Iranian Navy 'Thondar' Class (Hudong) fast attack craft (FAC)

The Houdong is a Chinese missile boat, based off of the Huangfeng missile boat, itself a copy of the Russian Osa class missile boats. It is armed with a four round launcher for the C-802 cruise missile, as well as a turreted twin 30mm cannon and crewed 23mm cannon for self defense. In total China reportedly sold Iran between 10 and 40 Houdong missile boats, officially named Thondar in Iranian service and possibly more than 80 C-802 anti-ship cruise missiles during the mid-1990s. These formed a major part of Iran's offensive naval capabilities during the 1990s
