The Indian Navy is negotiating the purchase of two IL-38 aircraft as replacement for those lost in an air accident in Goa last year. The navy plans to acquire the P3C Orion maritime reconnaissance aircraft as part of its move to modernise its air fleet, said Navy Chief Adm Madhvendra Singh on the sidelines of a function to flag off a naval mountaineering expedition.With an eye on the expertise and maintenance infrastructure for the IL-38, the Navy plans to pick up two planes at second-hand prices. It is also waiting for government clearance for its plans to build submarines with the help of a French firm, Scorpene. Stating that the deal has been cleared by the Ministry of Defence, Singh said: ‘‘It is now between the French and the Indian government to give the final go-ahead.’’The Navy has also invited international bids for two submarine rescue vessels. Singh said it is keen on replacing its fleet of 18 helicopters with anti-submarine warfare capability and medium haul helicopters. The Navy is also waiting for its first Krivak-class stealth destroyer, INS Talwar, which is expected to arrive in June this year. The ship would be put through user trials before it is accepted by the Indian Navy, Singh said. The project was delayed because a missile system failed to meet specifications. India is seeking damages from the Russians for the delay.
