The Type C13B light frigates ordered by the Bangladesh Navy in 2013. The ships improved on the basis of Type 056. It replaced the weapon and radar system different from the domestic version and cancelled the anti-submarine capability. The most advanced frigate in the media, once known as China's export, its shape has been fully integrated with the overall trend of international light frigates.

The C13B corvette is the surface warfare corvette variant of the Type 056 corvette for the Bangladesh Navy. The corvettes displace 1,330 tons and are 90 metres (300 ft) in length. It is armed with a H/PJ-26 76 mm gun, C-802A anti-ship missiles, FL-3000N SAMs and two H/PJ-17 30mm remote controlled gun turrets. The C13B lacks sonar and ASW weapons.
