The former Untied States Navy's USS Joseph Hewes (FF-1078) Knox-class fighting frigate stands in as the modern Taiwanese Navy's ROCN Lan Yang (FFG-935). The ship largely retains the original's form-and-function and continues service well past its useful operational service life. The original hull was ordered on August 25th, 1966 and laid down by the Avondale Shipyard of Louisiana on May 14th, 1969. She was launched to sea on March 7th, 1970 and formally commissioned into USN service on April 24th, 1971.

The vessel served up until decommissioned on June 30th, 1994 and was struck from the USN register on January 11th, 1995 - then sold off to Taiwan where, today, she is a hull having surpassed fifty years of on-water operations. In Taiwanese service, the class is known as the Chi Yang-class and the collection of six warships (formerly eight) has been in service for nearly 30 years (the youngest hull being 23 years old as of this writing - 2022).

The Knox-class design displaced 3,215 tons standard and up to 4,200 tons under load. Dimensions included a bow-to-stern length of 438 feet, a beam of 46.8 feet, and a draught of 24.8 feet. Power was served from 2 x CE boiler units of 1,200psi feeding 1 x Westinghouse geared steam turbine developing 35,000 horsepower to a single shaft astern. This arrangement drives the hull to speeds of just over 27 knots.

Aboard the Taiwan ship is a mix of modern search / surface-search radars, the Mk 68 Fire Control System (FCS), and a bow-mounted and towed sonar array. Electronic Warfare (EW) is handled through the AN/SLQ-32 suite.

Armament includes a 5" /54 caliber turreted deck gun, a single Sea Sparrow anti-aircraft missile launcher, 1 x 8-cell Mk 16 surface-to-surface launcher, and 4 x Mark 46 series torpedo tubes. Over the stern is carried a navalized helicopter for the Anti-Submarine Warfare (ASW) / anti-ship role as well as Search and Rescue (SAR) and spotting sorties.

As a whole, the vessel fulfills a critical role in the Republic of China Navy (ROCN) but is well past due in its capabilities when concerning modern naval warfare. The Chi Yang-class consists of six total former USN vessels obtained in the Knox-class standard. This includes FFG-933, FFG-934, FFG-937, FFG-938, and FFG-939 (FF-932 and FFG-936 since being retired).©MilitaryFactory.com
