Career

BNS Nirbhoy was commissioned to Bangladesh Navy on 1 December 1985. She is based at Chittagong.

In November 2008, BNS Nirbhoy along with BNS Abu Bakar and BNS Madhumati intercepted Myanmar Navy ships at a disputed region of Bay of Bengal where they were supporting an exploration of oil and gas fields.[2]

Electronics

The ship uses a Pot Head radar as primary electronics. It is a surface search radar which is effective in performing mine laying operations. 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 increased detection range by avoiding buffeting generated by the hull.

Armament

The primary armaments of the ship are two twin 57mm 70-cal Type 76 DP guns and two twin 25mm 60cal Type 61 guns. Besides these she carries a variety of weapons to perform ASW missions. The ASW weapons are four RBU-1200 (Type 81) (5-barrel) ASW rockets, two BMB-2 ASW mortars and two depth charge rails with 20 depth charges.
