OPVs are large craft that carry a crew of up to 80-90 sailors, but are much more lightly armed --- and therefore much cheaper --- than capital warships like corvettes, frigates or destroyers. For performing tasks that do not require heavy fighting, OPVs offer a far more economical option than using heavily armed capital warships.
In contrast to the Rs 825 crore (8.25 billion) cost of each NGOPV, each new frigate that will be built under the forthcoming Project 17A will cost Rs 6,400 crore (64 billion). Seven Project 17A frigates are slated to be built at Mazagon Dock Ltd, Mumbai and Garden Reach Shipbuilders & Engineers, Kolkata.
An NGOPV contract would be a lifeline for private sector shipbuilders like L&T, which has successfully displayed its ability to build OPVs for the Coast Guard at its Kathupalli facility, with the first two vessels delivered ahead of schedule. Meanwhile, the Pipavav shipyard of Reliance Naval and Engineering Ltd has laboured unsuccessfully on an eight-year-old order for five naval OPVs. With delivery schedules long overdue, the first two OPVs are still barely half complete.
In similar circumstances earlier, the navy had slapped cancellation orders on ABG, Bharti and Alcock & Ashdown shipyards.
The navy believes private shipyards are not yet capable of building complex capital warships that incorporate and integrate complex “weapons-and-sensor-suites.”
“These platforms will strengthen maritime security by undertaking a multitude of operational roles both in blue water and littorals. These include seaward defence, protection of offshore assets, maritime interdiction operations and search & seizure operations, surveillance missions, mine warfare, anti-piracy missions, counter infiltration operations, anti-poaching/trafficking operations, humanitarian assistance and disaster relief and search and rescue missions,” said the defence ministry.
“The NGOPV will have an endurance of 3-4 months, compared to just 30-45 days that current OPVs can patrol for. It will have better seakeeping ability (ability to withstand bad weather) and have greatly improved facilities for crew living, given the longer patrols it will be deployed on,” says a senior navy official.
