Coastal vessel, fast torpedo boat, like the 123K A-11 with a second turret.
The Type 025 torpedo boat, or Huchuan-class, was developed by the PLAN in the 1960s to replace their Soviet Pr.123K and Pr.183 torpedo boats, seeking to combine the metal hull design of the Pr.123 and the firepower of the Pr.183. They acquired the plans for the unsuccessful Soviet Pr.184 torpedo boat, and used it as the basis for their new torpedo boat. It was designed by the 701 Research Institute and the first prototype was built in 1963, albeit without hydrofoils to test the basic hull design. The 701 institute designed a new retractable hydrofoil and the first hydrofoil-equipped prototype was built in 1964, and the first production boat arriving in 1968. It was constructed out of aluminium alloy and armed with Soviet weapons and systems. Multiple variants of it exists, most notably the Type 026 which changes the layout, having weapon mounts at both fore and aft.
It has the distinction of being the first hydrofoil warships to be mass-produced, and about 107 Type 025 boats were built in total. They were also exported to friendly nations like Tanzania or Romania, and it is speculated that some still remain in service today, possibly used as training vessels.
