H/PJ-45 130mm naval gun

The H/PJ-45 is a single-barreled 130mm naval gun employed by the People's Liberation Army Navy.^[1] This naval gun, which was designed in 2005, was first installed on the Type 052D destroyer and later on the Type 055 destroyer.^[2][3] When name of the gun is also given as the H/PJ-38 in some English and Japanese literature. This weapon's official designation, according to Taiwanese military journalist Lu Yi, is H/PJ-45.^[2]

The H/PJ-45 was designed by the Norinco, through experience gained from the reverse engineering of the Soviet twin-barrel AK-130 130mm naval gun.^[1] The H/PJ-45 was manufactured by the Inner Mongolia Second Machinery Manufacturing Factory.^[4]

Chen Dingfeng was the general designer of the H/PJ-45. Dingfeng was also the general designer for the Type 79 100 mm naval gun, the Type 210 100 mm naval gun, and the H/PJ-26 76 mm naval gun. The Chinese navy was unsatisfied and did not let the AK-130 counterpart go into production, despite all performance parameters being met.^[5] The Chinese Navy determined the AK-130 to be out-of-date,^[3] which led to the creation of the H/PJ-45 program in 2005.^[6]
