China first received a single unit of Soviet {{sclass2|Osa|missile boat}} in January 1965, and four more in 1966 through 1967 and the last two in 1968. The Hudong Shipyard built the Chinese version as Type 021-class missile boat at a rate of ten boats per year with several different versions. The majority of this class is being transferred to reserve status. Several dozen remain active and these active units are being rearmed with C-101 supersonic anti-ship missiles. Bangladesh Navy Type 021 missile boats rearmed with C-704 high subsonic anti-ship missiles. These boats are effectively used in swarm missile attacks.
''Huangfeng'' class
The Huangfeng-class missile boat is the direct Chinese copy of Soviet Osa-class missile boat. Around 130 were built, including exported units. This class consists of several versions with different armament. Most are armed with twin 25mm guns, while some are armed with a single AK-230 gun mount. The majority lack the fire control radars but some do have a radar radome aft (between the two missile launchers).
The Chinese engine is an improvement of the Huangfeng class over the original Soviet M503A diesel engine. The range of the boat is more than doubled without significant proportional increase of fuel consumption. However, due to the limited size of the boat, the actual endurance is not drastically increased because there is not enough extra space to store additional provisions needed for the longer endurance. Other improvements over the original Soviet Osa-I class included a much improved fire extinguishing system and life support system.
Hola class
A single unit of Type 021 without the gun is called Hola-class missile boat. The Hola-class missile boat is slightly larger than the Huangfeng class, with the length increased to more than {{convert|42|m}}. The boat has an additional radar radome that is also onboard many Huangfeng class boats.
There is an additional pair of missile launchers added, and this pair can be readily removed when needed. The mast is redesigned so that it can be folded down when entering the protective cave in the mountains. The design is more successful than the Homa class and despite its age, the Hola-class boat remains in active service like a few of its Huangfeng class cousins. This class is also known as Hela class.
''Houdong'' class
{{see also|Tondar-class fast attack craft}}
The Houdong-class missile boat is the newest upgrade of the Type 021-class missile boat. The new boat is modified to carry C-801/802/803 missiles. It retains the hull of the original Type 021.
Although the design was successful, more capable missile boats such as the Houxing-class missile boat were already becoming available, so the Houdong class was geared for export. Iran is the first customer and the one in Chinese inventory is used for training foreign crews, and as a demonstrator to other potential customers, as well as other test and trial purposes.
