The Cheng Kung class are based on the long-hulled version of the Oliver Hazard Perry-classfrigates of the United States Navy but with modifications. The class was intended to be built in two batches, with Batch I built to the standard design, and Batch II constructed to an improved design, incorporating new technologies.[1] The standard initially had a light displacement of 3,100 long tons (3,100 t) and a full load displacement of 4,200 long tons (4,300 t). They initially measured 455 feet 5 inches (138.81 m) long overall and 413 ft 1 in (125.91 m) at the waterline with a beam of 45 ft (14 m) and a maximum draft of 18 ft 8 in (5.69 m). They are powered by two General Motors LM-2500 gas turbines turning one shaft connected to a controllable pitch propeller, creating 41,000 shaft horsepower (31,000 kW). They also have two drop-down auxiliary propulsion units that create 720 hp (540 kW). This gives them a maximum speed of 29 knots (54 km/h; 33 mph).[1] They carry 587 long tons (596 t)[2] of fuel giving them a range of 5,000 nautical miles (9,300 km; 5,800 mi) at 18 knots (33 km/h; 21 mph).[1] The ships have four 1,000 kW diesel alternator sets for generating electricity. For additional stability in heavy seas, the ships have fin stabilizers. The frigates have a crew of 206 including 13 officers and an air group of 19.[2]
The ships mount SPS-55 surface search radar, SPS-49(V)5 air search, Mark 92 fire control radar, STIR 24 missile fire control radar and Mark 90 Phalanx fire control radar. They are also equipped with DE 1160B hull-mounted sonar and are capable of using the ATAS towed passive sonar or the SQR-18A towed sonar. For electronic countermeasures, they mount the Chang Feng IV suite, which consists of the SLQ-32(V)5 radar warning system and the Sidekick radar jammer, and the SLQ-25 Nixie torpedo decoy system. The ships are equipped with the Prairie-Masker acoustic signature reduction system.[2] The ships came designed with a hangar and aft helicopter deck capable of operating two helicopters.[3] However, the ROCN had difficulty acquiring helicopters capable of operating from the class until they obtained the S-70C Thunderhawk helicopters from the United States. Though capable of operating two, only one is kept housed aboard the frigates. The ships use the Recovery Assist, Secure and Traverse (RAST) haul-down system for their helicopters.[1][3]
Upgradesedit
The displacement of the Cheng Kung-clas frigates has varied over time. In 2009, it was reported that the vessels had a light displacement of 2,750 long tons (2,790 t) and a full load displacement of 4,105 long tons (4,171 t). Furthermore, their draft increased to a maximum of 24 ft 5 in (7.44 m).[3] This increased again by 2013, with the ships displacing 3,207 long tons (3,258 t) light with a maximum draft of 28 ft 3 in (8.60 m).[4]
The Cheng Kung class was initially fitted with eight Hsiung Feng II SSMs, instead of the Harpoon missiles that the Oliver Hazard Perry class used. Ships of the class began refitting with four Hsiung Feng III (HF III) missiles, replacing four of the Hsiung Feng II missiles after the new HF III missiles entered production.[5] In addition, the ROCN ordered Harpoon missiles for use by the Cheng Kungs in September 2000.[2] After the US stopped supporting the SM-1 and their associated launch system support was taken up by NCSIST which also implemented an upgrade program for the missiles. Upgrades to the SM-1 include a better rocket motor and an active seeker.[6]
The class's Mk 75 main guns have been upgraded and have an improved firing rate of 100 rounds a minute.[7]
Construction and careeredit
The fourth ship of the Cheng Kung class, Yueh Fei was laid down on 5 September 1992 by the China SB Corp., at their yard Kaohsiung City, Taiwan. The frigate was launched on 26 August 1994, and commissioned on 7 February 1996. The ship was named for the famous Chinese commander Yue Fei.[4] The Cheng Kung class formed the 146th Frigate Squadron.[3]
