The Dogsuli-class frigate (Daekanese: 독수리, meaning "eagle") is a class of guided-missile frigates of the Daekanese People's Army Navy. The ships of the class were the first Daekanese vessels that were purpose-built to carry anti-ship cruise missiles, and they were also the first to feature a combined gas and gas (COGAG) propulsion system. The Dogsuli-class was intended to be used in hit-and-run tactics, hence the -for the time- advanced propulsion system that enabled it to reach speeds up to 33 knots. However, it was that exact propulsion system that was the cause of several teething problems at the start, as well as slow initial production rate. Despite its initial problems, upgraded variants of the Dogsuli remain in active DPAN service, with their retirement process beginning only in 2017.
