they join the navy’s fleet will be silent and heavily armed. An Otomelara Super Rapid Gun Mount on the bow can pour 76mm shells onto aerial and surface targets. Flanking it will be two Indigenous Rocket Launchers that can fire at both submarines and ships. Submarines can also be engaged through six torpedo tubes. Two AK 630 Gatling guns, one on either side, can shoot down attacking aircraft. Finally, vertically launched missiles are likely to be mounted for engaging surface targets.
