India will undertake mid-life upgrade of six Russian-made Kamov 28 anti-submarine warfare helicopters besides overhaul of another four.

Of the ten Kamov 28 helicopters that were procured from the erstwhile USSR in the mid-80s, only a few are in flying condition today while the remaining have been mothballed for spares.

The Defence Acquisition Council on Saturday cleared the proposal for the upgrade of the helicopters in Russia, defence sources said.

Under the mid-life upgrade, the six choppers will get new sensors among others while the rest four will only undergo engine overhauling.

The project, to be undertaken by Original Equipment Manufacturer (OEM) Rosoboronexport, is valued at nearly Rs 2,000 crore.
