The Cabinet Committee on Security (CCS) has approved purchase of five new Russian-made Kamov 31 early warning helicopters for the Indian Navy. The choppers,fitted with an airborne,rotating radar that can track multiple targets in air as well as on sea surface,will join the existing fleet of nine similar helicopters that were purchased earlier. The CCS has reportedly also cleared and approved financing of some key infrastructure projects,including a major irrigation project,along the Indo-China border,a day before border talks commence between the two countries. The government was initially planning to seek a loan for the irrigation project but is now understood to have decided to self finance it.
