A ship brought Bangladesh's first submarines named "Nabajatra" and "Joyjatra" to Chittagong Port from China on December 22 last year. The submarines were handed over to Bangladesh on November 14.
The Type 035G-class submarines were assembled at Chinese state-owned Liaonan shipyard in the Dalian state.
Bangladesh paid a reported $203m for the submarines, a deal that reflects the country’s growing economic and defence ties with Beijing.
The submarines, also known as Ming-class, are a class of diesel-electric submarines of the People’s Liberation Army Navy. A total of 12 were built and commissioned between 1990 and 1999. They are 76 metres in length and 7.6 metres in width.
The naval personnel of both the countries completed a sea trial and real training to operate the submarines, an ISPR release said after their arrival in Chittagong.Also Read- Two submarines added to Bangladesh armada
