INS Anjadip commissioned
One line
The Navy commissioned INS Anjadip, the fourth anti-submarine warfare shallow-water craft designed for coastal operations.
Summary
Littoral waters are noisy and shallow, which complicates submarine detection. Specialised craft combine sonar, weapons, speed, and local manoeuvrability for harbour approaches and coastal sea lanes.
