Jiangnan Shipyard
A Type 0105 with hull number 595 was selected to be redesigned to incorporate Type 404 gas turbine engine, and the general designer for the boat redesign was Chen Xie-Wen (陈协文), with Li Meng-Xuan (李荫轩) as the general designer of the propulsion system. The construction of the gas turbine powered boat was assigned to Jiangnan Shipyard, and the boat was handed to PLAN in 1967. Due to the significant weight change, original weaponry had to be adjusted and additional measure had to be taken into consideration for stability. The first stage of sea trials was plagued with problems, starting with the gas turbine engine could not start, so air inlet had to be redesigned. A much more serious problem was that some of the components broke apart and damaged the engine, which could only be taken out at Jiangnan Shipyard, so the boat had to be towed back to the shipyard for repair. As a result, the aluminum alloy used to make these components was replaced by steel, and frame that supports the components was also redesigned. In addition, manufacturing technique was also modified, with arc welding replaced the original spot welding.
