Durjoy-class LPC

The Durjoy class is a class of semi stealth large patrol craft(LPC) of the Bangladesh Navy. A total of eight ships of this class are planned and two are serving with Bangladesh Navy from 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 with People's Liberation Army Navys Type 056 Jiangdao corvette suggesting Durjoy Class is a scaled down version of the Type 056 corvette. The first, Durjoy (P 811), was launched on August 26, 2012, while the second, Nirnul (P 813), was launched on September 27, 2012. Both ships arrived in Bangladesh in February 2013. The ships were commissioned August 29, 2013.

On 30 June 2014 Bangladesh Navy signed a contract for next two Durjoy-class LPCs with Khulna Shipyard. These ships will be made here under ToT from China. Keel laying of the ships will be done at the end of 2014 or the beginning of 2015. Bangladesh Navy has a plan to acquire a total of eight this type of ships.

Design
These ships are of 64.2 meters long, 9 meters wide and 4 meters drought with a displacement of 648 tonnes. The ships have a Bulbous bow suggests these ships are to patrol the vast sea area of Bangladesh. The design also suggests the ships are very stable in heavy sea states and has 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. The range of the ships is 2500 nautical miles (kn) and endurance is 15 days. They have a compliment of 60 crews. According to CSIC officials speaking to Defense Media Network at LIMA 2013, these are cost-effective warships, able to perform both strike missions at ranges of about 40 kilometers as well as undertaking limited anti-submarine warfare (ASW) operations.

Electronics
Primary sensors include a TR-47C gunfire control radar with built-in electro-optical sensors, an SR-60 search radar, and an ESS-3 bow mounted sonar with an effective range of about 8000 meters. A JRCSS combat management system (CMS) with at least three multifunction consoles is also fitted.

Armament
The LPCs are armed with a single 76.2mm NG-16-1 automatic cannon, two twin 25mm cannon mounted amidships, four C-704 surface to surface missiles (SSM) mounted aft, and two forward-mounted six-barreled RDC depth charge rocket launchers.
