Durjoy-class corvette

The Durjoy class is a class of semi stealth corvettes of the Bangladesh Navy. Only two ships were planned and both are delivered to the Bangladesh Navy in 2012.

Design
The Durjoy class consists of two corvettes 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.

Two ships were built, BNS Durjoy and BNS Nirmul. Both vessels were built by 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 two ships are of 64 meter length with a displacement of 650 tonnes with 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 seas and has speed and range to support long missions. The first, Durjoy (P 811), was launched on August 26, 2012, while the second, Nirmul (P 813), was launched on September 27, 2012. Both ships arrived in Bangladesh in February 2013. The LPC are powered by triple Pielstick diesels driving three screws for a top speed of 28 knots. Range is 2500 nautical miles (nm) and endurance with a crew of 60 is 15 days. According to CSOC 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.

Their primary mission is to serve with the Corvette Squadron of the Bangladesh Navy, protecting both the fishing fleets and the oil and gas fields and other Economic Zones. In addition, they can also serve in an anti-ship role and undertake limited anti-submarine warfare (ASW) operations.

Armament
The LPC 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.

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.
