The compact single-barrel 100mm gun is a Chinese copy of the French Creusot-Loire T100C dual-purpose (surface strike and air defence) compact 100mm naval gun design. The system is a lightweight version of the French 100mm naval gun, with a combat weight of 19 tonnes including gunhouse, deck, and magazine. The PRC purchased two examples of the Creusot-Loire T100C in the 1980s, and one of them was installed on the single Type 053HT-H (Jianghu-IV class) frigate Siping (544) for trial.
The Chinese-made version of the Creusot-Loire T100C has been installed on the Type 052B Luyang-I class DDG, Type 052C Luyang-II class DDG, Type 051C Luzhou class DDG, and Type 054 Jiangkai-I class FFG.
