The Durjoy class is a class of large patrol craft (LPC) of the Bangladesh Navy. A total of eight ships of this class are planned, and two have served with the Bangladesh Navy since 2013.
History
The Durjoy class consists of two large patrol craft (LPC) built for the Bangladesh Navy, designed in response to the Government of Bangladesh's long term plan of modernizing the armed forces of Bangladesh to make it a three-dimensional deterrent force.
Initially, a contract was signed in 2009 for two ships to be built at Wuchang Shipyard in China. These ships have a significant resemblance to the People's Liberation Army Navy Type 056 Jiangdao corvette, suggesting that the Durjoy class is a scaled down version of the Type 056 corvette. The first, BNS Durjoy (P 811), was launched on 26 August 2012, while the second, BNS Nirmul (P 813), was launched on 27 September 2012. Both ships arrived in Bangladesh in February 2013.[1] The ships were commissioned on 29 August 2013.[2]
On 30 June 2014 Bangladesh Navy signed a contract for the next two Durjoy-class vessels with Khulna Shipyard. These ships will be made in Bangladesh under a ToT from China. Keel laying of the ships was done on September 6, 2015.[3] The Bangladesh Navy plans to acquire eight vessels of this class.
Design
These ships are 64.2 metres (211 ft) long, 9 metres (30 ft) wide and have a 4 metres (13 ft) draught with a displacement of 648 tonnes. The ships have a bulbous bow shape, which suggests they are designed to sustain heavy sea states. The ships have speed and range to support long missions. The LPCs are powered by triple Pielstick diesels driving three screws for a top speed of 28 knots (52 km/h; 32 mph). The range of the ships is 2,500 nautical miles (4,600 km; 2,900 mi) and endurance is 15 days. They have a complement of 60 crews. According to CSIC officials speaking to Defense Media Network at LIMA 2013, these are cost-effective warships, able to perform strike missions at ranges of about 2,500 nmi (4,600 km; 2,900 mi) as well as undertake limited anti-submarine warfare (ASW) operations.
Two Durjoy-class ships are currently under construction at KSY for dedicated ASW operations which will have torpedo launchers besides other armaments.
Electronics
The primary sensor of the ship of this class is a Type 360 (SR60) Surface Search, E/F band radar. They carry a Russian MR-123-02/76[4] Fire Control Radar for 76.2mm H/PJ-26 gun and two I-band Type 347G Radar (Rice Bowl) for 20mm cannon. For fire control of C-704 missiles, these ships use Type 352 (Square Tie) I-band radar which can be used as surface search radar also. They use ESS-3 bow mounted sonar with an effective range of about 8,000 metres (26,000 ft) for underwater detection. A JRCSS combat management system (CMS) with at least three multifunction consoles is also fitted in the ships.
Armament
The LPCs are armed with a single 76.2 mm (3 in) H/PJ-26 naval gun and four C-704 surface to surface missiles (SSM) mounted aft. Besides, ships of this class have two Oerlikon 20 mm cannon mounted amidships which can be used for anti-aircraft role. For their ASW role Durjoy-class ships have two forward-mounted 6-tube EDS-25A 250 mm (10 in) ASW rocket launchers and decoy launchers.
