BNS Durjoy (1982)

BNS Durjoy was a Type 037-class submarine chaser of the Bangladesh Navy. She served the Bangladesh Navy from 1982 to 1995.

Design
Powered by four 4,000 hp PCR/Kolomna Type 9-D-8 diesel engines that drive four propellers, Durjoy had a maximum speed of 30.5 kn. She had a range of 1,300 nmi at 15 kn.

Armament
The ship's primary armament consisted of two twin 57mm guns. Anti-aircraft armament consisted of two twin 25mm guns. For anti-submarine warfare (ASW), she was equipped with four RBU-1200 anti-submarine rocket launchers and two depth charge racks with 18 depth charges. She could carry up to 12 mines.

Electronics
Durjoy was equipped with one Pot Head radar for surface search. For ASW operations, she uses Chinese SJD-3 telescoping high frequency active sonar. Instead of being fixed to the hull, SJD-3 has a telescoping arm, so when not in use, the sonar is stored in the hull, and when deployed, the sonar is lowered into water several meter below the hull, thus increasing the detection range by avoiding buffeting generated by the hull.

Career
The ship was purchased for 232 million Bangladeshi taka ($11.5M as of 1982).

She was commissioned into the Bangladesh Navy as Durjoy on 10 September 1982. She was based at Chittagong, as part of Escort Squadron 81.

Durjoy was damaged in the April 1991 Bangladesh cyclone. She was subsequently repaired.

In 1995, she was damaged beyond repair. After serving the Bangladesh Navy for about twelve years, the ship was decommissioned.
