ROCS Chang Chien (張騫, PFG2-1109) is the seventh of eight Taiwanese-built Cheng Kung-class frigates based on the United States Oliver Hazard Perry class.

Laid down in June 1996 and launched in April 1997, Chang Chien was commissioned in November, 1998. All of these Taiwanese frigates have the length of the later Oliver Hazard Perry-class vessels, but have a different weapon and electronics fit.^[2]

Like her sister ships, Chang Chien was built under license by China SB Corp. at Kaohsiung City, Taiwan, ROC.

As of 2005, Chang Chien is homeported at Tso-Ying naval base.

In 2025 the Chang Chien's 76mm gun failed during a live fire exercise with the barrel exploding. No one was injured in the accident.^[3]

Chang Chien is named after Chang Chien (張騫) (195 BCE – 114 BCE), who served as an emissary to the nation-states in today's Central Asia and later as a general for the Han dynasty. He was famous for not-giving up his emissary mission even when captured by Xiongnu and forced to live among them for many years. Chang Chien was also instrumental for eventual Han conquest and colonization of the region now known as Xinjiang.
