Bangladesh Navy

Bangabandhu

In June 2001, the Bangladesh Navy commissioned a heavily modified Ulsan-class frigate as the most modern ship in its fleet and named it BNS Bangabandhu. However, controversy regarding alleged corruption in the procurement process and faulty design led the frigate to be decommissioned for several years. The ship was eventually recommissioned in 2007.
