Type 206-class gunboat

The Type 206 class gunboat is a gunboat of the People's Republic of China's People's Liberation Army Navy. Also known as the Huludao class, it is a simplified version of the Type 037 class submarine chaser (also known as the Hainan class). Used for patrol duties, it has slightly reduced displacement, but has an enlarged superstructure.

Construction
A total of 7 of this class were sold to Algeria in the period of 1990 through 1991. At least a single unit remaining in PLAN service for training and patrol missions, unconfirmed reports claiming that the Chinese unit has been up gunned. The specification of Type 206 class gunboat is generally similar to that of Type 037 class submarine chaser except for its much lighter armament, making it more suited for patrolling friendly coastal areas.

Designation
Although the Chinese classify this class as gunboat, it is actually much more accurate to fit the classification of the patrol boats for various reasons. For example, the missions and weaponry are that of patrol boats and due to the drastic reduction of the number of crews, the living conditions is significantly improved. In fact, after evaluating the class, the Chinese eventually developed much smaller 80 ton type harbor security / patrol boats to replace the obsolete and aging Shantou, Beihai, Huangpu and Yulin classes of gunboats performing the patrol duties, thus breaking the long tradition of the PLAN of having no dedicated patrol boats.
