The Ulsan-class frigate is a class of multi-purpose guided missile frigates built by the Republic of Korea.

The Ulsan class is a light frigate built by Hyundai Heavy Industries Co., Ltd. and Daewoo Shipbuilding & Marine Engineering Co., Ltd. The frigates are 103.7 metres (340 ft 3 in) in length with top speed of 34 knots (63 km/h; 39 mph) and range of 8,000 nautical miles (15,000 km; 9,200 mi) at 16 knots (30 km/h; 18 mph).

In June 2001, the Bangladesh Navy commissioned a heavily modified Ulsan-class frigate as the most modern ship in its fleet and named it BNS Bangabandhu. However, controversy regarding alleged corruption in the procurement process led the frigate to be decommissioned for several years. The ship was eventually recommissioned in 2007.
