The Type 037 class submarine chaser, also known as the Hainan class, is a class of submarine chaser of the People's Republic of China's People's Liberation Army Navy, designed by China to replace the Soviet S.O.-1 class submarine chaser. Early units had Dual Purpose Mk.26 76.2 mm guns and Russian RBU-1200 ASW rocket launchers, but eventually, these were replaced by Chinese Type 66 twin 57 mm guns and Type 81 ASW rocket launchers (the Chinese version of RBU-1200). The original Skin Head radar has been replaced by the Pot Head radar. In addition to ASW missions, these simple yet effective units are also capable of a wide variety of missions such as mine laying and patrol.
