The Bangladesh Navy (BN) has received the two Shadhinota (Type C13B)-class corvettes it ordered from China in late 2015, according to a statement by Inter-Services Public Relations (ISPR), the media wing of the Bangladeshi military.
The two new 90-m long ships, which have been named Sangram (with pennant number F 113) and Prottasha (F 113), were handed over to the service on 28 March and arrived at the naval base in Chittagong on 27 April, said ISPR.
The ships, which are expected to enter service in the near future, are the third and fourth of the class. Both ships were built in Wuhan by China's Wuchang Shipbuilding Industry Group, with Sangram being launched in February 2018 and Prottasha two months later.
These vessels follow BNS Shadhinota (F111) and BNS Prottoy (F112), both of which were launched in Wuhan in late 2014 and entered service in March 2016, according to Jane's Fighting Ships .
However, images show that, unlike the first two ships of the class, the latest two appear to be equipped with a more advanced phased-array radar, which, according to the website sina.com, could be the SR2410C 3-D multifunctional radar, although no official confirmation has emerged.
The Type C13B corvettes, the design of that is based on China's Type 056-class corvettes, have a beam of 11 m, a draught of 4.4 m, a full-load displacement of 1,330 tonnes, and top speed of about 25 kt. Each of the ships has a complement of 78, including 60 crew and 18 officers.
The Type C13B class is fitted with a 76 mm H/PJ-26 main gun, two 30 mm H/PJ-17-1 close-in weapon systems, an FL-3000N eight-cell launcher for surface-to-air missiles, four C-802 (YJ-83) surface-to-surface missiles, and a helipad.
Although the combat systems of the Type C13B are broadly similar to those of the Type 056, the BN ships lack a sonar system and anti-submarine weapons.
