A minor fracture in the casing of a key sensor has forced the Navy to dry-dock warship INS Betwa for repairs, sources said here on Wednesday.

INS Betwa, a Brahmaputra class guided missile frigate, had returned to Mumbai from an operational deployment in the Arabian Sea when the ship’s crew noticed that the sonar (Sound Navigation and Ranging) system had a sea water ingress.

This forced the Navy to send the warship for dry-docking and later found that the casing of the sonar’s dome had an hairline crack.

Now, the Navy is getting the Sonar either repaired or replaced, sources said, adding that it was also investigating how the dome got damaged.

Sonar is a sensor that enables the warship to send out sound waves to detect depth for navigation and enemy submarines.
