The Bangladesh Navy (BN) commissioned two locally built Chinese Durjoy-class large patrol craft (LPC), Durgam (P 814) and Nishan (P 815), along with two 32 m submarine handling tugs, at its Titumir naval base in Khulna on 8 November. The vessels were built at the navy-operated Khulna Shipyard (KSY).
The BN operates two similar Chinese-built Durjoy-class missile-armed, anti-submarine warfare (ASW) capable LPCs that were built by China Shipbuilding Industry Corporation's (CSIC’s) Wuchang Shipyard and delivered to the BN in late 2012.
It has taken KSY about 24 months to build the second pair to China Classification Society build standards, with material kits and technical assistance provided by CSIC. According to KSY officials, the warships cost about BDT8 billion (USD96 million) to build in-country, a savings of about 25% over the cost of importing them from overseas.
KSY signed the LPC contract with CSIC’s trading arm – China Shipbuilding & Offshore International Company (CSOC) – on 15 July 2014 after floating an international tender for the LPC project in December 2013. The contract went into effect on 1 Feb 2015 for a planned delivery date of 31 January 2018.
Both hulls were laid down on 6 Sep 2015, with Durgam entering the water in late December 2016 and Nishan in mid-March 2017.
Although the external dimensions of the Chinese- and KSY-built LPCs are similar, there are detail differences in the superstructure, machinery layout, and combat systems.
According to KSY, the locally built 64.2 m, 650-tonne warships are equipped with two Chinese-built Pielstick 16-cylinder diesels, each rated at 5,702 kW (with two fixed-pitch propellers), instead of the three engines (and three propellers) of the earlier pair. In addition, the new LPCs are not fitted with surface-to-surface missiles and anti-submarine rocket depth charge launchers.
