The Indian Navy recently launched its most advanced and state-of-the-art anti-submarine warfare shallow watercraft (ASWSW), named Amini. This is the fourth in the series of eight ASWSW being built in India by domestic shipyards for the Indian Navy. Earlier this year, four of these ships were launched, each with more than 80 per cent indigenous content. The ASWSW is 77 metres long with a displacement of 900 tonnes, a maximum speed of 25 knots (46.3 kmph) and an endurance of approximately 1,800 nautical miles (3,333 kms). These vessels are designed to undertake anti-submarine operations in coastal waters, low-intensity maritime operations and mine-laying operations.
