After 1971 we had inherited only a tiny base workshop which was located outside of the premises of BN dockyard. The need for a strong repair facility was immediately felt with the gradual expansion of Bangladesh Navy particularly after BN had acquired ex-British frigates in 1977. When these frigates were sent to Singapore for repair and refit, it was found very expensive. Thereafter, the higher authority felt the necessity of a full fledged dockyard. The Expansion of yard repair facilities, then continued, at a steady pace.

Purchase of a floating dock in 1980 was a major milestone for BN Dockyard as it met the docking requirement of all major BN ships. Finally in 01st March 1988 BN DOCKYARD was commissioned.
 BN Dockyard has now come a long way, to be able to support the growing BN fleet ,of about 80 ships with old and diversified equipment, machinery and weapons.
