ROCS Chang Chien (PFG2-1109) is a frigate warship of the modern Republic of China Navy (ROCN - Taiwan). The warship is one of ten hulls belonging to the 4,200 ton displacement Cheng Kung-class. While the Taiwanese ship was constructed in Taiwanese waters, its design form-and-function is taken (under license) from the proven American Oliver Hazard Perry (OHP) class. The warship continues to serve the ROCN as of this writing (August 2022) and homeports out of Tsoying, Taiwan along the country's southwestern tip.

The OHP class of fighting frigates represents a late-Cold War era warship constructed from 1975 until 2004 to the tune of 71 total hulls. They were used primarily by the United States but many were sold off to allies in the years following including Turkey, Egypt, Poland, and Pakistan. The United States Navy no longer makes use of the ship type and is set to bring back a standardized frigate design through the new, all-modern "Constellation-class" detailed elsewhere on this site.

Chang Chien was laid down by China Shipbuilding Corporation (China SB Corporation, Kaohslung) on December 4th, 1995 and launched on May 14th, 1997. She was formally commissioned into service on December 1st, 1998.

Dimensions of the vessel include a running length of 453 feet with a beam of 47 feet. Power is from 2 x General Electric LM2500-30 gas turbines developing 40,000 horsepower to a single shaft astern. This provides the ship with a headway maximum speed of 29 knots.

Aboard is a crew of 217 made up of officers, enlisted, and a modest flight crew. The flight crew supports a single Sikorsky S-70C-1/2 navalized helicopter over the stern helipad with integrated hangar facilities for optimal at-sea operations. The helicopter can be equipped for Anti-Submarine Warfare (ASW), anti-ship, Search and Rescue (SAR), and other over-water sorties as needed.

Installed systems include the AN/SPS-49 air-search radar, the AN/SPS-55 surface-search radar, and several fire direction / control radars. Electronic Warfare (EW) is handled through the AN/SLQ-32(V)2 and AN/SLQ-32(V)5 suites.

Armament is led by a 76mm OTO-Melara turreted deck gun over the forecastle. There is an Mk 13 Surface-to-Air Missile (SAM) launcher for SM-1MR missiles as well as quad-launchers housing Hsiung Feng II and HF-3 medium-ranged SAMs. Beyond this is a typical array of ballistic solutions including 2 x 40mm Bofors Anti-Aircraft (AA) guns and a single 20mm Phalanx Close-In Weapon System (CIWS). The warship is also fitted with 2 x Mark 32 triple-torpedo tubes for submarine-hunting and ship-neutralization efforts.
