The second anti-submarine warfare shallow water craft (ASW SWC) named INS Androth was launched at Garden Reach Ship Builders in Kolkata.
It is used to protect the coastal low draft region wherever they are deployed. The first one Arnala was launched last year.
These ships are also capable of full-scale sub surface surveillance of coastal waters and various surface platforms and coordinated ASW operations with aircraft.
These ships are 77.6 meters long and 10.5 meters wide and require a draught of only 2.7 metres. Propelled by three diesel-driven water jets, these ships can attain a maximum speed of 25 knots.
The ship is equipped with hull mounted sonar and a low frequency variable depth sonar, lightweight torpedoes, ASW rockets and mines, a close-in weapon system (with a 30 mm gun) and 16.7 mm stabilised remote-controlled guns.
